Question 1
What is the most effective drugs for prevention and treatment of seasonal and
perennial rhinitis?
A. Sympathomimetics
B. Intranasal glucocorticoids
C. Oral steroids
D. Diphenhydramine
Correct Answer: B. Intranasal glucocorticoids
Rationale: Intranasal glucocorticoids (e.g., fluticasone, mometasone) are the most
effective medications for both prevention and treatment of allergic rhinitis. They reduce
inflammation by suppressing multiple inflammatory mediators (cytokines, chemokines,
and adhesion molecules). They are more effective than antihistamines or
sympathomimetics for controlling nasal congestion, sneezing, itching, and rhinorrhea.
Oral steroids are reserved for severe cases due to systemic side effects.
Question 2
Bacterial meningitis is best treated with which generation of cephalosporins?
,A. 1st generation
B. 3rd generation
C. 2nd generation
D. 4th generation
Correct Answer: B. 3rd generation
Rationale: Third-generation cephalosporins (e.g., ceftriaxone, cefotaxime) are the drugs
of choice for bacterial meningitis because they achieve high concentrations in the
cerebrospinal fluid (CSF) and have excellent activity against the most common causative
organisms (Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus
influenzae). They cross the blood-brain barrier better than earlier generations.
Question 3
What medication should we employ for the treatment of glaucoma with COPD or
asthma?
A. Timolol
B. Betaxolol
C. Latanoprost
D. Alphagan
Correct Answer: C. Latanoprost
Rationale: Latanoprost is a prostaglandin analog and is the preferred first-line treatment
for glaucoma in patients with COPD or asthma. Beta-blockers like Timolol and Betaxolol
are contraindicated in patients with reactive airway disease because they can cause
bronchospasm. Latanoprost works by increasing uveoscleral outflow and does not affect
pulmonary function. Betaxolol is a cardioselective beta-blocker but still carries some risk
in COPD/asthma patients.
Question 4
At what BMI level should bariatric surgery be considered?
, A. BMI of 30 or more
B. BMI of 35 or more
C. BMI of 40 or more
D. BMI of 25 or more
Correct Answer: C. BMI of 40 or more (or BMI ≥35 with obesity-related comorbidities)
Rationale: According to NIH guidelines, bariatric surgery is indicated for patients with a
BMI ≥40 kg/m² (severe obesity) or BMI ≥35 kg/m² with at least one obesity-related
comorbidity (e.g., type 2 diabetes, hypertension, sleep apnea). BMI of 30-34.9 is
considered Class I obesity and is generally managed with lifestyle modifications and
pharmacotherapy rather than surgery.
Question 5
_ ___ is less effective than intranasal glucocorticoids for sneezing, itching, rhinorrhea,
and nasal itching.
A. Pseudoephedrine
B. Loratadine
C. Flonase
D. Brimonidine
Correct Answer: B. Loratadine
Rationale: Loratadine is a second-generation antihistamine that is effective for sneezing,
itching, and rhinorrhea but is less effective than intranasal glucocorticoids for controlling
all symptoms of allergic rhinitis, particularly nasal congestion. Intranasal glucocorticoids
(e.g., Flonase/fluticasone) are the most effective class for all nasal symptoms.
Pseudoephedrine is a decongestant; Flonase is an intranasal glucocorticoid; Brimonidine
is used for glaucoma.
Question 6
What class of antibiotics is most likely to promote C. diff infection?
