A nurse is caring for a client who has had a myocardial infarction. Upon his first visit to cardiac rehabilitation, he tells the nurse that he doesn't understand why he needs to be there because there is nothing more to do, as the damage is done. Which of the following is the correct nursing response?

"It's not unusual to feel that way at first, but once you learn the routine, you'll enjoy it."

"Exercise is good for you and good for your heart."

"Cardiac rehabilitation cannot undo the damage to your heart but it can help you get back to your previous level of activity safely."

"Your doctor is the expert here, and I'm sure he would only recommend what is best for you."

Answer and Explanation

The Correct Answer is C

Choice A reason:

This statement is incorrect because it trivializes the patient's concerns and implies that enjoyment is the primary goal, which is not the case. The main purpose of cardiac rehabilitation is to improve health outcomes, not just to make the routine enjoyable.

Choice B reason:

While exercise is beneficial for heart health, this statement is too general and does not address the specific benefits of cardiac rehabilitation for someone who has had a myocardial infarction.

The correct answer is C:

"Cardiac rehabilitation cannot undo the damage to your heart but it can help you get back to your previous level of activity safely." Cardiac rehabilitation is crucial for patients who have experienced a myocardial infarction. It provides a structured program that includes exercise, education, and support to help patients improve their cardiovascular health and prevent future cardiac events.

Choice D reason:

Deferring to the doctor's expertise does not educate the patient about the benefits of cardiac rehabilitation. It's important for patients to understand why they are participating in the program.

Correct Answer is ["24 mL\/hr"]

Explanation

To calculate the infusion rate, use the formula:

(rate in mL/hr) = (desired dose in units/hr) / (available dose in units/mL)

In this case, the desired dose is 1,200 units/hr and the available dose is 25,000 units / 500 mL = 50 units/mL. Therefore,

(rate in mL/hr) = (1,200 units/hr) / (50 units/mL) = 24 mL/hr

Round the answer to the nearest tenth/whole number and use a leading zero if it applies. Do not use a trailing zero because it could be misread as a decimal point. Therefore, the nurse should set the IV pump to deliver 24 mL/hr.

A. "A headache is an indication of an allergy to the medication." B. "A headache indicates tolerance to the medication." C. "A headache is likely due to the anxiety about the chest pain." D. "A headache is an expected adverse eﬀect of the medication."

Correct Answer is D

Explanation

A headache is a common and expected adverse eﬀect of nitroglycerin, due to its vasodilating action. The client can take an over-the-counter analgesic to relieve the headache, unless contraindicated.

"A headache is an indication of an allergy to the medication." is not correct, as a headache is not a sign of an allergic reaction to nitroglycerin. An allergic reaction would manifest as rash, itching, swelling, or difficulty breathing.

"A headache indicates tolerance to the medication." is not accurate, as a headache does not indicate tolerance to nitroglycerin. Tolerance would manifest as reduced or absent relief from anginal pain.

"A headache is likely due to the anxiety about the chest pain." is not plausible, as a headache is not likely due to the anxiety about the chest pain. Anxiety would manifest as nervousness, restlessness, palpitations, or sweating.
