A clinic nurse is caring for a client with a history of osteoporosis. What diagnostic test will best allow the care team to assess the client's risk of fracture?
Bone densitometry.
Arthrography.
Bone scan.
Arthroscopy.
Vagus nerve.
The Correct Answer is A
Choice A rationale
Bone densitometry is a non-invasive test that measures bone mineral density (BMD). It helps to identify the presence of osteoporosis and assess fracture risk by comparing the patient's bone density to that of a healthy young adult. Low BMD indicates higher fracture risk. This test is essential for monitoring osteoporosis progression and guiding treatment decisions.
Choice B rationale
Arthrography involves injecting contrast dye into a joint before imaging with X-ray or MRI. It evaluates joint structures, such as cartilage, ligaments, and capsules, but it is not specifically designed to measure bone density or assess fracture risk.
Choice C rationale
A bone scan involves injecting a small amount of radioactive material into the bloodstream, which accumulates in areas of high bone activity. It detects bone abnormalities, such as fractures, infections, or tumors. However, it is not used for assessing bone density or fracture risk.
Choice D rationale
Arthroscopy is a minimally invasive surgical procedure that allows direct visualization of joint structures using a small camera. It is primarily used for diagnosing and treating joint problems, such as torn ligaments or cartilage, but it does not assess bone density or fracture risk.

Correct Answer is A
Explanation
Choice A rationale
A CPP of 40 mm Hg is considered low and indicates inadequate cerebral perfusion pressure, which requires immediate medical intervention.
Choice B rationale
A low CPP indicates compromised cerebral blood flow, leading to potential brain ischemia and damage.
Choice C rationale
A reading of 40 mm Hg is not inaccurate if it reflects the actual CPP of the client.
Choice D rationale
A CPP of 40 mm Hg is not high; it is low and requires prompt attention. .
Correct Answer is C
Explanation
Choice A rationale
Selective estrogen receptor modulators (SERMs) are used for osteoporosis but are not typically the first-line treatment. They help to maintain bone density by mimicking estrogen's beneficial effects on bone.
Choice B rationale
Calcitonin is used to treat osteoporosis but is not considered a first-line medication. It works by inhibiting bone resorption, which helps to slow bone loss.
Choice C rationale
Bisphosphonates are the first-line medication for treating and preventing osteoporosis. They work by inhibiting bone resorption, which helps to maintain or increase bone density and reduce the risk of fractures.
Choice D rationale
Anabolic agents, such as parathyroid hormone analogs, are used for osteoporosis but are typically reserved for severe cases or when other treatments are not effective. They work by stimulating bone formation.
