Question 1 of 5
A 10-year-old has a fractured left leg with no trauma occurring to cause it. The health-care provider diagnoses a pathological fracture, possibly from a bone tumor. What type of diagnostic test would be ordered in this situation?
Correct Answer: B
Rationale: An MRI is best for evaluating soft tissue and potential bone tumors causing a pathological fracture. CT scans focus on bone structure, bone scans detect bone activity, and electromyelograms assess nerve function.
Question 2 of 5
The components of the hip joint that form the ball and socket are the
Correct Answer: D
Rationale: The hip joint's ball and socket are formed by the femoral head (ball) and the acetabulum (socket). Other options include incorrect bone pairings.
Question 3 of 5
You are working in a home health setting. Which of the following assessments would cause you to consider asking your supervisor to arrange for a physical therapy referral for your patient?
Correct Answer: B
Rationale: Holding onto furniture to ambulate post-surgery indicates unsafe mobility, warranting a physical therapy referral to improve strength and safety. Other options suggest stable mobility or adequate support.
Question 4 of 5
You are working in a long-term care setting. One of the residents is able to ambulate but sits in a wheelchair each day. What action will you take?
Correct Answer: A
Rationale: Promoting mobility by following ambulation orders prevents complications like muscle atrophy. Changing orders or assuming non-ambulation is premature without assessment.
Question 5 of 5
Explain the purpose of an abduction pillow.
Correct Answer: A
Rationale: An abduction pillow maintains hip alignment post-surgery (e.g., hip replacement) to prevent dislocation. It does not primarily elevate legs, reduce pain, or support the back.
