Which posture is exhibited by abnormal flexion of the upper extremities and extension of the lower extremities?
Normal.
Decorticate.
Decerebrate.
Flaccid.
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
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.
