PN ATI Capstone Adult Medical-Surgical 1 Quiz

Correct Answer: B

Rationale: When using the ABC approach to client care, the nurse should identify that the priority intervention is administering oxygen. In this scenario, the client's oxygen saturation is only 91%, which is below the normal range of 95% and above. Oxygen is essential for adequate tissue perfusion and oxygenation of vital organs. Administering oxygen takes precedence over other interventions to ensure the client's physiological needs are met first. Choice A can be addressed after ensuring adequate oxygenation. Choice C is important for preventing postoperative complications but is not as urgent as addressing oxygen saturation. Choice D is a common postoperative intervention, but in this case, ensuring adequate oxygenation is the priority over IV fluid administration.

Correct Answer: C

Rationale: The correct information that the nurse should include in the teaching about a CPAP device is that it delivers a preset amount of airway pressure throughout the breathing cycle. This consistent positive airway pressure helps keep the airway open during both inspiration and expiration. Choice A is incorrect as CPAP does not deliver pressure only at the beginning of each breath. Choice B is incorrect because CPAP provides a constant level of pressure without continuous adjustments throughout the cycle. Choice D is incorrect as CPAP does not provide positive pressure at the end of each breath; instead, it maintains a continuous positive pressure.

Correct Answer: A

Rationale: The correct answer is A, Propofol. Propofol is a short-acting anesthetic medication commonly used to induce moderate sedation for procedures like a colonoscopy. This medication provides rapid onset and recovery, making it an ideal choice for such procedures. Choice B, Pancuronium, is a neuromuscular blocking agent used for muscle relaxation during surgery and would not be appropriate for sedation during a colonoscopy. Choice C, Promethazine, is an antihistamine used for nausea and motion sickness, not for anesthesia. Choice D, Pentoxifylline, is a medication used to improve blood flow in patients with circulation problems and is not indicated for anesthesia during a colonoscopy.

Correct Answer: B

Rationale: The correct answer is B because shortness of breath is an indication of transplant rejection, along with other manifestations like fatigue, edema, bradycardia, and hypotension. Choice A is incorrect because immunosuppressant medications are usually taken for life to prevent rejection. Choice C is incorrect as the surgical site may take longer to heal fully. Choice D is incorrect as the initiation of exercise post-heart transplant should be gradual and individualized based on the client's condition.

Correct Answer: C

Rationale: The correct answer is C because the client should have a quick-acting source of 15 g of carbohydrates to treat hypoglycemic episodes, such as 4 oz of regular soda. Choice A is incorrect because while exercise can help manage blood sugar levels, it can also increase the risk of hypoglycemia if not properly managed. Choice B is incorrect as skipping insulin when not eating can lead to hyperglycemia, not prevent hypoglycemia. Choice D is incorrect because certain oral diabetic medications can indeed cause hypoglycemia, not just insulin.
