In the Neuro ICU, a comatose patient has this posture in bed: Upper arms are flexed tight to the sides with elbows, wrists, and fingers flexed. The legs are extended and internally rotated. The nurse interprets this posture as:

Decorticate Rigidity

Flaccid

Decerebrate Rigidity

Hemiplegia

Answer and Explanation

The Correct Answer is A

A.   Decorticate rigidity is characterized by flexion of the arms and extension of the legs. In this posture, the upper arms are flexed and held tightly to the sides, with the elbows, wrists, and fingers also flexed. The legs are extended and internally rotated.
B.   Flaccid posture, or flaccidity, is characterized by a complete lack of muscle tone, which leads to a limp and lifeless appearance. There is no resistance to passive movement, and the muscles are weak or paralyzed.

C.   Decerebrate rigidity is characterized by extension of both the arms and the legs. In this posture, the arms are extended at the sides with the wrists and fingers flexed, and the legs are extended and internally rotated. This type of rigidity indicates damage to the brainstem below the red nucleus.
D.   Hemiplegia refers to paralysis of one side of the body, which can result from brain injury or stroke affecting one hemisphere of the brain. The affected side will have limited or no movement and muscle tone.

Correct Answer is C

Explanation

A. The trigeminal nerve (CN V) is primarily responsible for sensory information from the face and motor control of the muscles of mastication (chewing). It does not carry taste sensations. Instead, it is involved in sensation (e.g., touch, pain, temperature) of the face and mouth, but not taste.
B. The vagus nerve (CN X) has various functions, including parasympathetic control of the heart, lungs, and digestive tract, and sensory and motor functions in the throat and voice box. It does contribute to taste sensation in the region of the pharynx and the epiglottis, but it is not primarily responsible for the taste sensation on the posterior third of the tongue.
C. The glossopharyngeal nerve (CN IX) is responsible for taste sensation on the posterior one-third of the tongue. It also contributes to the sensory innervation of the pharynx and helps in the regulation of saliva production. This nerve is specifically involved in the taste perception in the back third of the tongue.
D. The facial nerve (CN VII) provides taste sensation to the anterior two-thirds of the tongue. It also controls the muscles of facial expression and contributes to the production of saliva and tears. The facial nerve does not provide taste sensation to the posterior third of the tongue.

A. Blurred vision B. Difficulty speaking C. Loss of tactile sensation D. inability to hear high-pitched sounds

Correct Answer is B

Explanation

A. Blurred vision is generally associated with visual system issues, which involve the occipital lobe or the visual pathways rather than the frontal lobe. Broca’s area, located in the frontal lobe, is involved in speech production and not in vision processing.
B. Difficulty speaking is a key symptom associated with damage to Broca’s area, which is located in the frontal lobe and responsible for speech production. A contusion in this area can lead to expressive aphasia, where the individual has trouble forming grammatically correct sentences and articulating words, while comprehension remains relatively intact.
C. Loss of tactile sensation would generally be associated with damage to the parietal lobe, where the primary somatosensory cortex is located. The parietal lobe processes sensory information such as touch, temperature, and pain. Since Broca’s area is located in the frontal lobe and primarily deals with language production, loss of tactile sensation is not typically expected from a frontal lobe contusion affecting Broca's area.
D. Inability to hear high-pitched sounds relates to issues with the auditory pathways or structures involved in hearing, such as the temporal lobe or the auditory cortex, not the frontal lobe. The frontal lobe and Broca’s area do not directly control auditory perception.
