Which posture is exhibited by abnormal flexion of the upper extremities and extension of the lower extremities?

Normal.

Decorticate.

Decerebrate.

Flaccid.

Answer and Explanation

The Correct Answer is B

Choice A rationale

Normal posture involves relaxed and symmetrical positioning of the limbs without any abnormal flexion or extension.

Choice B rationale

Decorticate posturing is characterized by abnormal flexion of the upper extremities at the elbows and wrists, and extension of the lower extremities, often indicating damage to the corticospinal tract.

Choice C rationale

Decerebrate posturing involves extension and outward rotation of both the arms and legs, indicating damage to the brain stem, which is more severe than decorticate posturing.

Choice D rationale

Flaccid posture refers to a complete lack of muscle tone and resistance, often seen in severe cases of neurological damage or after a stroke. .

Correct Answer is D

Explanation

Choice A rationale

Stupor refers to a state of near-unconsciousness or insensibility, where the patient can be briefly aroused by vigorous or repeated stimuli.

Choice B rationale

Somnolence refers to a state of strong desire for sleep or sleeping for unusually long periods (drowsiness), but it is not as severe as stupor or coma.

Choice C rationale

Normal consciousness means the patient is awake, alert, and responsive to their environment with no neurological deficits.

Choice D rationale

A score of 6 on the Glasgow Coma Scale indicates deep coma, where the patient has minimal to no response to stimuli, indicating severe brain injury.

A. It is a test for motor ability. B. It is a test for balance. C. It is a test for coordination. D. It is a test for muscle strength.

Correct Answer is B

Explanation

Choice A rationale

The Romberg test does not assess motor ability. Motor ability tests typically involve assessing muscle strength, coordination, and movement.

Choice B rationale

The Romberg test is used to assess balance. It evaluates the client's ability to maintain a steady position with eyes closed, indicating the integrity of the proprioceptive and vestibular systems.

Choice C rationale

The Romberg test does involve coordination, but its primary focus is on balance rather than coordination alone. Coordination tests usually involve tasks requiring fine motor control.

Choice D rationale

The Romberg test does not assess muscle strength. Muscle strength tests involve evaluating the force generated by muscles during contraction.
