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.

Answer and Explanation

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 cerebral perfusion pressure (CPP) of 40 mm Hg is considered low, as the normal range for CPP is typically between 60 and 80 mm Hg. Low CPP can lead to inadequate blood flow to the brain.

Choice B rationale

An accurate CPP reading is crucial for assessing intracranial pressure and cerebral blood flow. A reading of 40 mm Hg is not typically considered inaccurate.

Choice C rationale

A CPP of 40 mm Hg is not within normal limits, as it is significantly below the normal range.

Choice D rationale

A CPP of 40 mm Hg is not high; it is considered low and requires medical attention.

A. Pustule. B. Macule. C. Vesicle. D. Cyst. E. Cyst.

Correct Answer is C

Explanation

Choice A rationale

A pustule is an elevated, round lesion filled with pus, not serum. Pustules are commonly seen in acne or infections.

Choice B rationale

A macule is a flat, discolored area of the skin that is not elevated. Macules do not contain fluid and are often seen in conditions like freckles or flat moles.

Choice C rationale

A vesicle is an elevated, round lesion filled with clear serum. Vesicles can result from conditions such as chickenpox, herpes simplex, or dermatitis.

Choice D rationale

A cyst is an elevated, round lesion filled with semi-solid material or fluid. Cysts are typically deeper in the skin compared to vesicles.
