A nurse is caring for a client who has a new diagnosis of essential hypertension. The nurse should monitor the client for which of the following findings that is consistent with this diagnosis?

Placing the client on his side is an essential action to take during a seizure, as it can prevent airway obstruction and aspiration. The client should be placed on his side, preferably in a lateral recumbent position, to allow saliva and secretions to drain from the mouth.

Holding the client's arms and legs from moving is not appropriate, as it can cause injury, increase agitation, or prolong the seizure. The client should be allowed to move freely during a seizure, but supported and guided away from hazards.

Placing the client back in bed is not necessary, as it can cause harm or delay care. The client should be left on the floor, unless it is unsafe or uncomfortable, and padded with pillows or blankets to protect from injury.

Inserting a tongue blade in the client's mouth is not advisable, as it can cause oral trauma, choking, or damage to the teeth. The client should not have anything inserted into his mouth during a seizure, as he cannot swallow or bite his tongue. The nurse should ensure that the client's airway is clear and patent.

Phenytoin is an anticonvulsant medication that is used to prevent and treat seizures. It works by stabilizing the electrical activity of the brain and reducing the spread of abnormal impulses. Phenytoin is usually taken for life or until the seizures are controlled by other means, such as surgery or diet. The client should not stop taking phenytoin without consulting their doctor, as this can cause withdrawal symptoms or increase the risk of seizures.

The other options are correct and indicate that the client understands the discharge teaching because:

1. "I have made an appointment to see my dentist next week." This statement is correct because phenytoin can cause gingival hyperplasia, which is an overgrowth of gum tissue that can lead to bleeding, infection, or difficulty chewing. The client should practice good oral hygiene and see their dentist regularly to prevent or treat this condition.

1. "I will notify my doctor before taking any other medications." This statement is correct because phenytoin can interact with many other medications, such as antibiotics, anticoagulants, oral contraceptives, or antacids. These interactions can affect the blood levels and effectiveness of phenytoin or the other medications, causing adverse effects or reduced seizure control. The client should inform their doctor of any other medications they are taking or planning to take, including over-the-counter, herbal, or dietary supplements.
2. "I know that I cannot switch brands of this medication." This statement is correct because different brands of phenytoin may have different formulations or bioavailability, which can affect the absorption and metabolism of the drug. Switching brands can cause changes in the blood levels and effectiveness of phenytoin, leading to toxicity or reduced seizure control. The client should always use the same brand of phenytoin and check with their pharmacist if they notice any changes in the appearance or labeling of their medication.
