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 A
Explanation
Choice A rationale
A decreased white blood cell count indicates the body's response to infection is improving, showing the effectiveness of the antibiotics.

Increased chest pain and shortness of breath would suggest worsening of the condition, not improvement.
Choice C rationale
Adventitious breath sounds and increased cough are signs that pneumonia may be persisting or worsening.

Improved appetite and weight gain are positive signs but are not direct indicators of the effectiveness of antibiotic treatment.
Correct Answer is ["A","B","E"]
Explanation
Choice A rationale
Serum creatinine is assessed annually to evaluate kidney function, as diabetes can lead to nephropathy and renal impairment.
Choice B rationale
Urine for microalbuminuria is important to detect early kidney damage, which can occur in diabetic nephropathy.
Choice C rationale
Hearing (audio) exam is not a standard annual test for diabetic complications. Diabetes primarily affects the vascular system, kidneys, and nerves.
Choice D rationale
Chest x-ray is not routinely performed annually for diabetes management. It is used when there are specific indications such as respiratory symptoms.
Choice E rationale
Monofilament testing of the foot is conducted annually to detect diabetic neuropathy and prevent foot ulcers and infections.
