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 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.
Correct Answer is B
Explanation
A. Respiratory distress syndrome occurs in babies with frequent colds. This statement is inaccurate; respiratory distress syndrome (RDS) is not associated with frequent colds.
B. Respiratory distress syndrome occurs in premature and low-birth-weight babies. This statement accurately describes RDS, as it is primarily seen in premature infants due to insufficient surfactant production.
C. Respiratory distress syndrome occurs in babies with genetic allergies. RDS is not directly related to genetic allergies; it is a condition primarily linked to prematurity and lung maturity.
D. Respiratory distress syndrome occurs in babies stressed during the pregnancy. While stress during pregnancy can affect outcomes, RDS is specifically associated with lung development in premature infants rather than stress alone.
