Correct Answer is D
Explanation
A. Within 1 to 2 months. While some recovery may be seen within the first 1 to 2 months, it is typically an ongoing process, and significant improvements are often seen over a longer period.
B. Within 2 to 3 weeks. This timeframe is too short for significant recovery of neurologic function. Initial recovery is most rapid in the first few weeks, but continued improvement is expected over months.
C. Within 6 to 9 months. While recovery can continue up to 6 to 9 months or longer, most significant improvements in neurologic function occur within the first 3 to 6 months.
D. Within 3 to 6 months. This is the period during which the most significant recovery of neurologic function typically occurs following a stroke.
Correct Answer is A
Explanation
A. Use nightlights and remove extra furniture from the room: Nightlights provide gentle lighting that can reduce disorientation, and removing extra furniture minimizes fall risk.
B. Place the patient in a room with another recovering patient. This might increase agitation and disrupt both patients' sleep.
C. Instruct the patient to orient himself to his surroundings at bedtime. This may not be effective due to the patient's disorientation during detoxification.
