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.

The employee health nurse is teaching a class on 'Preventing Eye Injury.' Which information should be discussed in the class?
- A. Read instructions thoroughly before using tools and working with chemicals.
- B. Wear some type of glasses when working around flying fragments.
- C. Always wear a protective helmet with eye shield around dust particles.
- D. Pay close attention to the surroundings so eye injuries will be prevented.
Correct Answer: A
Rationale: Reading instructions ensures safe tool and chemical use, preventing eye injuries. Glasses are specific, helmets are not always required, and attention is vague.
The client has a hearing loss from a possible acoustic neuroma. The nurse should prepare the client for which diagnostic test to confirm the presence of a tumor?
- A. Tympanometry
- B. Arteriogram of the cranial vessels
- C. Magnetic resonance imaging (MRI)
- D. Auditory canal biopsy
Correct Answer: C
Rationale: MRI with gadolinium enhancement is the most reliable test in determining size and anatomical location of an acoustic neuroma. Tympanometry, arteriogram, and biopsy are not used for this diagnosis.
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.
An adult is being treated with phenytoin (Dilantin) for a seizure disorder. Five days after starting the medication, he tells the nurse that his urine is reddish-brown in color. What action should the nurse take?
- A. Inform him that this is a common side effect of phenytoin (Dilantin) therapy
- B. Test the urine for occult blood
- C. Report it to the physician because it could indicate a clotting deficiency
- D. Send a urine specimen to the lab
Correct Answer: A
Rationale: Phenytoin commonly causes reddish-brown urine, a benign side effect, so informing the client is appropriate. Testing or reporting is unnecessary unless other symptoms suggest a problem.
The nurse is assessing the older adult client with otosclerosis. Which diagnostic characteristics should the nurse associate with otosclerosis?
- A. Bone conduction is greater than air conduction.
- B. Hearing aids are not effective in restoring hearing.
- C. Surgical restoration of hearing is not possible.
- D. Serial audiograms show progressive hearing loss.
Correct Answer: A
Rationale: Otosclerosis impairs the air conduction of sound waves; therefore, bone conduction is typically greater than air conduction. Hearing aids and surgical restoration (stapedectomy) are effective, and progressive hearing loss is detected by serial audiograms.
