ATI RN Exit Exam Quizlet

Correct Answer: A

Rationale: Choice A is the correct answer because consuming a snack when the blood glucose level is below 70 mg/dL helps prevent hypoglycemia in clients with diabetes mellitus. Choice B is incorrect because taking insulin when blood glucose is high (above 200 mg/dL) helps manage hyperglycemia, not hypoglycemia. Choice C is incorrect as checking blood glucose levels once a week is insufficient for proper diabetes management, which typically requires more frequent monitoring. Choice D is incorrect because waiting for symptoms of hyperglycemia to take insulin can lead to uncontrolled blood glucose levels.

Correct Answer: A

Rationale: The best position for a patient with respiratory distress is the Semi-Fowler's position. This position promotes lung expansion and improves oxygenation by allowing the chest to expand more fully. The Trendelenburg position, where the patient's feet are higher than the head, is contraindicated in respiratory distress as it can increase pressure on the diaphragm and compromise breathing. The prone position, lying face down, may be beneficial in certain cases like acute respiratory distress syndrome but is not generally recommended for all patients in respiratory distress. The supine position, lying flat on the back, can worsen respiratory distress by causing the tongue to fall back and obstruct the airway.

Correct Answer: D

Rationale: Clients diagnosed with tuberculosis should be placed in a negative pressure room to prevent the spread of airborne pathogens. Option A is incorrect because administering isoniazid is a treatment for tuberculosis, not a preventive measure related to infection control. Option B is incorrect as droplet isolation is used for diseases transmitted through respiratory droplets, not airborne pathogens like tuberculosis. Option C is incorrect as wearing a surgical mask is not sufficient to prevent the spread of tuberculosis in healthcare settings; placing the client in a negative pressure room is the most effective measure.

Correct Answer: A

Rationale: The most important nursing intervention for a patient with a suspected pulmonary embolism is to administer anticoagulants. Anticoagulants help prevent further clot formation in the patient's blood vessels, reducing the risk of complications such as worsening of the pulmonary embolism or development of new clots. Administering oxygen (Choice B) may be necessary to support the patient's oxygenation, but anticoagulants take precedence as they target the underlying cause of the pulmonary embolism. Repositioning the patient (Choice C) and monitoring oxygen saturation (Choice D) are important aspects of patient care but are not the primary intervention for a suspected pulmonary embolism.

Correct Answer: C

Rationale: In a postoperative client, a urine output of 30 mL/hr is a concerning finding as it indicates oliguria, which may suggest dehydration or kidney impairment. Adequate urine output is essential for monitoring renal function and overall fluid status. A heart rate of 78/min is within the normal range for an adult. An oxygen saturation of 95% is acceptable and indicates adequate oxygenation. Serosanguineous wound drainage is expected in the early postoperative period and is not a cause for immediate concern unless it becomes excessive or changes character.
