resource with zero question repetition.
Section 1: Assessment & Diagnosis (Questions 1–60)
1. A 45-year-old female presents with fatigue, pallor, and spoon-shaped
nails. Her CBC shows microcytic, hypochromic anemia. Which is the most
likely underlying cause?
A. Vitamin B12 deficiency
B. Iron deficiency
C. Chronic liver disease
D. Aplastic anemia
Answer: B. Iron deficiency
Explanation: Iron deficiency leads to decreased hemoglobin synthesis,
producing microcytic, hypochromic red cells. Spoon-shaped nails
(koilonychia) are a classic feature. Vitamin B12 deficiency produces
,macrocytic anemia. Chronic liver disease and aplastic anemia do not
typically present with microcytic anemia.
2. A patient with Type 2 diabetes mellitus presents with burning pain and
numbness in both feet. Which medication provides symptomatic relief of
neuropathic pain?
A. Lisinopril
B. Metformin
C. Duloxetine
D. Glipizide
Answer: C. Duloxetine
Explanation: Duloxetine is an SNRI effective for diabetic neuropathy. ACE
inhibitors like lisinopril control blood pressure but do not relieve
neuropathic pain. Metformin and glipizide are used for glycemic control, not
neuropathic pain.
3. Which physical exam finding most strongly suggests bacterial
pneumonia?
A. Diffuse wheezing
B. Crackles and bronchial breath sounds over one lobe
C. Hyperresonance to percussion
D. Pleural friction rub
Answer: B. Crackles and bronchial breath sounds over one lobe
Explanation: Localized crackles and bronchial breath sounds indicate
alveolar consolidation typical of bacterial pneumonia. Diffuse wheezing
suggests asthma or COPD. Hyperresonance suggests pneumothorax.
Pleural friction rub suggests pleurisy.
4. A 23-year-old woman presents with dysuria and urinary frequency.
Urinalysis shows positive nitrites and leukocyte esterase. The first-line
,treatment is:
A. Ciprofloxacin for 10 days
B. Trimethoprim-sulfamethoxazole for 3 days
C. Nitrofurantoin for 5 days
D. Amoxicillin for 7 days
Answer: C. Nitrofurantoin for 5 days
Explanation: Nitrofurantoin is a first-line treatment for uncomplicated
cystitis due to low resistance rates. Fluoroquinolones are reserved for
complicated infections. TMP-SMX resistance rates are high in many areas.
5. A 17-year-old presents with sore throat, fever, and posterior cervical
lymphadenopathy. A Monospot test is positive. Which drug should be
avoided?
A. Acetaminophen
B. Amoxicillin
C. Ibuprofen
D. Acyclovir
Answer: B. Amoxicillin
Explanation: Amoxicillin in patients with Epstein-Barr virus infection
(mononucleosis) commonly produces a maculopapular rash, thus it should
be avoided. Acetaminophen and ibuprofen are safe for symptom
management.
6. Which of the following lipid-lowering agents can cause myopathy,
especially when combined with statins?
A. Ezetimibe
B. Fibrates
C. Niacin
D. Bile acid sequestrants
, Answer: B. Fibrates
Explanation: Gemfibrozil and other fibrates interfere with statin metabolism
via CYP pathways, increasing myopathy risk. Ezetimibe, niacin, and bile acid
sequestrants do not significantly increase this risk.
7. A 3-year-old boy presents with a barking cough and inspiratory stridor.
Which diagnosis is most likely?
A. Epiglottitis
B. Croup (laryngotracheobronchitis)
C. Bronchiolitis
D. Asthma
Answer: B. Croup (laryngotracheobronchitis)
Explanation: Viral croup causes subglottic inflammation leading to the
characteristic "barking" cough and inspiratory stridor. Epiglottitis presents
with drooling and tripod positioning. Bronchiolitis presents with wheezing in
infants.
8. A 65-year-old woman presents with a fasting lipid profile showing
cholesterol 240 mg/dL, HDL 30 mg/dL, and LDL 200 mg/dL. She is a
smoker. In addition to therapeutic lifestyle changes, what is the most
appropriate initial pharmacological treatment?
A. Bile acid sequestrant
B. Cholesterol absorption inhibitor
C. Low-dose aspirin
D. Statin drug
Answer: D. Statin drug
Explanation: Statins are first-line therapy for hyperlipidemia with elevated
LDL, especially in patients with cardiovascular risk factors like smoking and
family history of premature heart disease.
