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
Rigidity is characterized by a continuous resistance to passive movement in any direction and does not specifically occur during abrupt dorsiflexion of the foot.
Choice B rationale
Flaccidity refers to decreased muscle tone or limpness, which is the opposite of hyperactivity or spasticity, and would not be observed with abrupt dorsiflexion.
Choice C rationale
Ataxia involves uncoordinated or erratic movements and is related to cerebellar dysfunction. This is not specifically triggered by abrupt dorsiflexion of the foot.
Choice D rationale
Clonus is the correct term for rhythmic, involuntary contractions of a muscle that occur when it is suddenly stretched, such as with abrupt dorsiflexion of the foot. It is a sign of hyperactive reflexes and upper motor neuron lesions.
Correct Answer is D
Explanation
Choice A rationale
Interactive dressings are designed to interact with the wound environment to promote healing. These can include dressings that release medication or create an optimal moisture balance. They are not typically used for acutely inflamed and oozing skin lesions.
Choice B rationale
Passive dressings are protective covers that keep the wound clean and protected from external contaminants. They do not have additional properties to manage wound exudate or inflammation.
Choice C rationale
Protective dressings are generally used to shield wounds from further injury or contamination. They do not specifically address the needs of an oozing and inflamed lesion.
Choice D rationale
Occlusive dressings are designed to maintain a moist wound environment, which can aid in the healing of oozing wounds. They can also provide a barrier to external contaminants and help manage exudate effectively, making them suitable for acutely inflamed and oozing lesions.
