Correct Answer: B

Rationale: The correct answer is to keep the home environment warm. Raynaud's disease causes vasospasm in response to cold, so maintaining a warm environment can help prevent attacks. Choices A, C, and D are incorrect. Increasing potassium intake, elevating legs when sitting, or reducing sodium intake are not specific to managing Raynaud's disease.

Correct Answer: C

Rationale: The correct answer is C: Restore the client's self-control. When managing a physically assaultive client, the nurse's responsibility is to help the client regain control over their actions and emotions. This is crucial in preventing harm to themselves and others. Restricting the client to the room (Choice A) may escalate the situation and is not a therapeutic approach. Placing the client under one-to-one supervision (Choice B) is important for safety but does not address the root cause of the behavior. Clearing the area of other clients (Choice D) is necessary for safety but does not directly address the client's self-control. Therefore, the priority in managing an assaultive client is to focus on restoring their self-control.

Correct Answer: A

Rationale: To administer a total of 300 mg daily (150 mg PO BID), the nurse should give 20 mL of the syrup. This is calculated by dividing the total daily dose (300 mg) by the concentration of the syrup (15 mg/mL), which equals 20 mL. Choice B (15 mL), C (25 mL), and D (10 mL) are incorrect because they do not accurately calculate the required volume of syrup needed to deliver the prescribed dose.

Correct Answer: B

Rationale: The correct instruction that the nurse should include is to rotate injection sites with each dose. This practice is essential to prevent tissue damage and ensure proper insulin absorption. Option A is incorrect because insulin should not be injected into the muscle, but rather into the subcutaneous tissue. Option C is incorrect as insulin should be stored in the refrigerator to maintain its effectiveness. Option D is incorrect as massaging the injection site after administration can lead to faster absorption and potentially hypoglycemia.

Correct Answer: A

Rationale: The correct answer is A: Electrolyte imbalance and dehydration. Diabetic ketoacidosis can lead to imbalances in electrolytes such as potassium, sodium, and chloride, as well as dehydration due to excess urination and vomiting. These complications should be managed promptly with appropriate fluids and insulin. Choices B, C, and D are incorrect. Hypoglycemia and increased urination are not typical complications of diabetic ketoacidosis; kidney failure and respiratory distress may occur in severe cases but are not the primary complications. Liver failure and hypertension are not directly associated with diabetic ketoacidosis.
