A nurse is teaching a client who is scheduled for dual-energy x-ray absorptiometry (DXA) to screen for osteoporosis. Which of the following instructions should the nurse include in the teaching?
"You will need to fast for 12 hours before the test."
"You will need to lie flat for 4 hours following the test."
"You will need to remove all jewelry before the test."
"You will need to empty your bladder before the test."
The Correct Answer is C
A. Fasting is not necessary for a dual-energy x-ray absorptiometry (DXA) scan, as it does not involve ingesting anything.
B. The client does not need to lie flat for an extended period following a DXA scan. They can resume normal activities immediately after the test.

Correct Answer is C
Explanation
A. Teaching the primary caregiver is an important component of post-discharge planning, but the focus of rehabilitative care is on the client’s functional recovery, mobility, and independence rather than solely caregiver instruction.
B. Rehabilitation supports recovery, but effective outcomes require early initiation. Planning and interventions often start during hospitalization to address mobility deficits, prevent complications such as pressure injuries or deconditioning, and prepare the client for a safe transition to the next level of care.
C. Rehabilitative care begins with hospital admission, when the healthcare team evaluates the client’s physical and functional status, develops individualized goals, and initiates early interventions. Early rehabilitation is supported by research to improve mobility, reduce length of stay, and optimize long-term functional outcomes.
D. Rehabilitation is not confined to long-term care facilities; it can occur in hospitals, outpatient clinics, specialized rehab centers, and at home, depending on the client’s needs and recovery trajectory.
Correct Answer is C
Explanation
A. Twisting at the waist while lifting or moving an object can strain the back muscles and potentially lead to injury. The nurse should advise against this.
B. Relaxing the abdominal muscles while lifting an object can lead to inadequate support for the spine, potentially causing further strain or injury. The nurse should instruct the client to engage the abdominal muscles for stability.
C. Correct. Bending at the knees when picking up an object helps distribute the weight more evenly and reduces strain on the back muscles. This is a safe and recommended technique for lifting.
D. Holding an object away from the body while lifting it can increase the strain on the back muscles. The client should be advised to keep the object close to their body for better support and balance.
