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
