A nurse is caring for a client who has a deep vein thrombosis and is prescribed heparin by continuous IV infusion at 1,200 units/hr. Available is heparin 25,000 units in 500 mL DSW. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)

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.

Swallowing the capsules whole is the correct way to take nitroglycerin oral, sustained-release capsules, as they are designed to release the medication slowly and steadily over time. The client should not crush, chew, or open the capsules, as this can alter the absorption and effectiveness of the medication.

Taking 1 capsule at the onset of anginal pain is not appropriate, as nitroglycerin oral, sustained-release capsules are not meant for acute episodes of angina, but for long-term prevention and management. The client should use a fast-acting form of nitroglycerin, such as sublingual tablets or spray, to relieve anginal pain.

Taking the medication with meals is not necessary, as nitroglycerin oral, sustained-release capsules can be taken with or without food. However, the client should take the medication at regular intervals and around the same time each day.

Stopping taking the medication if side effects are troublesome is not advisable, as nitroglycerin oral, sustained-release capsules can cause withdrawal symptoms and rebound angina if discontinued abruptly. The client should consult with the provider before stopping or changing the dose of the medication. The client should also report any severe or persistent side effects, such as headache, dizziness, hypotension, or tachycardia.
