Question

Quizplus · Accepted Answer

Furosemide is a potent diuretic that works by inhibiting the reabsorption of sodium, chloride, and water in the loop of Henle. It can cause significant loss of water and electrolytes, especially potassium. In this case, the patient has lost 6.6 lb (or 3 kg) over a 48-hour period, which equates to approximately 3 L of water. The correct choice is D. Choice A is incorrect as the patient would likely be hypokalemic, not hyperkalemic, due to the use of a kaliuretic diuretic. Choice B is incorrect as losing 12 L of water in two days is excessive and potentially life-threatening. Finally, choice C is incorrect as "tenting" refers to the skin’s inability to return to its original position after being pinched or pulled – it is not a relevant finding in this patient.
