- A. a deficiency of dopamine in the brain.
- B. a demyelinating process affecting the central nervous system.
- C. atrophy of the basal ganglia.
- D. insufficient uptake of acetylcholine in the body.
Correct Answer: A
Rationale: Parkinson's disease is caused by a deficiency of dopamine in the brain, leading to motor symptoms.

The 60-year-old client notices a gradual decline in visual acuity and asks if it could be from a cataract. Which question will help determine whether a cataract is developing?
- A. Has your ability to perceive colors changed?
- B. Does your vision appear distorted or wavy?
- C. Does the center of your visual field appear dark?
- D. Do you see random flashes of bright light?
Correct Answer: A
Rationale: Asking about a change in the ability to perceive colors will help in determining cataract development. Cataract formation involves the lens of the eye becoming more opaque, thus decreasing the vibrancy of colors. Distorted central vision is a sign of macular degeneration. A darkened area in the center of the visual field is associated with macular degeneration. Seeing flashes of bright lights is associated with retinal detachment.
Which assessment technique should the nurse implement when assessing the client's cranial nerves for vibration?
- A. Move the big toe up and down and ask in which direction the vibration is felt.
- B. Place a tuning fork on the big toe and ask if the vibrations are felt.
- C. Tap the client's cheek with the finger and determine if vibrations are felt.
- D. Touch the arm with two sharp objects and ask if one (1) vibration or two (2) is felt.
Correct Answer: B
Rationale: Placing a tuning fork on the big toe assesses vibration sense (via dorsal column pathways), not cranial nerves directly, but is the correct technique. Other options assess different sensations.
A young man was swimming at the beach when an exceptionally large wave caused him to be drawn under the water. His family members found him in the water and pulled him ashore. He states that he heard something snap in his neck. When a nurse arrives, he is conscious and lying on his back. He states that he has no pain. He is unable to move his legs. How should he be transported?
- A. Position him in a prone position and place on a backboard.
- B. Apply a neck collar and position supine on a backboard.
- C. Log roll him to a rigid backboard.
- D. Position in an upright position with a firm neck collar.
Correct Answer: B
Rationale: A suspected neck injury requires immobilization with a neck collar and supine positioning on a backboard to prevent further spinal cord damage.
The nurse is assessing the client’s sensory system. Which assessment data indicate an abnormal stereognosis test?
- A. The client is unable to identify which way the toe is being moved.
- B. The client cannot discriminate between sharp and dull objects.
- C. The toes contract and draw together when the sole of the foot is stroked.
- D. The client is unable to identify a key in the hand with both eyes closed.
Correct Answer: D
Rationale: Abnormal stereognosis is the inability to identify objects (e.g., a key) by touch with eyes closed, indicating parietal lobe dysfunction. Toe movement, sharp/dull, and Babinski reflex test other functions.
The nurse completed teaching the client with a corneal abrasion about proper care of the injury. Which statements indicate that the client understood the teaching? Select all that apply.
- A. I should promptly report a sudden absence of pain.
- B. I should keep my affected eye uncovered when up.
- C. I should insert the eye drops 10 to 15 seconds apart.
- D. I should leave the eye patch in place for 24 hours.
- E. I will avoid rubbing my affected eye or the eye patch.
Correct Answer: D,E
Rationale: Patching the eye for 24 hours reduces irritation and promotes healing. Avoiding rubbing prevents reinjury. Sudden absence of pain, keeping the eye uncovered, and short intervals between drops are incorrect.
