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","B","C"]
Explanation
Choice A rationale
Bradycardia (slow heart rate) is one of the key components of Cushing's triad, which indicates increased intracranial pressure and impending herniation.
Choice B rationale
Bradypnea (slow respiratory rate) is another manifestation of Cushing's triad and reflects brainstem compression.
Choice C rationale
Hypertension (high blood pressure) is the third component of Cushing's triad, resulting from the body's attempt to maintain cerebral perfusion.
Choice D rationale
Tachycardia (rapid heart rate) is not a sign of Cushing's triad and is not associated with increased intracranial pressure.
Correct Answer is D
Explanation
Choice A rationale
Stupor refers to a state of near-unconsciousness or insensibility, where the patient can be briefly aroused by vigorous or repeated stimuli.
Choice B rationale
Somnolence refers to a state of strong desire for sleep or sleeping for unusually long periods (drowsiness), but it is not as severe as stupor or coma.
Choice C rationale
Normal consciousness means the patient is awake, alert, and responsive to their environment with no neurological deficits.
Choice D rationale
A score of 6 on the Glasgow Coma Scale indicates deep coma, where the patient has minimal to no response to stimuli, indicating severe brain injury.
