PN ATI Comprehensive Predictor

Correct Answer: B

Rationale: The priority for a client with dehydration is to monitor electrolyte levels to prevent imbalances. Dehydration can lead to electrolyte disturbances, which can have serious consequences. Administering antiemetics (Choice A) may help with nausea but does not address the root cause of dehydration. Administering oral rehydration solutions (Choice C) can be beneficial, but monitoring electrolyte levels is crucial in managing dehydration. Administering intravenous fluids (Choice D) is important in severe cases of dehydration, but monitoring electrolytes should come first to assess the extent of the imbalance and guide fluid replacement therapy effectively.

Correct Answer: A

Rationale: Corrected Rationale: Untreated fluid overload can lead to complications such as pulmonary edema and congestive heart failure. Pulmonary edema occurs when excess fluid accumulates in the lungs, leading to difficulty breathing and potentially life-threatening respiratory distress. Congestive heart failure can result from the heart's inability to pump effectively due to the excess fluid volume, leading to symptoms such as fatigue, shortness of breath, and fluid retention. Choices B, C, and D are incorrect because hypertension, liver failure, pulmonary embolism, and dehydration are not the primary complications directly associated with untreated fluid overload.

Correct Answer: B

Rationale: Using a bed exit alarm is the best intervention to prevent injury in a client with dementia at risk of falling. This device alerts staff when the client attempts to leave the bed, allowing for timely assistance and reducing the risk of falls. Placing the client in a room close to the nurses' station may help with supervision but does not provide immediate alerts like a bed exit alarm. Encouraging family members to stay with the client at all times may not be feasible, and raising all four side rails can lead to restraint issues and is not recommended unless necessary for the client's safety.

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.

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.
