The nurse is preparing to give medications to a client who has been receiving long-term therapy with phenytoin (Dilantin). The nurse notes that the client has coarse facial features, hirsutism, and acne. What is the most appropriate nursing diagnosis for this client?

Phenytoin (Dilantin) can cause cosmetic side effects, such as coarse facial features, hirsutism, and acne, in some people¹²³. These side effects can affect the client's self-esteem, social interactions, and emotional well-being¹. The nurse should assess the client's perception of his or her appearance and provide support and education to cope with the changes¹.

Choice A is wrong because risk for infection related to immunosuppression is not a relevant nursing diagnosis for this client. Phenytoin can cause blood dyscrasias, such as leukopenia and thrombocytopenia, in some people¹²³. However, these side effects are not related to immunosuppression and do not increase the risk of infection¹. The nurse should monitor the client's blood counts and report any signs of bleeding or anemia to the provider¹.

Choice C is wrong because impaired skin integrity related to hypersensitivity reaction is not a relevant nursing diagnosis for this client. Phenytoin can cause allergic reactions, such as rash, fever, lymphadenopathy, and hepatitis, in some people¹²³. However, these side effects are not related to impaired skin integrity and do not cause skin breakdown or ulceration¹. The nurse should discontinue the medication and report any signs of hypersensitivity reaction to the provider¹.

Choice D is wrong because deficient knowledge related to self-care and medication management is not a relevant nursing diagnosis for this client. Phenytoin requires careful monitoring and education to ensure therapeutic and safe use¹²³. However, this nursing diagnosis does not address the client's specific concern about the cosmetic side effects of phenytoin¹. The nurse should provide information and counseling about the benefits and risks of phenytoin therapy and discuss alternative options with the provider if needed¹.
