A patient with acute renal failure (ARF) is admitted due to uncontrolled type 1 diabetes mellitus and hyperkalemia. The nurse administers an IV dose of regular insulin per sliding scale.
What is the most important intervention for the nurse to include in this patient’s plan of care?

Monitor the patient’s cardiac activity via telemetry.

Assess glucose via fingerstick every 4 to 6 hours.

Evaluate hourly urine output for return of normal renal function.

Maintain venous access with an infusion of normal saline.

Answer and Explanation

The Correct Answer is A

Choice A rationale

Monitoring the patient’s cardiac activity via telemetry is the most important intervention for a patient with acute renal failure (ARF), uncontrolled type 1 diabetes mellitus, and hyperkalemia who is receiving an IV dose of regular insulin. Hyperkalemia can cause cardiac arrhythmias and other cardiac complications. Therefore, continuous cardiac monitoring is crucial to detect any changes in heart rhythm or rate that could indicate worsening hyperkalemia.
Choice B rationale
While assessing glucose via fingerstick every 4 to 6 hours is important for a patient with uncontrolled type 1 diabetes mellitus, it is not the most important intervention in this scenario. The patient’s hyperkalemia and ARF pose more immediate risks.
Choice C rationale
Evaluating hourly urine output for return of normal renal function is an important part of monitoring a patient with ARF34. However, in the context of hyperkalemia and the administration of insulin, cardiac monitoring is more critical.
Choice D rationale
Maintaining venous access with an infusion of normal saline is a standard nursing intervention for most hospitalized patients, but it is not the most important intervention in this scenario.

Correct Answer is D

Explanation

Choice A rationale
Using a cushion when sitting can provide comfort but does not directly address the client’s electrolyte imbalance, elevated blood pressure, or weight gain.
Choice B rationale

Offering a high protein diet can be beneficial for clients with hepatic failure to support liver regeneration and prevent malnutrition. However, it does not directly address the client’s immediate issues.
Choice C rationale
Providing only distilled water does not address the client’s electrolyte imbalance, elevated blood pressure, or weight gain. In fact, it could potentially exacerbate electrolyte imbalances.
Choice D rationale
Documenting abdominal girth can help monitor for fluid accumulation (ascites), a common complication of hepatic failure that can contribute to weight gain and elevated blood pressure.

A. 1000, 1600, 2200, 0400. B. Administer with meals and a bedtime snack. C. Give in equally divided doses during waking hours. D. 0800, 1200, 1600, 2000.

Correct Answer is D

Explanation

Choice A rationale
Administering the medication at 1000, 1600, 2200, and 0400 would not be the best schedule because it does not evenly distribute the doses throughout the day. This could lead to periods of subtherapeutic medication levels and periods of potential toxicity.
Choice B rationale
Administering the medication with meals and a bedtime snack is not the best schedule for this medication. While some medications need to be administered with food, there is no indication

that this medication needs to be. Furthermore, this schedule could lead to uneven distribution of the medication throughout the day.
Choice C rationale
Giving the medication in equally divided doses during waking hours is not the best schedule because it does not take into account the half-life of the medication or the patient’s sleep schedule. This could lead to subtherapeutic levels of the medication during the night.
Choice D rationale
Administering the medication at 0800, 1200, 1600, and 2000 is the best schedule for this medication. It evenly distributes the doses throughout the day, which can help maintain a therapeutic level of the medication and reduce the risk of toxicity.
