Which of the following tests would be most appropriate for the nurse to use when assessing motor function of the trigeminal nerve?

A. This test assesses the function of the oculomotor nerve (CN III), not the trigeminal nerve. The oculomotor nerve controls the constriction and dilation of the pupils, as well as some eye movements. Therefore, this choice is not appropriate for assessing the trigeminal nerve.
B. This test assesses the sensory function of the trigeminal nerve (CN V). The trigeminal nerve provides sensation to the face, and testing the ability to differentiate between sharp and dull sensations evaluates

the sensory component of this nerve. However, this test does not assess the motor function of the trigeminal nerve.
C. This test evaluates the motor function of the trigeminal nerve. The trigeminal nerve controls the muscles involved in chewing, including the temporal and masseter muscles. By palpating these muscles while the client clenches their teeth, the nurse assesses the strength and function of these muscles, which are innervated by the trigeminal nerve. This is a direct test of motor function for CN V.
D. This test assesses the function of the facial nerve (CN VII), which controls the muscles of facial expression. It is not relevant for assessing the trigeminal nerve, which is involved in both sensory functions of the face and motor functions related to chewing.

A. Lateral epicondylitis, commonly known as "tennis elbow," is an overuse injury characterized by pain and tenderness on the outer part of the elbow (lateral epicondyle). It results from repeated stress and

strain on the forearm muscles and tendons, often due to activities involving repetitive arm motions such as tennis. The pain typically worsens with activities involving gripping, extending, or lifting.
B. Rheumatoid arthritis (RA) is a chronic inflammatory disease that typically affects joints symmetrically, causing pain, swelling, and stiffness. It usually involves joints like the hands, wrists, and knees rather than the elbows alone. RA symptoms are generally more diffuse and persistent, rather than specifically linked to recent physical activity and localized pain associated with movement.
C. Gout is a form of arthritis caused by the accumulation of uric acid crystals in the joints. It often presents with sudden, severe pain, redness, and swelling, typically affecting the big toe but can also affect other joints. Gout attacks usually occur at night and are often very acute and localized. It is less likely to be associated with the type of pain described (pain during extension and flexion) and recent physical activity.
D. Medial epicondylitis, also known as "golfer’s elbow," is similar to lateral epicondylitis but affects the inner part of the elbow (medial epicondyle). It is more commonly associated with activities that involve gripping and wrist flexion rather than the generalized extension and flexion pain described.
