A nurse is caring for an infant who has otitis media and is to receive amoxicillin 30 mg/kg/day in divided doses every 12 hr. The child weighs 13 lb. How many mg should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["89"]
Determine the infant's weight in kg:13 lb ÷ 2.2 = 5.91 kg
Calculate the total daily dose:30 mg/kg/day × 5.91 kg = 177.3 mg/day
Divide the total daily dose by 2 (since the medication is given every 12 hours):177.3 mg ÷ 2 = 88.65 mg per dose
Round to the nearest whole number:89 mg per dose

Correct Answer is A
Explanation
A. "Lifts head 45° when lying prone." By 2 months of age, infants begin lifting their heads about 45 degrees while on their stomachs, which is an early sign of developing neck and upper body strength.
B. "Rolls over from back to abdomen." Rolling from back to abdomen typically occurs around 6 months of age.
C. "No head lag when pulled into a sitting position." Head lag is still present at 2 months, but it gradually disappears by 4 months as neck muscles strengthen.
D. "Rolls over from abdomen to back." Rolling from abdomen to back typically occurs around 4 months of age, followed by rolling from back to abdomen at about 6 months.
Correct Answer is {"dropdown-group-1":"A","dropdown-group-2":"A"}
Explanation
Severe Pain Management: The child's pain increased from 7/10 to 10/10, indicating worsening vaso-occlusive crisis. IV hydromorphone (Dilaudid) is a strong opioid analgesic commonly used for severe sickle cell pain when first-line options (e.g., morphine) are insufficient. Swelling and warmth in the right knee suggest ongoing vaso-occlusion and inflammation. Increased blood pressure (120/74 mm Hg) and respiratory rate (25/min) likely indicate pain-related distress.
