ATI PN Comprehensive Predictor 2024

Correct Answer: A

Rationale: The correct answer is A: Decerebrate posturing. Decerebrate posturing is an abnormal body posture characterized by rigid extension of the arms and legs, which indicates severe brainstem injury affecting the midbrain and pons. This posture suggests dysfunction or damage to neural pathways controlling muscle tone. Choice B, hypervigilance, is not typically associated with brainstem injury but rather with increased alertness and arousal. Choice C, absence of deep tendon reflexes, is not a specific finding related to brainstem injury. Choice D, a Glasgow Coma Scale score of 15, indicates a fully awake and alert state, which is not expected in a client with a brainstem injury.

Correct Answer: B

Rationale: Tingling in the fingers is a classic sign of hypocalcemia. Following a thyroidectomy, hypocalcemia can occur due to damage to the parathyroid glands, which regulate calcium levels in the body. Nausea, numbness in the toes, and sweating are not specific signs of hypocalcemia. Numbness and tingling usually start in the hands and feet due to their increased nerve sensitivity to low calcium levels.

Correct Answer: B

Rationale: The correct intervention for a client with dementia at risk of falls is to use a bed exit alarm to notify staff when the client tries to leave the bed. This intervention helps prevent falls while still allowing some freedom of movement. Choice A is incorrect because using restraints can lead to complications and is considered a form of restraint which should be avoided. Choice C is not suitable for a client at high risk of falls due to dementia as it may increase the risk of falls. Choice D is not recommended as raising all four side rails can be considered a form of physical restraint and may not be the best approach to prevent falls in a client with dementia.

Correct Answer: D

Rationale: The correct answer is D: 'I should report any chest pain during the test.' This statement indicates an understanding of the teaching because reporting chest pain during an exercise stress test is crucial as it may signify cardiac distress. Choices A, B, and C are incorrect. Eating a large meal 2 hours before the test is not recommended as it may affect the results. Avoiding drinking water before the test is also not advisable as staying hydrated is important. Stopping blood pressure medication without medical advice can be dangerous, especially before a stress test.
