A nurse is preparing to administer medications to a 5-month-old infant.Tympanic temperature 39.2°C (102.6°F). Heart rate 84/min.Respiratory rate 30/min.Blood pressure 80/30 mmHg.Oxygen saturation 96% on 0.5 L oxygen via nasal cannula.Weight 7.2 kg (15.9 lb). The nurse should clarify the prescription for which medication?

Choice A rationaleIbuprofen should be clarified before administration to a 5-month-old infant. Ibuprofen is not recommended for infants younger than 6 months due to the risk of adverse effects on the kidneys and gastrointestinal tract. Infants have immature renal function, and administering ibuprofen can increase the risk of nephrotoxicity. Additionally, ibuprofen can cause gastric irritation and increase the risk of gastrointestinal bleeding. The nurse should verify the safety and appropriateness of this medication with the prescribing healthcare provider before administration.Choice B rationaleAcetaminophen is generally considered safe for use in infants to reduce fever and alleviate pain. It is often the preferred antipyretic for infants younger than 6 months due to its favorable safety profile. Acetaminophen does not have the same risks of nephrotoxicity and gastrointestinal irritation as ibuprofen, making it a suitable choice for managing fever in this age group.Choice C rationaleThe heart rate of 84/min is within the normal range for a 5-month-old infant. Heart rate itself is not a medication and does not require clarification. Instead, it is a vital sign that should be monitored to assess the infant's overall condition and response to treatment.Choice D rationaleTemperature itself is not a medication and does not require clarification. It is a vital sign that indicates the body's response to infection or inflammation. The nurse should monitor the infant's temperature and provide appropriate interventions, such as antipyretics like acetaminophen, to manage fever. .
