Which ototoxic medication should the nurse recognize as potentially life altering or threatening to the client?
- A. An oral calcium channel blocker.
- B. An intravenous aminoglycoside antibiotic.
- C. An intravenous glucocorticoid.
- D. An oral loop diuretic.
Correct Answer: B
Rationale: Aminoglycosides (e.g., gentamicin) are ototoxic, causing permanent hearing loss, which is life-altering. Calcium channel blockers, glucocorticoids, and loop diuretics are less ototoxic.

The doctor orders a Tensilon test for a woman suspected of having myasthenia gravis. Which statement is true about this test?
- A. A positive result will be evident within one minute of injection of Tensilon if she has myasthenia gravis.
- B. This is of diagnostic value in only 25% of patients with myasthenia gravis.
- C. Administration of Tensilon causes an immediate decrease in muscle strength for about an hour in persons with myasthenia gravis.
- D. Tensilon works by blocking the action of acetylcholine at the myoneural junction.
Correct Answer: A
Rationale: A positive Tensilon test shows increased muscle strength within one minute, confirming myasthenia gravis, as Tensilon enhances acetylcholine activity.
Which assessment technique should the nurse use to assess the client's optic nerve?
- A. Have the client identify different smells.
- B. Have the client discriminate between sugar and salt.
- C. Have the client read the Snellen chart.
- D. Have the client say 'ah' to assess the rise of the uvula.
Correct Answer: C
Rationale: The optic nerve (cranial nerve II) is assessed by visual acuity tests like the Snellen chart. Smells (olfactory), taste (facial/glossopharyngeal), and uvula movement (vagus) involve other nerves.
The nurse is teaching the client who has otitis media. To reduce the risk of recurrent otitis media, which vaccine should the nurse recommend?
- A. Varicella vaccine
- B. Pneumococcal vaccine
- C. Typhoid vaccine
- D. Zoster vaccine
Correct Answer: B
Rationale: Pneumococcal vaccine can reduce the risk of ear infections. Varicella, typhoid, and zoster vaccines prevent other conditions.
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.
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.
