A nurse is caring for a client who is receiving heparin by continuous IV infusion for treatment of venous thrombosis. Which of the following laboratory values should the nurse monitor for in order to titrate the heparin dose?

The client statement that indicates an understanding of the teaching is: "The medication can cause drowsiness."

Promethazine is an antihistamine medication commonly used to treat various conditions, such as allergies, motion sickness, and nausea. One of the most common side effects of promethazine is drowsiness or sedation. It has a significant sedative effect, and it is often used to induce sleep or manage insomnia in some cases.

Let's go through the other options:

A. "This medication can cause diarrhea": Diarrhea is not a common side effect of promethazine. While promethazine can cause certain gastrointestinal side effects like constipation or upset stomach, diarrhea is not typically associated with its use.

B. "The medication can cause increased salivation": Increased salivation is not a common side effect of promethazine. While some antihistamines can cause dry mouth, which is the opposite of increased salivation, promethazine does not usually cause excessive salivation.

C. "This medication can cause pupil constriction": Pupil constriction (miosis) is a potential side effect of some medications, but it is not commonly associated with promethazine. Promethazine is more likely to cause pupil dilation (mydriasis) rather than constriction.

When planning care for a client who had a myocardial infarction and is receiving thrombolytic therapy with an IV infusion of alteplase, the nurse should include the intervention of monitoring for changes in the client's level of consciousness.

Alteplase is a thrombolytic medication used to break down blood clots in certain medical emergencies, such as acute myocardial infarction (heart attack) or ischemic stroke. One of the potential complications of thrombolytic therapy, including alteplase, is bleeding. The medication's action of breaking down blood clots can also affect the body's natural clotting mechanisms, increasing the risk of bleeding.

Bleeding in the brain is a severe and potentially life-threatening complication associated with thrombolytic therapy. Therefore, it is essential for the nurse to closely monitor the client for any signs of intracranial bleeding, such as changes in the level of consciousness, confusion, severe headache, slurred speech, or weakness on one side of the body.

Let's go through the other options:

A. Administer aspirin instead of acetaminophen for fever: While aspirin is commonly used in the management of myocardial infarction, it is not specifically indicated for fever. Acetaminophen is the preferred antipyretic medication for fever management in most cases, and it does not interfere with the action of thrombolytic therapy.

B. Ambulate the client as often as tolerated: While early ambulation is beneficial for clients with myocardial infarction, it may not be appropriate during thrombolytic therapy. Thrombolytic therapy carries an increased risk of bleeding, and ambulation may be limited or contraindicated during the treatment period, depending on the client's overall condition and bleeding risk.

C. Administer a sodium phosphate enema for constipation: The administration of a sodium phosphate enema is not a specific intervention related to thrombolytic therapy or myocardial infarction. Bowel management is important for client comfort and overall well-being, but it is not a priority intervention in the immediate care of a client undergoing thrombolytic therapy.
