The nurse is caring for an older adult client who has recently had a stroke. The nurse assesses that the right side of the client's face is drooping. The nurse might also expect which of the following assessment findings?

A. Nystagmus in extreme superior gaze: Nystagmus is an involuntary eye movement and is not a normal finding, especially in extreme superior gaze. Nystagmus can be indicative of neurological issues and requires further evaluation.

B. Slight amount of lid lag when moving the eyes from a superior to an inferior position: Lid lag refers to a delay in the downward movement of the upper eyelid during eye movement. This can be a sign of hyperthyroidism and is not a normal finding.

C. Parallel movement of both eyes: This is the correct answer. During the diagnostic positions test, the nurse should observe parallel movement of both eyes in all directions, indicating normal extraocular muscle function and coordination.

D. Convergence of the eyes: Convergence refers to the inward movement of both eyes when focusing on a close object. While convergence is a normal phenomenon, it is not specifically assessed during the diagnostic positions test, which primarily evaluates the range of motion and coordination of the extraocular muscles.

A. The third heart sound (S3):

The third heart sound (S3) is an abnormal heart sound that occurs during early diastole, immediately after S2 (the second heart sound). It is caused by the rapid filling of the ventricles and is often associated with conditions like heart failure. In heart failure, the ventricles become stiff, causing vibrations that produce the S3 sound.

B. A friction rub:

A friction rub is a high-pitched, scratchy sound heard during both systole and diastole. It is caused by the rubbing together of inflamed pericardial layers (pericarditis) and is usually heard best at the left lower sternal border. Friction rubs can indicate pericardial inflammation and are often heard in conditions such as pericarditis or after a myocardial infarction.

C. The fourth heart sound (S4):

The fourth heart sound (S4) occurs late in diastole, just before S1, and is caused by atrial contraction. It is associated with increased resistance to ventricular filling, often due to conditions like hypertension or aortic stenosis. The S4 sound is heard as a low-pitched "atrial gallop."

D. A split second heart sound S2:

The second heart sound (S2) represents the closure of the aortic and pulmonic valves. Normally, S2 has two components: A2 (aortic valve closure) and P2 (pulmonic valve closure). A split S2 occurs when A2 and P2 do not close simultaneously. A physiological split S2 is common during inspiration and occurs due to delayed closure of the pulmonic valve. An abnormal or fixed split S2 can indicate underlying heart conditions such as atrial septal defect (ASD) or right bundle branch block (RBBB).
