RATIONALES (100% CORRECT VERIFIED SOLUTIONS) LATEST
UPDATED VERSION |GUARANTEED PASS A+
1. What is the first-line treatment for acute asthma exacerbation?
A) Oral corticosteroids
B) Short-acting beta-agonist (SABA) inhaler
C) Long-acting beta-agonist (LABA) inhaler
D) Leukotriene receptor antagonist
Correct Answer: b) short-acting beta-agonist (Saba) inhaler
Rationale: SABAs, such as albuterol, provide rapid bronchodilation and
are first-line for acute asthma exacerbations. Oral corticosteroids may be
added for moderate to severe attacks.
2. Which laboratory finding is most indicative of bacterial infection?
A) Elevated C-reactive protein (CRP) and neutrophilia
B) Lymphocytosis
C) Eosinophilia
D) Normal white blood cell count
,Correct Answer: a) elevated c-reactive protein (crop) and neutrophilia
Rationale: Bacterial infections typically increase neutrophils and CRP,
while viral infections often cause lymphocytosis.
3. A patient present with chest pain relieved by leaning forward. Which
condition is most likely?
A) Myocardial infarction
B) Pulmonary embolism
C) Pericarditis
D) Pneumothorax
Correct Answer: c) pericarditis
Rationale: Chest pain relieved by sitting up and leaning forward is
classic for pericarditis, often with pericardial friction rub on
auscultation.
4. Which medication is first-line for acute decompensated heart failure
with pulmonary edema?
A) Intravenous furosemide
B) Oral digoxin
C) Oral beta-blocker
D) Intravenous nitroglycerin only
, Correct Answer: a) intravenous furosemide
Rationale: IV loop diuretics are used to rapidly reduce pulmonary
congestion in acute decompensated heart failure. Nitroglycerin may be
adjunctive.
5. Which of the following is the most appropriate initial diagnostic test
for suspected pulmonary embolism?
A) Chest X-ray
B) Ventilation-perfusion (V/Q) scan or CT pulmonary angiography
C) EKG
D) Echocardiogram
Correct Answer: b) ventilation-perfusion (v/q) scan or CT pulmonary
angiography
Rationale: CT pulmonary angiography is the gold standard for
diagnosing pulmonary embolism; V/Q scan is an alternative if contrast is
contraindicated.
6. Which medication is indicated for atrial fibrillation with rapid
ventricular response?
A) Amiodarone
B) Adenosine
C) Metoprolol
