A client who weighs 22 pounds receives a prescription for amoxicillin 50 mg/kg/day PO in divided doses every 8 hours. The bottle is labeled "Amoxicillin for Oral Suspension, USP 250 mg per 5 mL." How many mL should the nurse administer with each dose?

(Enter numerical value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["3.3"]

Calculation Steps:

Step 1: Convert weight from pounds to kilograms: 22 pounds ÷ 2.2 = 10 kg. Result = 10 kg.

Step 2: Calculate the total daily dose of amoxicillin: 50 mg/kg/day × 10 kg = 500 mg/day. Result = 500 mg/day.

Step 3: Calculate the dose per administration: 500 mg/day ÷ 3 doses/day = 166.7 mg/dose. Result = 166.7 mg/dose.

Step 4: Determine how many mL are needed for each dose: 250 mg/5 mL = 50 mg/mL, 166.7 mg ÷ 50 mg/mL = 3.3 mL. Result = 3.3 mL.

Correct Answer is D

Explanation

Choice A reason: Systemic inflammatory response is more characteristic of rheumatoid arthritis rather than osteoarthritis.

Choice B reason: Infectious process in the synovial fluid suggests septic arthritis, not osteoarthritis.

Choice C reason: Loss of bone mineral density is related to osteoporosis, not specifically to osteoarthritis.

Choice D reason: Osteoarthritis is characterized by the destruction of joint cartilage, leading to pain and stiffness in the affected joints.

A. Inject exenatide within 30 minutes before or after a meal. B. Notify your healthcare provider if you start having abdominal pain. C. Exenatide acts in the same way as insulin in lowering blood glucose. D. There are no precautions about taking exenatide with other medications.

Correct Answer is B

Explanation

Choice A reason: Exenatide should be administered within 60 minutes before the morning and evening meals, not within 30 minutes before or after a meal.

Choice B reason: Notifying the healthcare provider if abdominal pain occurs is important because exenatide can cause pancreatitis, and abdominal pain may be a symptom of this condition.

Choice C reason: Exenatide does not act in the same way as insulin. It is an incretin mimetic that enhances glucose-dependent insulin secretion, among other actions.

Choice D reason: There are precautions when taking exenatide with other medications, especially those that affect blood glucose levels, so this statement is incorrect.
