A nurse inadvertently administers 160 mg of valsartan PO to a client who was scheduled to receive 80 mg.

Which of the following actions is the priority for the nurse to take?

The correct answer is choice A. Measure gastric residual volumes every 4 hr.

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.

Choice A reason:

"Plan to take this medication with food." Is the correct statement. When providing instructions to an older adult client who has a seizure disorder and is prescribed phenytoin (an antiepileptic or anticonvulsant medication), the nurse should advise the client to take the medication with food. Phenytoin can cause gastrointestinal irritation, and taking it with food can help minimize this side effect.

Choice B reason:

"Plan to take this medication with antacids. “is not the appropriate instruction. Phenytoin should not be taken with antacids. Antacids can reduce the absorption of phenytoin, leading to decreased effectiveness of the medication. If antacids are needed for other reasons, they should be taken at least 2 hours before or after taking phenytoin.

Choice C reason:

"Limit foods that contain vitamin D while taking this medication. “This is not inappropriate instruction. There is no specific requirement to limit foods containing vitamin D while taking phenytoin. However, phenytoin may decrease the absorption of vitamin D, which could potentially affect the client's vitamin D levels. Therefore, it is essential for the client to have regular check-ups and possibly discuss the need for vitamin D supplementation with their healthcare provider.

Choice D reason:

"Limit foods that contain folic acid while taking this medication. “This is not the correct statement. Phenytoin can interfere with the absorption of folic acid (a B-vitamin). Long-term use of phenytoin may lead to folic acid deficiency. Therefore, the nurse should instruct the client to consume foods rich in folic acid and discuss the potential need for folic acid supplementation with their healthcare provider.
