A nurse is preparing to administer amoxicillin 30 mg/kg/day in 2 equally divided doses every 12 hr to a toddler who weighs 33 lb. Available is amoxicillin 200 mg/5 mL suspension.

How many mL should the nurse administer per dose?

Answer and Explanation

The Correct Answer is ["5.6"]

Step 1: Convert the toddler’s weight from pounds to kilograms. 1 kg is approximately 2.2 lb. So, 33 lb ÷ 2.2 = 15 kg.

Step 2: Calculate the total daily dose of amoxicillin. The prescribed dose is 30 mg/kg/day. So, 30 mg/kg/day × 15 kg = 450 mg/day.

Step 3: Since the dose is divided into 2 equal doses every 12 hours, each dose will be half of the total daily dose. So, 450 mg/day ÷ 2 = 225 mg/dose.

Step 4: Calculate the volume of the suspension to administer per dose. The available suspension is 200 mg/5 mL. So, (225 mg/dose ÷ 200 mg) × 5 mL = 5.625 mL/dose. Therefore, the nurse should administer approximately 5.6 mL of the amoxicillin suspension per dose.

Correct Answer is ["125"]

Explanation

Step 1 is to understand the question. The patient has been prescribed vancomycin 1 g in 250 mL dextrose 5% (D5W) to be administered over 2 hours via IV intermittent bolus. We need to calculate how many mL/hr the nurse should set the IV pump to deliver.

Step 2 is to calculate the rate. The total volume to be administered is 250 mL and the time for administration is 2 hours. So, the rate is 250 mL ÷ 2 hours = 125 mL/hr.

A. Discard any residual gastric contents. B. Position the patient in a low Fowler’s position. C. Test the pH of the gastric aspirate. D. Warm the feeding solution to body temperature.

Correct Answer is C

Explanation

Choice A rationale

Discarding any residual gastric contents before administering the tube feeding is not necessary and could lead to unnecessary loss of nutrients and electrolytes.

Choice B rationale

Positioning the patient in a low Fowler’s position is not the optimal position for administering a tube feeding. The patient should be in an upright position to reduce the risk of aspiration.

Choice C rationale

Testing the pH of the gastric aspirate is an important step before administering a tube feeding. This helps to verify that the feeding tube is in the stomach and not in the lungs.

Choice D rationale

Warming the feeding solution to body temperature is not necessary and could potentially lead to bacterial growth in the feeding solution.
