The nurse is preparing to administer sodium polystyrene sulfonate (Kayexalate) rectally to a patient with an irregular pulse and weakness of the lower extremities.
What laboratory finding does the nurse determine is the reason for this treatment?

Choice A rationale

Infusing 10 percent dextrose and water prevents hypoglycemia if TPN is temporarily unavailable. This is a crucial step in maintaining the patient's blood sugar levels.

Choice B rationale

Shaking the TPN bag with fat emulsion can cause the emulsion to break, leading to potential complications. Fat emulsions should be mixed gently.

Choice C rationale

Maintaining the TPN infusion rate when behind schedule is incorrect as it can lead to rapid infusion and complications such as hyperglycemia and fluid overload.

Choice D rationale

Keeping the TPN refrigerated when not in use helps to maintain its stability and prevent bacterial contamination. Proper storage is essential for patient safety. .

Choice A rationale

Administering post-procedure antibiotics is not typically required for a bronchoscopy unless there is evidence of infection. The procedure itself does not inherently pose a high risk of infection requiring antibiotics as a preventative measure.

Choice B rationale

Providing pre-procedure sedation is important to ensure the client is comfortable and relaxed during the bronchoscopy. This helps minimize discomfort and anxiety associated with the procedure.

Choice C rationale

Ensuring the client is NPO (nothing by mouth) for a specific period before the procedure is crucial to prevent aspiration. Aspiration can occur if the client has food or liquid in their stomach, posing a serious risk during the insertion of the bronchoscope.

Choice D rationale

Encouraging the client to drink plenty of fluids before the procedure is not appropriate because the client needs to be NPO to prevent aspiration risks during the bronchoscopy.
