1.A patient with COPD develops hypercapnia. What is the primary cause?
A. Increased oxygen binding
B. Decreased respiratory drive
C. Alveolar hypoventilation
D. Increased tidal volume
Answer: C. Alveolar hypoventilation
Rationale: COPD leads to airflow limitation and air trapping, causing
inadequate ventilation and CO₂ retention.
2.
Which electrolyte imbalance is most associated with peaked T waves?
A. Hypokalemia
B. Hyperkalemia
C. Hyponatremia
D. Hypercalcemia
Answer: B. Hyperkalemia
Rationale: Elevated potassium alters cardiac conduction, producing peaked
T waves and risk of arrhythmia.
3.
First-line treatment for anaphylaxis?
A. Diphenhydramine
,B. Corticosteroids
C. Epinephrine
D. Albuterol
Answer: C. Epinephrine
Rationale: Epinephrine reverses airway edema, vasodilation, and
hypotension rapidly.
4.
Most common cause of hyperthyroidism?
A. Hashimoto’s
B. Graves’ disease
C. Thyroid cancer
D. Iodine deficiency
Answer: B. Graves’ disease
Rationale: Graves’ is an autoimmune condition causing excess thyroid
hormone production.
5.
Which medication decreases preload in heart failure?
A. Lisinopril
B. Furosemide
C. Metoprolol
D. Digoxin
Answer: B. Furosemide
Rationale: Loop diuretics reduce fluid volume, lowering preload.
6.
, What is the hallmark lab finding in iron deficiency anemia?
A. Elevated MCV
B. Decreased ferritin
C. Elevated B12
D. Increased reticulocytes
Answer: B. Decreased ferritin
Rationale: Ferritin reflects iron stores and is low in iron deficiency anemia.
7.
Severe hypertension with end-organ damage is:
A. Urgency
B. Emergency
C. Stage 1
D. White coat
Answer: B. Emergency
Rationale: Hypertensive emergency involves acute target organ damage.
8.
Primary neurotransmitter deficiency in Parkinson’s?
A. Serotonin
B. Dopamine
C. Acetylcholine
D. GABA
Answer: B. Dopamine
Rationale: Loss of dopaminergic neurons in substantia nigra causes
symptoms.
