What is an important question for a nurse to ask a female client starting on an angiotensin II receptor blocker?

The most important question for a nurse to ask a female client starting on an angiotensin II receptor blocker is about the timing of her last menstrual period. This inquiry is particularly relevant because some medications, including angiotensin II receptor blockers, carry potential risks during pregnancy. It is essential for healthcare providers to ascertain whether a woman is of childbearing age and whether she is pregnant or may become pregnant while on the medication. Certain classes of blood pressure medications can cause harm to a developing fetus, and knowing the patient's menstrual status helps ensure patient safety and encourages appropriate counseling regarding effective contraception if necessary. Hence, understanding a female patient's reproductive status is critical when initiating treatment with these types of medications.
