A nurse is caring for a 2-month-old infant who has heart failure. Which of the following actions should the nurse take?

Limit oral feedings to 30 min in length.

Weigh the infant every other day.

Place the infant in the prone position for naps.

Check the infant’s oxygen saturation every 6 hr.

Answer and Explanation

The Correct Answer is A

This is because infants with heart failure have difficulty feeding and may become exhausted or dyspneic during prolonged feedings. By limiting the feeding time, the nurse can reduce the energy expenditure and caloric needs of the infant.
Choice B is wrong because weighing the infant every other day is not enough to monitor the fluid status and nutritional intake of the infant. The nurse should weigh the infant daily at the same time using the same scale.
Choice C is wrong because placing the infant in a prone position can compromise respiratory function and increase the risk of sudden infant death syndrome (SIDS). The nurse should place the infant in a semi-Fowler’s position to facilitate breathing and decrease venous return.
Choice D is wrong because checking the infant’s oxygen saturation every 6 hr is not frequent enough to detect hypoxia or cyanosis. The nurse should monitor the oxygen saturation continuously or at least every 2 hr.

Correct Answer is D

Explanation

This prescription is complete because it includes the medication name, dose, route, and frequency. A complete prescription should also include the client’s name, date, time, signature of the prescriber, and any special instructions.

Choice A is wrong because it does not specify the dose of cimetidine.

PO twice daily is not enough information to administer the medication safely. Choice B is wrong because it does not specify the frequency of tetracycline.

200 mg PO is not enough information to administer the medication safely. Choice C is wrong because it does not specify the route of epoetin alfa.

150 units/kg three times weekly is not enough information to administer the medication safely.

Normal ranges for digoxin are 0.5 to 2 ng/mL for heart failure and 0.8 to 2 ng/mL for atrial fibrillation.

Normal ranges for cimetidine are 50 to 150 ng/mL. Normal ranges for tetracycline are 1 to 10 mcg/mL.

Normal ranges for epoetin alfa are not applicable as it is a synthetic hormone that stimulates red blood cell production.

A. Measure gastric residual volumes every 4 hr. B. Advance the rate of the feeding every 2 hr. C. Maintain the head of the bed at a 20° angle. D. Flush the NG tube with 30 mL 0.9% sodium chloride before and after medication.

Correct Answer is A

Explanation

This is because continuous enteral feedings through an NG tube can increase the risk of aspiration, which is the inhalation of food or fluids into the lungs. Measuring gastric residual volumes (GRV) can help monitor the tolerance and absorption of the feedings and prevent overfeeding. GRV is the amount of fluid aspirated from the stomach via an enteral tube to check for gastric emptying. The normal range of GRV is less than 200 ml.

Choice B is wrong because advancing the rate of the feeding every 2 hr can lead to overfeeding, abdominal distension, nausea, vomiting and diarrhea.

The rate of the feeding should be adjusted according to the client’s nutritional needs and tolerance.

Choice C is wrong because maintaining the head of the bed at a 20° angle is not enough to prevent aspiration. The head of the bed should be elevated at least 30° to 45° during and for at least one hour after feeding.

Choice D is wrong because flushing the NG tube with 30 mL 0.9% sodium chloride before and after medication is not related to continuous enteral feedings. This is a practice to prevent clogging of the tube and ensure proper delivery of medication. Flushing the tube with water before and after feeding is also recommended to maintain patency and hydration.
