Which is a potential serious adverse effect associated with mannitol (Osmitrol)?
Fever
Fluid overload
Bradycardia
Anaphylaxis
The Correct Answer is B
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.

Correct Answer is A
Explanation
a) A gradual hearing loss that occurs with aging: Presbycusis refers to the age-related gradual decline in hearing, especially in the higher frequencies. It is a common condition that affects older adults due to changes in the inner ear or auditory nerve.
b) Tinnitus that occurs with aging: Tinnitus, which is the perception of ringing or buzzing in the ears, is different from presbycusis. While tinnitus can occur with age, it is not synonymous with presbycusis, which specifically refers to age-related hearing loss.
c) A vision loss that occurs with aging: Vision loss associated with aging is called presbyopia, not presbycusis. Presbyopia is related to the loss of near-vision accommodation, while presbycusis is a hearing loss.
d) Nystagmus that occurs with aging: Nystagmus is an involuntary eye movement that is not specifically related to aging. It can occur in various neurological conditions but is not a hallmark of presbycusis.
Correct Answer is ["A","C","D"]
Explanation
a) Move his or her finger slowly toward the patient's nose: This is an appropriate action for testing accommodation, as it assesses the ability of the eyes to converge and maintain focus on the object as it moves closer.
b) Checking for a nystagmus: This is not directly related to accommodation, though nystagmus can be observed in other assessments for visual and neurological conditions.
c) Assess for convergence: Convergence is part of the accommodation process. It involves the eyes turning inward to focus on a near object.
d) Observe for pupillary constriction: Pupillary constriction is a key part of the accommodation response when focusing on a near object.
e) Note blinking: This is not necessary for assessing accommodation. Blinking can occur for various reasons but is not a direct sign of accommodation.
f) Hold his or her finger approximately 20 inches in front of the patient's eyes: For accommodation testing, the object should be moved closer, typically within 6-8 inches from the eyes.
