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. Reminding the UAP to continue rubbing the hands together until they are dry ensures proper use of the hand rub, which is effective when fully dry.
B. Handwashing with soap and water is necessary after certain activities (e.g., after using the restroom, or when hands are visibly soiled), but using an alcohol-based hand rub is appropriate for routine hand hygiene.
C. Supervising in the next client's room is less direct and immediate than ensuring proper technique now.
D. Wearing gloves for all clients is not necessary and does not replace proper hand hygiene.

A. Oxygen saturation 98% on room air B. Urine output 20 mL in the last hour C. Basilar crackles D. Heart rate 72 beats/minute E. Respiratory rate 26 breaths/minute F. Blood pressure 126/76 mm Hg G. Electrocardiogram Tall T wave and widened QRS complex H. Temperature 98.9° F (37.1° C) orally

Correct Answer is ["A","D","E","F","H"]

Explanation

A. Oxygen saturation of 98% on room air indicates that the client is maintaining adequate oxygenation without the need for supplemental oxygen.
B. A urine output of 20 ml within the last one hour is insufficient and could indicate an acute kidney injury.
C. Presence of crackles indicates ongoing pulmonary involvement, which does not suggest stabilization.
D. A heart rate within the normal range for a 7-year-old child (70-120 beats/minute), showing improvement from the previously irregular and elevated rate.
E. Respiratory rate of 26 breaths/minute is now within the normal range for a child (20-30 breaths/minute), indicating improved respiratory function.
F. A blood pressure of 126/76 mm Hg is within the normal range for a child.

G. Tall T wave and widened QRS complex suggest hyperkalemia, which is a serious condition and does not indicate stabilization.
H. An oral temperature of 37.1 C Indicates that the fever has resolved, suggesting that the infection or inflammatory response is under control.
