Answer and Explanation

The Correct Answer is {"A":{"answers":"A"},"B":{"answers":"D"},"C":{"answers":"B"},"D":{"answers":"C"}}

Macular degeneration: This condition leads to the loss of central vision due to damage to the macula, which is responsible for sharp, straight-ahead vision.

Presbyopia: A common age-related condition resulting in a gradual loss of near visual acuity as the lens becomes less flexible, making it harder to focus on close objects.

Glaucoma: Typically causes loss of peripheral vision due to increased intraocular pressure damaging the optic nerve, eventually leading to tunnel vision if untreated.

Cataracts: Causes blurry vision as the lens becomes clouded, leading to general visual disturbance that progresses over time.

Correct Answer is C

Explanation

A. Penicillins are generally safe but are not specific for ototoxicity considerations.

B. Aminoglycosides are avoided in cases of tympanic membrane rupture due to their ototoxic potential, which can lead to hearing loss.

C. Fluoroquinolones, particularly those formulated for otic use, are preferred for tympanic membrane ruptures as they are not ototoxic and are safe for middle ear exposure.

D. Cephalosporins are not typically ototoxic but are less commonly used for tympanic membrane ruptures compared to fluoroquinolones.

Correct Answer is ["16"]

Explanation

To calculate the dosage of Vancomycin, first convert the patient's weight from pounds to kilograms, knowing that 1 kg equals 2.2 lbs. The patient weighs 110 lbs, which is equivalent to 50 kg (110 lbs / 2.2). Next, multiply the patient's weight in kilograms by the prescribed dosage of 20 mg/kg, resulting in a total dosage of 1000 mg (50 kg * 20 mg/kg). Since the vials contain 500 mg per 8 mL, divide the total dosage required by the amount per vial to find out how many milliliters should be withdrawn. This results in 16 mL (1000 mg / (500 mg/8 mL)).
