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?

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.

Choice A rationale

The nurse should plan to refrigerate the urine during the collection time period. This is because the urine needs to be kept cool to prevent the breakdown of certain analytes that might be measured in the urine.

Choice B rationale

The nurse should not discard the client’s last void at the end of the collection time period. The last voided specimen should be included in the collection to ensure that the 24-hour collection is complete.

Choice C rationale

The nurse should not include toilet paper with the collected urine. Toilet paper could contaminate the urine sample and interfere with the accuracy of the test results.

Choice D rationale

The nurse should not save the first void at the start of the collection time period. The first voided specimen should be discarded, and the collection should start with the next void.
