The emergency department nurse is administering IV lidocaine to patients.
What adverse effect of lidocaine therapy should the nurse assess for?

Choice A rationale

ACE inhibitors can cause teratogenic effects, meaning they can harm a developing fetus. Therefore, precautions should be taken to avoid pregnancy while taking these drugs.

Choice B rationale

Spermicidal jellies alone are not a highly reliable form of contraception. For women taking ACE inhibitors, a more reliable method of contraception is recommended to prevent pregnancy.

Choice C rationale

The minipill, a progestin-only contraceptive, is not the contraceptive of choice when the risk of teratogenic effects from ACE inhibitors is considered. Barrier methods are preferred to avoid potential drug interactions.

Choice D rationale

Barrier contraception, such as condoms or diaphragms, is recommended for women taking ACE inhibitors to prevent pregnancy due to the teratogenic risk associated with these drugs.

Choice A rationale

Sumatriptan does not cause vasodilation of peripheral blood vessels. Instead, it has vasoconstrictive properties.

Choice B rationale

Sumatriptan does not depress pain response in the central nervous system. Its primary action is on the cranial blood vessels.

Choice C rationale

Sumatriptan is a selective serotonin receptor agonist that causes vasoconstriction of cranial blood vessels, relieving migraine headaches.

Choice D rationale

Sumatriptan does not bind to acetylcholine receptors or prevent nerve transmission. It specifically targets serotonin receptors in cranial blood vessels.
