A nurse is caring for a client who has heart failure and a new prescription for furosemide.Which of the following laboratory values should the nurse review before administering furosemide?
Bicarbonate.
Potassium.
Phosphate.
Carbon dioxide.
The Correct Answer is B
Choice B rationale
Potassium levels should be reviewed before administering furosemide. Furosemide is a loop diuretic that can cause significant potassium loss through increased urine output. Monitoring potassium is crucial to prevent hypokalemia, which can lead to cardiac arrhythmias and other serious complications.
Choice A rationale
Bicarbonate levels are not directly impacted by furosemide use and are less critical to review in this context. While they are important in assessing acid-base balance, they are not the primary concern when administering furosemide.
Choice C rationale
Phosphate levels are not typically affected by furosemide and are not the main focus before administration. Monitoring phosphate might be important in other scenarios, but it is not directly relevant here.
Choice D rationale
Carbon dioxide levels are more relevant to respiratory function and acid-base balance but are not directly impacted by furosemide. The focus should be on monitoring electrolytes, particularly potassium, to prevent complications from diuretic therapy.

Correct Answer is C
Explanation
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.
Correct Answer is A
Explanation
Choice A rationale
Total parenteral nutrition (TPN) provides essential nutrients intravenously, allowing the bowel to rest and heal, which is important in the management of inflammatory bowel disease (IBD).
Choice B rationale
While reducing inflammation and controlling symptoms are important goals in IBD management, TPN is primarily used to provide nutrition and allow the bowel to rest.
Choice C rationale
Stimulating the bowel is not the purpose of TPN. TPN is used to give the digestive tract a break while ensuring the patient receives necessary nutrients.
Choice D rationale
Preventing malnutrition and promoting weight gain are secondary benefits of TPN, but the primary rationale is to provide nutrients while allowing the bowel to rest and heal.
