Question 1Health Care Sector and Career Awareness

Under the NSQF, what does the qualification level of a Health Care General Duty Assistant typically indicate?

  1. The specific hospital department where the worker must be posted
  2. The number of years the worker has spent in formal schooling
  3. The complexity of skills, autonomy and responsibility associated with the job role Correct answer.
  4. The maximum salary the worker can ever earn in the sector

Explanation

NSQF levels describe learning outcomes in terms of skill complexity, autonomy and responsibility, not pay or posting. A given job role is mapped to a level based on these outcome descriptors. Salary, schooling years and department are separate matters.

Question 2Health Care Sector and Career Awareness

A student wants to work as a General Duty Assistant in a hospital. Which body of knowledge is most central to that role?

  1. Income tax computation for hospital staff
  2. Architectural drawing of hospital buildings
  3. Marketing of hospital insurance products
  4. Basic nursing care and patient hygiene assistance Correct answer.

Explanation

The General Duty Assistant role centres on basic nursing care, hygiene, mobility and comfort of patients. Tax, building design and insurance marketing belong to other occupations. The qualifier 'most central' points to direct patient care.

Question 3Health Care Sector and Career Awareness

In the Health Care sector, which of these is an example of a primary health care setting rather than a secondary or tertiary setting?

  1. A super-speciality cardiac institute
  2. A private medical college teaching hospital
  3. A district hospital with specialist surgery units
  4. A sub-centre or primary health centre serving a village population Correct answer.

Explanation

Primary health care is first-contact, community-level care such as a sub-centre or primary health centre. District hospitals, super-speciality institutes and teaching hospitals provide secondary or tertiary referral services. The distinguishing feature is the level of first contact and specialisation.

Question 4Health Care Sector and Career Awareness

Which personal protective equipment is most important for a health care worker before entering a patient's room under standard precautions?

  1. Clean gloves when contact with blood or body fluids is anticipated Correct answer.
  2. A hospital identity badge worn on the chest
  3. A stethoscope carried around the neck
  4. A wristwatch with a second hand

Explanation

Standard precautions require gloves when contact with blood, body fluids or non-intact skin is likely. A stethoscope, badge and watch are routine items and do not prevent transmission. The question asks about protection, so only gloves qualify.

Question 5Health Care Sector and Career Awareness

Which of the following best describes the purpose of hand hygiene before and after every patient contact?

  1. To satisfy hospital attendance records
  2. To keep the worker's hands soft and free from dryness
  3. To break the chain of transmission of microorganisms between patients and the worker Correct answer.
  4. To improve the grip on medical instruments

Explanation

Hand hygiene interrupts the chain of infection by removing transient microorganisms acquired during contact. Skin comfort, attendance records and grip are not the clinical purpose. This is a core standard precaution in every health care setting.

Question 6Health Care Sector and Career Awareness

A candidate is choosing between a short-term certificate course and a longer diploma in the health care sector. Which factor is most relevant to making an informed career decision?

  1. The distance of the institute from the nearest railway station
  2. The job roles and further study pathways each qualification opens up Correct answer.
  3. The number of holidays the course allows
  4. The colour of the certificate issued by the institute

Explanation

Career decisions should be guided by the job roles a qualification permits and the pathways for further study or progression. Certificate colour, transport convenience and holidays are peripheral. The relevant criterion is the occupational outcome.

Question 7Health Care Sector and Career Awareness

A health care assistant notices that a patient has slipped to the floor and appears drowsy. What is the correct immediate action?

  1. Lift the patient back into bed alone and continue the routine work
  2. Wait for the next scheduled round to report the incident
  3. Call for help, keep the patient still and inform the nurse in charge without delay Correct answer.
  4. Record the event in the register and leave the patient alone

Explanation

After a fall, the assistant must summon help, avoid moving the patient in case of injury, and report immediately to the nurse in charge. Lifting alone risks further harm and delays assessment. Waiting or leaving the patient unattended is unsafe.

Question 8Health Care Sector and Career Awareness

Which statement correctly distinguishes sterilisation from disinfection?

  1. Sterilisation is used only on the skin of patients
  2. Sterilisation only removes dust and visible dirt from surfaces
  3. Disinfection always destroys bacterial spores as well
  4. Sterilisation destroys all microorganisms including spores, while disinfection reduces most but not necessarily spores Correct answer.

Explanation

Sterilisation kills or removes all microbial life including spores, whereas disinfection reduces most pathogenic organisms but may not eliminate spores. Cleaning removes dirt and is a separate step. Skin antisepsis uses antiseptics, not sterilisation.

Question 9Health Care Sector and Career Awareness

Why is the biomedical waste stream separated by colour-coded bins in a hospital?

  1. To make the bins look attractive in the wards
  2. To reduce the purchase cost of plastic bags only
  3. To count the number of patients treated each day
  4. To ensure each category is handled and disposed of by the method appropriate to its risk Correct answer.

Explanation

Segregation at source ensures that sharps, infectious waste and general waste follow the correct treatment and disposal route. Colour coding is a safety and compliance mechanism, not an aesthetic or accounting one. Cost saving is incidental.

Question 10Health Care Sector and Career Awareness

A patient is being shifted from bed to wheelchair. Which technique best protects both the patient and the health care worker?

  1. Ask the patient to stand quickly while the worker twists the torso
  2. Position the wheelchair close, lock its wheels and use a coordinated transfer with bent knees Correct answer.
  3. Lift the patient with straight legs and a bent back
  4. Pull the patient by the arms from a distance

Explanation

Safe transfer requires the wheelchair close with locked wheels and a coordinated move with knees bent and back straight. Twisting, pulling from a distance and lifting with straight legs and bent back all raise injury risk. The principle is to reduce reach and spinal loading.

Question 11Health Care Sector and Career Awareness

Which measurement is recorded as part of routine vital signs monitoring?

  1. Body temperature Correct answer.
  2. Height at birth
  3. Dental cavity count
  4. Blood group

Explanation

Routine vital signs include temperature, pulse, respiration, blood pressure and oxygen saturation. Blood group, birth height and dental cavity counts are not vital signs. Temperature is the only option in that set.

Question 12Health Care Sector and Career Awareness

A patient's family asks the assistant for the diagnosis written in the case sheet. What is the appropriate response?

  1. Refuse rudely and walk away without explanation
  2. Read out the entire case sheet to the family
  3. Politely explain that the doctor will share clinical information and direct them to the nurse or doctor Correct answer.
  4. Guess the diagnosis from the medicines listed

Explanation

Confidentiality and role boundaries require the assistant to redirect clinical queries to the doctor or nurse. Reading the sheet, being rude or guessing all breach professional conduct. Respectful redirection protects the patient and the worker.

Question 13Health Care Sector and Career Awareness

Which of these best explains why a health care worker should report a needlestick injury immediately, even if the wound looks minor?

  1. Reporting is only needed if the patient is known to be infected
  2. The injury should be hidden to avoid paperwork
  3. Timely reporting allows post-exposure prophylaxis and baseline testing to begin within the effective window Correct answer.
  4. Minor wounds never carry any bloodborne risk

Explanation

Prompt reporting enables baseline testing and post-exposure prophylaxis within the time window in which it is effective. Bloodborne risk exists regardless of whether the source patient's status is known. Concealing an injury endangers the worker.

Question 14Health Care Sector and Career Awareness

In the context of the health care sector, what does the term 'continuum of care' refer to?

  1. The administrative process of billing an insurance claim
  2. A single consultation with a doctor at one point in time
  3. Only the period a patient spends in an intensive care unit
  4. An integrated sequence of services from prevention through treatment to rehabilitation and palliation Correct answer.

Explanation

The continuum of care describes services linked across prevention, treatment, rehabilitation and palliative stages. It is broader than a single consultation or an ICU stay. Billing is administrative and not part of the clinical continuum.

Question 15Health Care Sector and Career Awareness

A student is exploring careers in the health care sector and wants a role focused on restoring movement and function after injury. Which role should the student investigate?

  1. Radiographer
  2. Physiotherapy assistant Correct answer.
  3. Medical records technician
  4. Hospital dietitian

Explanation

Physiotherapy assistants support exercise, movement and functional recovery after injury. Medical records, dietetics and radiography address documentation, nutrition and imaging respectively. The stated goal of restoring movement points clearly to physiotherapy.

Question 16Health Care Sector and Career Awareness

Which statement about the role of a health care assistant in the emergency department is most accurate?

  1. The assistant performs all diagnostic imaging alone
  2. The assistant prescribes medicines without supervision
  3. The assistant supports the team within the scope of the qualification and escalates clinical decisions to senior staff Correct answer.
  4. The assistant independently decides which patients receive emergency surgery

Explanation

Assistants work within the defined scope of their qualification and escalate clinical decisions to senior staff. Deciding on surgery, prescribing or performing imaging alone all exceed that scope. Scope of practice is a central concept in health care careers.

Question 17Health Care Sector and Career Awareness

A hospital wants to reduce the spread of respiratory infection in a crowded outpatient waiting area. Which measure is most directly effective at the source?

  1. Encouraging patients with cough to wear a mask and follow respiratory hygiene Correct answer.
  2. Increasing the number of chairs in the hall
  3. Playing soft music to reduce anxiety
  4. Painting the waiting area in lighter colours

Explanation

Source control through respiratory hygiene and masking of coughing patients directly reduces droplet emission. Painting, extra chairs and music affect comfort or ambience but not transmission. The question asks for the measure effective at the source.

Question 18Health Care Sector and Career Awareness

An assistant is asked to clean a spill of blood on the floor. Which sequence is most consistent with safe practice?

  1. Wipe the spill with a bare hand and a dry cloth
  2. Cover the spill with a chair and leave it for the next shift
  3. Rinse the floor with plain water and resume work immediately
  4. Cordon the area, wear gloves, absorb the spill with a disposable material, disinfect the surface and discard waste as infectious Correct answer.

Explanation

Blood spills require restricting access, using gloves, absorbing the spill, disinfecting the area and disposing of materials as infectious waste. Bare-hand wiping, plain-water rinsing or leaving the spill covered all expose others to risk. The sequence protects workers and the public.

Question 19Health Care Sector and Career Awareness

A health care worker is offered a shortcut that skips the identity check before giving a meal tray to a patient. Why should the worker decline the shortcut?

  1. Patient identification checks prevent errors of misidentification that can cause harm Correct answer.
  2. Skipping the check saves time and is therefore acceptable
  3. Identity checks are only needed for surgical patients
  4. Meal trays are always identical, so identification is unnecessary

Explanation

Identity verification is a safety barrier that prevents wrong-patient errors, including for meals, medicines and procedures. Assuming trays are identical ignores dietary restrictions tied to specific patients. Saving time never justifies removing a safety check.

Question 20Health Care Sector and Career Awareness

Which reasoning best explains why a health care assistant should document a patient's refusal of a prescribed diet?

  1. Documentation is optional because the nurse already knows the patient
  2. Documentation is done to fill empty pages in the register
  3. Documentation creates a record of the refusal, supports continuity of care and protects the worker and patient Correct answer.
  4. Documentation is only needed when the patient accepts the diet

Explanation

Recording a refusal ensures the care team is aware, supports continuity and provides a legal record. Relying on verbal knowledge is unreliable across shifts. Documentation is a professional duty, not a formality.

Question 21Communication and Interpersonal Skills in Health Care

In a hospital ward, a health care assistant greets a newly admitted patient by name, introduces herself, and explains what she will do before touching the patient. Which communication principle does this behaviour best demonstrate?

  1. Respecting patient dignity and informed consent through introduction and explanation Correct answer.
  2. Using technical medical vocabulary to build professional authority
  3. Completing tasks quickly to reduce the patient's waiting time
  4. Avoiding conversation so the patient can rest undisturbed

Explanation

Introducing yourself and explaining a procedure before performing it protects the patient's dignity and supports informed consent, which are core interpersonal duties in health care. It also reduces anxiety and builds trust between the worker and the patient.

Question 22Communication and Interpersonal Skills in Health Care

Which element is a component of the standard communication cycle used in health care settings?

  1. The hospital's procurement budget
  2. Feedback from the receiver back to the sender Correct answer.
  3. The patient's blood group record
  4. The duty roster of the nursing staff

Explanation

The communication cycle consists of a sender, a message, a channel, a receiver and feedback. Feedback confirms that the message was received and understood correctly. Administrative records such as rosters or budgets are not part of the communication process itself.

Question 23Communication and Interpersonal Skills in Health Care

A patient says, 'I am fine,' while looking down, clenching the bedsheet, and speaking in a very low voice. Which interpretation best reflects effective interpersonal observation?

  1. The patient is definitely fine because verbal statements are always more reliable than gestures
  2. The worker should ignore the body language and record the patient as comfortable
  3. The worker should immediately transfer the patient to another ward
  4. The verbal message and body language conflict, so the worker should gently explore the patient's feelings Correct answer.

Explanation

Non-verbal cues such as gaze, muscle tension and voice tone often reveal distress that words conceal. When verbal and non-verbal messages conflict, a skilled worker gently explores the patient's feelings rather than accepting the words at face value. This is a core observation skill in interpersonal communication.

Question 24Communication and Interpersonal Skills in Health Care

Which practice best demonstrates active listening when a patient describes their pain?

  1. Changing the subject to the day's menu to lighten the mood
  2. Summarising the patient's words back and asking a clarifying question Correct answer.
  3. Writing notes continuously while avoiding eye contact
  4. Interrupting to correct the patient's description of the pain

Explanation

Active listening involves attending fully, reflecting or summarising what was said, and clarifying to confirm understanding. Paraphrasing shows the patient they are heard and helps the worker verify clinical details. It also encourages the patient to share more complete information.

Question 25Communication and Interpersonal Skills in Health Care

A patient with a hearing impairment is being admitted. Which communication approach is most appropriate for the health care worker to use?

  1. Shout loudly from the doorway so the patient can hear from a distance
  2. Face the patient, speak clearly at a moderate pace, and use written notes or gestures as needed Correct answer.
  3. Use long complex sentences to convey as much information as possible at once
  4. Speak only to the accompanying family member and ignore the patient

Explanation

Facing the patient allows lip-reading and clear visibility of facial expression, while a moderate pace and supplementary written notes or gestures support understanding. Shouting distorts speech and can appear disrespectful. Addressing the patient directly preserves autonomy and dignity.

Question 26Communication and Interpersonal Skills in Health Care

Which statement best describes the role of empathy in therapeutic communication with patients?

  1. Sharing one's own personal problems to show common ground
  2. Feeling exactly the same emotion as the patient at all times
  3. Understanding and acknowledging the patient's feelings from their perspective Correct answer.
  4. Telling the patient that their feelings are exaggerated

Explanation

Empathy is the ability to perceive and acknowledge another person's feelings while maintaining a professional boundary. It differs from sympathy, which involves sharing the emotion, and from over-identification, which can impair care. Acknowledging feelings helps patients feel understood and supported.

Question 27Communication and Interpersonal Skills in Health Care

A health care worker must break the news to a patient that a test result requires further investigation. Which approach best reflects good interpersonal communication?

  1. Announce the news to the whole ward so everyone is informed equally
  2. Give the news quickly in the corridor and walk away to save time
  3. Use complex clinical terminology to appear authoritative
  4. Sit at the patient's level, use plain language, allow silence, and invite questions Correct answer.

Explanation

Sensitive news should be shared in a private setting, at eye level, using plain language, with time for silence and questions. This respects confidentiality and gives the patient space to process information. Rushed or public disclosure undermines trust and privacy.

Question 28Communication and Interpersonal Skills in Health Care

Which of the following is an example of a barrier to effective communication in a hospital setting?

  1. Using simple, everyday words with the patient
  2. High noise levels and frequent interruptions in the ward Correct answer.
  3. Allowing the patient time to ask questions
  4. Maintaining eye contact at the patient's eye level

Explanation

Environmental noise, interruptions and distractions interfere with the transmission and reception of messages, making them classic physical barriers to communication. Simple language, time for questions and appropriate eye contact are facilitators, not barriers. Recognising barriers helps workers plan better conversations.

Question 29Communication and Interpersonal Skills in Health Care

A patient from a different cultural background avoids direct eye contact and prefers a family member to answer questions. What is the most appropriate response from the health care worker?

  1. Assume the patient is being deliberately rude and end the conversation
  2. Respect the cultural norm while ensuring the patient's own consent and understanding are confirmed Correct answer.
  3. Insist on direct eye contact because it is the only sign of honesty
  4. Refuse to speak with the family member under any circumstances

Explanation

Cultural norms shape gaze, decision-making roles and communication style, so the worker should respect them while still confirming the patient's own understanding and consent. This balances cultural sensitivity with ethical duty. Labelling behaviour as rudeness reflects cultural bias.

Question 30Communication and Interpersonal Skills in Health Care

Which practice best protects patient confidentiality during interpersonal communication?

  1. Sharing patient details on a personal social media group for advice
  2. Telling visitors about other patients in the same ward
  3. Discussing the case loudly in a crowded lift
  4. Discussing the patient's condition only with authorised team members in an appropriate setting Correct answer.

Explanation

Confidentiality requires that patient information be shared only with those who need it for care, in a private setting. Discussing cases in public spaces or on personal social media breaches privacy and may be a legal violation. Visitors have no right to other patients' information.

Question 31Communication and Interpersonal Skills in Health Care

During a team handover, a health care assistant reports a patient's condition. Which communication style best supports patient safety?

  1. Sharing only positive observations to avoid alarming the team
  2. Leaving written notes in an unclear handwriting without verbal confirmation
  3. Structured, concise reporting using a standard format such as situation, background, assessment and recommendation Correct answer.
  4. Vague comments such as 'the patient seems off' without details

Explanation

Structured handover tools such as SBAR organise information so that critical details are not lost and the receiving team can act safely. Concise, accurate reporting reduces errors during transfer of care. Vague or incomplete reports increase the risk of missed deterioration.

Question 32Communication and Interpersonal Skills in Health Care

A patient becomes angry and raises their voice during a procedure. Which response best demonstrates de-escalation through communication?

  1. Threaten the patient with discharge if the behaviour continues
  2. Stay calm, lower your voice, acknowledge the patient's frustration, and offer choices where possible Correct answer.
  3. Raise your voice to match the patient's volume and assert authority
  4. Walk away silently and refuse to return to the patient

Explanation

De-escalation relies on a calm tone, acknowledging the patient's feelings, and restoring a sense of control through choices. Matching aggression or threatening the patient escalates conflict. Acknowledging frustration shows respect and opens dialogue.

Question 33Communication and Interpersonal Skills in Health Care

Which of the following best describes the purpose of using open-ended questions when taking a patient's history?

  1. To restrict the patient to yes or no answers for speed
  2. To avoid documenting the patient's own account
  3. To encourage the patient to describe their concerns in their own words Correct answer.
  4. To test whether the patient knows medical terminology

Explanation

Open-ended questions invite patients to explain their experience in their own words, which often reveals important details that closed questions would miss. Closed questions are useful later for confirming specific facts. The purpose is not to test vocabulary or to speed up the interview at the cost of information.

Question 34Communication and Interpersonal Skills in Health Care

A health care worker notices that a colleague consistently uses a harsh tone with elderly patients. What is the most appropriate professional action?

  1. Join in with the harsh tone so the team appears consistent
  2. Complain about the colleague loudly in front of patients
  3. Ignore the behaviour because it is not the worker's responsibility
  4. Speak to the colleague privately and, if the behaviour continues, report it through the proper channel Correct answer.

Explanation

Professional accountability requires addressing unprofessional conduct, beginning with a private, respectful conversation and escalating through proper reporting channels if needed. Public confrontation or silence both fail the patients. Ignoring the behaviour allows harm to continue.

Question 35Communication and Interpersonal Skills in Health Care

Which statement about the use of touch in therapeutic communication is most accurate?

  1. Touch can convey reassurance but must be used with awareness of the patient's culture, gender and consent Correct answer.
  2. Touch is appropriate only when the patient is unconscious
  3. Touch should never be used in any health care setting
  4. Touch is always appropriate in every situation and with every patient

Explanation

Therapeutic touch can communicate care and reassurance, but its meaning varies across cultures and individuals, so consent and context matter. Unconsidered touch can cause distress or be misinterpreted. Absolute rules for or against touch ignore this complexity.

Question 36Communication and Interpersonal Skills in Health Care

A patient who does not speak the local language needs to understand discharge instructions. Which approach best supports effective communication?

  1. Arrange a trained interpreter and confirm understanding using teach-back Correct answer.
  2. Hand over a written sheet in the local language without checking comprehension
  3. Speak louder and more slowly in the local language until the patient nods
  4. Ask a child relative to translate complex medical instructions

Explanation

A trained interpreter conveys medical meaning accurately and maintains confidentiality, while teach-back confirms that the patient can restate the instructions correctly. Using children as interpreters risks errors and inappropriate burden. Simply speaking louder or handing over a sheet does not ensure understanding.

Question 37Communication and Interpersonal Skills in Health Care

Which of the following is the best example of clear, plain-language instructions for a patient?

  1. Follow the standard pharmacological protocol as indicated
  2. Administer the prescribed oral preparation post-prandially as directed
  3. Commence the therapeutic regimen per the physician's orders
  4. Take one tablet with water after breakfast each morning for seven days Correct answer.

Explanation

Plain language uses everyday words and concrete details such as what to take, how, when and for how long. Clinical jargon like 'post-prandially' or 'therapeutic regimen' is easily misunderstood by patients. Clear instructions improve adherence and safety.

Question 38Communication and Interpersonal Skills in Health Care

A patient repeatedly asks the same question about their medication. Which interpretation and response best reflect effective communication?

  1. The worker should increase the medication dose to reduce the patient's anxiety
  2. The patient is deliberately annoying the staff and should be ignored
  3. The repetition may signal anxiety or misunderstanding, so the worker should re-explain calmly and check comprehension Correct answer.
  4. The worker should tell the patient they have already been told and refuse to repeat

Explanation

Repeated questions often indicate anxiety, memory difficulty or incomplete understanding rather than deliberate provocation. Re-explaining calmly and using teach-back to check comprehension addresses the underlying need. Changing medication is a clinical decision outside the communication role.

Question 39Communication and Interpersonal Skills in Health Care

Which of the following best describes the role of feedback in interpersonal communication between a health care worker and a patient?

  1. It refers exclusively to written performance reports
  2. It replaces the need for the patient to ask questions
  3. It is only needed when the patient complains
  4. It confirms whether the message was received and understood as intended Correct answer.

Explanation

Feedback is the receiver's response that tells the sender whether the message was understood. In health care it allows the worker to adjust explanations and confirm comprehension. It is a continuous part of every conversation, not a response reserved for complaints.

Question 40Communication and Interpersonal Skills in Health Care

During a conversation, a health care worker mirrors the patient's posture and uses a warm, steady tone. Which aspect of communication is being demonstrated?

  1. Formal medical diagnosis of the patient's symptoms
  2. Written documentation of the patient's condition
  3. Administrative scheduling of the patient's appointments
  4. Non-verbal rapport building through body language and paralanguage Correct answer.

Explanation

Posture mirroring and tone of voice are non-verbal and paralinguistic elements that build rapport and signal attentiveness. They operate alongside words to convey warmth and understanding. Documentation, diagnosis and scheduling are separate professional activities.

Question 41Introduction to the Human Body and Basic Health Concepts

In the study of the human body, which level of organisation comes immediately after cells in the correct sequence from simplest to most complex?

  1. Organ systems
  2. Tissues Correct answer.
  3. Organisms
  4. Organs

Explanation

The accepted hierarchy of body organisation runs cells, tissues, organs, organ systems and finally the whole organism. A tissue is a group of similar cells working together, so it sits directly above the cell level. Organs and organ systems are built from tissues and therefore come later in the sequence.

Question 42Introduction to the Human Body and Basic Health Concepts

A health care student is asked to identify the body cavity that contains the heart and lungs. Which cavity is correct?

  1. Abdominal cavity
  2. Pelvic cavity
  3. Thoracic cavity Correct answer.
  4. Cranial cavity

Explanation

The thoracic cavity is the chest space enclosed by the rib cage, and it houses the heart and lungs along with the oesophagus and trachea. The diaphragm separates it from the abdominal cavity below. The abdominal and pelvic cavities hold digestive and reproductive organs, while the cranial cavity holds the brain.

Question 43Introduction to the Human Body and Basic Health Concepts

Which directional term correctly describes the position of the wrist relative to the shoulder?

  1. Medial
  2. Superior
  3. Distal Correct answer.
  4. Proximal

Explanation

Distal means farther from the point of attachment of a limb to the trunk. The wrist lies farther along the arm than the shoulder, so it is distal to the shoulder. Proximal would describe the shoulder relative to the wrist, and superior refers to a higher position in the body as a whole.

Question 44Introduction to the Human Body and Basic Health Concepts

Which tissue type is described as having closely packed cells with very little intercellular matrix and covers body surfaces and lines cavities?

  1. Epithelial tissue Correct answer.
  2. Nervous tissue
  3. Muscular tissue
  4. Connective tissue

Explanation

Epithelial tissue consists of tightly packed cells resting on a basement membrane, with minimal space between cells. It forms protective coverings, linings and secretory surfaces. Connective tissue is defined by abundant matrix, while muscle and nerve tissues are specialised for contraction and conduction respectively.

Question 45Introduction to the Human Body and Basic Health Concepts

During a practical, a student counts 32 permanent teeth in an adult and is asked how many are incisors. What is the correct number of incisors in a complete adult set?

  1. 8 Correct answer.
  2. 4
  3. 6
  4. 12

Explanation

Each jaw carries four incisors, giving eight incisors in the full permanent dentition. Incisors are the chisel-shaped front teeth used for cutting food. The remaining teeth are four canines, eight premolars and twelve molars.

Question 46Introduction to the Human Body and Basic Health Concepts

Which substance secreted in the stomach is primarily responsible for beginning the digestion of proteins?

  1. Pepsin Correct answer.
  2. Lipase
  3. Amylase
  4. Bile

Explanation

Pepsin is a protease secreted in the stomach as inactive pepsinogen and activated by hydrochloric acid. It breaks proteins into smaller peptides. Bile emulsifies fats, amylase digests starch and lipase digests fats, and none of these acts as the main stomach protease.

Question 47Introduction to the Human Body and Basic Health Concepts

A patient's blood report shows a low haemoglobin value. Which function of blood is most directly affected by this finding?

  1. Transport of oxygen Correct answer.
  2. Defence against infection
  3. Regulation of body temperature
  4. Clotting at a wound site

Explanation

Haemoglobin is the iron-containing pigment inside red blood cells that binds oxygen and carries it from the lungs to tissues. A low haemoglobin value therefore reduces the blood's oxygen-carrying capacity. Clotting depends on platelets and clotting factors, defence on white cells, and temperature regulation on blood flow distribution.

Question 48Introduction to the Human Body and Basic Health Concepts

In the human circulatory system, which chamber of the heart pumps oxygenated blood into the aorta?

  1. Left atrium
  2. Right ventricle
  3. Right atrium
  4. Left ventricle Correct answer.

Explanation

The left ventricle receives oxygenated blood from the left atrium and pumps it into the aorta for distribution to the body. Its thick muscular wall generates the pressure needed for systemic circulation. The right side of the heart handles deoxygenated blood going to the lungs.

Question 49Introduction to the Human Body and Basic Health Concepts

Which part of the respiratory system is the main site of gas exchange with the blood?

  1. Trachea
  2. Bronchi
  3. Alveoli Correct answer.
  4. Larynx

Explanation

Alveoli are tiny air sacs at the end of the bronchioles with extremely thin walls surrounded by capillaries. Their large total surface area and thin barrier allow oxygen and carbon dioxide to diffuse between air and blood. The trachea, bronchi and larynx are conducting passages only.

Question 50Introduction to the Human Body and Basic Health Concepts

A person's breathing rate increases sharply during brisk exercise. Which change in the blood most directly stimulates this increase?

  1. A fall in blood pressure
  2. A rise in blood glucose
  3. A rise in carbon dioxide Correct answer.
  4. A rise in plasma protein

Explanation

During exercise, muscles produce extra carbon dioxide, which raises its level in the blood. Chemoreceptors detect this rise and stimulate the respiratory centre to increase the rate and depth of breathing. Glucose, plasma protein and blood pressure changes are not the primary trigger for this response.
