A patient is unable to taste in the 2/3 anterior of his tongue. Which cranial nerve is affected?
A. VII
VII: The Facial nerve (VII) is responsible for taste sensation in the anterior two-thirds of the tongue. An inability to taste in this area indicates a dysfunction in this nerve.
B. XII
XII: The Hypoglossal nerve (XII) controls tongue movements but does not involve taste sensation.
C. V
V: The Trigeminal nerve (V) provides sensation to the face and mouth but is not responsible for taste.
D. II
II: The Optic nerve (II) is involved in vision, not taste.

Cranial nerves involved in eye movements are:
A. Facial, Trigeminal, Vestibulocochlear
Facial, Trigeminal, Vestibulocochlear: The Facial nerve (VII) controls facial expressions, the Trigeminal nerve (V) is involved in facial sensation, and the Vestibulocochlear nerve (VIII) handles hearing and balance, none of which are directly related to eye movements.
B. Oculomotor, Trochlear, and Abducens
Oculomotor, Trochlear, and Abducens: The Oculomotor nerve (III) controls most eye movements, the Trochlear nerve (IV) controls the superior oblique muscle for downward and outward movements, and the Abducens nerve (VI) controls the lateral rectus muscle for lateral eye movement.
C. Spinal Accessory, Facial, Trigeminal
Spinal Accessory, Facial, Trigeminal: The Spinal Accessory nerve (XI) controls neck and shoulder movements, while the Facial nerve (VII) and Trigeminal nerve (V) are not involved in eye movements.
D. Glossopharyngeal, Vagus, Hypoglossal
Glossopharyngeal, Vagus, Hypoglossal: The Glossopharyngeal nerve (IX) is involved in taste and salivation, the Vagus nerve (X) affects parasympathetic functions, and the Hypoglossal nerve (XII) controls tongue movements, none of which are related to eye movements.

Data collection occurs where in the nursing process?
A. Planning
Planning: Planning involves setting goals and interventions based on data collected, but data collection itself is not part of this phase.
B. Diagnosis
Diagnosis: Diagnosis involves analyzing collected data to identify health issues, but data collection is a separate process that occurs before this phase.
C. Evaluation
Evaluation: Evaluation assesses the effectiveness of interventions and progress towards goals, but data collection is performed earlier in the process.
D. Assessment
Assessment: Data collection is a fundamental part of the assessment phase in the nursing process, where information is gathered to identify patient needs and conditions.

What eye function is the nurse preparing to assess when the client is asked to stand 20 feet from a specific chart that is mounted on the examination room wall?
A. External Eye Structures
External Eye Structures: This assessment involves examining the visible parts of the eye and surrounding structures, not the distance vision.
B. Near Vision
Near Vision: Near vision is typically assessed using a reading chart held at a close distance, not a chart mounted on the wall.
C. Peripheral Vision
Peripheral Vision: Peripheral vision assessments involve testing the field of vision to detect loss or abnormalities, rather than focusing on distant vision.
D. Distant Vision
Distant Vision: Standing 20 feet from a chart to read letters tests distant vision, as it assesses the ability to see objects clearly at a distance.
