Correct Answer is C

Explanation

a) Ability to contract and relax the dilator muscle: This refers to the iris muscles, but it does not relate directly to the measurement of intraocular pressure (IOP).
b) Resistance from the ciliary bodies: The ciliary body produces aqueous humor, but IOP measures the pressure exerted by the amount of aqueous humor, not resistance from the ciliary bodies.
c) Amount of aqueous humor: IOP is determined by the balance between the production and drainage of aqueous humor within the eye.
d) Tear duct capacity: Tear duct capacity relates to tear drainage, not intraocular pressure.

A. Fever B. Fluid overload C. Bradycardia D. Anaphylaxis

Correct Answer is B

Explanation

a) Fever: Fever is not a common adverse effect of mannitol.
b) Fluid overload: Mannitol is an osmotic diuretic, and while it helps reduce fluid in the brain, it can sometimes lead to fluid retention and overload in other parts of the body.
c) Bradycardia: Bradycardia is not a typical adverse effect of mannitol.
d) Anaphylaxis: Although rare, anaphylaxis is a potential but not common adverse effect of mannitol. It is more likely to cause fluid and electrolyte disturbances.
