Correct Answer: D

Rationale: The key management strategy for diabetic ketoacidosis (DKA) involves a comprehensive approach that includes administering insulin to lower blood glucose levels, monitoring blood glucose levels to ensure they are within the target range, and administering IV fluids to correct dehydration and electrolyte imbalances. Choosing 'All of the above' as the correct answer is the most appropriate because all three interventions are essential components of DKA management. Administering insulin alone without addressing fluid status and monitoring blood glucose could lead to complications. Similarly, solely focusing on IV fluids or blood glucose monitoring without insulin administration would not effectively manage DKA.

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: 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.

Correct Answer: A

Rationale: When managing care for a patient with a wound infection, administering prescribed antibiotics is crucial. Antibiotics are necessary to treat the infection and prevent it from worsening. While cleaning the wound with saline and applying a sterile dressing are important components of wound care, the primary treatment for a wound infection is antibiotics. Monitoring for signs of sepsis is also essential, but administering antibiotics promptly is the most critical step in managing a wound infection.

Correct Answer: B

Rationale: When assessing a client with a newly applied cast, the nurse should expect a capillary refill of approximately 2 seconds, as this indicates adequate circulation. A capillary refill longer than 3 seconds suggests impaired circulation, which is abnormal. Therefore, a capillary refill of 5 seconds is the finding the nurse should expect. Pitting edema and shortness of breath are not typically directly related to a newly applied cast and should not be expected findings in this scenario.
