Patient Care and Clinical Procedures

  • Normal adult resting vital signs: oral temperature 36.5–37.5 °C (97.7–99.5 °F), pulse 60–100 beats/min, respirations 12–20 breaths/min, blood pressure <120/80 mmHg, SpO2 ≥95% on room air.

  • Orthostatic hypotension is a drop of ≥20 mmHg systolic or ≥10 mmHg diastolic within 3 minutes of standing from supine.

  • The 5 rights of medication administration are right patient, right drug, right dose, right route, and right time.

  • Standard precautions apply to all patients regardless of diagnosis; hand hygiene is performed before and after every patient contact.

  • When transferring a patient, keep the bed at the lowest position, lock wheels, and raise the side rail on the opposite side before moving the patient.

  • The head of bed should be elevated 30–45 degrees for patients receiving enteral tube feedings to reduce aspiration risk.

  • A patient in restraints requires reassessment at least every 15 minutes for circulation, skin integrity, and safety, with release and range-of-motion at least every 2 hours.

  • The Glasgow Coma Scale score ranges from 3 (deep coma) to 15 (fully alert); a score ≤8 indicates severe impairment and possible need for airway protection.

Anatomy

  • Anatomical position is standing upright, face forward, arms at the sides with palms facing forward, and feet flat on the floor.

  • The four primary tissue types are epithelial, connective, muscle, and nervous tissue.

  • The axial skeleton has 80 bones (skull, vertebral column, rib cage); the appendicular skeleton has 126 bones (limbs and girdles).

  • There are 206 bones in the adult human skeleton; an infant is born with about 270 bones that fuse during development.

  • The heart has four chambers: right atrium, right ventricle, left atrium, and left ventricle; the left ventricle has the thickest myocardium because it pumps to the systemic circulation.

  • The respiratory tract is divided into upper (nose, pharynx, larynx) and lower (trachea, bronchi, bronchioles, alveoli) portions; gas exchange occurs in the alveoli.

  • The nephron is the functional unit of the kidney, consisting of the glomerulus, Bowman's capsule, and renal tubules.

  • Cranial nerves I–XII: olfactory, optic, oculomotor, trochlear, trigeminal, abducens, facial, vestibulocochlear, glossopharyngeal, vagus, accessory, hypoglossal.

Physiology and Pathophysiology

  • Cardiac output = heart rate × stroke volume; normal resting cardiac output is about 4–8 L/min.

  • Mean arterial pressure (MAP) ≈ diastolic pressure + one-third of the pulse pressure; a MAP ≥65 mmHg is generally needed for adequate organ perfusion.

  • Normal pH of arterial blood is 7.35–7.45; below 7.35 is acidosis and above 7.45 is alkalosis.

  • The renin-angiotensin-aldosterone system raises blood pressure by causing vasoconstriction and sodium/water retention.

  • Insulin lowers blood glucose by promoting cellular uptake; glucagon raises blood glucose by stimulating glycogenolysis and gluconeogenesis.

  • Inflammation is characterized by redness, heat, swelling, pain, and loss of function (rubor, calor, tumor, dolor, functio laesa).

  • Edema results from increased capillary hydrostatic pressure, decreased plasma oncotic pressure, increased capillary permeability, or lymphatic obstruction.

  • Shock is inadequate tissue perfusion; types include hypovolemic, cardiogenic, distributive (septic, anaphylactic, neurogenic), and obstructive.

Infection Prevention and Control

  • The chain of infection has six links: infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host.

  • Hand hygiene with soap and water for at least 20 seconds is required when hands are visibly soiled or after contact with spore-forming organisms such as Clostridioides difficile.

  • Alcohol-based hand rub is preferred for routine hand hygiene when hands are not visibly soiled; apply enough product to cover all surfaces and rub until dry (about 20–30 seconds).

  • Personal protective equipment is removed in this order: gloves, goggles/face shield, gown, then mask/respirator; hand hygiene follows.

  • A surgical mask is worn for droplet precautions; an N95 or higher respirator is worn for airborne precautions (e.g., tuberculosis, measles, varicella).

  • Standard precautions apply to blood, all body fluids, secretions, excretions (except sweat), nonintact skin, and mucous membranes.

  • Transmission-based precautions: contact (e.g., MRSA, C. difficile), droplet (e.g., influenza, pertussis), airborne (e.g., TB, measles, varicella).

  • Sterile technique requires that sterile items contact only sterile items; a sterile field is considered contaminated if touched by a nonsterile object or if it becomes wet.

Medical Terminology and Documentation

  • Common prefixes: brady- (slow), tachy- (fast), hyper- (above), hypo- (below), dys- (difficult/painful), poly- (many), a-/an- (without).

  • Common suffixes: -itis (inflammation), -ectomy (surgical removal), -ostomy (creating an opening), -otomy (incision), -algia (pain), -emia (blood condition), -uria (urine condition).

  • Root words identify the body part or system: cardi- (heart), nephr- (kidney), hepat- (liver), pulmon- (lung), gastr- (stomach), neur- (nerve).

  • The SOAP note format is Subjective, Objective, Assessment, Plan.

  • Documentation must be accurate, timely, complete, legible, and objective; late entries are labeled as such and never backdated.

  • Abbreviations to avoid in documentation include U (unit), IU (international unit), QD and QOD (daily/every other day), and trailing zeros (write 5 mg, not 5.0 mg).

  • HIPAA permits disclosure of protected health information for treatment, payment, and health care operations without patient authorization.

  • The medical record is a legal document; errors are corrected with a single line, the correction, initials, and date, never by erasure or correction fluid.

Pharmacology and Medication Safety

  • Therapeutic index = toxic dose / therapeutic dose; a narrow therapeutic index (e.g., warfarin, digoxin, lithium) requires close monitoring.

  • The six rights of medication administration: right patient, right drug, right dose, right route, right time, and right documentation.

  • Oral medications are absorbed primarily in the small intestine; first-pass metabolism in the liver reduces bioavailability of orally administered drugs.

  • Common antidotes: naloxone for opioids, flumazenil for benzodiazepines, acetylcysteine for acetaminophen, vitamin K for warfarin, protamine sulfate for heparin.

  • High-alert medications include insulin, heparin, opioids, and concentrated electrolytes; they require independent double-checks.

  • Never administer a medication prepared by another person; label all syringes and containers immediately after preparation.

  • Adverse drug reactions are classified as predictable (Type A, dose-dependent) or unpredictable (Type B, idiosyncratic or allergic).

  • Pregnancy risk categories have been replaced by the Pregnancy and Lactation Labeling Rule (PLLR), which uses narrative sections rather than letter grades.

Laboratory and Diagnostic Testing

  • Normal adult hemoglobin: men 13.5–17.5 g/dL, women 12.0–15.5 g/dL; hematocrit is roughly three times the hemoglobin value.

  • Normal adult white blood cell count is 4,500–11,000 cells/µL; neutrophils are the most abundant leukocyte.

  • Normal adult platelet count is 150,000–450,000/µL; thrombocytopenia increases bleeding risk.

  • Normal fasting blood glucose is 70–99 mg/dL; a fasting glucose ≥126 mg/dL on two occasions supports a diabetes diagnosis.

  • Normal adult serum potassium is 3.5–5.0 mEq/L; values outside this range can cause cardiac dysrhythmias.

  • Normal adult serum sodium is 135–145 mEq/L; normal serum calcium is 8.5–10.5 mg/dL.

  • A urinalysis positive for nitrites and leukocyte esterase suggests a urinary tract infection.

  • Therapeutic drug monitoring for vancomycin measures trough levels, typically drawn within 30 minutes before the next dose.

Professional Ethics, Law, and Scope of Practice

  • Autonomy respects the patient's right to make decisions; beneficence is acting in the patient's best interest; nonmaleficence is doing no harm; justice is fair treatment.

  • Informed consent requires capacity, voluntary decision-making, and disclosure of risks, benefits, and alternatives.

  • A living will states a patient's wishes about life-sustaining treatment; a durable power of attorney for health care designates a surrogate decision-maker.

  • Mandatory reporting includes suspected child abuse, elder abuse, and certain communicable diseases, as defined by state law.

  • Scope of practice defines the procedures and responsibilities a health care worker is legally permitted to perform under state licensure and employer policy.

  • A health care worker who observes an error must report it through the facility's incident reporting system; incident reports are not placed in the medical record.

  • Confidentiality is breached only when disclosure is required by law (e.g., reportable disease, court order) or necessary to prevent serious harm.

  • Negligence requires duty, breach of duty, causation, and damages; malpractice is professional negligence.

Health and Safety

  • The Occupational Safety and Health Administration (OSHA) Bloodborne Pathogens Standard requires an exposure control plan, hepatitis B vaccination offer, and post-exposure evaluation.

  • Needles and sharps are placed in puncture-resistant, closable, leak-proof containers immediately after use; never recap by hand.

  • Safe patient handling programs use mechanical lifts and assistive devices to reduce musculoskeletal injuries from manual lifting.

  • Fire safety uses the RACE mnemonic: Rescue, Alarm, Contain, Extinguish/Evacuate.

  • The PASS technique for a fire extinguisher: Pull the pin, Aim at the base of the fire, Squeeze the handle, Sweep side to side.

  • A safety data sheet (SDS) provides hazard, handling, and first-aid information for every hazardous chemical in the workplace.

  • Wet floors require warning signs; spills are cleaned immediately to prevent falls.

  • Latex allergy precautions include using nonlatex gloves and avoiding latex-containing supplies for sensitized patients and staff.

Quick reference

Emergency Response

  • The adult chain of survival: recognize and activate emergency response, early CPR, rapid defibrillation, advanced life support, and post-cardiac arrest care.

  • Adult CPR compression rate is 100–120 compressions per minute at a depth of at least 2 inches (5 cm) but not more than 2.4 inches (6 cm).

  • The compression-to-ventilation ratio for single-rescuer adult CPR is 30:2; for two-rescuer infant and child CPR, it is 15:2.

  • Defibrillation should be delivered as soon as an AED is available; resume compressions immediately after the shock.

  • Anaphylaxis is treated with intramuscular epinephrine (adult dose 0.3–0.5 mg of 1:1,000 solution) into the anterolateral thigh.

  • Signs of stroke can be remembered with BE-FAST: Balance, Eyes, Face drooping, Arm weakness, Speech difficulty, Time to call emergency services.

  • Hypoglycemia in a conscious patient is treated with 15 g of fast-acting carbohydrate, rechecked in 15 minutes (the 15-15 rule).

  • A choking adult who cannot speak or cough receives abdominal thrusts (Heimlich maneuver); an infant receives 5 back blows followed by 5 chest thrusts.

Communication and Interprofessional Practice

  • SBAR is a structured handoff tool: Situation, Background, Assessment, Recommendation.

  • Therapeutic communication uses open-ended questions, active listening, reflection, and clarification; it avoids false reassurance and why questions.

  • Teach-back confirms patient understanding by asking the patient to explain information in their own words.

  • Interprofessional collaboration requires role clarity, mutual respect, and shared decision-making among team members.

  • Conflict resolution uses 'I' statements, focuses on the problem rather than the person, and seeks a mutually acceptable solution.

  • Effective handoffs include the patient's current condition, recent changes, pending tests, and a clear plan of care.

  • Language barriers require a qualified medical interpreter; family members should not be used as interpreters for clinical discussions.

  • Documentation of communication includes the time, participants, content, and patient response to ensure continuity of care.
