A 10-year-old patient is diagnosed with scabies. Appropriate treatment should include:
retapamulin topically twice a day for 5 days.
one dose of permethrin cream 5% topically.
topical clotrimazole 3 times a day for 7 days.
hydrocortisone cream 1% topically three times a day for 10 days.
The Correct Answer is B
Rationale:
A. Retapamulin is an antibiotic used for bacterial skin infections, not for scabies.
B. Permethrin 5% cream is the first-line treatment for scabies. It should be applied to the entire body from the neck down (and in infants, also the scalp and face) and left on for 8–14 hours before washing off. A single application is often sufficient, though a second dose may be recommended after 7–14 days if symptoms persist.
C. Clotrimazole is an antifungal used for dermatophyte infections and candidiasis, not for scabies.
D. Hydrocortisone 1% cream can help relieve itching and inflammation but does not treat the underlying scabies infestation.

Correct Answer is B
Explanation
Rationale:
A. Pneumonia typically causes crackles, wheezing, fever, and cough, but not acute stridor.
B. Epiglottitis is a life-threatening condition in infants and young children that causes acute stridor, drooling, fever, and respiratory distress. Stridor is a hallmark sign of upper airway obstruction in this scenario.
C. Bronchiolitis usually causes wheezing and respiratory distress, but stridor is less common unless severe upper airway involvement occurs.
D. Apnea refers to pauses in breathing and may be associated with cyanosis or bradycardia but does not cause stridor.
Correct Answer is B
Explanation
Rationale:
A. Testing 1–2 weeks after starting therapy is premature, as the full course of antibiotics has not yet been completed, and results may not accurately reflect treatment effectiveness.
B. One week after completion of nitrofurantoin therapy is recommended to assess the resolution of bacteriuria and confirm the effectiveness of treatment for acute cystitis in pregnant adolescents. This timing allows any remaining bacteria to be detected while minimizing false negatives.
C. Testing after 10 days of therapy initiation may still be during treatment, which is too early to confirm eradication.
D. Waiting 2 weeks after completion of therapy is not necessary; 1 week post-treatment is sufficient to evaluate effectiveness and ensure prompt follow-up.
