The nurse is preparing to measure the visual acuity of a client. The nurse should recognize that which of the following cranial nerve should be assessed:
VI
V
II
III
The Correct Answer is C
A. VI
Cranial Nerve VI is the Abducent Nerve, which controls the movement of the lateral rectus muscle, allowing the eye to move laterally (abduct). Dysfunction of this nerve can cause difficulty in moving the eye outward.
B. V
Cranial Nerve V is the Trigeminal Nerve. It has both sensory and motor functions. Sensory functions include providing sensation to the face, sinuses, and teeth. Motor functions include controlling the muscles used for chewing (mastication).
C. II
Cranial Nerve II is the Optic Nerve. It is purely a sensory nerve responsible for vision. The optic nerve carries visual information from the retina of the eye to the brain.
D. III
Cranial Nerve III is the Oculomotor Nerve. It is primarily a motor nerve but also has some autonomic functions. It controls most of the eye movements (except lateral movement controlled by VI) and regulates the size of the pupil and the shape of the lens in the eye for focusing.

Correct Answer is A
Explanation
A. Atelectatic crackles that do not have a pathologic cause:
Atelectatic crackles are short, popping, crackling sounds heard during auscultation. They occur in individuals who are in a supine position and disappear after a few breaths. These crackles are not indicative of any pathological condition; they are common when the lungs are not fully aerated, especially when a person is lying down.
B. Vesicular breath sounds:
Vesicular breath sounds are normal lung sounds heard over the peripheral lung areas. They are soft, low-pitched, and continuous throughout inspiration and part of expiration. Vesicular breath sounds are the typical sounds heard during routine breathing and are not associated with crackling or popping noises.
C. Fine wheezes:
Wheezes are high-pitched whistling sounds heard during expiration. They occur due to narrowed airways and are commonly associated with conditions like asthma or bronchoconstriction. Fine wheezes suggest a partial obstruction in the smaller airways, causing turbulent airflow, leading to the characteristic sound.
D. Fine crackles and may be a sign of pneumonia:
Fine crackles are high-pitched, discontinuous, crackling sounds heard during inspiration. They can occur due to the sudden opening of small airways, and their presence may indicate fluid in the lungs or lung inflammation. Fine crackles are often associated with conditions such as pneumonia, heart failure, or interstitial lung diseases.
Correct Answer is C
Explanation
A. Checks the instrument gauge to ensure the reading starts at zero:
This action is correct. Before taking a blood pressure reading, it's essential to ensure that the instrument's gauge starts at zero. This ensures accurate measurement as the reading reflects the pressure above zero.
B. Centers the cuff bladder over the client's brachial artery:
This action is correct. Proper placement of the blood pressure cuff over the brachial artery is crucial for accurate readings. Centering the cuff ensures that the artery is correctly compressed for measurement.
C. Places the client's arm above the level of the client's heart:
This action is incorrect. Placing the arm above heart level can result in a falsely low blood pressure reading. The arm should be at the same level as the heart to obtain an accurate measurement.
D. Wraps the blood pressure cuff around the client's arm using firm pressure:
This action is correct, but it's important to note that while the cuff should be snug, it should not be too tight or too loose. Wrapping the cuff with firm, even pressure ensures proper compression of the artery for an accurate measurement.
