Correct Answer: B

Rationale: The nurse should address the client's lack of understanding regarding the need for surgery first. Ensuring that the client comprehends the rationale for the procedure is essential for informed consent. Choices A, C, and D, while important, do not directly impact the client's understanding of the necessity of the surgery and can be addressed after clarifying the reason for the procedure.

Correct Answer: A

Rationale: When a client is using a nasal cannula for oxygen therapy, the areas prone to skin damage are the tops of the ears and around the nostrils. The pressure exerted by the cannula on these areas can lead to skin breakdown, so it is important for the nurse to observe these sites for any signs of damage. The correct answer is 'Tops of the ears.' Choices 'Bridge of the nose' and 'Over the cheeks' are not typically areas where skin damage related to the cannula would occur, making them incorrect choices.

Correct Answer: D

Rationale: A fever of 101.5°F (38.6°C) in a client undergoing chemotherapy is a significant finding that may indicate an underlying infection, which can be life-threatening due to the client's compromised immune system. Prompt reporting and intervention are crucial to prevent complications. Mild nausea, hair loss, and increased fatigue are common side effects of chemotherapy and are expected findings that do not typically require immediate reporting unless they are severe or significantly impacting the client's well-being. Therefore, the LPN/LVN should prioritize reporting the fever over the other options.

Correct Answer: C

Rationale: The Z-track method is used to minimize tissue irritation by sealing the medication in the muscle. This technique helps prevent leakage of the medication into subcutaneous tissue, reducing the risk of irritation and staining at the injection site. Option A about decreasing the risk of injecting medication into a blood vessel is not correct as the primary purpose of the Z-track method is to prevent tissue irritation. Option B stating it delays medication absorption is incorrect as the Z-track method does not affect the rate of medication absorption. Option D mentioning it accelerates medication excretion is incorrect as the Z-track method does not impact medication excretion but rather focuses on minimizing tissue irritation.

Correct Answer: A

Rationale: Choice A is correct because performing ankle and knee exercises every hour helps prevent contractures and other adverse effects of immobility. Contractures are a common complication of immobility, and range of motion (ROM) exercises can help maintain joint flexibility and prevent contractures. This statement indicates an understanding of the teaching provided by the healthcare provider. Choices B, C, and D are incorrect. Holding the breath when rising from a sitting position can increase the risk of orthostatic hypotension, not reduce adverse effects of immobility. Removing antiembolic stockings while in bed can compromise their effectiveness in preventing deep vein thrombosis (DVT), which is not a measure to reduce immobility-related complications. Having a partner help change positions every 4 hours may not be frequent enough to prevent immobility-related complications effectively; changing positions more frequently is usually recommended to prevent issues like pressure ulcers and muscle stiffness.
