A client has been experiencing an unexplained decline in knee function and has consequently been scheduled for arthrography.
The nurse should teach the client about what process?

Aspiration of synovial fluid for serologic testing.

Injection of corticosteroids into the client's knee joint to facilitate ROM.

Injection of a contrast agent into the knee joint prior to ROM exercises.

Replacement of the client's synovial fluid with a synthetic substitute.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Aspiration of synovial fluid for serologic testing is a procedure known as arthrocentesis, which involves extracting joint fluid for analysis. While useful for diagnosing conditions like infections or arthritis, it is not the same as arthrography, which involves imaging.

Choice B rationale

Injection of corticosteroids into the client's knee joint to facilitate ROM is a therapeutic procedure to reduce inflammation and improve movement in conditions like arthritis, but it is not part of an arthrography procedure.

Choice C rationale

Injection of a contrast agent into the knee joint prior to ROM exercises is a key part of arthrography. The contrast agent helps to enhance the imaging of the joint structures during movement, allowing for a detailed assessment of the joint.

Choice D rationale

Replacement of the client's synovial fluid with a synthetic substitute is not related to arthrography. This description aligns more with viscosupplementation, a treatment for osteoarthritis.

Correct Answer is C

Explanation

Choice A rationale

Deficient fluid volume is not the primary concern related to weight loss or ill-fitting dentures. While fluid intake should be monitored, it is less immediate than gastrointestinal issues from fiber deficiency.

Choice B rationale

Excessive intake of convenience foods might relate to weight loss but does not directly indicate a health risk. The primary risk is more focused on gastrointestinal function.

Choice C rationale

Constipation is a major risk due to limited fiber intake. Fiber is essential for bowel movement regularity, and its deficiency, coupled with ill-fitting dentures, increases the risk.

Choice D rationale

Infection is not directly related to the dietary concerns noted. While poor nutrition can weaken the immune system, it is not the most immediate health risk connected to the given symptoms. .

A. Low. B. Inaccurate. C. Within normal limits. D. High.

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. .
