The nurse and unlicensed assistive personnel (UAP) on the telemetry unit are caring for four clients. Which nursing action can be delegated to the UAP?

The best response by the nurse would be to explain that no food or drink is allowed for 4 hours before the stress test.

The reason for this restriction is that consuming food or drink can affect the accuracy of the cardiac stress test results. Eating or drinking can increase heart rate and blood pressure, potentially altering the test's interpretation. It is important for the client to have an empty stomach to ensure accurate test results.

Let's review the other options and explain why they are not the best responses:

Asking the client's visitor to bring some coffee from the cafeteria for the client: This option goes against the restriction of no food or drink before the stress test. It is important to adhere to the guidelines provided to ensure accurate test results.

Making up a small breakfast tray from what is available on the unit: Similarly, providing breakfast to the client goes against the restriction of no food before the stress test. The client should have an empty stomach for the test.

Offering hot tea or coffee only: While hot tea or coffee might be tempting for the client, it still violates the requirement of no food or drink before the stress test. The client should only be allowed to consume water during the fasting period.

Monitoring a client after a transesophageal echocardiogram involves observing the client for any immediate post-procedure complications or adverse reactions. This may include assessing vital signs, monitoring for signs of bleeding or infection, and reporting any concerning symptoms or changes in the client's condition to the nurse.

Checking the client's catheter site after a coronary angiogram requires assessing the site for bleeding, hematoma, or signs of infection. This task involves more complex assessment skills and would typically be performed by the nurse.

Teaching a patient about exercise electrocardiography involves providing education on the purpose of the test, the procedure itself, and any preparation or precautions the patient needs to take. This task requires specialized knowledge and is best performed by the nurse who can address the patient's specific questions and concerns.

Attaching ECG monitoring electrodes after a patient bathes requires technical knowledge and skill in properly placing the electrodes and ensuring accurate ECG readings. This task also falls within the scope of the nurse's responsibilities.

Delegation should be based on the UAP's skill set, training, and the complexity of the task. While the UAP can provide valuable support in monitoring a client after a transesophageal echocardiogram, the other tasks mentioned require the expertise and knowledge of a nurse.
