A nurse is preparing a client for discharge home after an admission for bilateral pulmonary emboli. The client is prescribed warfarin in addition to regular daily medications. Which of the following actions should the nurse take?
Advise the client that over-the-counter medications remain safe to consume as needed.
Consult the pharmacist about potential interactions between the client’s regular medications and warfarin.
Recommend the client take warfarin at the same time as other medications.
Tell the client they can continue to drink cranberry juice while taking warfarin.
The Correct Answer is B
Choice A reason: Advising over-the-counter medications as safe is incorrect, as many, like NSAIDs, increase warfarin’s bleeding risk by inhibiting platelets or affecting liver metabolism. Warfarin’s narrow therapeutic index requires careful management to prevent hemorrhage, making broad safety claims dangerous without specific evaluation.
Choice B reason: Consulting the pharmacist identifies interactions with warfarin, a vitamin K antagonist metabolized by CYP450 enzymes. Many drugs alter warfarin’s efficacy, risking thrombosis or bleeding. Pharmacist expertise ensures safe polypharmacy, maintaining therapeutic INR levels critical for managing pulmonary emboli effectively.
Choice C reason: Recommending warfarin with other medications ignores interaction risks and timing needs. Warfarin’s absorption is unaffected by timing, but CYP450 interactions can alter INR. This advice is irrelevant to safety, missing the need for individualized regimen assessment to prevent complications in anticoagulation therapy.
Choice D reason: Cranberry juice may enhance warfarin’s effect by inhibiting CYP2C9, increasing INR and bleeding risk. Advising its use without monitoring is unsafe, as dietary factors can destabilize anticoagulation, potentially causing hemorrhage in clients with pulmonary emboli, requiring careful dietary guidance.

Correct Answer is B
Explanation
Choice A reason: Washing hands for 10 seconds with hot water is insufficient; at least 20 seconds with soap and warm water is recommended to remove pathogens post-gardening. Hot water alone is ineffective, so this statement reflects incomplete understanding, making it incorrect.
Choice B reason: Visiting a nephew with chickenpox 5 days after sores crust indicates understanding, as the virus is no longer contagious then. This aligns with CDC guidelines for varicella, protecting the pregnant client and fetus, making it the correct statement.
Choice C reason: Cleaning a cat’s litter box during pregnancy risks toxoplasmosis, which can harm the fetus. Pregnant women should avoid this task, so this statement shows a lack of understanding, making it incorrect for infection prevention.
Choice D reason: Avoiding anyone with a cold sore is overly restrictive, as herpes simplex transmission requires direct contact. General avoidance without context reflects misunderstanding, as precautions like avoiding kissing suffice, making this incorrect.
Correct Answer is C
Explanation
Choice A reason: Referring to a mental health clinic addresses potential emotional distress but not the adolescent’s primary concern of affordability. Pregnancy increases psychological stress, but financial barriers to prenatal care are critical. This action fails to ensure access to medical resources, essential for maternal and fetal health in adolescent pregnancy.
Choice B reason: Contacting the adolescent’s parent risks breaching confidentiality, depending on legal guidelines, and does not address financial concerns directly. Family dynamics may complicate support, and without consent, this action could increase stress, failing to provide immediate healthcare access critical for a healthy pregnancy outcome.
Choice C reason: Assisting with Medicaid application directly addresses financial concerns, ensuring access to prenatal care, delivery, and postpartum support. Medicaid reduces risks like preterm birth by covering medical and nutritional needs, critical for adolescent mothers with limited resources, aligning with public health goals for maternal-fetal well-being.
Choice D reason: Advising adoption is premature and overlooks the adolescent’s autonomy. Adoption requires extensive counseling, not immediate recommendation. It fails to address healthcare access, critical for a healthy pregnancy. This approach dismisses financial solutions, potentially increasing stress and undermining informed decision-making in pregnancy.
