The nurse is preparing to administer a suspension ampicillin labeled, 250 mg/5 mL, to a child with impetigo. The prescription is for 500 mg four times a day. How many mL should the child receive per day?
(Enter numeric value only.)
The Correct Answer is ["40"]
To determine the amount of mL the child should receive per day, we need to calculate the total daily dose of ampicillin based on the prescription.
The prescription is for 500 mg of ampicillin four times a day, so the total daily dose is: 500 mg × 4 times = 2000 mg/day
The concentration of the suspension is 250 mg/5 mL, which means that there are 250 mg of ampicillin in every 5 mL.
To find out how many mL the child should receive per day, we divide the total daily dose by the concentration:
2000 mg ÷ 250 mg/5 mL = 40 mL/day
Therefore, the child should receive 40 mL of the ampicillin suspension per day.

Correct Answer is ["1.4"]
Explanation
Calculate the total dosage required: 44 mcg/kg * 65 kg = 2860 mcg. Convert mcg to mg: 2860 mcg ÷ 1000 = 2.86 mg.
Divide by concentration: 2.86 mg ÷ 2 mg/mL = 1.43 mL.
Considering the vial contains 2 mg/mL, the nurse should administer around 1.43 mL, which can be rounded to 1.4 mL.
Correct Answer is D
Explanation
A) Incorrect- Dullness bilaterally on percussion is not a normal finding, but it is not an immediate concern after thoracentesis. It may indicate fluid accumulation or consolidation in both lungs, which could be related to other conditions such as pneumonia or heart failure.
B) Incorrect- Serosanguinous drainage from the chest tube is expected after thoracentesis, as long as it is not excessive or continuous. The nurse should monitor the amount and color of the drainage and document it accordingly.
C) Incorrect- Diminished breath sounds in the left lower lobe are also expected after thoracentesis, as the procedure removes fluid and air from the pleural space and reduces lung expansion. The nurse should auscultate the lungs before and after the procedure and compare the findings. The breath sounds should improve gradually as the lung re-expands.
D) Correct- This is a sign of tension pneumothorax, which is a life-threatening complication of thoracentesis. Tension pneumothorax occurs when air accumulates in the pleural space and creates positive pressure that pushes the mediastinum (the heart, great vessels, and trachea) to the opposite side of the chest. This can impair venous return, cardiac output, and respiratory function. The nurse should report this finding to the healthcare provider immediately and prepare to assist with needle decompression or chest tube insertion.
