Correct Answer: A

Rationale: The correct answer is A because monitoring the client's temperature before, during, and after the transfusion allows the nurse to identify any changes or trends that may indicate a complication related to the blood transfusion. This comprehensive monitoring helps differentiate between a normal body response to cold blood infusion and a potential adverse reaction. Choice B is incorrect because documenting the client's temperature only after the transfusion may miss important changes during the process. Choice C is incorrect as the temperature of the blood before transfusion does not directly indicate the client's response to the chilled blood. Choice D is incorrect as comparing the client's temperature with the temperature of the blood alone does not provide a complete picture of the client's condition throughout the transfusion process.

Correct Answer: B

Rationale: The correct answer is B: maintain blood pressure control. After PTCA, the priority goal is to ensure stable hemodynamics. Maintaining blood pressure control is crucial to prevent complications such as bleeding or thrombosis. Choices A, C, and D are incorrect because preventing fluid volume deficit, decreasing myocardial contractility, and minimizing dyspnea are not immediate priorities post-PTCA. Oxygenation and hemodynamic stability take precedence over these concerns.

Correct Answer: A

Rationale: The correct answer is A because narcotics in high doses can depress the respiratory rate and cough reflex, which can be especially dangerous for a laryngectomy patient due to the risk of airway compromise. Low doses can provide pain relief without significant respiratory depression. Choices B and C are incorrect because narcotics typically do not increase respiratory tract secretions or cause stomal edema. Choice D is incorrect because while narcotics can potentially cause addiction, this is not the primary reason for giving low doses to laryngectomy patients.

Correct Answer: C

Rationale: The correct answer is C because it focuses on the client actively engaging in reducing tension, which is essential in managing anxiety. This outcome is measurable and client-centered. A: Verbalizing feelings is important, but it does not necessarily lead to reduction in anxiety. B: Not guessing prognosis is helpful, but it does not address the active management of anxiety. D: Stopping seeking information may not be beneficial as knowledge can empower the client in coping with the diagnosis.

Correct Answer: A

Rationale: Step 1: Pulmonary edema is caused by fluid accumulation in the lungs due to increased pressure in the pulmonary vasculature. Step 2: Decreased left ventricular pumping leads to congestive heart failure, causing increased pressure in pulmonary circulation. Step 3: This increased pressure forces fluid from the capillaries into the alveoli, causing pulmonary edema. Step 4: Increased left atrial contractility (B) would not directly lead to pulmonary edema. Step 5: Decreased right ventricular elasticity (C) and increased right atrial pressure (D) are not directly related to the pathophysiology of pulmonary edema. Summary: The correct answer is A because decreased left ventricular pumping directly contributes to the increased pressure in the pulmonary circulation that leads to pulmonary edema. Choices B, C, and D do not align with the primary underlying disorder of pulmonary edema.
