PN ATI Comprehensive Predictor

Correct Answer: D

Rationale: The correct answer is D: Consumption of contaminated food. Hepatitis A is primarily transmitted through the ingestion of contaminated food or water. Airborne droplets and sexual contact are not common modes of transmission for hepatitis A. While contact with contaminated surfaces can play a role in the spread of some infections, hepatitis A is not typically transmitted through this route.

Correct Answer: C

Rationale: In the early stages of hypovolemic shock, the body initiates compensatory mechanisms to maintain perfusion. One of these mechanisms is an increased respiratory rate to improve oxygen delivery. This helps to offset the decreased circulating blood volume. A heart rate of 60/min (choice A) is not expected in hypovolemic shock; instead, tachycardia is a common finding due to the body's attempt to maintain cardiac output. Increased urinary output (choice B) is not typically seen in hypovolemic shock as the body tries to conserve fluid. Hypothermia (choice D) is usually a late sign of shock when the body's compensatory mechanisms are failing, and perfusion is severely compromised.

Correct Answer: C

Rationale: Identifying environmental hazards in the client's home is the priority during the initial visit with an older adult living alone. This action is crucial to prevent accidents, falls, and ensure the client's safety. While educating the client about their medical diagnosis, referring them to a meal delivery program, and arranging transportation for follow-up appointments are essential, addressing environmental hazards takes precedence as it directly impacts the client's immediate safety and well-being.

Correct Answer: C

Rationale: Choice C is the correct answer. During a colonoscopy, clients are typically sedated, so they do not feel any pain during the procedure. Choices A, B, and D are incorrect. Clients are usually required to stop eating and drinking at least 24 hours before a colonoscopy, and there are specific dietary restrictions that need to be followed before the procedure to ensure a successful examination.

Correct Answer: A

Rationale: The correct answer is A: Hypoventilation and lung disease. Respiratory acidosis occurs when there is an accumulation of CO2 in the body due to inadequate ventilation. Hypoventilation, which reduces the elimination of CO2, and lung diseases that impair gas exchange are the primary causes. Choice B is incorrect because hyperventilation, not hypoventilation, leads to respiratory alkalosis, not acidosis. Choice C is incorrect because increased oxygen saturation and tachypnea do not directly cause respiratory acidosis. Choice D is incorrect as dehydration and hypoxia do not typically lead to respiratory acidosis.
