A nurse is planning care for a newborn who has hyperbilirubinemia and is to receive phototherapy. Which of the following interventions should the nurse include?

- A. Clothing the newborn in light cotton is not recommended because it can block the light from reaching the skin, which is necessary for the treatment of hyperbilirubinemia through phototherapy.
- B. Checking the newborn's temperature every 8 hours is not frequent enough; during phototherapy, it is important to monitor the newborn's temperature more frequently to ensure they do not become too cold or too warm as a result of the therapy.
- C. Administering water between feedings is not recommended as it can interfere with the newborn's feeding schedule and nutrition; breast milk or formula provides adequate hydration unless otherwise indicated by a healthcare provider.
- D. Placing the newborn 45 cm (18 in) from the light source is the correct intervention. This distance allows for optimal exposure to the light while ensuring the safety and comfort of the newborn, as recommended in clinical guidelines for effective phototherapy.

A. Metoprolol is a beta-blocker used to treat hypertension and other cardiovascular conditions.

While it may be important for the provider to be aware of all medications, it is not the priority to report in this scenario.

B. Clopidogrel is an antiplatelet medication used to prevent blood clots in individuals at risk for cardiovascular events. While it may have implications for the procedure, it is not the priority to report in this scenario.

C. Metformin is an oral antidiabetic medication commonly used to treat type 2 diabetes. It is

important to report because there may be specific considerations regarding its use in the context of a colonoscopy, such as the risk of lactic acidosis.

D. Digoxin is a medication used to treat heart failure and certain arrhythmias. While it may have implications for the procedure, it is not the priority to report in this scenario.
