The patient with systemic edema is given Lasix to reduce the edema. A serious side effect of this diuretic is the promotion of hypokalemia, which may result in:
impaired kidney function
delayed blood clotting
systemic edema
cardiac complications
The Correct Answer is D
A. impaired kidney function: Although hypokalemia can affect renal concentrating ability, this is not the primary concern.
B. delayed blood clotting: Delayed clotting is more commonly associated with calcium deficiency, not potassium imbalance.
C. systemic edema: Diuretics like Lasix reduce edema, not cause it.
D. cardiac complications: Hypokalemia can cause dangerous cardiac dysrhythmias such as premature ventricular contractions and even ventricular fibrillation.
