A nurse is reviewing urinary laboratory results. Which findings should prompt the nurse to follow up?

Choice A rationale

While gastric acid can cause dyspepsia, measuring gastric residual is not primarily done to remove gastric acid.

Choice B rationale

Measuring gastric residual is primarily done to identify delayed gastric emptying. This is important because delayed gastric emptying can lead to complications such as aspiration pneumonia.

Choice C rationale

Gastric residual does not directly determine the patient’s electrolyte balance.

Choice D rationale

While confirming the placement of the NG tube is important, it is not the primary purpose of measuring gastric residual.

Choice A rationale

Donning sterile gloves before inserting the indwelling urinary catheter is a critical step to prevent infection. The urinary tract is normally sterile, and using sterile gloves helps maintain this sterility during the procedure.

Choice B rationale

Applying an oil-based lubricant to the indwelling urinary catheter is not recommended. Oil- based lubricants can damage latex catheters and increase the risk of infection. A water-soluble lubricant is typically used.

Choice C rationale

Using one cotton swab to clean the client’s genitalia is not sufficient. Proper cleaning and disinfection of the area are crucial to prevent introducing bacteria into the urinary tract during catheter insertion.

Choice D rationale

Testing the balloon on the indwelling urinary catheter before insertion is not typically done. The balloon is usually inflated with sterile water once the catheter is in place to ensure that it remains in the bladder.
