The nurse is providing discharge instructions to a patient who has a prescription for phenytoin. Which of the following information should the nurse include?

Choice A rationale:
Flu-like symptoms: These are common during the early stages of HIV infection, often within 2-4 weeks after exposure to the virus. They are a result of the body's immune system responding to the virus. Symptoms can include:
Fever Fatigue

Muscle aches

Headache Sore throat

Rash

Swollen lymph nodes
Night sweats: These are also common in early HIV infection and can be caused by the body's attempts to fight off the virus or by inflammation. They can also be a side effect of some HIV medications.

Choice B rationale:
Kaposi's sarcoma (KS): This is a type of cancer that is associated with HIV infection. It is caused by a virus called Kaposi's sarcoma-associated herpesvirus (KSHV). KS often appears as purple or red lesions on the skin or in the mouth. It can also affect other organs, such as the lungs and lymph nodes. However, it's not a common initial symptom of HIV infection. It usually develops in later stages of HIV when the immune system is severely weakened.

Choice C rationale:
Fungal and bacterial infections: People with HIV are more susceptible to infections because the virus weakens their immune system. However, fungal and bacterial infections are not typically among the initial symptoms of HIV infection. They usually occur in later stages of the disease when the immune system is more compromised.

Choice D rationale:
Pneumocystis lung infection (PCP): This is a serious lung infection that is caused by a fungus called Pneumocystis jirovecii. It is a common opportunistic infection in people with HIV, but it is not typically an initial symptom. It usually develops in later stages of HIV when the CD4 count (a measure of immune system health) is very low.

Choice A rationale:
Phenytoin is an anticonvulsant medication that is typically used long-term to control seizures. It is not a medication that can be stopped abruptly, as this can lead to the recurrence of seizures or even status epilepticus, a life-threatening condition characterized by continuous seizure activity.
The client's statement, "I'll be glad when I can stop taking this medicine," indicates a lack of understanding about the long- term nature of phenytoin therapy and the potential risks associated with stopping the medication prematurely.
Further teaching is needed to emphasize the importance of medication adherence and the potential consequences of non- adherence.

Choice B rationale:
Phenytoin can cause gingival hyperplasia (overgrowth of gum tissue), so it is important for clients taking this medication to see a dentist regularly for checkups and cleanings.
The client's statement, "I have made an appointment to see my dentist next week," indicates an understanding of this potential side effect and the need for regular dental care.

Choice C rationale:
Phenytoin has a narrow therapeutic index, meaning that there is a small difference between the effective dose and the toxic dose.
Switching brands of phenytoin can lead to changes in blood levels of the medication, which could potentially result in therapeutic failure or toxicity.
The client's statement, "I know that I cannot switch brands of this medication," indicates an understanding of this important safety consideration.

Choice D rationale:
Phenytoin can interact with many other medications, including over-the-counter medications and herbal supplements.
It is important for clients taking phenytoin to notify their doctor before taking any other medications to avoid potential drug interactions.
The client's statement, "I will notify my doctor before taking any other medications," indicates an understanding of this potential risk.
