The physician has ordered Amoxicillin 25mg/kg/day in 2 equally divided doses for a client weighing 70 kilograms. The supply of Amoxicillin is 125mg/5ml.
Calculate the correct dosage for one dose in milliliters. Round to the nearest whole number.
Use a leading zero if it applies. Do not use a trailing zero.
The Correct Answer is ["35 "]
Step 1 is to calculate the total daily dosage in milligrams. This is done by multiplying the weight of the client by the ordered daily dosage. So, 70 kg × 25 mg/kg = 1750 mg/day.
Step 2 is to divide the total daily dosage by the number of doses per day to get the dosage per dose. So, 1750 mg ÷ 2 = 875 mg/dose.
Step 3 is to calculate the volume of the dose in milliliters. The supply of Amoxicillin is 125 mg/5 mL, which means there are 125 mg of Amoxicillin in every 5 mL. So, to find out how many milliliters contain 875 mg, we set up a proportion: (125 mg / 5 mL) = (875 mg / x mL). Solving for x gives x = (875 mg × 5 mL) ÷ 125 mg = 35 mL. Therefore, the correct dosage for one dose is 35 mL.

Correct Answer is D
Explanation
Choice A rationale
Supporting the right arm with a sling or pillow can help prevent shoulder dislocation, but it may not directly ensure the safety of a patient who has experienced a stroke in the right hemisphere of the brain.
Choice B rationale
While it is true that a patient who has experienced a stroke in the right hemisphere of the brain may exhibit some degree of expressive or receptive aphasia, anticipating this does not directly ensure the patient’s safety.
Choice C rationale
Placing the wheelchair on the client’s left side when transferring him into a wheelchair is a good practice, but it may not directly ensure the safety of a patient who has experienced a stroke in the right hemisphere of the brain.
Choice D rationale
Patients who have experienced a stroke in the right hemisphere of the brain often exhibit impulsiveness and poor judgment. Therefore, providing close supervision can help ensure the patient’s safety.
Correct Answer is B
Explanation
The correct answer is: = b. Prostaglandins
Choice A: Carbonic anhydrase inhibitors: These medications can be used for glaucoma, but they are not typically the first-line treatment due to potential side effects.
Choice B: Prostaglandins (Correct Answer) These are often the preferred initial medication for glaucoma because they are effective at lowering eye pressure, have minimal systemic side effects, and are typically used once daily.
Choice C: Alpha-agonists: These medications can be used as an adjunct to other glaucoma medications but are not usually the first choice due to potential side effects like dry mouth and fatigue.
Choice D: Beta-blockers: While once a common first-line treatment, beta-blockers have been largely replaced by prostaglandins due to potential side effects like slowed heart rate and worsened breathing problems.
