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.
Replacement of the client's synovial fluid with a synthetic substitute.
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 ["A","B","C"]
Explanation
Choice A rationale
Scales represent the accumulation of dead skin cells that flake off, a common secondary lesion in eczema resulting from the chronic inflammation and rapid skin cell turnover.
Choice B rationale
Erosion occurs when the superficial layer of skin is lost, typically due to scratching or friction in eczema, exposing the underlying epidermis and sometimes leading to infection.
Choice C rationale
Crusts form when serum, blood, or purulent exudate dries on the skin surface, often seen in eczema as a result of weeping lesions and subsequent drying.
Choice D rationale
Ulcers are deeper lesions extending into the dermis or subcutaneous tissue and are not typically associated with eczema. Eczema usually affects the epidermis, causing secondary lesions like scales, erosion, and crusts rather than deep tissue ulcers.
Correct Answer is A
Explanation
Choice A rationale
The nurse should check the equipment first when an ICP reading of 0 mm Hg is noted, as this may indicate equipment malfunction. An accurate ICP reading is critical for assessing and managing intracranial pressure to ensure the client's safety.
Choice B rationale
Continuing the assessment without checking the equipment may lead to incorrect conclusions based on a potentially faulty reading. It’s crucial to ensure the accuracy of the equipment before proceeding.
Choice C rationale
Documenting the reading as an effective treatment outcome without verifying its accuracy can be dangerous. An ICP reading of 0 mm Hg is unusual and warrants equipment verification.
Choice D rationale
Contacting the health care provider to review the care plan is premature until the equipment has been checked to rule out a false reading, ensuring the nurse provides accurate information.
