Question

Which of the following is a common adverse effect of furosemide (Lasix)?

1. Weight gain
2. Bradycardia
3. Hypotension
4. Vomiting

Answer 1

Hypotension is a common adverse effect of furosemide (Lasix) due to its mechanism of increasing urination and decreasing blood volume.

Step-by-step explanation:

A common adverse effect of furosemide (Lasix), which is a loop diuretic, is hypotension. Loop diuretics increase urination by inhibiting the reabsorption of sodium (Na+) and chloride (Cl-) ions in the ascending limb of the loop of Henle, which can lead to decreased blood volume and subsequently lower blood pressure. The decrease in blood volume can also cause dehydration, further contributing to hypotension. Although vomiting can also occur with furosemide, hypotension is more directly related to the diuretic's mechanism of action and its common side effects. Hence, the most fitting answer to the question is option 3, hypotension.
