Q21The most important action a nurse can perform to prevent healthcare-associated infections is:
✓ Correct answer: A. Hand hygiene before and after patient contact
Hand hygiene (with soap and water or alcohol-based rub) is the single most effective measure to prevent transmission of healthcare-associated pathogens, as per WHO and CDC guidelines.
Q22A client post-coronary artery bypass graft (CABG) has mediastinal chest tubes. The nurse notes 200 mL of bloody drainage in the first 30 minutes. The nurse should:
✓ Correct answer: B. Notify the surgeon immediately
Normal post-CABG drainage is approximately 100 mL/hr. Output of 200 mL in 30 minutes (400 mL/hr equivalent) suggests hemorrhage and requires immediate surgical notification.
Q23A 6-month-old is brought to the clinic for routine vaccinations. Which vaccine is NOT given at this visit per the standard immunisation schedule?
✓ Correct answer: B. MMR (measles, mumps, rubella)
MMR vaccine is given at 12–15 months (first dose). At 6 months, DTaP, IPV, Hib, PCV13, and rotavirus vaccines are typically administered.
Q24Which position is most appropriate for a client experiencing an acute asthma attack?
✓ Correct answer: B. High Fowler's (90°)
High Fowler's position maximizes lung expansion by reducing pressure of abdominal contents on the diaphragm, easing breathing during an asthma attack.
Q25A nurse is caring for a client following a modified radical mastectomy. Which arm should NOT be used for blood pressure measurement, IV insertion, or venipuncture?
✓ Correct answer: B. The operative arm (ipsilateral)
The arm on the same side as the mastectomy should not be used for blood pressure, IV access, or blood draws due to risk of lymphedema from lymph node removal.
Q26A DHA-regulated hospital implements a 'no harm' reporting system for near-miss events. The nurse's role in this system is:
✓ Correct answer: B. Report all near-misses, incidents, and adverse events without fear of punitive action — to improve system safety
DHA promotes a just culture of safety reporting. Near-miss reporting is essential for identifying systemic vulnerabilities. Nurses are encouraged to report without fear of punishment to drive quality improvement.
Q27A client receiving IV aminoglycosides is at risk for which toxicities that require monitoring?
✓ Correct answer: B. Nephrotoxicity and ototoxicity
Aminoglycosides (gentamicin, tobramycin, amikacin) cause nephrotoxicity and ototoxicity (hearing loss, vestibular toxicity). Monitor creatinine, urine output, and serum drug levels.
Q28When should the nurse apply contact precautions for a patient with MRSA wound infection?
✓ Correct answer: D. For all care activities that involve contact with the patient or their environment
Contact precautions (gown and gloves) must be used for ALL interactions with an MRSA patient or their immediate environment, not only during wound care.
Q29A patient with hypothyroidism (myxedema) is receiving levothyroxine. Which adverse effect requires immediate reporting?
✓ Correct answer: C. Chest pain and palpitations
Chest pain and palpitations indicate that the levothyroxine dose may be too high, causing thyroid hormone excess and cardiac effects (angina, tachycardia, atrial fibrillation). This requires immediate dose reassessment.
Q30A child with croup is brought to the emergency department with a barking cough and moderate respiratory distress. Initial management includes:
✓ Correct answer: B. Nebulized epinephrine and dexamethasone
Croup (laryngotracheobronchitis, usually viral) with moderate distress is treated with racemic epinephrine (nebulized) for acute bronchodilation and oral/IM dexamethasone to reduce subglottic inflammation.
