Correct Answer is B
Explanation
A. Lantus insulin does not directly affect potassium levels in the same way that digoxin does.
B. A potassium level of 3.0 mEq/L is low, and digoxin toxicity can occur when potassium levels are low, leading to an increased risk of arrhythmias. This requires immediate attention to avoid serious complications.
C. Metoprolol is a beta-blocker that does not directly cause hypokalemia and is less of an immediate concern.
D. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that could affect kidney function but does not directly impact potassium levels as significantly as digoxin.
