A nurse discovers scabies when assessing a client who has just been transferred to the medical-surgical unit from the day surgery unit.
To prevent scabies infection in other clients, the nurse should:

Choice A rationale

Dysfunction in the cerebrum would likely result in different types of posturing, such as decorticate posturing, rather than decerebrate. The cerebrum is involved in controlling voluntary motor functions and damage here typically does not lead to decerebrate posturing.

Choice B rationale

Dysfunction in the brain stem results in decerebrate posturing, characterized by rigid extension of the arms and legs, downward pointing of the toes, and backward arching of the head. The brain stem is crucial for controlling basic life functions and its impairment leads to severe motor response issues.

Choice C rationale

Dysfunction in the spinal column typically does not lead to decerebrate posturing but may lead to different types of paralysis or movement issues depending on the location and severity of the damage.

Choice D rationale

Dysfunction in the motor cortex usually leads to abnormalities in voluntary movement, muscle tone, and coordination rather than decerebrate posturing which is more linked to brain stem issues.

Choice A rationale

Mixed muscular dystrophy leads to progressive deterioration in all voluntary muscles, causing increasing disability over time.

Choice B rationale

This statement is incorrect because mixed muscular dystrophy affects more than just the arms and pelvic muscles and leads to significant disability.

Choice C rationale

This is not an appropriate response as it does not provide any information and deflects the client's question.

Choice D rationale

Mixed muscular dystrophy is not considered benign, as it causes significant and progressive muscle deterioration.
