Pharmacology and the Nursing Process 9th Edition Test Bank

Correct Answer: A

Rationale: The correct answer is A: A hemolytic reaction to mismatched blood. Chills, dyspnea, and urticaria are indicative of a hemolytic transfusion reaction, which occurs when the recipient's immune system attacks the donor's red blood cells. This can lead to various symptoms, including fever, chills, difficulty breathing, and hives. This type of reaction is most commonly seen with mismatched blood types. Option B (A hemolytic reaction to Rh-incompatible blood) is incorrect because Rh incompatibility typically leads to hemolytic disease of the newborn, not an immediate transfusion reaction. Option C (A hemolytic allergic reaction caused by bacterial contamination of donor blood) is incorrect as bacterial contamination would present with symptoms such as fever and sepsis, not chills, dyspnea, and urticaria. Option D (None of the above) is incorrect as the symptoms presented align with a hemolytic transfusion reaction.

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: 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.

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: 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.
