A patient was given 3L of 5% dextrose with tetracycline to be infused for one day.
What is the infusion rate in ml per minute?
What is the infusion rate in mL per hour?
What is the infusion rate in gtt per minute?
3L x 1000mL/1L = 3000mL x 1day/24hrs = 125 ml/hr 125mL/hr x 1hr/60 min = 2 ml/min 1ml = 15 gtt 2.083mL/min x 15gtt/mL = 31 gtt/min
15. The patient needs 30U of insulin, but the available stock is 80U. A. how much of the 80U will be given? 30U : 80U = x : 16 minims 80U (x) = 480U(minims) x = 6 minims B. If the stock is 100U, how much should be given to meet the patient’s needs? 30U : 100U = x : 16 minims 100U (x) = 480U (minims) x = 4.8 minims or 5 minims
How much grams of the solvent or diluent would be used in preparing the said solution?
How many grams of KMnO 4 solution was used to prepare 2 liters of 0.5% solution?
2L x 1000mL/1L x 0.005 = 10g 2000ml – 10ml = 1990mL
22. A. How many mg of NaHCO3 solution would be needed to prepare 40 oz of 1:100 NaHCO3 solution? 40 oz/ 0.01 = 1200000/ 0.01 = 12000 mg B. How many mL of the 1:100 NaHCO3 solution was prepared? (Note: 1 oz = 30 mL) 40 oz (30 ml/1 oz) = 1200 mL
24. The antibiotic in dry form is contained in 10 ml vial. The label written is 2g/5,000,000 units.
a. How much distilled water should be added to prepare the 10 ml solution?
If the desired dose is 1 ml, how many units are there in one dose?
How many mg are there in one dose?
d. If given bid, how long will the prepared solution last? 10ml – 2 g or ml= 8 ml 10ml : 5000000 = 1 ml : x x = 500000 units 10ml = 5 g // 1mL = 200 mg 10ml ÷ 2 = 5 days
25. Methicillin sodium 1.5 g, IM, q12h, daily for 5 days, was prescribed for a systemic infection. 4 g of the medication is available as a powder in vial. Directions state to reconstitute with 5.7 mL of sterile water for injection and shake well. Solution concentration will provide 500 mg/mL.
How many mL of the drug should the patient actually receive per dose?
B. How many mL of the drug should the patient actually receive per day? C. How many mg did the patient actually consume to complete the dosage? 1500 mL x ( mL / 500 mg) = 3 mL 3 mL x 2 = 6 mL 1.5 x 2 x 5 = 15 mL = 15 g = 15000 mg
