A nurse is caring for a client whose serum potassium level is 5.3 mEq/L. Which of the following scheduled medications should the nurse plan to administer?
Digoxin
Lisinopril
Potassium iodide
Furosemide
The Correct Answer is D
A. Digoxin: Digoxin requires caution with elevated potassium levels, as hyperkalemia can increase the risk of digoxin toxicity. A potassium level of 5.3 mEq/L is borderline high, so it should be used cautiously.
B. Lisinopril: Lisinopril, an ACE inhibitor, can also increase potassium levels. It may not be the best choice for this client due to the elevated potassium.
C. Potassium iodide: Potassium iodide would further increase the client's potassium level and is contraindicated.
D. Furosemide: Furosemide is a loop diuretic that can help to lower serum potassium levels by promoting potassium excretion. Therefore, it is appropriate for this client with an elevated potassium level.

Correct Answer is B
Explanation
A. The patient is hypertensive. Hypertension is not a prerequisite for starting BPH medication; in fact, some BPH medications can lower blood pressure.
B. The patient has had a prostate examination, including measurement of the PSA level. A prostate examination and PSA measurement are important for diagnosing BPH and ruling out prostate cancer before starting treatment.
C. The patient is still sexually active. Sexual activity status is not a determining factor for administering BPH medication.
D. The patient has not had a vasectomy. Vasectomy status does not influence the treatment of BPH.
Correct Answer is C
Explanation
A. Urine-specific gravity: While urine-specific gravity can provide information on kidney function, it does not specifically measure renal impairment or disease progression, especially in SLE.
B. Serum potassium: Serum potassium levels can be affected by renal function but are not a direct indicator of renal health and can be influenced by many other factors.
C. Serum creatinine: Serum creatinine is a more reliable indicator of renal function, as it reflects how well the kidneys are filtering waste. In clients with SLE, kidney involvement is a common complication.
D. Serum sodium: Serum sodium levels do not directly indicate renal function, though kidney impairment can impact electrolyte levels.
