A client presents to the clinic with intense itching at night and is diagnosed with Pinworms. The nurse anticipates the client would be placed on which medication to treat this condition?

Choice A reason: Zidovudine (Retrovir) is an antiretroviral medication used to treat HIV infection. It works by inhibiting the replication of the virus but has no efficacy against parasitic infections such as pinworms. Therefore, prescribing zidovudine for pinworm treatment would be inappropriate and ineffective. Choice B reason: Lanoxin (Digoxin) is a cardiac glycoside used to treat heart conditions such as atrial fibrillation and heart failure. It is not an antiparasitic medication and does not have any action against pinworms. Therefore, it is not a relevant choice for treating pinworm infestation. Choice C reason: Mebendazole (Vermox) is an anthelmintic medication specifically used to treat parasitic worm infections, including pinworms. It works by inhibiting the worms' ability to absorb glucose, leading to their death. Mebendazole is the appropriate and effective treatment for pinworms, addressing the root cause of the symptoms. Choice D reason: Ciprofloxacin (Cipro) is a broad-spectrum antibiotic used to treat bacterial infections. While effective against a variety of bacterial pathogens, it has no efficacy against parasitic infections such as pinworms. Using ciprofloxacin to treat pinworms would not address the infection and is therefore incorrect.
