What is one of the first assessments that a nurse should include when performing an initial nutritional screening on a new patient?

Choice A reason: Cranial Nerve VII (facial nerve) controls facial expression muscles. Asking the patient to smile tests the nerve’s motor function, specifically the zygomaticus muscles, which elevate the mouth corners, making this a correct assessment task for this nerve.

Choice B reason: Closing eyes tightly assesses Cranial Nerve VII’s motor function, specifically the orbicularis oculi muscle, which closes the eyelids. Weakness or asymmetry indicates potential facial nerve dysfunction, making this a correct task for evaluating this nerve.

Choice C reason: Shrugging shoulders tests Cranial Nerve XI (spinal accessory nerve), which innervates the trapezius and sternocleidomastoid muscles. This action is unrelated to Cranial Nerve VII’s facial motor functions, making it an incorrect choice for this assessment.

Choice D reason: Frowning assesses Cranial Nerve VII’s control over the corrugator supercilii and procerus muscles, which wrinkle the brow and depress the mouth. This task evaluates facial nerve function, making it a correct choice for the assessment.

Choice E reason: Smelling a flower tests Cranial Nerve I (olfactory nerve), responsible for smell sensation. This is unrelated to Cranial Nerve VII’s motor functions for facial expressions, making it an incorrect task for assessing this nerve.

Choice A reason: Opisthotonos is a severe arching of the back with hyperextension of the neck and limbs due to intense muscle spasms, often linked to tetanus or severe meningitis. It does not involve the specific arm adduction and foot plantar flexion with internal rotation described. This posture is unrelated to the neurological damage indicated, as it reflects a different pathological mechanism.

Choice B reason: Flaccid quadriplegia involves complete loss of muscle tone and voluntary movement in all four limbs, typically from spinal cord injury or neuromuscular disorders. The patient’s rigid arm adduction and plantar flexion indicate active muscle contraction, not flaccidity, making this an incorrect descriptor for the observed posture.

Choice C reason: Decorticate rigidity features arm flexion, clenched fists, and extended legs, typically due to cerebral cortex or internal capsule damage above the brainstem. The patient’s arm adduction and foot plantar flexion with internal rotation do not match this pattern, as decorticate posture lacks the internal rotation component.

Choice D reason: Decerebrate rigidity is marked by arm adduction, extension, and internal rotation, with legs extended and feet plantar flexed, as observed. This results from severe brainstem injury below the midbrain, disrupting corticospinal and vestibulospinal tracts, leading to unopposed extensor activity, accurately describing the patient’s posture.
