A patient that is Comatose based on the Level of Consciousness (LOC) assessment using the Glasgow Coma scale is in what numeric range of the scale?

3-6

13-15

9-12

Answer and Explanation

The Correct Answer is A

A.   3- This is the lowest possible score on the GCS and reflects no eye opening, no verbal response, and no motor response to stimuli. Score of 4-6: The patient might exhibit some responses, but these responses are still severely impaired. For example, the patient might open their eyes to pain but not respond verbally or move purposefully.
B.   A GCS score in the range of 13 to 15 reflects a higher level of consciousness.
C.   A GCS score of 0 is not a valid score on the scale.
D.   A GCS score in the range of 9 to 12 reflects moderate impairment of consciousness.

Correct Answer is D

Explanation

A. Coma is a state of profound unconsciousness where the patient cannot be awakened and does not respond to any external stimuli. The patient is completely unresponsive, with no eye opening or verbal responses.
B. Stupor is a state where the patient is almost completely unresponsive and can only be awakened by vigorous or painful stimuli. When aroused, they may only give brief, non-purposeful responses.
C. Lethargy is characterized by drowsiness and decreased alertness. The patient may fall asleep easily but can be awakened and will respond appropriately to stimuli. They might appear sluggish or tired.
D. Obtunded refers to a state where the patient has a reduced level of consciousness and responsiveness. They may be difficult to arouse, respond slowly to stimuli, and have a dulled sense of awareness. They need increased stimulation to achieve a response.

A. CN V B. CN XII C. CN VII D. CN I

Correct Answer is B

Explanation

A. The trigeminal nerve (CN V) primarily controls sensation in the face and the muscles of mastication (chewing). While it is crucial for sensory input and motor control related to chewing, it does not directly control the movement of the tongue.
B. The hypoglossal nerve (CN XII) is responsible for controlling the movements of the tongue. A lesion of CN XII can cause the tongue to deviate towards the side of the weakness or damage. This is because the hypoglossal nerve innervates the muscles of the tongue, and damage to it results in weakness of the muscles on the affected side, causing the tongue to deviate towards that side when protruded.
C. The facial nerve (CN VII) controls the muscles of facial expression. While it affects facial movements and expressions, it does not control the movements of the tongue. A lesion in CN VII would typically result in facial asymmetry or weakness rather than tongue deviation.
D. The olfactory nerve (CN I) is responsible for the sense of smell. It does not have any role in controlling tongue movement. Therefore, a lesion in CN I would not cause deviation of the tongue.
