Which statement best describes the scientific rationale for the nurse holding the otoscope with the hand in a pencil-hold position when examining the client's ear?

- B. This allows the best visualization of the tympanic membrane.
- C. This prevents inserting the otoscope too far into the external ear.
- D. It ensures the nurse will not cause pain when examining the ear.
Correct Answer: C
Rationale: The pencil-hold prevents deep insertion, protecting the ear canal and tympanic membrane. Comfort, visualization, and pain avoidance are secondary.

- A. Corneal dystrophy.
- B. Conjunctivitis.
- C. Diabetic retinopathy.
- D. Cataracts.

- D. Sodium fluoride causes the production of histamine and increases the fluid in the ear.
Correct Answer: A
Rationale: The medication, sodium fluoride, retards bone reabsorption (prevents the breakdown of bone cells) and promotes calcification (hardening) of the bony lesions in the ear.
