Correct Answer: C

Rationale: The correct answer is C: Break the task down into simple steps. This response is the best because it helps the patient by breaking down the task into manageable parts, making it less overwhelming and more achievable. By providing clear and simple steps, the patient can focus on one aspect at a time, reducing frustration and increasing the likelihood of successful completion. Choice A is incorrect because performing the task for the patient does not promote independence or skill development. Choice B is incorrect as it dismisses the patient's feelings of frustration without offering a solution. Choice D is incorrect because having another patient demonstrate may not address the specific needs and abilities of the recovering stroke patient.

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: A

Rationale: The correct answer is A: Moisture replacement. Sjogren's syndrome is an autoimmune disorder that primarily affects the moisture-producing glands, leading to dryness in the eyes, mouth, and other mucous membranes. Nursing care should focus on managing these symptoms by providing moisture replacement through artificial tears, lubricating eye drops, and hydrating mouthwashes. This helps prevent complications such as corneal damage and dental issues. Nutritional supplementation (B) may be needed if there are difficulties in eating due to dry mouth, but it is not the primary focus. Electrolyte balance (C) and arrhythmia management (D) are not directly related to the symptoms of Sjogren's syndrome and are therefore not the main priorities in nursing care for this condition.

Correct Answer: C

Rationale: The correct answer is C: 3.8 mL. To calculate the volume needed, first determine the concentration of the solution after reconstitution: 2.4 million units / 5,000,000 units = 0.48. Next, divide the desired dose by the concentration: 2.4 million units / 0.48 = 5 mL. Since the instructions state to dilute with 8 mL of sterile water, the total volume will be 13 mL. To find the volume of the powder to draw up, subtract the water volume from the total volume: 13 mL - 8 mL = 5 mL. Therefore, the nurse should draw up 5 mL of the reconstituted solution, which is equivalent to 3.8 mL of powder for injection. Incorrect choices: A, B, and D are incorrect because they do not consider the dilution factor of adding sterile water to the powder for injection. Option A is less than the

Correct Answer: C

Rationale: Step-by-step rationale for why choice C is correct: 1. The lab value of K at 3.2 mEq/L indicates hypokalemia. 2. Digitalis can worsen hypokalemia and lead to toxicity. 3. Avoiding foods rich in potassium will prevent further lowering of potassium levels. 4. This intervention helps prevent potential digitalis toxicity in the client. Summary of why the other choices are incorrect: A. Stopping digitalis therapy abruptly can lead to rebound effects and worsen the condition. B. Trousseau's and Chvostek's signs are not relevant to the client's current lab values. D. While observing for digitalis toxicity is important, addressing the low potassium level is a more immediate concern in this scenario.
