What are the risk factors for the development of pressure ulcers, and how can they be prevented?

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: Corrected DVT management involves administering anticoagulants to prevent clot growth and monitoring for signs of bleeding. Elevating the limb and administering pain relief (Choice B) may help alleviate symptoms but do not address the underlying issue of preventing clot progression. Restricting mobility and applying warm compress (Choice C) could potentially dislodge the clot and worsen the condition. Administering IV fluids and providing bed rest (Choice D) are not primary interventions for managing DVT.

Correct Answer: A

Rationale: In acute renal failure, it is crucial to monitor urine output to assess kidney function and fluid balance. Administering diuretics helps manage fluid levels by promoting urine production. Choice B is incorrect because administering IV fluids can worsen fluid overload in renal failure patients, and restricting potassium intake is not typically the initial approach. Choice C is not the primary intervention but is important for long-term management. Choice D is incorrect as administering potassium can be dangerous in renal failure, and restricting fluids can lead to dehydration.

Correct Answer: A

Rationale: The correct signs of hypovolemic shock are a rapid pulse and low blood pressure. Administering IV fluids helps to restore circulating volume, which is essential in managing hypovolemic shock. Choice B is incorrect because cold extremities and rapid breathing are not typical signs of hypovolemic shock. Choice C is incorrect as administering diuretics would further decrease circulating volume, worsening the condition. Choice D is incorrect as administering vasopressors may further compromise perfusion in hypovolemic shock.

Correct Answer: A

Rationale: The correct answer is A. High cholesterol and hypertension are significant risk factors for stroke. Regular exercise is an effective way to prevent stroke by managing these risk factors. Choice B is incorrect as while obesity and smoking are risk factors, preventing stroke through medication and weight loss is not the primary method. Choice C is incorrect as diabetes and alcohol consumption are risk factors, but preventing stroke through regular checkups is not as direct as managing cholesterol and hypertension. Choice D is incorrect as lack of exercise and a poor diet are indeed risk factors, but the prevention of stroke through lifestyle changes needs to specifically address high cholesterol and hypertension.
