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 D
Explanation
A. Increased urine output. Infants with congestive heart failure (CHF) often have decreased urine output due to reduced kidney perfusion caused by poor cardiac function.
B. Bradycardia. CHF is more likely to cause tachycardia as the heart compensates for poor circulation.
C. Increased blood pressure. CHF in infants typically leads to hypotension or normal blood pressure rather than an increase.
D. Tachypnea. Increased respiratory rate (tachypnea) is a common sign of CHF in infants because of fluid overload and pulmonary congestion, which make breathing difficult.
Correct Answer is D
Explanation
A. "You should consider finding other hobbies to participate in instead of sports." Avoiding sports altogether is not necessary for children with asthma. Many children with well-managed asthma can safely participate in sports with proper precautions.
B. "You shouldn't feel frustrated, because you can find other options for exercise." This response dismisses the child's feelings instead of acknowledging them and providing a solution.
C. "You will be able to exercise if you use your peak expiratory flow meter twice per day." While monitoring peak expiratory flow (PEF) is important for asthma management, it does not directly enable participation in sports.
D. "You can participate in sports if you use your rescue inhaler before practice or games." Using a short-acting bronchodilator (such as albuterol) before exercise is a common strategy to prevent exercise-induced bronchoconstriction, allowing children with asthma to safely participate in sports.
