Correct Answer: B

Rationale: The correct answer is B. Nursing the baby frequently helps prevent engorgement and discomfort in breastfeeding mothers. Choice A is incorrect because tight-fitting bras can lead to clogged milk ducts and worsen discomfort. Choice C may lead to oversupply issues and is not necessary unless there is a specific indication. Choice D is incorrect as avoiding nursing for extended periods can lead to engorgement and decreased milk supply.

Correct Answer: B

Rationale: The correct first step in preparing a blood transfusion is to verify the client's blood type before starting the transfusion. This step is crucial to ensure compatibility and prevent adverse reactions. Administering the blood via IV push (Choice A) is incorrect as it skips the essential step of verifying the blood type. Warming the blood to body temperature (Choice C) is important but comes after verifying the blood type. Administering diuretics (Choice D) is not part of the preparation process for a blood transfusion.

Correct Answer: B

Rationale: The correct answer is B: Fever. Fever in a postoperative client can indicate an infection, which is a serious complication and should be reported immediately to the provider for further evaluation and management. Clear lung sounds (Choice A) are a positive finding indicating normal respiratory function. Pain in the operative leg (Choice C) is expected postoperatively and should be managed with appropriate pain relief measures. Capillary refill of 2 seconds (Choice D) is within the normal range (less than 3 seconds) and is not a concerning finding postoperatively.

Correct Answer: A

Rationale: The most appropriate intervention for a client with left-leg weakness learning to use a cane is to maintain two points of support on the floor at all times. This ensures stability and helps distribute weight evenly between the legs, reducing the risk of falls. Using the cane on the weak side of the body (Choice B) may not provide adequate support. Advancing the cane and the strong leg simultaneously (Choice C) can lead to imbalance and increases the risk of falls. Advancing the cane too far with each step (Choice D) can also compromise balance and stability.

Correct Answer: A

Rationale: The correct adverse effect that the nurse should include in the teaching is fatigue. Fatigue is a common side effect of radiation therapy, particularly with prolonged treatment. Constipation, hair loss, and weight gain are not typically associated with radiation therapy for breast cancer, making them incorrect choices. Fatigue can significantly impact a patient's quality of life during treatment and should be addressed proactively by healthcare providers.
