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: Preparing the client for a CT scan is important for diagnostic purposes but is not the immediate priority in managing severe pain.

Choice B reason: Straining the urine for stones is important for confirming the presence of renal calculi but should be done after managing the acute pain.

Choice C reason: Obtaining a urine specimen for analysis is useful for diagnosing infection or other abnormalities but is secondary to pain management.

Choice D reason: Administering a prescribed opioid analgesic is the first priority to relieve the client's severe pain and provide comfort.

A. Check the client's current fingerstick blood glucose. B. Obtain blood pressure and heart rate. C. Administer a PRN dose of regular insulin. D. Give the client 4 ounces (120 mL) of orange juice. E. Provide the client with 1/2 cup (120 mL) diet carbonated soda.

Correct Answer is ["A","D"]

Explanation

Choice A reason: Checking the client's current fingerstick blood glucose is important to determine if the confusion and weakness are due to hypoglycemia (low blood sugar) or hyperglycemia (high blood sugar).

Choice B reason: Obtaining blood pressure and heart rate is useful for a general assessment but is secondary to assessing blood glucose levels in this scenario.

Choice C reason: Administering a PRN dose of regular insulin is not appropriate without first determining the client's blood glucose level. If the client is hypoglycemic, insulin could worsen the condition.

Choice D reason: Giving the client 4 ounces (120 mL) of orange juice is a quick way to raise blood sugar levels if the client is hypoglycemic.

Choice E reason: Providing diet carbonated soda is not effective for treating hypoglycemia because it does not contain sugar to raise blood glucose levels.
