Correct Answer: A

Rationale: The correct answer is A: Immobility and poor nutrition are significant risk factors for pressure ulcers. Immobility leads to prolonged pressure on certain body areas, increasing the risk of tissue damage. Poor nutrition can impair skin integrity and the body's ability to heal. Prevention strategies include frequent turning and repositioning to relieve pressure points. Choice B is incorrect because increased mobility actually reduces the risk of pressure ulcers. Choice C is incorrect as excess moisture can contribute to skin breakdown, but it is not a primary risk factor. Choice D is incorrect as frequent turning and repositioning are part of the prevention measures, not risk factors.

Correct Answer: A

Rationale: The correct answer is A: Lamb. Lamb is high in saturated fat, which is linked to an increased risk of developing cancer. Choice B (Poultry) is a lean protein source and is not associated with an increased cancer risk. Choice C (Tuna) is a good source of omega-3 fatty acids, which have anti-inflammatory properties that may reduce cancer risk. Choice D (Beef) is also high in saturated fat like lamb, making it a poor choice for cancer prevention.

Correct Answer: A

Rationale: The correct answer is A: "Left-sided: Pulmonary congestion; Right-sided: Systemic edema." Left-sided heart failure primarily affects the lungs, leading to pulmonary congestion, which manifests as symptoms like shortness of breath and cough. On the other hand, right-sided heart failure causes systemic congestion and edema, often presenting as swelling in the legs and abdomen due to fluid retention. Choice B is incorrect because it swaps the features of left-sided and right-sided heart failure. Choice C is incorrect as it also incorrectly switches the characteristics of the two types of heart failure. Choice D is incorrect because it inaccurately associates left-sided heart failure with pulmonary congestion and right-sided heart failure with heart failure itself, which is not a distinguishing feature.

Correct Answer: C

Rationale: The correct intervention for a client at risk for pressure ulcers is to turn and reposition the client every 2 hours. This helps relieve pressure on bony prominences, improving circulation and reducing the risk of pressure ulcer development. Applying heat to the affected area (Choice A) can increase the risk of skin breakdown. Placing the client in a prone position (Choice B) can also increase pressure on certain areas, leading to pressure ulcers. Providing the client with a bedpan every 4 hours (Choice D) is not directly related to preventing pressure ulcers.

Correct Answer: B

Rationale: The correct answer is B. Applying antiembolic stockings before the client gets out of bed is crucial as it helps prevent venous stasis and clot formation. Choice A is incorrect because stockings should be applied before the client gets out of bed. Choice C is incorrect as using lotion under the stocking can cause the stocking to slip. Choice D is incorrect because the stocking should be smooth and not bunched to prevent pressure points.
