An infant who weighs 22 lb receives a prescription for amoxicillin 20 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 necessary, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["1.3"]

To calculate the dosage of amoxicillin for the infant, first convert the weight from pounds to kilograms, knowing that 1 kilogram equals 2.2 pounds. The infant weighs 22 pounds, which is equivalent to 10 kilograms (22 lb / 2.2 lb/kg). The prescription is for 20 mg/kg/day, so the total daily dosage is 200 mg (10 kg * 20 mg/kg). This total daily dosage is divided into three doses, as it is to be administered every 8 hours, resulting in

66.7 mg per dose (200 mg / 3). The medication is supplied as 250 mg per 5 mL, so to find out how many mL per dose, set up a proportion: 250 mg is to 5 mL as 66.7 mg is to X mL. Solving for X gives us 1.334 mL (66.7 mg * 5 mL / 250 mg), which rounds to 1.3 mL when rounded to the nearest tenth.

Correct Answer is A

Explanation

A. An aPTT that is 2 times the control value indicates that the heparin is effectively anticoagulating the blood, which is a desired outcome in managing MI to prevent clot formation.
B. S3 heart sounds can indicate heart failure and are not a sign of a satisfactory response to MI treatment.
C. Wide Q waves indicate a previous infarction but do not reflect the immediate effectiveness of the treatment.
D. A positive guaiac test indicates gastrointestinal bleeding, which is a potential complication rather than a satisfactory response.

A. Increase fluid intake to 3,000 mL/daily. B. Provide frequent rest periods. C. Administer O2 at 5 L/minute per nasal cannula. D. Maintain the client in a semi-Fowler's position.

Correct Answer is A

Explanation

A. Increasing fluid intake helps thin pulmonary secretions, making them easier to expectorate and is most directly related to clearing the airway.
B. Providing frequent rest periods is important but does not directly clear the airway.

C. Administering O2 addresses hypoxia but does not clear secretions.

D. Semi-Fowler's position helps with breathing but does not specifically address thick secretions.
