Question 1 of 49 :
A 54 year old client is admitted with an exacerbation of COPD.
The patient weighs 95 kg. The healthcare provider orders theophylline IV per protocol: Loading dose 6 mg/kg. The pharmacy sends you 250 mg/10 ml of theophylline.
Calculate the ml for the loading dose of theophylline.
Correct Answer: 22.8
Step 1 is 95 kg × 6 mg/kg = 570 mg.
Step 2 is (250 mg ÷ 10 mL) = 25 mg ÷ mL.
Step 3 is 570 mg ÷ (25 mg ÷ mL) = 22.8 mL.
Final calculated answer: 22.8 mL.
