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 B
Explanation
Choice A rationale
Cushing triad is a late sign of increased ICP, characterized by bradycardia, hypertension, and irregular respirations, appearing after other symptoms like decreased LOC.
Choice B rationale
Decreased LOC is one of the earliest signs of increased ICP as it reflects the brain's response to pressure changes, alerting the need for immediate intervention.
Choice C rationale
Headache can be an early sign but is not as sensitive or specific as changes in LOC when assessing for increased ICP.
Choice D rationale
Coma is a late sign of significantly increased ICP, indicating severe brain dysfunction, often following initial symptoms like decreased LOC.
Correct Answer is D
Explanation
Choice A rationale
Water or saline baths can help soothe skin but are not typically prescribed for psoriasis as a therapeutic measure.
Choice B rationale
Sodium bicarbonate baths are often used for itching and skin irritation but are not specifically recommended for psoriasis.
Choice C rationale
Colloids like oatmeal can be soothing for skin conditions, but they do not have the therapeutic properties needed for treating psoriasis flares.
Choice D rationale
Medicated tars are commonly used in the treatment of psoriasis because they can help reduce scaling, itching, and inflammation. They work by slowing the rapid growth of skin cells and are often prescribed for severe cases.
