QUESTIONS AND CORRECT
ANSWERS WITH RATIONALES
GRADED A+ LATEST
1. A 35-year-old female presents with fever, dysuria, and flank pain.
Urinalysis shows positive nitrites and leukocyte esterase. She has no known
drug allergies. Which antibiotic regimen is the most appropriate initial
treatment?
A. Nitrofurantoin for 5 days
B. Trimethoprim-sulfamethoxazole for 3 days
C. Ceftriaxone followed by oral TMP-SMX for 7 days
D. Ciprofloxacin for 3 days
Answer: C
Rationale:
Pyelonephritis requires broader coverage and longer treatment than cystitis.
Empiric IV ceftriaxone followed by oral TMP-SMX for 7 days is appropriate.
Nitrofurantoin and short-course TMP-SMX are for uncomplicated cystitis.
Fluoroquinolones are reserved due to resistance concerns.
2. A patient with uncontrolled hypertension and chronic kidney disease
(eGFR 35) needs medication. Which antihypertensive class is most
appropriate to start?
A. Thiazide diuretic
B. ACE inhibitor
C. Calcium channel blocker
D. Loop diuretic
,MEDSTUDY.COM
Answer: B
Rationale:
ACE inhibitors are renal-protective and reduce proteinuria in CKD. Thiazides are
less effective when eGFR <30. Loop diuretics are for volume overload, not first-
line for hypertension. CCBs are alternative but not preferred over ACE inhibitors
in CKD with proteinuria.
3. A 68-year-old male presents with sudden onset chest pain radiating to the
left arm. ECG shows ST-elevation in leads II, III, and aVF. What is the most
appropriate next step?
A. Begin thrombolytic therapy
B. Administer aspirin and arrange PCI
C. Order a stress test
D. Start heparin and observe
Answer: B
Rationale:
STEMI requires immediate reperfusion. Aspirin + urgent PCI is the gold standard.
Thrombolytics are used when PCI is not available within the required time frame.
Stress tests are contraindicated in acute MI.
4. A patient presents with fatigue, pallor, and spoon-shaped nails. Lab shows
microcytic hypochromic anemia. What is the most likely cause?
A. Vitamin B12 deficiency
B. Iron deficiency
C. Hemolytic anemia
D. Anemia of chronic disease
Answer: B
Rationale:
Microcytic hypochromic anemia with spoon nails suggests iron deficiency. B12
deficiency causes macrocytic anemia. Hemolytic anemia is normocytic. Anemia of
chronic disease is usually mild and normocytic/microcytic.

5. A 55-year-old with type 2 diabetes reports numbness and burning in the
feet. What is the best initial treatment?
A. Gabapentin
B. Insulin
C. Metformin
D. High-dose vitamin B12
Answer: A
Rationale:
Peripheral neuropathy is treated symptomatically with gabapentin or pregabalin.
Insulin and metformin treat glycemic control but not neuropathic pain directly.
B12 is only indicated if deficiency is present.
6. A patient has suspected deep vein thrombosis. Which diagnostic test is most
appropriate initially?
A. D-dimer
B. Venous Doppler ultrasound
C. CT angiography
D. MRI
Answer: A
Rationale:
D-dimer is the best initial test in low to moderate risk patients. Ultrasound is
confirmatory if D-dimer is positive or if high clinical suspicion exists.
7. A patient with COPD presents with acute worsening shortness of breath.
Which of the following is most appropriate for acute management?
A. Inhaled corticosteroid
B. Short-acting beta agonist + anticholinergic
C. Long-acting beta agonist
D. Oral montelukast
, MEDSTUDY.COM
Answer: B
Rationale:
Acute COPD exacerbation requires rapid bronchodilation using SABA +
anticholinergic. Inhaled steroids and LABA are for chronic control, not acute
rescue.
8. A 25-year-old female presents with sudden severe right lower quadrant
pain, nausea, and rebound tenderness. What is the most likely diagnosis?
A. Ectopic pregnancy
B. Appendicitis
C. Ovarian torsion
D. Urinary tract infection
Answer: B
Rationale:
Classic presentation of appendicitis includes RLQ pain, nausea, and rebound
tenderness. Ectopic pregnancy must be ruled out in women of childbearing age.
Ovarian torsion can mimic but usually has adnexal tenderness and ultrasound
findings.
9. A 40-year-old patient with chronic GERD is diagnosed with Barrett’s
esophagus. Which management is most appropriate?
A. Lifestyle changes only
B. Proton pump inhibitor and surveillance endoscopy
C. H2 blocker and antacid PRN
D. Surgical fundoplication
Answer: B
Rationale:
Barrett’s esophagus requires acid suppression and periodic surveillance due to
cancer risk. Lifestyle changes alone are insufficient. Surgery is reserved for
refractory cases.
