CRRN Rehabilitation Registered Nurse Certification 4

Question 1

A patient with a C4 complete spinal cord injury is most likely to require which form of respiratory support?

Accepted Answer

Mechanical ventilation, at least initially

Answer

C4 injuries affect the phrenic nerve (C3–C5) that drives diaphragm function, often necessitating mechanical ventilation because spontaneous breathing is severely impaired or absent.

Question 2

A patient with neurogenic bladder after SCI is being taught intermittent catheterization (CIC). The nurse should instruct the patient to catheterize every:

Accepted Answer

4–6 hours with a goal of volumes under 400–500 mL

Answer

CIC every 4–6 hours maintains bladder volumes below 400–500 mL, which prevents overdistension, reduces infection risk, and protects upper urinary tract function.

Question 3

When caring for a patient in the subacute phase of a stroke, the CRRN observes shoulder subluxation on the hemiplegic side. The priority nursing action is:

Accepted Answer

Position the arm with proper support and educate the patient and family on handling techniques

Answer

Proper positioning, arm support troughs, and education on safe handling prevent further subluxation and shoulder-hand syndrome without restricting therapeutic use of the limb.

Question 4

A CRRN is teaching a patient with a T6 SCI about bowel management. Which statement about a neurogenic bowel program is correct?

Accepted Answer

A consistent scheduled time after a meal is recommended to utilize the gastrocolic reflex.

Answer

Scheduling bowel care 20–30 minutes after a meal exploits the gastrocolic reflex, which increases colonic peristalsis and facilitates more predictable and complete evacuation.

Question 5

Which outcome measure is specifically designed to assess ambulation ability and community mobility in patients with lower-limb impairment?

Accepted Answer

10-Meter Walk Test (10MWT)

Answer

The 10-Meter Walk Test measures walking speed over a short distance and is a reliable, sensitive indicator of gait speed changes and functional ambulation in rehabilitation populations.
