Question 1 of 5
A patient came to the ER complaining of pain in her elbow after a fall. The x-ray shows fractured ulna at the olecranon process. There is also a suspected fracture of the radius. Which diagnostic test would be most helpful in determining a complete diagnosis?
Correct Answer: A
Rationale: A CT scan provides detailed imaging of bones, making it ideal for confirming suspected fractures like the radius fracture. MRI is better for soft tissue, bone scans for bone activity, and electromyelograms assess nerve function.
Question 2 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 3 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 4 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 5 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.
