A patient presents to the emergency department with signs of an epidural hematoma. Which manifestation is characteristic of this type of hematoma?

Loss of consciousness greater than 30 minutes following injury.

Lucid intervals followed by momentary unconsciousness.

Memory loss of the prior day's activities.

Amnesia of the injury event.

Answer and Explanation

The Correct Answer is B

Choice A reason:

Loss of consciousness greater than 30 minutes following injury can occur in various types of head injuries but is not specific to epidural hematomas.

Choice B reason:

Lucid intervals followed by momentary unconsciousness are characteristic of epidural hematomas. Patients with epidural hematomas often experience a period of lucidity following the initial loss of consciousness, followed by a rapid decline in mental status as the hematoma enlarges and increases intracranial pressure.

Choice C reason:

Memory loss of the prior day's activities can occur with various head injuries but is not specific to epidural hematomas.

Choice D reason:

Amnesia of the injury event is common in head injuries but is not specific to epidural hematomas. The hallmark of epidural hematomas is the pattern of lucid intervals followed by rapid deterioration.

Correct Answer is B

Explanation

Choice A reason:

Young adults ages 12-20 are at risk for spinal cord injuries due to sports and recreational activities. However, the highest risk group for spinal cord injuries, particularly from activities such as motor vehicle accidents and risky behaviors, is young men ages 16-30.

Choice B reason:

Young men ages 16-30 are the highest risk group for spinal cord injuries. This population is more likely to engage in high-risk activities such as driving, contact sports, and recreational activities that can lead to spinal cord injuries. Therefore, they would benefit most from targeted prevention education.

Choice C reason:

Children ages 2-15 are at risk for spinal cord injuries, particularly from falls and accidents. However, their risk is lower compared to the young adult male population. Education for this group is important but not as critical as for young men.

Choice D reason:

Elderly people ages 60 and up are at risk for spinal cord injuries, primarily from falls. While prevention education is important for this group, they are not the highest risk population compared to young men ages 16-30.

Correct Answer is ["83"]

Explanation

To calculate the infusion rate, divide the total volume of fluid to be infused by the total time over which the infusion should occur.

$\frac{330 \text{ mL}}{4 \text{ hours}} = 82.5 \text{ mL/hr}$

Rounding to the nearest whole number, the nurse should set the pump to deliver 83 mL/hr.
