The nurse is performing a neurologic assessment on a client diagnosed with a stroke and cannot elicit a gag reflex. This deficit is related to which of the following cranial nerves?
Trigeminal nerve.
Facial nerve.
Glossopharyngeal nerve.
Vagus nerve.
Correct Answer : C,D
Choice A rationale
The trigeminal nerve is responsible for facial sensation and motor functions like chewing, not related to gag reflex impairment.
Choice B rationale
The facial nerve controls facial expressions, taste sensations, and other functions but does not influence the gag reflex.
Choice C rationale
The glossopharyngeal nerve (cranial nerve IX) plays a crucial role in the gag reflex as it innervates part of the pharynx and is responsible for sensory functions in the throat.
Choice D rationale
The vagus nerve (cranial nerve X) also contributes to the gag reflex, providing motor innervation to the pharyngeal muscles and aiding in swallowing and speech functions.

Correct Answer is B
Explanation
Choice A rationale
Hematoma formation is the initial stage of fracture healing, where a blood clot forms around the fracture site, creating a foundation for subsequent healing phases.
Choice B rationale
Remodeling is the final phase of bone healing, where compact bone replaces spongy bone, restoring the bone's structure and function.
Choice C rationale
Bony callus formation involves the development of new bone (callus) around the fracture site, which eventually transitions to compact bone during remodeling.
Choice D rationale
Fibrocartilaginous callus formation is an earlier stage of fracture healing, characterized by the formation of a soft callus made of collagen and cartilage that stabilizes the fracture.
Correct Answer is D
Explanation
Choice A rationale
Necrosis is tissue death resulting from prolonged pressure, often a consequence rather than the direct cause of pressure ulcers. The primary cause is sustained pressure impairing blood flow.
Choice B rationale
Low capillary pressure does not directly cause pressure ulcers. They result from sustained external pressure exceeding capillary perfusion pressure, leading to ischemia and tissue damage.
Choice C rationale
Increased mobility actually prevents pressure ulcers by reducing sustained pressure on any one area, enhancing blood flow and tissue health. Immobility is a significant risk factor, not increased mobility.
Choice D rationale
Extrinsic factors like sustained pressure, friction, shear, and moisture contribute directly to pressure ulcer development by compromising skin integrity and blood flow, leading to tissue ischemia and damage.
