Correct Answer is A

No explanation

A. Cleanse the top of the can of formula with an alcohol wipe. B. Keep the formula cold until instillation. C. Withhold the feeding if the residual volume is 150 mL. D. Flush the tube with 30 mL of sterile water before the feeding.

Correct Answer is D

Explanation

Correct answer: D

A.While it is important to ensure the can of formula is clean, it should be wiped with soap and water or a disinfectant wipe, not an alcohol wipe.

B.Cold formula can cause gastric discomfort or cramping. It's recommended to bring the formula to room temperature before administration to avoid gastric irritation and enhance comfort during feeding.

C.The action of withholding the feeding depends on the institution's protocol and the specific clinical condition of the client. Typically, residuals greater than 200 mL might indicate delayed gastric emptying, but the threshold can vary. A residual volume of 150 mL may not necessarily require withholding the feeding, though it may warrant further assessment.

D.It is standard practice to flush the NG tube with 30 mL of sterile water (or as per facility guidelines) before administering an enteral feeding. This helps ensure the tube is patent, reduces the risk of clogging, and ensures the feeding formula flows smoothly. Flushing before the feeding also helps clear the tube of any residual formula, preventing cross-contamination.
