Patient education on medication purpose, dosage, and side effects ( 7 Questions)
A client is receiving phenytoin for seizure prevention. The nurse should instruct the client to avoid which of the following over-the-counter medications while taking phenytoin?
Incorrect. Acetaminophen is a non-opioid analgesic that can be used safely with phenytoin. However, the nurse should advise the client to limit their intake of acetaminophen to no more than 4 g per day, as higher doses can cause liver toxicity.
Incorrect. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that can be used safely with phenytoin. However, the nurse should advise the client to monitor for signs of bleeding, such as bruising, petechiae, and hematuria, as NSAIDs can inhibit platelet aggregation and increase the risk of bleeding.
Incorrect. Diphenhydramine is an antihistamine that can be used safely with phenytoin. However, the nurse should advise the client to avoid driving or operating machinery while taking diphenhydramine, as it can cause drowsiness and impair mental alertness.
Correct. Ginkgo biloba is an herbal supplement that can interact with phenytoin and reduce its effectiveness. Ginkgo biloba can induce hepatic enzymes that increase the metabolism and clearance of phenytoin, leading to subtherapeutic levels and increased risk of seizures.
