A nurse is preparing to instill 840 mL of enteral nutrition via a patient’s gastrostomy tube over 24 hours using an infusion pump.

How many mL/hr should the nurse set the infusion pump to deliver?

Answer and Explanation

The Correct Answer is ["35"]

Step 1 is: To find out how many mL/hr the nurse should set the infusion pump to deliver, we need to divide the total volume of enteral nutrition (840 mL) by the total time (24 hours).

So, the calculation is: 840 mL ÷ 24 hours = 35 mL/hr Therefore, the nurse should set the infusion pump to deliver 35 mL/hr.

Correct Answer is B

Explanation

Choice A rationale

Troponin is a cardiac enzyme which indicates a client has experienced a myocardial infarction. It is not a laboratory test that supports a diagnosis of malnutrition.

Choice B rationale

Albumin is a measure of plasma proteins which reflects the nutritional condition of a client experiencing anorexia and malnutrition over an extended period of time. Therefore, a nurse

should expect altered albumin levels in a client who reports anorexia and is experiencing malnutrition.

Choice C rationale

Total bilirubin is altered in clients who are experiencing hepatobiliary disease. It is not a laboratory test that supports a diagnosis of malnutrition.

Choice D rationale

Creatine kinase is a cardiac enzyme which is useful in the diagnosis of a myocardial infarction. It is not a laboratory test that supports a diagnosis of malnutrition.

Correct Answer is ["125"]

Explanation

Step 1 is to understand the question. The patient has been prescribed vancomycin 1 g in 250 mL dextrose 5% (D5W) to be administered over 2 hours via IV intermittent bolus. We need to calculate how many mL/hr the nurse should set the IV pump to deliver.

Step 2 is to calculate the rate. The total volume to be administered is 250 mL and the time for administration is 2 hours. So, the rate is 250 mL ÷ 2 hours = 125 mL/hr.
