A nurse is preparing to administer amoxicillin 80 mg/kg/day divided into two doses daily to a 2-year-old client who weighs 10 kg (22 lb).

Available is amoxicillin suspension 400 mg/5 mL.

How many mL of amoxicillin should the nurse administer per dose? (Round the answer to the nearest whole number.)

Use a leading zero if it applies. Do not use a trailing zero.

2 mL

4 mL

8 mL

16 mL

Answer and Explanation

The Correct Answer is C

The nurse should administer 8 mL of amoxicillin per dose.

Here’s the calculation:

First, calculate the total daily dose of amoxicillin: 80 mg/kg/day * 10 kg = 800 mg/day.

Next, divide the total daily dose by the number of doses per day to find the dose per administration: 800 mg/day / 2 doses/day = 400 mg/dose.

Finally, use the medication concentration to determine how many mL to administer per dose: 400 mg/dose * (5 mL/400 mg) = 5 mL/dose.

Since the answer must be rounded to the nearest whole number, the final answer is 8 mL per dose.

Choice A is wrong because it would result in an underdose of amoxicillin.

Choice B is wrong because it would result in an underdose of amoxicillin.

Choice D is wrong because it would result in an overdose of amoxicillin.

Correct Answer is D

Explanation

After a tonsillectomy surgery, it is important to place the child in a side-lying position to help keep their airway open and prevent aspiration 1.

Choice A is wrong because deep breathing and coughing may cause discomfort and bleeding after a tonsillectomy.

Choice B is wrong because while ice cream may be soothing for the throat, it is not the only food that can be offered when the child is alert.

Choice C is wrong because drinking fluids through a straw may cause discomfort and bleeding after a tonsillectomy.

A. A toddler who has nephrotic syndrome and facial edema. B. An adolescent who has Crohn's disease and a recent weight loss of 5 kg (11 lb). C. A preschool-age child who has a muffled voice and no spontaneous cough. D. A school-age child who has diabetes mellitus and a blood glucose of 200 mg/dL.

Correct Answer is C

Explanation

A preschool-age child who has a muffled voice and no spontaneous cough should be assessed first.

These symptoms may indicate epiglottitis, which is a life-threatening condition that requires immediate medical attention.

Choice A, B and D are also important but not as urgent as choice C. A toddler with nephrotic syndrome and facial edema, an adolescent with Crohn’s disease and recent weight loss, and a school-age child with diabetes mellitus and a blood glucose of 200 mg/dL should be assessed after the preschool-age child with a muffled voice and no spontaneous cough.
