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 C
Explanation
Choice A rationale
Cranial nerve VII (Facial nerve) controls muscles of facial expression and functions in taste sensations from the anterior two-thirds of the tongue, not balance.
Choice B rationale
Cranial nerve VI (Abducens nerve) controls lateral eye movement and has no role in balance or proprioception.
Choice C rationale
Cranial nerve VIII (Vestibulocochlear nerve) is responsible for hearing and balance. A positive Romberg test indicates issues with proprioception or vestibular function, which is directly linked to this nerve.
Choice D rationale
Cranial nerve IX (Glossopharyngeal nerve) involves taste sensation from the posterior third of the tongue and some swallowing functions, not balance.
Correct Answer is C
Explanation
Choice A rationale
Encouraging adequate water intake by the client is a general recommendation for maintaining hydration but does not address the client's fear of the EEG procedure, nor does it dispel misconceptions about electrical shock.
Choice B rationale
Distracting the client's attention from the test may provide temporary relief from anxiety but does not address or correct the client's specific fear related to being electrocuted during the EEG procedure.
Choice C rationale
Informing the client that they will not experience any electrical shock is crucial in dispelling the client's fear. An EEG measures electrical activity in the brain using sensors on the scalp; it does not involve delivering electrical shocks to the client.
Choice D rationale
Informing the client that they will experience only mild electrical shock is incorrect and could increase the client's fear. An EEG does not administer any form of electrical shock to the client; it is a non-invasive and painless procedure.
