True or false: lasix can accelerate drug toxicities.
-
True
-
False
Correct Answer
A. TrueExplanation
Lasix, also known as furosemide, is a diuretic medication that helps the body get rid of excess water and salt through urine. It can accelerate drug toxicities because it increases the excretion of certain drugs from the body, leading to higher drug concentrations and potentially increasing the risk of adverse effects or toxicity. This is particularly important to consider when prescribing or administering medications in combination with Lasix.Rate this question:
