Question 1 of 5
The nurse is caring for an elderly client who has congestive heart failure and is taking digoxin. The client should be monitored for which of the following signs of toxicity?
Correct Answer: A

Question 2 of 5
A low-sodium, low-cholesterol, weight-reducing diet is prescribed for an adult with heart disease. The nurse knows that he understands his diet when he chooses which of the following meals?
Correct Answer: A
Rationale: Baked skinless chicken and mashed potatoes are low in sodium and cholesterol, making them suitable for a heart-healthy diet. Stir-fried vegetables may contain high sodium sauces, tuna salad may include high-sodium dressings, and grilled steak is higher in cholesterol.
Question 3 of 5
The nurse checking the client's leg incision is aware that which is the most common blood vessel used in CABG surgery?
Correct Answer: A
Rationale: The saphenous vein is commonly used in CABG due to its accessibility and suitability for grafting.
Question 4 of 5
The nurse understands that the client's hesitation in going to the hospital is an example of which coping mechanism?
Correct Answer: C
Rationale: Denial involves minimizing or ignoring symptoms, such as attributing chest pain to muscle strain, delaying medical care.
Question 5 of 5
An adult who is admitted for a cardiac catheterization asks the nurse if she will be asleep during the cardiac catheterization. What is the best initial response for the nurse to make?
Correct Answer: B
Rationale: During cardiac catheterization, clients receive sedation but remain awake, as their cooperation may be needed. General anesthesia is not used, and pain is managed with sedation, not additional anesthetics. Asking 'why' may make the client defensive and does not provide the requested information.
