1. Which of the following is the primary mechanism of action of ACE inhibitors?

A. Block calcium channels
B. Inhibit angiotensin II formation
C. Increase sodium retention
D. Stimulate beta receptors

🟢 Correct Answer: B. Inhibit angiotensin II formation

🔴 Explanation: ACE inhibitors prevent conversion of angiotensin I to angiotensin II, reducing
vasoconstriction and lowering blood pressure.



2. A patient presents with sudden chest pain and dyspnea. What is the priority assessment?

A. Blood glucose
B. Lung auscultation
C. Oxygen saturation
D. Temperature

🟢 Correct Answer: C. Oxygen saturation

🔴 Explanation: Oxygenation status is critical in suspected cardiopulmonary emergencies and
must be assessed immediately.



3. Which condition is characterized by insulin resistance?

,A. Type 1 diabetes
B. Type 2 diabetes
C. Diabetes insipidus
D. Gestational diabetes

🟢 Correct Answer: B. Type 2 diabetes

🔴 Explanation: Type 2 diabetes primarily involves insulin resistance with relative insulin
deficiency.



4. What is the most appropriate initial treatment for anaphylaxis?

A. Antihistamines
B. Corticosteroids
C. Epinephrine
D. Oxygen

🟢 Correct Answer: C. Epinephrine

🔴 Explanation: Epinephrine is the first-line treatment for anaphylaxis due to its rapid reversal
of airway and circulatory compromise.



5. Which lab value indicates renal impairment?

A. Low creatinine
B. Elevated BUN
C. Low sodium
D. High potassium only

🟢 Correct Answer: B. Elevated BUN

🔴 Explanation: Elevated blood urea nitrogen suggests decreased renal clearance and impaired
kidney function.



6. A patient with asthma should avoid which medication?

A. Acetaminophen
B. Beta-blockers
C. Antihistamines
D. Corticosteroids

,🟢 Correct Answer: B. Beta-blockers

🔴 Explanation: Beta-blockers can cause bronchoconstriction and worsen asthma symptoms.



7. What is the hallmark symptom of heart failure?

A. Fever
B. Edema
C. Rash
D. Hematuria

🟢 Correct Answer: B. Edema

🔴 Explanation: Fluid retention leading to edema is a key manifestation of heart failure.



8. Which electrolyte imbalance causes muscle weakness?

A. Hyperkalemia
B. Hypokalemia
C. Hypernatremia
D. Hypercalcemia

🟢 Correct Answer: B. Hypokalemia

🔴 Explanation: Low potassium disrupts muscle contraction, causing weakness and arrhythmias.



9. What is the first step in evidence-based practice?

A. Implement intervention
B. Evaluate outcomes
C. Ask a clinical question
D. Review literature

🟢 Correct Answer: C. Ask a clinical question

🔴 Explanation: Evidence-based practice begins with formulating a clear clinical question.



10. Which medication is used for acute angina relief?

, A. Lisinopril
B. Nitroglycerin
C. Metformin
D. Warfarin

🟢 Correct Answer: B. Nitroglycerin

🔴 Explanation: Nitroglycerin provides rapid vasodilation to relieve angina symptoms.



11. What is a key ethical principle in patient autonomy?

A. Beneficence
B. Justice
C. Respect for decisions
D. Nonmaleficence

🟢 Correct Answer: C. Respect for decisions

🔴 Explanation: Autonomy emphasizes respecting patients' rights to make informed decisions.



12. Which condition causes metabolic acidosis?

A. Vomiting
B. Diarrhea
C. Hyperventilation
D. Hypokalemia

🟢 Correct Answer: B. Diarrhea

🔴 Explanation: Diarrhea causes bicarbonate loss, leading to metabolic acidosis.



13. What is the normal range of adult heart rate?

A. 40–60 bpm
B. 60–100 bpm
C. 100–140 bpm
D. 120–160 bpm
