Questions with answers & rationales)
1. Which cranial nerve is responsible for facial sensation?
A. CN VII
B. CN V
C. CN IX
D. CN XII
Answer: B
Rationale: The trigeminal nerve (CN V) controls facial sensation and
motor functions like chewing.
2. Which heart sound is associated with atrial contraction?
A. S1
B. S2
C. S3
D. S4
Answer: D
Rationale: An S4 (atrial gallop) occurs when the atria contract to push
blood into a noncompliant ventricle.
3. A patient presents with polyuria, polydipsia, and polyphagia. Which
lab test confirms the diagnosis?
A. HbA1c
B. Lipid panel
C. Liver function test
,D. CBC
Answer: A
Rationale: HbA1c ≥ 6.5 % confirms diabetes mellitus, reflecting 3-
month glucose control.
4. The nurse notes crackles in both lower lobes. This finding most
likely indicates:
A. Asthma
B. Pulmonary edema
C. Pneumothorax
D. Pleural effusion
Answer: B
Rationale: Crackles are caused by fluid in alveoli, common in
pulmonary edema or heart failure.
5. Which antihypertensive drug is contraindicated in pregnancy?
A. Methyldopa
B. Labetalol
C. ACE inhibitors
D. Hydralazine
Answer: C
Rationale: ACE inhibitors can cause fetal renal damage and are
contraindicated during pregnancy.
6. In a patient with COPD, which physiological change is most
expected?
, A. Decreased residual volume
B. Increased alveolar elasticity
C. Air trapping and hyperinflation
D. Decreased pulmonary compliance
Answer: C
Rationale: Loss of elastic recoil leads to air trapping, increased residual
volume, and hyperinflation.
7. Which physical finding supports a diagnosis of right-sided heart
failure?
A. Crackles
B. Peripheral edema
C. Orthopnea
D. Pulmonary congestion
Answer: B
Rationale: Right-sided failure causes systemic venous congestion →
jugular venous distention and edema.
8. What is the primary function of the liver in drug metabolism?
A. Excretion
B. Biotransformation
C. Absorption
D. Distribution
Answer: B
Rationale: The liver metabolizes drugs via oxidation, reduction, and
conjugation to make them easier to excrete.
