1. A 6-year-old child presents with fever, sore throat, and

swollen lymph nodes. The nurse practitioner suspects

streptococcal pharyngitis and orders a rapid antigen test,

which is positive. What is the most appropriate antibiotic

therapy for this child?

A) Amoxicillin for 10 days

B) Azithromycin for 5 days

C) Cephalexin for 7 days

D) Penicillin V for 10 days

Answer: D) Penicillin V for 10 days

Rationale: Penicillin V is the drug of choice for

streptococcal pharyngitis in children, as it is effective,

inexpensive, and has a narrow spectrum of activity.

Amoxicillin, azithromycin, and cephalexin are alternative

options for patients who are allergic to penicillin or have

recurrent infections.

2. A 12-year-old girl comes to the clinic for a well-child

visit. She reports having menarche 6 months ago and

having regular menstrual cycles every 28 days. She denies

any sexual activity or use of contraception. The nurse

practitioner performs a physical examination and notes that

the girl has Tanner stage 4 breast development and pubic

hair. What is the most appropriate screening test for this

girl at this visit?

A) Pap smear

B) Human papillomavirus (HPV) vaccine

C) Chlamydia and gonorrhea testing
