An infant who weighs 22 pounds receives a prescription for amoxicillin 20 mg/kg/day by mouth 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"]

1. Convert the infant's weight from pounds to kilograms. We can use the conversion factor 1 kg

= 2.2 lb. So, 22 lb x (1 kg / 2.2 lb) = 10 kg.

2.   Calculate the total daily dose of amoxicillin for the infant. We can use the formula D = d x W, where D is the total daily dose, d is the dose per kg per day, and W is the weight in kg. So, D = 20 mg x 10 kg = 200 mg.
3.   Calculate the single dose of amoxicillin for the infant. We can divide the total daily dose by the number of doses per day. Since the prescription is for every 8 hours, there are 3 doses per day. So, 200 mg / 3 = 66.67 mg.
4.   Calculate the volume of amoxicillin suspension for the single dose. We can use the ratio of the concentration of the suspension, which is 250 mg per 5 mL. So, 66.67 mg x (5 mL / 250 mg) =
1.33 mL.
5.   Round the volume to the nearest tenth= 1.3 mL

Correct Answer is ["A","B","C","E"]

Explanation

A) Correct- Assessing the child's pulse helps determine their cardiac status and whether they have a detectable heartbeat. This information is essential for deciding the appropriate interventions.
B) Correct- Placing a cervical collar is necessary if there is any suspicion of cervical spine injury due to the fall or submersion. This action helps stabilize the neck and prevent further damage to the spine.
C) Correct- Checking for open wounds is important to assess for potential sources of bleeding or infection that may require immediate attention.
D) Incorrect- While child safety is important, the immediate priority in this situation is assessing and stabilizing the child's medical condition. Child protective services may be involved later if there are concerns about the circumstances surrounding the incident.
E) Correct- Assessing the airway is of utmost importance to ensure that the child can breathe. In cases of near-drowning, ensuring a clear airway is crucial for oxygenation.
F) Incorrect- While establishing intravenous access may be important for certain interventions, it is not one of the immediate priorities in this situation. Ensuring the child's airway, breathing, and circulation take precedence.

Correct Answer is ["25"]

Explanation

The prescription is for 1 gram of azithromycin, which is 1000 mg. The concentration of

the suspension is 200 mg per 5 mL. To calculate the amount in mL:

1000 mg / 200 mg per 5 mL = 25 mL

The nurse should administer 25 mL of the suspension.
