A nurse is collecting data about a client's cranial nerves. Which of the following methods should the nurse use to identify a problem with cranial nerve II?
Assess the 6 cardinal gazes
Ask the client to her clench teeth.
Anticipate the use of a tonometer
Use a Snellen chart.
The Correct Answer is D
a) Assess the 6 cardinal gazes: This test assesses cranial nerve III, IV, and VI (oculomotor, trochlear, and abducens), which control eye movement, not the optic nerve.
b) Ask the client to clench teeth: This tests cranial nerve V (trigeminal nerve), which controls sensation in the face and motor functions like chewing.
c) Anticipate the use of a tonometer: A tonometer measures intraocular pressure (IOP), which is related to glaucoma, but it does not specifically assess cranial nerve II.
d) Use a Snellen chart: The Snellen chart is used to test visual acuity, which evaluates the function of cranial nerve II (optic nerve).

Correct Answer is B
Explanation
a) Decreasing viscosity of the tears and allowing fluid to drain away from the eye: This is incorrect. Osmotic agents do not act by affecting the viscosity of tears or enhancing drainage.
b) Increasing plasma osmolarity and drawing extracellular fluid into the blood: Osmotic agents, like mannitol, work by increasing plasma osmolarity, which draws excess fluid from the eye into the bloodstream, thereby lowering intraocular pressure.
c) Blocking production of aqueous humor: This is incorrect. Blocking production of aqueous humor is the mechanism of action of medications like beta-blockers (e.g., timolol), not osmotic agents.
d) Promoting outflow of the aqueous humor into the tear ducts: This is incorrect. Promoting outflow of aqueous humor is the mechanism of action for other medications, such as prostaglandin analogs, not osmotic agents.
Correct Answer is A
Explanation
a) Bradycardia: Timolol, a beta-blocker, can cause bradycardia when absorbed systemically.
b) Hypertension: Timolol typically lowers blood pressure rather than increasing it.
c) Anemia: Timolol does not affect red blood cell production.
d) Seizures: Seizures are not associated with timolol use.
