A 54 year-old client diagnosed with Bipolar disorder is clenching his jaw closed to avoid taking a prescribed oral medication. The nurse can use this observation to confirm the client is demonstrating motor function of which cranial nerve?
Vagus
Facial
Glossopharygeal
Trigeminal
The Correct Answer is D
A. Vagus: The vagus nerve (cranial nerve X) is involved in regulating autonomic functions, such as heart rate and digestion. It does not play a significant role in controlling jaw movements or clenching.
B. Facial: The facial nerve (cranial nerve VII) controls facial expressions, such as smiling or frowning, and also contributes to taste sensation in the anterior two-thirds of the tongue. While it is related to facial motor function, it does not control the jaw muscles responsible for clenching.
C. Glossopharyngeal: The glossopharyngeal nerve (cranial nerve IX) is involved in taste sensation on the posterior one-third of the tongue, as well as in swallowing and salivation. It does not control the jaw muscles used for clenching.
D. Trigeminal: The trigeminal nerve (cranial nerve V) is responsible for sensation in the face and motor functions related to chewing. It innervates the muscles of mastication, including those involved in clenching the jaw. The client’s jaw clenching is a direct manifestation of motor function associated with the trigeminal nerve.

Correct Answer is C
Explanation
A) Tricuspid and mitral: The tricuspid and mitral valves are best auscultated over the areas where the heart's valves are closest to the chest wall, specifically at the lower left sternal border and the apex, respectively. A louder S2 in the 2nd intercostal space right sternal border does not indicate the closure of these valves.
B) Mitral and aortic: The mitral valve is auscultated at the apex, and the aortic valve is best heard at the 2nd intercostal space right sternal border. While a louder S2 may be associated with the aortic valve, it is not consistent with the mitral valve.
C) Aortic and pulmonic: The aortic valve and pulmonic valve are located in the areas where S2 (second heart sound) is predominantly heard. The aortic valve is located at the 2nd intercostal space right sternal border, and the pulmonic valve is heard at the 2nd intercostal space left sternal border. A louder S2 in the 2nd intercostal space right sternal border indicates a louder closure of the aortic valve and potentially the pulmonic valve as well.
D) Pulmonic and tricuspid: The pulmonic valve is auscultated at the 2nd intercostal space left sternal border, while the tricuspid valve is heard best at the lower left sternal border. A louder S2 in the 2nd intercostal space right sternal border does not indicate the closure of the tricuspid valve.
Correct Answer is C
Explanation
A. Glenohumeral joint: The glenohumeral joint is the shoulder joint. Pain with chewing is unlikely to be related to issues with the shoulder joint, as this joint is not involved in the chewing process.
B. Sternoclavicular joint: The sternoclavicular joint is where the clavicle meets the sternum. Problems here might affect shoulder and chest movement, but they would not typically cause pain specifically related to chewing.
C. Temporomandibular joint (TMJ): The TMJ is directly involved in the movement of the jaw, which is essential for chewing. Chronic pain during chewing often indicates a problem with the TMJ, such as TMJ disorder, which can cause pain, clicking, and other issues when moving the jaw.
D. Acromioclavicular joint: The acromioclavicular joint is located at the top of the shoulder where the clavicle meets the acromion of the scapula. This joint primarily affects shoulder movement, not chewing.
