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 D
Explanation
Choice A rationale
Fever is typically regulated by the hypothalamus, a part of the brain that controls body temperature. Dysfunction of the lower brain stem does not typically cause fever.
Choice B rationale
Visual disturbances are often related to issues with the visual cortex or optic pathways, which are not part of the lower brain stem.
Choice C rationale
Gait alteration is typically associated with dysfunction in the cerebellum or motor pathways, rather than the lower brain stem.
Choice D rationale
Hypoxia, or decreased oxygen levels, can be a critical concern with lower brain stem dysfunction as the lower brain stem controls vital autonomic functions such as respiration and heart rate.
Correct Answer is A
Explanation
Choice A rationale
The parietal lobe is responsible for processing sensory information and spatial awareness, including proprioception (the sense of body position in space). Damage to the parietal lobe can affect these functions.
Choice B rationale
The temporal lobe is involved in processing auditory information and memory, not spatial awareness. Damage to this lobe would affect hearing and memory rather than proprioception.
Choice C rationale
The frontal lobe is associated with executive functions, such as decision-making, problem-solving, and motor control, but not primarily with spatial awareness. Damage to this lobe impacts cognitive and motor functions.
Choice D rationale
The occipital lobe is primarily responsible for processing visual information. Damage to this lobe affects vision rather than spatial awareness or proprioception.
