Question 1Airway Management, Ventilation, and Oxygenation

A patient is breathing room air. Which partial pressure of oxygen in arterial blood (PaO2) is most consistent with adequate oxygenation?

  1. 95 mmHg Correct answer.
  2. 40 mmHg
  3. 120 mmHg
  4. 60 mmHg

Explanation

On room air, a normal PaO2 is roughly 80 to 100 mmHg, so 95 mmHg reflects adequate oxygenation. Values near 60 mmHg sit at the steep part of the oxyhemoglobin dissociation curve and signal borderline reserve.

Question 2Airway Management, Ventilation, and Oxygenation

Which device delivers the most reliable and highest fractional inspired oxygen when a patient is breathing spontaneously?

  1. Venturi mask at 40%
  2. Simple face mask at 8 L/min
  3. Non-rebreather mask with reservoir at 15 L/min Correct answer.
  4. Nasal cannula at 4 L/min

Explanation

A non-rebreather mask with a reservoir bag and one-way valves can deliver an FiO2 approaching 0.90 to 1.00. Lower-flow devices mix oxygen with entrained room air and give less predictable concentrations.

Question 3Airway Management, Ventilation, and Oxygenation

Which finding best indicates that a patient's airway is patent and self-maintaining?

  1. Stridor on inspiration
  2. Gurgling with each breath
  3. Snoring respirations
  4. Clear speech in full sentences Correct answer.

Explanation

The ability to speak in clear, full sentences demonstrates airflow through the upper airway and adequate ventilation. Snoring, gurgling, and stridor are all signs of partial obstruction.

Question 4Airway Management, Ventilation, and Oxygenation

What is the most common cause of upper airway obstruction in an unresponsive patient?

  1. Laryngospasm
  2. Foreign body aspiration
  3. Tracheal stenosis
  4. Tongue falling back against the pharynx Correct answer.

Explanation

In an unresponsive supine patient, loss of muscle tone allows the tongue to fall posteriorly and occlude the pharynx. This is why head-tilt chin-lift or jaw-thrust maneuvers are the first step in airway management.

Question 5Airway Management, Ventilation, and Oxygenation

Which oxygen delivery device provides the most precise, fixed inspired oxygen concentration regardless of the patient's breathing pattern?

  1. Simple face mask
  2. Nasal cannula
  3. Venturi mask Correct answer.
  4. Partial rebreather mask

Explanation

A Venturi mask uses an air-entrainment jet that mixes oxygen with room air at a fixed ratio, giving a predictable FiO2. Variable-performance devices depend on the patient's inspiratory flow and minute ventilation.

Question 6Airway Management, Ventilation, and Oxygenation

A patient has a suspected cervical spine injury and requires airway opening. Which maneuver is most appropriate?

  1. Hyperextension of the neck
  2. Triple airway maneuver
  3. Jaw-thrust without head extension Correct answer.
  4. Head-tilt chin-lift

Explanation

The jaw-thrust maneuver opens the airway while maintaining inline stabilization of the cervical spine. Head-tilt and neck hyperextension risk worsening a spinal injury.

Question 7Airway Management, Ventilation, and Oxygenation

An adult with no signs of trauma is being ventilated with a bag-valve-mask. What is the recommended initial squeeze volume and rate?

  1. About 1000 mL every 3 seconds
  2. About 250 mL every 2 seconds
  3. About 800 mL every 2 seconds
  4. About 500 to 600 mL every 5 to 6 seconds Correct answer.

Explanation

Adult bag-valve-mask ventilation should deliver roughly 500 to 600 mL, enough to produce visible chest rise, about every 5 to 6 seconds. Excessive volume and rate raise intrathoracic pressure and reduce venous return.

Question 8Airway Management, Ventilation, and Oxygenation

Which condition is an absolute contraindication to the use of a supraglottic airway device?

  1. Copious airway secretions
  2. Known esophageal varices
  3. Gag reflex present Correct answer.
  4. Morbid obesity

Explanation

A supraglottic airway requires an absent gag reflex, so a patient who is awake and gagging is not a candidate. Secretions and obesity raise aspiration risk but are relative rather than absolute contraindications.

Question 9Airway Management, Ventilation, and Oxygenation

What is the primary purpose of preoxygenation before advanced airway placement?

  1. To reduce gastric distension
  2. To decrease carbon dioxide levels rapidly
  3. To suppress the gag reflex
  4. To increase oxygen reserves and delay desaturation during apnea Correct answer.

Explanation

Preoxygenation replaces nitrogen in the functional residual capacity with oxygen, creating a reservoir that prolongs safe apnea time. It does not anesthetize the airway or meaningfully change CO2 in the short term.

Question 10Airway Management, Ventilation, and Oxygenation

A trauma patient's oxygen saturation is 88% on a non-rebreather mask at 15 L/min. What is the most appropriate next action?

  1. Continue the current device and reassess in ten minutes
  2. Apply a simple face mask at 6 L/min
  3. Switch to a nasal cannula at 4 L/min
  4. Begin bag-valve-mask ventilation with supplemental oxygen Correct answer.

Explanation

Persistent hypoxemia despite a high-flow oxygen device indicates inadequate ventilation or oxygenation and warrants assisted ventilation with a bag-valve-mask. Lowering the oxygen delivery would worsen the hypoxemia.

Question 11Airway Management, Ventilation, and Oxygenation

Which statement about the oxyhemoglobin dissociation curve is correct?

  1. Hypothermia shifts the curve to the right
  2. A leftward shift decreases hemoglobin oxygen affinity
  3. Alkalosis shifts the curve to the right
  4. A rightward shift releases oxygen more readily to tissues Correct answer.

Explanation

A rightward shift reduces hemoglobin's affinity for oxygen, enhancing unloading at the tissues. This occurs with acidosis, hypercapnia, hyperthermia, and increased 2,3-DPG.

Question 12Airway Management, Ventilation, and Oxygenation

A patient in respiratory failure has an SpO2 of 92% with a respiratory rate of 8 and shallow depth. What is the most important intervention?

  1. Increase supplemental oxygen flow
  2. Begin assisted ventilation with a bag-valve-mask Correct answer.
  3. Encourage the patient to take deep breaths
  4. Place the patient in the recovery position

Explanation

Bradypnea with shallow breathing signals inadequate minute ventilation, and oxygenation alone does not correct hypercapnia. Assisted ventilation supports both oxygen delivery and carbon dioxide removal.

Question 13Airway Management, Ventilation, and Oxygenation

Which finding indicates a correctly placed endotracheal tube?

  1. Bilateral breath sounds with continuous waveform capnography Correct answer.
  2. Absent epigastric sounds with a single-use colorimetric detector that stays purple
  3. Vocalization after placement
  4. Chest rise only on the right side

Explanation

Bilateral breath sounds plus continuous waveform capnography confirming sustained CO2 production is the standard for verifying endotracheal placement. Colorimetric devices must change color with each breath.

Question 14Airway Management, Ventilation, and Oxygenation

What is the recommended suction duration for an adult during tracheal suctioning?

  1. 30 to 45 seconds
  2. 60 seconds
  3. As long as needed to clear secretions
  4. No more than 10 to 15 seconds Correct answer.

Explanation

Suction should be limited to about 10 to 15 seconds to reduce hypoxemia and vagal stimulation. Prolonged suctioning removes oxygen and can cause bradycardia.

Question 15Airway Management, Ventilation, and Oxygenation

When performing bag-valve-mask ventilation as a single rescuer, which technique best improves the seal?

  1. Resting the mask loosely on the face
  2. Using the E-C clamp technique with a two-handed grip when possible Correct answer.
  3. Ventilating as fast as possible to compensate for leaks
  4. Using the thenar eminence to press the mask

Explanation

The E-C clamp technique with the thumb and index finger forming a C around the mask and the remaining fingers lifting the jaw improves the seal. Two-rescuer ventilation with a two-handed mask grip is even more effective.

Question 16Airway Management, Ventilation, and Oxygenation

Which patient is most likely to benefit from noninvasive positive-pressure ventilation?

  1. A patient who is apneic
  2. A patient with an unprotected airway and vomiting
  3. A patient with an acute exacerbation of COPD and respiratory acidosis Correct answer.
  4. A patient with a facial injury and unstable midface

Explanation

Noninvasive positive-pressure ventilation is well supported for COPD exacerbations with respiratory acidosis in a cooperative patient with a protected airway. Apnea, unprotected airway, and facial trauma are contraindications.

Question 17Airway Management, Ventilation, and Oxygenation

A patient has a foreign body airway obstruction and is still able to cough forcefully. What is the appropriate action?

  1. Encourage forceful coughing and monitor Correct answer.
  2. Perform a blind finger sweep
  3. Begin back blows
  4. Perform abdominal thrusts immediately

Explanation

With effective coughing, the patient is moving air and should be encouraged to clear the object spontaneously while being monitored. Interventions such as thrusts are reserved for ineffective cough or worsening obstruction.

Question 18Airway Management, Ventilation, and Oxygenation

Which statement accurately describes the relationship between oxygen flow and FiO2 with a nasal cannula?

  1. FiO2 increases predictably by 10% for every liter per minute
  2. FiO2 is fixed at 24% regardless of flow
  3. FiO2 is variable and depends on inspiratory flow and breathing pattern Correct answer.
  4. FiO2 reaches 100% at 6 L/min

Explanation

A nasal cannula is a variable-performance device, so the actual FiO2 depends on the patient's inspiratory flow, mouth breathing, and respiratory pattern. Nomograms give only rough estimates.

Question 19Airway Management, Ventilation, and Oxygenation

A patient with a suspected opioid overdose has a respiratory rate of 4 and an SpO2 of 78%. What is the priority sequence?

  1. Open the airway, provide bag-valve-mask ventilation with oxygen, and administer naloxone Correct answer.
  2. Administer naloxone and wait for the respiratory rate to improve before supporting ventilation
  3. Place the patient in the recovery position and reassess
  4. Apply a nasal cannula and monitor

Explanation

Airway and breathing take priority, so ventilation and oxygenation must be supported immediately while naloxone is given. Waiting for the antidote to reverse hypoventilation delays correction of hypoxemia.

Question 20Airway Management, Ventilation, and Oxygenation

Which statement about the Sellick maneuver (cricoid pressure) during bag-valve-mask ventilation is most accurate?

  1. It may worsen ventilation and is no longer routinely recommended Correct answer.
  2. It reliably prevents aspiration and should always be applied
  3. It improves the mask seal in all patients
  4. It should be applied only after the tube is secured

Explanation

Cricoid pressure can impede ventilation, worsen the view during intubation, and does not reliably prevent aspiration, so routine use has been abandoned. It may be used selectively in some rapid-sequence protocols.

Question 21Airway Management, Ventilation, and Oxygenation

A patient with severe asthma has an SpO2 of 89% and increasing fatigue. Which intervention is most appropriate?

  1. High-flow oxygen with assisted ventilation if fatigue progresses Correct answer.
  2. Sedation to reduce work of breathing
  3. Low-flow oxygen to target an SpO2 of 88 to 92%
  4. A non-rebreather mask alone with no reassessment

Explanation

Severe asthma with hypoxemia and fatigue requires high-flow oxygen and preparation for assisted ventilation as the patient tires. Sedation can depress respiratory drive and should be avoided.

Question 22Airway Management, Ventilation, and Oxygenation

Which statement about gastric insufflation during bag-valve-mask ventilation is correct?

  1. It is prevented by higher ventilation rates
  2. It is reduced by delivering larger tidal volumes rapidly
  3. It occurs when airway pressures exceed the esophageal opening pressure and increases aspiration risk Correct answer.
  4. It has no effect on ventilation

Explanation

When peak airway pressure exceeds the esophageal opening pressure, gas enters the stomach, raising the risk of regurgitation and aspiration. Delivering smaller volumes over about one second and avoiding excessive rates reduces this risk.

Question 23Airway Management, Ventilation, and Oxygenation

Which statement about pulse oximetry is correct?

  1. It detects hypercapnia before hypoxemia
  2. It is unreliable in the presence of poor perfusion, motion, or carbon monoxide poisoning Correct answer.
  3. It remains accurate with severe anemia
  4. It directly measures arterial oxygen tension

Explanation

Pulse oximetry estimates hemoglobin oxygen saturation and is affected by poor perfusion, motion artifact, and dyshemoglobins such as carboxyhemoglobin. It does not measure PaO2 or CO2.

Question 24Airway Management, Ventilation, and Oxygenation

What is the recommended oxygen flow rate for a simple face mask?

  1. 6 to 10 L/min Correct answer.
  2. 1 to 2 L/min
  3. 15 L/min
  4. 2 to 4 L/min

Explanation

A simple face mask should be run at 6 to 10 L/min to deliver roughly 40 to 60% oxygen and to prevent rebreathing of exhaled CO2. Lower flows allow CO2 accumulation in the mask.

Question 25Airway Management, Ventilation, and Oxygenation

Which sign most specifically indicates complete upper airway obstruction in a conscious adult?

  1. Inability to speak or cough with clutching the throat Correct answer.
  2. Forceful coughing
  3. Inspiratory stridor
  4. Wheezing on exhalation

Explanation

Inability to speak or cough, often with the universal choking sign, indicates complete obstruction with no air movement. Forceful coughing and stridor indicate partial obstruction.

Question 26Airway Management, Ventilation, and Oxygenation

Which structure is the narrowest portion of the adult upper airway and a common site of obstruction in an unresponsive patient?

  1. The oropharynx
  2. The nasopharynx
  3. The trachea
  4. The glottic opening Correct answer.

Explanation

In adults the glottic opening is the narrowest point of the upper airway, and loss of muscle tone allows the tongue and epiglottis to obstruct at the laryngeal inlet. Recognizing this helps the rescuer target positioning and airway adjuncts appropriately.

Question 27Airway Management, Ventilation, and Oxygenation

An adult cardiac arrest patient is being ventilated with a bag-valve-mask using room air. Which change most increases the delivered oxygen concentration without changing the device?

  1. Increasing the ventilation rate to 20 per minute
  2. Attaching an oxygen reservoir and running oxygen at 10 to 15 L/min Correct answer.
  3. Squeezing the bag more forcefully with each breath
  4. Adding a nasal cannula under the mask at 2 L/min

Explanation

A bag-valve-mask delivers roughly 21% oxygen from room air, but adding a reservoir with high-flow oxygen raises the delivered fraction to near 100%. Squeeze force and rate affect volume and minute ventilation, not the inspired oxygen fraction.

Question 28Airway Management, Ventilation, and Oxygenation

A patient is being ventilated through a supraglottic airway and the capnography waveform suddenly becomes flat while the chest stops rising. Which cause should be suspected first?

  1. Development of a pneumothorax
  2. Hyperoxia from excessive oxygen flow
  3. Mild sedation from a recent analgesic dose
  4. Dislodgement or obstruction of the airway device Correct answer.

Explanation

A sudden loss of waveform with absent chest rise points to a problem at the device or airway interface, such as dislodgement, migration, or obstruction. Airway device position should be assessed and corrected before other causes are pursued.

Question 29Airway Management, Ventilation, and Oxygenation

A spontaneously breathing adult with an SpO2 of 90% needs high-concentration oxygen but cannot tolerate a tight-sealing mask. Which device delivers the highest inspired oxygen among the following while allowing the patient to breathe spontaneously?

  1. Venturi mask at 28%
  2. Simple face mask at 6 L/min
  3. Non-rebreather mask at 15 L/min Correct answer.
  4. Nasal cannula at 4 L/min

Explanation

A non-rebreather mask with a reservoir and a high flow rate delivers the highest oxygen fraction of the listed devices, approaching 90% or more. It is suitable for a spontaneously breathing patient who cannot tolerate a tight seal.

Question 30Airway Management, Ventilation, and Oxygenation

A patient with a tracheostomy is receiving suctioning and the catheter meets resistance with no return of secretions. Which action is most appropriate?

  1. Instill several milliliters of saline and suction continuously
  2. Force the catheter further while applying continuous suction
  3. Increase suction pressure to the maximum and hold the catheter in place
  4. Withdraw slightly, apply intermittent suction, and reassess the patient Correct answer.

Explanation

Resistance with no return suggests the catheter is against the airway wall or a mucous plug; withdrawing slightly and using intermittent suction avoids mucosal injury while clearing secretions. Forcing the catheter or applying continuous high suction risks trauma, hypoxia, and atelectasis.

Question 31Patient Assessment and Clinical Decision Making

A trauma patient arrives with a patent airway, spontaneous breathing, and a weak, rapid radial pulse. Which component of the primary assessment is the most appropriate next priority?

  1. Splinting of suspected extremity fractures
  2. Circulation and control of major bleeding Correct answer.
  3. Obtaining a full medical history from the family
  4. Detailed head-to-toe secondary survey

Explanation

The primary assessment follows a fixed sequence in which life threats are addressed in order: airway, breathing, circulation, disability, exposure. A weak, rapid pulse signals possible shock, so circulation and hemorrhage control must be assessed and managed before any secondary survey or history taking.

Question 32Patient Assessment and Clinical Decision Making

Which finding is the earliest and most reliable indicator of inadequate ventilation during a patient assessment?

  1. Cyanosis of the nail beds
  2. Increasing respiratory rate with shallow depth Correct answer.
  3. A rising blood pressure reading
  4. Absent breath sounds on auscultation

Explanation

Tachypnea with shallow tidal volume reflects a compensatory attempt to maintain minute ventilation and appears before oxygenation visibly fails. Cyanosis is a late and unreliable sign, and absent breath sounds indicate a severe but later-stage finding.

Question 33Patient Assessment and Clinical Decision Making

During the assessment of an adult with a suspected opioid overdose, the patient has a respiratory rate of 6 per minute and pinpoint pupils. Which action is the priority?

  1. Placing the patient in the recovery position and observing
  2. Providing bag-mask ventilation and administering naloxone Correct answer.
  3. Establishing a definitive airway with intubation
  4. Obtaining a 12-lead ECG before any intervention

Explanation

In opioid-associated respiratory depression, the immediate priorities are supporting ventilation and administering an opioid antagonist. Ventilation comes before pharmacologic reversal because hypoventilation is the immediate threat to life.

Question 34Patient Assessment and Clinical Decision Making

A patient with a suspected stroke has a blood glucose of 3.1 mmol/L. What is the most appropriate interpretation of this finding?

  1. Hypoglycemia is a stroke mimic and must be corrected before stroke pathways proceed Correct answer.
  2. The glucose should be rechecked only after CT imaging
  3. The glucose value is unrelated to neurologic symptoms
  4. The low glucose confirms an ischemic stroke diagnosis

Explanation

Hypoglycemia can produce focal neurologic deficits that closely mimic stroke, so it must be identified and corrected as part of the initial assessment. Treating the glucose first prevents misdirected stroke interventions and may resolve the deficits.

Question 35Patient Assessment and Clinical Decision Making

Which finding best distinguishes an absent or agonal respiratory pattern during the initial assessment?

  1. Irregular gasping with no effective tidal volume Correct answer.
  2. Breathing that increases with painful stimulus
  3. Regular breathing at 22 breaths per minute
  4. Deep, rapid breathing with a fruity odor

Explanation

Agonal respirations are irregular, gasping efforts that do not produce effective ventilation and indicate a peri-arrest state. They require immediate airway and ventilatory support rather than observation.

Question 36Patient Assessment and Clinical Decision Making

A patient reports crushing chest pain radiating to the left arm with diaphoresis. Which assessment step should be completed before obtaining a detailed past medical history?

  1. Reviewing the medication list with a family member
  2. Documenting the family cardiac history
  3. Recording the patient's surgical history
  4. Obtaining and interpreting a 12-lead ECG Correct answer.

Explanation

For suspected acute coronary syndrome, the 12-lead ECG is a time-critical diagnostic step that guides immediate treatment and transport decisions. Detailed history elements can be gathered afterward without delaying reperfusion timelines.

Question 37Patient Assessment and Clinical Decision Making

A trauma patient has a systolic blood pressure of 88 mmHg, a heart rate of 126, and cool, clammy skin. Which classification best describes these findings?

  1. Neurogenic shock with bradycardia
  2. Decompensated hemorrhagic shock Correct answer.
  3. Compensated shock with normal perfusion
  4. Septic shock with warm extremities

Explanation

Hypotension with marked tachycardia and cool, clammy skin indicates that compensatory mechanisms have failed, consistent with decompensated hemorrhagic shock. Compensated shock typically maintains a normal blood pressure.

Question 38Patient Assessment and Clinical Decision Making

Which assessment finding is most consistent with tension pneumothorax in a spontaneously breathing patient?

  1. Tracheal deviation toward the affected side
  2. Unilateral absent breath sounds with distended neck veins Correct answer.
  3. Bilateral crackles with a productive cough
  4. Hyperresonance with improved breath sounds on inspiration

Explanation

Tension pneumothorax produces unilateral absent breath sounds, severe respiratory distress, and signs of obstructive shock such as distended neck veins. Tracheal deviation, when present, shifts away from the affected side and is a late finding.

Question 39Patient Assessment and Clinical Decision Making

A patient is confused, has a blood glucose of 2.8 mmol/L, and is able to swallow safely. What is the most appropriate initial management?

  1. Withhold glucose until intravenous access is obtained
  2. Administer oral glucose and reassess Correct answer.
  3. Place the patient in a supine position and monitor
  4. Administer naloxone to reverse the confusion

Explanation

When a hypoglycemic patient can protect the airway and swallow, oral glucose is a rapid and appropriate first intervention. Reassessment confirms response and guides further treatment.

Question 40Patient Assessment and Clinical Decision Making

During assessment of an unresponsive patient, which maneuver is most appropriate to open the airway when a cervical spine injury is suspected?

  1. Jaw thrust without head extension Correct answer.
  2. Hyperextension of the neck
  3. Placement in the prone position
  4. Head-tilt, chin-lift

Explanation

The jaw thrust opens the airway while minimizing movement of the cervical spine, making it the preferred maneuver when spinal injury is suspected. The head-tilt, chin-lift can produce cervical movement and is avoided in that setting.

Question 41Patient Assessment and Clinical Decision Making

A patient with a history of asthma presents with severe dyspnea, a silent chest on auscultation, and a decreasing respiratory rate. What does the silent chest most likely indicate?

  1. Resolution of the asthma exacerbation
  2. Development of a pneumothorax only
  3. Impending respiratory failure from minimal air movement Correct answer.
  4. Improvement in bronchospasm

Explanation

A silent chest in severe asthma indicates critically reduced airflow and impending respiratory failure rather than improvement. It is an ominous sign requiring immediate ventilatory support and transport.

Question 42Patient Assessment and Clinical Decision Making

Which set of vital signs is most concerning for a patient in the early compensated phase of shock?

  1. Blood pressure 118/76, heart rate 92, respiratory rate 18
  2. Blood pressure 122/80, heart rate 108, respiratory rate 20, cool skin Correct answer.
  3. Blood pressure 90/60, heart rate 58, respiratory rate 14
  4. Blood pressure 140/90, heart rate 70, respiratory rate 16

Explanation

Early compensated shock often presents with a rising heart rate, mild tachypnea, and cutaneous signs such as cool skin while blood pressure is still maintained. Recognizing these subtle changes allows earlier intervention.

Question 43Patient Assessment and Clinical Decision Making

A patient has a Glasgow Coma Scale score of 9. What is the most appropriate interpretation?

  1. Normal neurologic status
  2. Mild head injury with low risk of deterioration
  3. Severe injury with no need for airway planning
  4. Moderate head injury requiring close monitoring and airway readiness Correct answer.

Explanation

A GCS of 9 falls in the moderate range (9 to 12) and indicates a significant head injury with risk of deterioration. Such patients require close monitoring and preparation for airway management.

Question 44Patient Assessment and Clinical Decision Making

Which finding during the secondary survey most strongly suggests a pelvic fracture in a trauma patient?

  1. Pain on palpation of the lateral thigh
  2. Instability and pain with gentle compression of the iliac crests Correct answer.
  3. Localized tenderness over the lumbar spine
  4. Bilateral equal femoral pulses

Explanation

Pain or instability with gentle compression of the pelvis suggests a pelvic ring injury and possible significant hemorrhage. The examination should be performed gently and only once to avoid disrupting clots.

Question 45Patient Assessment and Clinical Decision Making

A patient with a suspected abdominal aortic aneurysm reports sudden severe back pain and has a pulsatile abdominal mass. What is the most appropriate assessment conclusion?

  1. The mass is likely benign and observation is appropriate
  2. The patient should be given oral fluids and reassessed in one hour
  3. The findings are consistent with a surgical emergency requiring rapid transport Correct answer.
  4. The pain is most likely musculoskeletal in origin

Explanation

Sudden severe back pain with a pulsatile abdominal mass suggests a leaking or ruptured aortic aneurysm, a life-threatening surgical emergency. Rapid transport with hemodynamic support is the priority.

Question 46Patient Assessment and Clinical Decision Making

Which assessment parameter is most useful for detecting early deterioration in a patient with a suspected internal hemorrhage?

  1. Assessment of pupil size
  2. Measurement of body temperature
  3. A single blood pressure reading
  4. Serial measurement of heart rate and mental status Correct answer.

Explanation

Trending heart rate and mental status detects compensatory responses to blood loss before blood pressure falls. A single blood pressure reading may appear normal despite significant hemorrhage.

Question 47Patient Assessment and Clinical Decision Making

A patient is found with a decreased level of consciousness and a strong odor of alcohol. What is the most appropriate assessment approach?

  1. Attribute all findings to intoxication and monitor only
  2. Delay assessment until the patient becomes sober
  3. Perform a complete assessment and consider other causes of altered mental status Correct answer.
  4. Assume the decreased consciousness is solely due to alcohol

Explanation

Alcohol intoxication does not exclude other causes of altered mental status such as hypoglycemia, head injury, or overdose. A complete assessment with objective findings is required to identify treatable causes.

Question 48Patient Assessment and Clinical Decision Making

Which finding best indicates that a patient has an adequate airway during the initial assessment?

  1. Audible stridor at rest
  2. Gurgling sounds with inspiration
  3. Clear speech in a normal voice Correct answer.
  4. Paradoxical chest movement

Explanation

Clear, normal speech demonstrates that air is moving through the upper airway and vocal cords without obstruction. Stridor and gurgling indicate partial obstruction, and paradoxical movement reflects a breathing problem.

Question 49Patient Assessment and Clinical Decision Making

A patient's pain is described as tearing and radiates between the shoulder blades. Which assessment consideration is most important?

  1. The pain is likely musculoskeletal and can be managed with reassurance
  2. The pain suggests a lower extremity injury
  3. Tearing interscapular pain raises concern for aortic dissection Correct answer.
  4. The pain pattern indicates simple indigestion

Explanation

Tearing pain radiating between the shoulder blades is a classic description of aortic dissection, a vascular emergency. Rapid recognition and transport are essential because delay increases mortality.

Question 50Patient Assessment and Clinical Decision Making

What is the primary purpose of obtaining a SAMPLE history?

  1. To gather subjective information about symptoms, allergies, medications, and events Correct answer.
  2. To confirm a diagnosis before transport
  3. To determine the patient's insurance status
  4. To replace the primary assessment

Explanation

SAMPLE history collects subjective information including symptoms, allergies, medications, past history, last oral intake, and events leading to the illness. It complements, but does not replace, the primary assessment.
