Question 1
A 45-year-old male is diagnosed with active tuberculosis. Which medication
should be included in the initial treatment regimen to prevent antibiotic resistance?
A) Isoniazid alone
B) Rifampin alone
C) Rifampin in combination with other antituberculous drugs
D) Pyrazinamide alone
E) Ethambutol alone
ANSWER>>>C
RATIONALE: Rifampin is an antibiotic used to treat TB, but it must be given in
combination with other antituberculous drugs to prevent the development of
antibiotic resistance. Monotherapy with rifampin or any single agent leads to rapid
resistance. The standard regimen includes isoniazid, rifampin, pyrazinamide, and
ethambutol.
Question 2
A 28-year-old female with a urinary tract infection is prescribed trimethoprim-
sulfamethoxazole. She has a history of sulfa allergy. Which of the following is the
most appropriate alternative?
A) Ciprofloxacin
B) Nitrofurantoin
C) Amoxicillin
,D) Doxycycline
E) Azithromycin
ANSWER>>>B
RATIONALE: Nitrofurantoin is a first-line agent for uncomplicated UTIs and is
safe in patients with sulfa allergy. It is not a sulfonamide and does not cross-react
with sulfa allergies. Fluoroquinolones like ciprofloxacin are alternatives but have
more side effects and resistance concerns.
Question 3
A 65-year-old male with community-acquired pneumonia is prescribed
levofloxacin. Which adverse effect requires immediate discontinuation?
A) Nausea
B) Headache
C) Tendonitis or tendon rupture
D) Dizziness
E) Rash
ANSWER>>>C
RATIONALE: Fluoroquinolones like levofloxacin carry a black box warning for
tendonitis and tendon rupture, particularly in elderly patients and those on
corticosteroids. This adverse effect requires immediate discontinuation. Nausea,
headache, and dizziness are common but not emergent.
Question 4
A 32-year-old female with a penicillin allergy presents with streptococcal
pharyngitis. Which antibiotic is most appropriate?
A) Amoxicillin
B) Azithromycin
C) Cephalexin
D) Doxycycline
E) Clindamycin
ANSWER>>>B
,RATIONALE: Azithromycin is an appropriate alternative for Group A
streptococcal pharyngitis in patients with penicillin allergy. Cephalosporins have
cross-reactivity with penicillins and should be avoided in severe allergies.
Doxycycline and clindamycin are less effective for strep pharyngitis.
Question 5
A 55-year-old male with methicillin-resistant Staphylococcus aureus (MRSA)
infection is receiving vancomycin. Which parameter should be monitored to ensure
therapeutic efficacy?
A) Serum creatinine
B) Vancomycin trough levels
C) Complete blood count
D) Liver function tests
E) Serum potassium
ANSWER>>>B
RATIONALE: Vancomycin trough levels should be monitored to ensure
therapeutic efficacy and prevent toxicity. Trough levels of 10-20 mcg/mL are
recommended for serious MRSA infections. Serum creatinine is monitored for
nephrotoxicity but not efficacy.
Question 6
A 70-year-old female with a urinary tract infection is prescribed ciprofloxacin. She
has a history of prolonged QT syndrome. Which medication should be avoided?
A) Nitrofurantoin
B) Ciprofloxacin
C) Amoxicillin
D) Doxycycline
E) Trimethoprim-sulfamethoxazole
ANSWER>>>B
RATIONALE: Fluoroquinolones including ciprofloxacin can prolong the QT
interval and should be avoided in patients with prolonged QT syndrome.
, Nitrofurantoin, amoxicillin, and doxycycline are safer alternatives. TMP-SMX is
also an option but less effective for complicated UTIs.
Question 7
A 45-year-old male with cellulitis is prescribed cephalexin. He has a history of
penicillin allergy with anaphylaxis. What is the most appropriate management?
A) Give cephalexin with diphenhydramine
B) Avoid cephalexin and choose alternative
C) Administer cephalexin with epinephrine available
D) Perform skin testing before giving cephalexin
E) Reduce cephalexin dose
ANSWER>>>B
RATIONALE: Cephalosporins have cross-reactivity with penicillins, particularly
in patients with severe penicillin allergy (anaphylaxis). Cephalexin should be
avoided in patients with a history of penicillin anaphylaxis. Alternative antibiotics
such as clindamycin or vancomycin should be used.
Question 8
A 32-year-old female with an uncomplicated UTI is prescribed nitrofurantoin.
Which instruction should be given regarding administration?
A) Take on an empty stomach
B) Take with food to improve absorption
C) Take with grapefruit juice
D) Take at bedtime only
E) Take without any liquid
ANSWER>>>B
RATIONALE: Nitrofurantoin should be taken with food to improve absorption
and reduce gastrointestinal side effects. It is not affected by grapefruit juice.
Taking on an empty stomach may cause nausea and reduce absorption.
