Question 1

A patient 3 days post-total hip arthroplasty (posterior approach) asks to cross their legs while sitting. What is the correct nursing response?

Accepted Answer

Instruct the patient to avoid crossing the legs to prevent hip dislocation

Answer

After a posterior-approach total hip arthroplasty, crossing the legs is prohibited as it causes hip adduction and internal rotation, placing the patient at risk for dislocation.

Question 2

When using the numeric rating scale (NRS) for pain assessment, a patient with aphasia rates their pain as 0 but grimaces and guards during movement. What should the nurse do?

Accepted Answer

Use a behavioral pain observation tool to supplement assessment

Answer

For patients who cannot reliably self-report pain, behavioral observation tools (e.g., CPOT, PAINAD) should supplement or replace self-report scales.

Question 3

A patient with chronic low back pain is started on gabapentin. What is the primary therapeutic mechanism relevant to rehabilitation nursing?

Accepted Answer

It modulates calcium channel activity to reduce neuropathic pain transmission

Answer

Gabapentin binds to the alpha-2-delta subunit of voltage-gated calcium channels in the dorsal horn, reducing neuropathic pain signal transmission.

Question 4

A rehabilitation nurse notes that a patient with incomplete SCI ambulates with a steppage gait pattern. Which nerve root level deficit BEST explains this finding?

Accepted Answer

L4-L5 (dorsiflexors)

Answer

Steppage gait results from foot drop due to weakness of ankle dorsiflexors innervated primarily at L4-L5, causing the patient to exaggerate hip and knee flexion to clear the foot.

Question 5

Which transfer technique is MOST appropriate for a patient with complete right hemiplegia who has good left-sided strength and is cooperative?

Accepted Answer

Pivot transfer toward the stronger (left) side

Answer

Pivot transfers should be performed toward the patient's stronger side to maximize their ability to assist and improve safety and success.
