Question

a nurse is teaching a client who has a prescription for zileuton. which of the following instructions should the nurse include? check heart rate before taking the medication. take the medication only as needed before exercising. rinse mouth after using the medication. have laboratory tests performed at regular intervals.

Explanation:

Zileuton is a leukotriene inhibitor used for asthma. It carries a risk of liver toxicity, so regular laboratory tests (like liver function tests) are required to monitor liver health. The other options are incorrect: checking heart rate is not indicated for this medication, it is taken regularly (not just before exercise), and rinsing the mouth is for inhaled steroids, not oral zileuton.

Answer:

D. Have laboratory tests performed at regular intervals.
