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 A
Explanation
A. Diabetes mellitus: Diabetes mellitus is a significant risk factor for UTIs due to elevated glucose levels in the urine, which provides an environment conducive to bacterial growth.
B. Anemia: Anemia does not directly increase the risk of UTIs. UTIs are more related to factors affecting the urinary tract and immune function rather than blood cell count.
C. Osteoporosis: Osteoporosis does not increase susceptibility to UTIs, as it primarily affects bone density and strength.
D. COPD: COPD is a lung condition and does not have a direct connection to an increased risk for UTIs.
Correct Answer is ["C","D","E"]
Explanation
A. Stimulate production of androgens: The kidneys do not stimulate androgen production. Androgens are produced primarily by the adrenal glands and gonads.
B. Stimulate production of white blood cells: The kidneys do not stimulate white blood cell production. This is mainly a function of the bone marrow.
C. Excrete various drugs and drug metabolites: The kidneys play a key role in filtering and excreting drugs and drug metabolites, helping to remove them from the body.
D. Produce urine: The primary function of the kidneys is to filter blood and produce urine, which is then excreted to remove waste products and maintain fluid balance.
E. Regulate acid/base balance: The kidneys are essential in maintaining acid-base balance by excreting hydrogen ions and reabsorbing bicarbonate, which helps regulate the pH level in the body.
