A client receives a prescription for a secondary infusion of IV erythromycin 1 gram in 200 mL dextrose 5% in water (DW) to be infused in 90 minutes. The nurse should program the Infusion pump to deliver how many ml/hour? (Enter the numerical value only. If rounding is required, round to the nearest whole number.)

A) A decreased peak and trough level may indicate subtherapeutic levels of the medication but do not pose an immediate risk to the client. Adjustments to the dosing regimen may be needed, but this finding does not require immediate action.

B) A decreased trough level alone may suggest a need for dosage adjustment but does not present an immediate risk to the client. It is important to monitor therapeutic drug levels, but this finding does not require immediate reporting to the healthcare provider.

C) An increased peak and trough level indicates potential toxicity of the medication. Increased peak levels can lead to nephrotoxicity, while increased trough levels can lead to ototoxicity. Both conditions are serious and require immediate action to prevent harm to the client. The nurse should report this finding immediately to the healthcare provider for further evaluation and possible adjustment of the medication regimen.

D) A decreased peak level alone may indicate subtherapeutic levels of the medication, but it does not pose an immediate risk to the client. Adjustments to the dosing regimen may be needed, but this finding does not require immediate action.

A) Asking the client to describe how she takes the medication is the most appropriate initial response by the nurse. “Heartburn” reported after taking risedronate raises concerns about potential esophageal irritation or gastroesophageal reflux disease (GERD) exacerbation. Understanding the client’s administration technique (e.g., whether she takes the medication with a full glass of water and remains upright for at least 30 minutes afterward) can help identify potential causes of the reported symptoms.

B) While suggesting the use of an antacid two hours after the medication may provide symptomatic relief, it does not address the underlying issue of potential esophageal irritation or GERD exacerbation related to risedronate administration. Moreover, if the client’s symptoms are due to esophageal irritation, using an antacid may mask the symptoms without addressing the cause.

C) Reminding the client to take the medication with plenty of water is a standard recommendation for bisphosphonate administration to minimize the risk of esophageal irritation and ensure proper drug absorption. However, since the client is already experiencing “heartburn,” further assessment of the client’s medication administration technique is warranted before providing this reminder.

D) Advising the client to go to the nearest emergency department is not appropriate at this stage, as the reported symptom of “heartburn” does not suggest an immediate life-threatening emergency. However, if the client experiences severe chest pain, difficulty swallowing, or signs of a severe allergic reaction (e.g., swelling of the face or throat, difficulty breathing), emergency medical attention would be necessary.

Therefore, the nurse should first assess the client’s medication administration technique to determine if improper administration may be contributing to the reported symptoms. Based on this assessment, appropriate interventions can be provided to address potential esophageal irritation or GERD exacerbation.
