Correct Answer: A

Rationale: The correct answer is A. Instructing the client to remain still once the gel pads are attached is crucial to obtaining accurate ECG readings. Choice B is incorrect as electrodes are typically placed on the chest, not the breast. Choice C is incorrect because the client should lie flat during an ECG, not sit up. Choice D is incorrect because the client should breathe normally, rather than holding their breath, throughout the procedure.

Correct Answer: C

Rationale: Cheddar cheese is indeed a good source of protein, providing a significant amount per serving. While chicken and tofu are also high in protein, cheddar cheese can be a beneficial source, especially for individuals looking for non-meat options. Almonds, while nutritious, are not as high in protein compared to the other options listed.

Correct Answer: A

Rationale: Choice A is the correct answer because lifting more than 35 pounds without assistance can cause injury, so getting help is crucial for proper body mechanics. Choice B is incorrect as twisting at the waist can lead to back injuries. Choice C is incorrect as holding objects closer to the body, not 1 ft away, is recommended to reduce strain. Choice D is incorrect as rolling shoulders forward can increase strain on the back instead of reducing it.

Correct Answer: B

Rationale: The correct answer is B: Decreased anginal pain. Verapamil is a calcium channel blocker used to relieve angina by reducing myocardial oxygen demand. Monitoring for decreased anginal pain is essential as it indicates a therapeutic response to the medication. Choices A, C, and D are incorrect as verapamil's primary goal in this context is not to decrease blood pressure, heart rate, or anxiety.

Correct Answer: C

Rationale: The priority action for the nurse is to determine the reasons why the client is refusing to use the incentive spirometer. By understanding the client's concerns or issues, the nurse can address them effectively, provide education or support, and encourage the client to comply with the necessary postoperative care. This approach fosters a patient-centered care environment. Demonstrating how to use the spirometer (Choice A) may be important but is not the priority at this moment. Setting a realistic postoperative goal (Choice B) is relevant but not as immediate as understanding the client's refusal. Requesting a respiratory therapist (Choice D) can be considered later if needed, but the nurse's initial focus should be on understanding the client's perspective.
