A patient admitted to the medical-surgical unit was recently weaned from a mechanical ventilator and an IV infusion of lorazepam.
The patient has been alert and oriented for 24 hours but is now experiencing confusion.
The practical nurse assists the registered nurse with the evaluation of new-onset confusion by assessing the patient’s sense of place and time, difficulty focusing, short-term memory loss, and increased lethargy.
What condition does the practical nurse suspect in this patient?
Psychosis.
Dementia.
Amnesia.
Delirium.
The Correct Answer is D
Choice D rationale
Delirium is a sudden onset of confusion that can be caused by a variety of factors, including withdrawal from certain medications like lorazepam. Symptoms can include disorientation, difficulty focusing, short-term memory loss, and increased lethargy.
Choice A rationale
Psychosis is a severe mental disorder characterized by a disconnection from reality. It often involves hallucinations or delusions, which are not mentioned in the scenario.
Choice B rationale
Dementia is a chronic or persistent disorder of the mental processes caused by brain disease or injury. It is marked by memory disorders, personality changes, and impaired reasoning. It typically does not have a sudden onset.
Choice C rationale
Amnesia is a condition in which one’s memory is lost or disturbed. It can be caused by brain injury or severe emotional trauma. The scenario does not provide information suggesting the patient has experienced a loss of memory.
