Correct Answer: A

Rationale: The correct answer is A because maintaining consistency in the order of drawing different types of insulin into the syringe helps prevent medication errors. When mixing insulins, drawing them in the same sequence ensures the correct dose and prevents contamination. Explanation: A: Following the same order ensures accurate dosing and minimizes the risk of mixing up insulins. B: Shaking the vial can cause air bubbles which can affect the accuracy of the dose. C: Storing insulin in the freezer can damage the medication and alter its effectiveness. D: Cloudiness in intermediate-acting insulin is normal and does not indicate it should be discarded.

Correct Answer: B

Rationale: The correct answer is B: “Rotate injection sites within the same anatomic region, not among different regions.” This instruction is important to prevent lipodystrophy and ensure consistent insulin absorption. Rotating sites within the same region helps maintain consistent insulin absorption rates and reduces the risk of developing scar tissue or fatty deposits. Injecting into healthy tissue with large blood vessels and nerves (choice A) can lead to inconsistent absorption. Administering insulin into areas of scar tissue or hypotrophy (choice C) can also disrupt absorption. Injecting into sites above muscles planned for exercise (choice D) can lead to unpredictable insulin absorption. Rotation within the same region optimizes insulin delivery and prevents complications.

Correct Answer: B

Rationale: The correct answer is B: IV is the route of choice for rapid administration. IV route allows for quick onset of action, crucial in acutely fluid-overloaded patients needing immediate diuresis. Option A is incorrect as furosemide can be given orally too. Option C is less relevant in this urgent situation where speed is key. Option D is also incorrect as the side effects are not determined by route of administration.

Correct Answer: B

Rationale: The correct answer is B: An improvement of the weakness. Edrophonium is a short-acting cholinesterase inhibitor that helps differentiate between myasthenic and cholinergic crises in myasthenia gravis. In cholinergic crisis, there is an overdose of cholinesterase inhibitors leading to excessive acetylcholine at the neuromuscular junction, causing muscle weakness. Administering edrophonium will temporarily improve muscle weakness in cholinergic crisis due to the increased availability of acetylcholine. The other choices are incorrect because: A: No change suggests the client is not in cholinergic crisis. C: Complaints of muscle spasms are more indicative of myasthenic crisis. D: A temporary worsening of the condition is not expected in cholinergic crisis.

Correct Answer: D

Rationale: The correct answer is D because assessing for localized ischemia involves evaluating multiple factors. A: Assessing color and temperature helps determine perfusion. B: Checking capillary refill assesses circulation. C: Evaluating pulse rate indicates cardiac output. Doing all of the above provides a comprehensive assessment of arterial flow and potential ischemia. Other choices are incorrect as they do not cover all aspects necessary for a thorough assessment.
