Correct Answer: A

Rationale: The correct answer is A: 'I can concentrate best in the morning.' Readiness to learn is indicated by the client's ability to focus and concentrate, as mentioned in the question. Choice B, 'I feel anxious about learning the process,' indicates apprehension and may hinder the learning process. Choice C, 'I have a lot of questions about insulin,' shows interest but does not directly indicate readiness to learn. Choice D, 'I am not sure if I can manage this at home,' reflects uncertainty and lack of confidence, which may suggest the client is not fully prepared to learn.

Correct Answer: C

Rationale: Choice C is the correct answer because it demonstrates that the client understands the importance of communicating with the nurse if the pain persists while using the PCA device. This is crucial as it ensures proper pain management and monitoring. Choices A and B are incorrect because delaying the use of the device until necessary or being cautious about pushing the button too much do not necessarily reflect understanding of using the PCA device effectively. Choice D is incorrect as having someone else, like an adult child, push the dose button goes against the principle of the client self-administering the medication through the PCA device.

Correct Answer: A

Rationale: Placing a pillow under the patient's lower legs when in the prone position is essential to allow dorsiflexion of the ankles and some knee flexion, which promote relaxation. This position also helps in maintaining proper alignment of the spine. Options B, C, and D are incorrect because turning the head, positioning legs flat against the bed, and raising the head of the bed to 45 degrees are not appropriate actions for a patient in the prone position. Turning the head to one side with a large, soft pillow is commonly done for patients in the supine position to maintain proper alignment and airway patency. Positioning legs flat against the bed is more suitable for a patient in a supine or semi-fowler's position. Raising the head of the bed to 45 degrees is typically done for patients who need semi-fowler's positioning for respiratory support or to prevent aspiration.

Correct Answer: A

Rationale: The correct technique for logrolling involves at least three to four people to ensure the safety and proper alignment of the patient's spine. Logrolling requires coordinated effort from multiple individuals to prevent twisting or bending of the spine, hence option A is correct. Option B is incorrect as patients with spinal cord injuries should not be instructed to reach for the opposite side rail due to the risk of causing harm. Option C is incorrect as moving the bottom part of the patient's torso first could lead to spinal misalignment. Option D is incorrect as pillows should be used for support and comfort after the patient has been successfully turned, not before.

Correct Answer: A

Rationale: Correct! Written consent is required for procedures that carry significant risks, such as blood transfusions, to ensure the client's informed consent and understanding of the procedure. In this case, a transfusion of packed red blood cells is an invasive procedure that carries risks, making it essential to have the client's written consent. Choices B, C, and D do not typically require written consent as routine physical examinations, minor surgical procedures without anesthesia, and new medication prescriptions do not carry the same level of risk and complexity as a blood transfusion.
