A dehydrated child has intravenous aid therapy ordered. The child weighs 10 kg. Physician ordered Lactated Ringer's solution 40 ml/kg over 4 hours How many miles per hour will this child receive?

300ml/hour

100 mL/hour

50mL/hour

200 ml/hour

Answer and Explanation

The Correct Answer is B

Infusion rate (mL/hour) = Total volume (mL) / Total time (hours)

Given:

Child's weight: 10 kg

Ordered volume: 40 mL/kg

Total time: 4 hours

First, calculate the total volume of Lactated Ringer's solution needed:

Total volume = 40 mL/kg × 10 kg = 400 mL

Then, divide the total volume by the total time to find the infusion rate:

Infusion rate = 400 mL / 4 hours = 100 mL/hour

Correct Answer is D

Explanation

A. Instruct the client to cough. Coughing is generally encouraged after chest physiotherapy to help expel loosened secretions, but it is not the first action. The bronchodilator should be administered first to maximize the effectiveness of the chest physiotherapy.

B. Perform vibration while the client exhales slowly through the nose. Vibration is a component of chest physiotherapy used to help loosen secretions during exhalation, but it is performed after the bronchodilator is administered and once the client is positioned properly.

C. Percuss the upper posterior chest.Percussion helps to mobilize secretions but is typically done after the bronchodilator has been administered to allow for more effective airway clearance.

D. Administer albuterol by nebulizer.Administering albuterol first dilates the airways, making it easier to mobilize and clear secretions during percussion, vibration, and postural drainage.

Correct Answer is ["5.4"]

Explanation

Convert the child's weight from pounds (lb) to kilograms (kg):

20 lb × (1 kg / 2.20462 lb) ≈ 9.07 kg

Calculate the total daily dose of cefazolin:

Total daily dose = 30 mg/kg/day × 9.07 kg = 272.1 mg/day

Divide the total daily dose into two equal doses:

Each dose = 272.1 mg / 2 ≈ 136.05 mg

Determine the dose per ml using the available oral suspension concentration:

125 mg/5 ml = 25 mg/ml

Calculate the volume of oral suspension needed for each dose:

Volume per dose = Dose per dose / Concentration per ml

≈ 136.05 mg / 25 mg/ml

≈ 5.44 ml

So, the child should receive approximately 5.44 ml per dose of cefazolin oral suspension.
