Question

the healthcare provider has prescribed digoxin for a client who has been taking furosemide for six months. what laboratory serum levels should the nurse review before administering the digoxin?
○ calcium.
○ magnesium.
○ potassium.
○ furosemide.

Explanation:

Furosemide is a diuretic that can cause potassium loss (hypokalemia). Digoxin toxicity risk increases with low potassium levels. So, before giving digoxin, the nurse should check potassium levels. Calcium, magnesium, and furosemide levels aren't the key here for digoxin administration safety related to furosemide - induced electrolyte changes.

Answer:

C. Potassium.
