,Q1. A patient presents with sudden severe headache, neck stiffness, and photophobia.
CSF analysis shows elevated opening pressure, neutrophils >1000/mm³, elevated
protein, and low glucose. Which pathogen is most likely, and which empirical
antibiotic regimen is recommended?
A. Streptococcus pneumoniae; ceftriaxone plus vancomycin
B. Neisseria meningitidis; ceftriaxone alone
C. Listeria monocytogenes; ampicillin plus gentamicin
D. Haemophilus influenzae; cefotaxime
Correct Answer: A. Streptococcus pneumoniae; ceftriaxone plus vancomycin
Rationale: The CSF profile (neutrophilic pleocytosis, elevated protein, low glucose) is
classic for acute bacterial meningitis. In adults, the leading pathogens are Streptococcus
pneumoniae and Neisseria meningitidis, but since pneumococcal meningitis has high
mortality, empirical therapy includes ceftriaxone plus vancomycin to cover resistant
pneumococci. Ceftriaxone alone is insufficient for resistant S. pneumoniae. Listeria is
more common in immunocompromised/elderly; ampicillin is added only if risk factors
exist. H. influenzae is less common in adults.
Why Wrong:
B - Ceftriaxone alone does not cover cephalosporin-resistant Streptococcus
pneumoniae, which is a growing concern.
C - Listeria is more likely in immunocompromised or elderly patients, not the typical
adult profile; empiric therapy should cover pneumococcus.
D - H. influenzae is less common in adults, and cefotaxime alone does not provide
adequate coverage for resistant pneumococcus.

Diseases, 9th Ed., Ch. 87
Q2. Which of the following best explains the pathophysiological mechanism of
angioedema induced by angiotensin-converting enzyme (ACE) inhibitors?
A. IgE-mediated mast cell degranulation
B. Accumulation of bradykinin due to reduced degradation
C. Direct histamine release from basophils
D. Autoantibody-mediated complement activation
Correct Answer: B. Accumulation of bradykinin due to reduced degradation
Rationale: ACE inhibitors block the breakdown of bradykinin, a potent vasodilator that
increases vascular permeability, leading to angioedema. This is not IgE-mediated (that
would be anaphylaxis), nor does it involve direct histamine release or autoantibodies. The
onset can be anytime during therapy, and it is a known class effect.
Why Wrong:
A - IgE-mediated reactions cause urticaria and anaphylaxis, not the
bradykinin-mediated angioedema typical of ACE inhibitors.
Page 3
, C - Direct histamine release is seen with opioids or radiocontrast, not ACE inhibitors.
D - Autoantibody-mediated complement activation is seen in hereditary angioedema
types with C1 inhibitor deficiency, not ACE inhibitor-induced.

Q3. A patient with chronic kidney disease (GFR 25 mL/min) develops new-onset
atrial fibrillation. Which of the following anticoagulation strategies is most
appropriate, and why?
A. Apixaban 5 mg BID, because it has minimal renal excretion
B. Warfarin, because it is safer in renal impairment
C. Dabigatran 150 mg BID, because it has a rapid onset
D. Rivaroxaban 20 mg daily, because it is once-daily dosing
Correct Answer: A. Apixaban 5 mg BID, because it has minimal renal excretion
Rationale: Apixaban is the preferred direct oral anticoagulant (DOAC) in advanced
chronic kidney disease (CrCl 15-29 mL/min) because it has the least renal clearance
(~27%) and is FDA-approved for this population. Warfarin is not inherently safer; it
requires monitoring and has higher bleeding risk in CKD. Dabigatran is largely renally
cleared and contraindicated in severe renal impairment. Rivaroxaban 20 mg is not
recommended for CrCl <30 mL/min.
Why Wrong:
B - Warfarin is not safer; it has a narrow therapeutic window and increased bleeding
risk in CKD.
C - Dabigatran is contraindicated in severe renal impairment due to high renal
clearance.
D - Rivaroxaban 20 mg is not recommended when CrCl <30 mL/min; dose reduction
or avoidance is advised.

Q4. A 45-year-old patient presents with episodic hypertension, palpitations,
diaphoresis, and headache. Plasma metanephrines are elevated. Which of the
following is the most appropriate next step in management after tumor localization?
A. Start alpha-blocker (phenoxybenzamine) 7-14 days preoperatively, then
beta-blocker
B. Start beta-blocker first to control tachycardia
C. Proceed directly to surgery without alpha blockade
D. Start calcium channel blocker alone for blood pressure control
Correct Answer: A. Start alpha-blocker (phenoxybenzamine) 7-14 days
preoperatively, then beta-blocker
