A nurse is teaching a client who has angina pectoris about starting therapy with SL nitroglycerin tablets. The nurse should include which of the following instructions regarding how to take the medication?

Take this medication after each meal and at bedtime.

Take one tablet every 15 min during an acute atack.

Take this medication with 8 ounces of water.

Take one tablet at the first indication of chest pain.

Answer and Explanation

The Correct Answer is D

Taking one tablet at the first indication of chest pain is the correct way to use SL nitroglycerin tablets, as they are fast- acting and can relieve anginal symptoms within minutes. The client should place the tablet under the tongue and let it dissolve.

Taking this medication after each meal and at bedtime is not appropriate, as SL nitroglycerin tablets are not meant for routine or prophylactic use, but only for acute episodes of angina.

Taking one tablet every 15 min during an acute attack is not correct, as the client should not exceed three doses in 15 min. If the pain is not relieved after three doses, the client should seek emergency medical attention.

Taking this medication with 8 ounces of water is not necessary, as SL nitroglycerin tablets do not need to be swallowed or washed down with water. They should be dissolved under the tongue for optimal absorption.

Correct Answer is A

Explanation

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:

"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.

"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.
"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.

A. Thick, deformed toenails B. Edema C. Dependent rubor D. Hair loss

Correct Answer is B

Explanation

Edema is a common finding in clients who have chronic venous insufficiency, due to the impaired venous return and increased capillary pressure. The edema is usually worse at the end of the day and improves with elevation.

a. Thick, deformed toenails are more likely to be seen in clients who have fungal infections or peripheral arterial disease, not chronic venous insufficiency.

c. Dependent rubor is a sign of peripheral arterial disease, not chronic venous insufficiency. It is a reddish color of the lower extremities that occurs when they are lowered and disappears when they are elevated.

d. Hair loss is another sign of peripheral arterial disease, not chronic venous insufficiency. It is caused by the reduced blood supply to the hair follicles.
