Question 1 of 5
A nurse is caring for a newly admitted patient who will receive Digoxin to treat cardiac dysrhythmia. The patient takes hydrochlorothiazide and reports regular use of OTC laxatives. Before administering the first dose of Digoxin, the nurse will review the patient's electrolyte levels with careful attention to which electrolytes?
Correct Answer: C
Rationale: The correct answer is C: Potassium and magnesium. Digoxin can cause toxicity in patients with low potassium or low magnesium levels, which can be exacerbated by the use of hydrochlorothiazide and OTC laxatives. Monitoring potassium and magnesium levels is crucial to prevent adverse effects such as cardiac dysrhythmias. Calcium and magnesium (choice
A) are important electrolytes, but potassium is more critical in the context of Digoxin therapy. Potassium and chloride (choice
B) are both important electrolytes, but magnesium should also be monitored. Sodium and calcium (choice
D) are not the most relevant electrolytes to monitor in this situation.
