How long should a 4-year-old child recovering from rheumatic fever need to receive monthly injections of penicillin G?
5 years
10 years
2 years
1 year
The Correct Answer is A
A. 5 years: The American Heart Association recommends that children with rheumatic fever (without carditis) receive secondary prophylaxis with monthly benzathine penicillin G for at least 5 years or until age 21 (whichever is longer), to prevent recurrence.
B. 10 years: This duration is typically for children with carditis, not for those recovering without cardiac involvement.
C. 2 years: Too short. Recurrence risk remains for years after the initial illness.
D. 1 year: Inadequate duration to prevent recurrence of streptococcal infection and rheumatic fever.

Correct Answer is B
Explanation
A. "I do not plan to offer my baby a pacifier during naps or at bedtime.": Pacifier use during sleep is associated with a reduced risk of SIDS. Not offering it may increase risk.
B. "My baby will be placed on her back when sleeping.": Placing infants on their backs to sleep is the safest position and is strongly recommended to prevent SIDS.
C. "Our baby will sleep in my bed because I am breastfeeding.": Bed-sharing increases the risk of SIDS due to potential suffocation or overlay; room-sharing without bed-sharing is recommended.
D. "We will place an antique quilt in our baby's crib.": Soft bedding, including quilts, increases the risk of suffocation and SIDS. The crib should have a firm mattress with a fitted sheet only.
Correct Answer is ["5.6"]
Explanation
Convert 33 lb to kg: 33 ÷ 2.2 = 15 kg
30 mg/kg/day × 15 kg = 450 mg/day
Every 12 hr → 450 ÷ 2 = 225 mg/dose
200 mg in 5 mL → 225 mg = (225 × 5) ÷ 200 = 5.625 mL
Round to nearest tenth = 5.6 mL
