Directions: Calculate the IV medication and infusion rates.Use a calculator for safe dose range calculations,multiplication,and long division as desired.Verify results using DE-style equations where requested.If the order is unsafe,do not proceed with the math.Label answers.
Ordered: aminophylline IV infusion,for a patient with asthma.
Infusing: aminophylline at 33 mL per hr
Available: IV of 500 mL of D5W with the contents of the vial shown here
Patient's weight: 110 kg 
The nurse has withdrawn 20 mL of D5W and added the medication to make a total volume of 500 mL.

B)Evaluation:
Aminophylline
A drug combination that relaxes muscles in the lungs and chest to make breathing easier, used in treating asthma and other airway conditions.
Asthma
A chronic inflammatory disease of the airways in the lungs, characterized by recurrent episodes of wheezing, breathlessness, chest tightness, and coughing.
Infusion Rate
The speed at which liquids, especially drugs or nutrients, are administered intravenously.
- Employ Dimensional Analysis (DA) when calculating dosages for medications and ascertain the correctness of these calculations.
- Assess and modify intravenous medication dosages in response to patient reactions and relevant clinical signs, such as heart rate and blood pressure.
Verified Answer
b.Equation is balanced.Only mg per hour remain.
Note: The equation is solved using the total mL (500 mL)not 20 mL.
