Correct Answer: B

Rationale: The correct answer is to instruct the client to step up with the unaffected leg first. This action is crucial as it ensures proper balance and safety when ascending stairs with crutches. By stepping up with the unaffected leg first, the client can maintain stability and reduce the risk of falls. Choices A, C, and D are incorrect. Moving both crutches up first (Choice A) may lead to imbalance and difficulty in weight distribution. Leaning forward on the crutches before stepping up (Choice C) can compromise the client's stability and increase the risk of falling. While holding onto the handrail for support (Choice D) is important, stepping up with the unaffected leg first takes precedence to establish a secure and safe movement up the stairs.

Correct Answer: B

Rationale: Performing a wound culture before applying ointment is crucial when providing wound care for a client with a pressure ulcer. This step helps identify the presence of any infection, allowing for appropriate treatment. Choice A is incorrect because covering the wound with a dry, sterile dressing may not address potential infections. Choice C is incorrect as cleansing the wound with alcohol can be too harsh and drying to the surrounding skin. Choice D is incorrect because covering the wound with a wet-to-dry dressing is not typically recommended for pressure ulcers, as it can cause trauma to the wound bed during removal.

Correct Answer: B

Rationale: The correct lifestyle change that should be emphasized for a client with hypertension is to limit the intake of high-fat foods. High-fat foods can contribute to high blood pressure, so reducing their consumption is important in managing hypertension. Choice A is incorrect because increasing intake of sodium-rich foods can worsen hypertension due to their effect on blood pressure. Choice C is incorrect as caffeinated beverages can also elevate blood pressure. Choice D is incorrect because while high-protein foods can be beneficial, they do not directly lower blood pressure like reducing high-fat foods would.

Correct Answer: B

Rationale: The correct answer is to consult with a dietitian to create a high-protein diet. A serum albumin level of 3 g/dL indicates hypoalbuminemia, which can impair wound healing. Consulting with a dietitian to optimize the client's protein intake is crucial in promoting wound healing for pressure ulcers. Increasing the protein intake in the diet (Choice A) may not be sufficient without proper guidance from a dietitian. Increasing the IV fluid infusion rate (Choice C) is not directly related to addressing the protein deficiency. Administering a protein supplement (Choice D) should be guided by a healthcare professional's recommendation after consulting with a dietitian.

Correct Answer: B

Rationale: The correct instruction the nurse should reinforce with the client undergoing radiation therapy is to avoid using perfumed lotions. This is essential to reduce the risk of skin irritation, as perfumed lotions can exacerbate skin reactions during radiation therapy. Applying sunscreen before going outside is generally a good practice but not specifically related to radiation therapy. Massaging the area daily is contraindicated during radiation therapy as it can further irritate the skin. Taking vitamin supplements with food is important for overall health but is not a specific instruction related to radiation therapy.
