2.Easy
Practice exercise (made-up values, not clinical guidance). Convert 750 mL to L: find x.
750 mL1 L = 1000 mL
x = L
3.Medium
Practice exercise (made-up values, not clinical guidance). A dose calculation for an injection gives 1.8577 mL. The rule in this exercise is that volumes of 1 mL or more are rounded to the nearest tenth of a mL. What value x do you record?
1.8577 mL
x = mL
4.Medium
Practice exercise (made-up values, not clinical guidance). A drip-rate calculation gives 182.963 gtt/min. The rule in this exercise is that drip rates are rounded to the nearest whole drop. What value x do you record?
182.963 gtt/min
x = gtt/min
5.Hard
Practice exercise (made-up values, not clinical guidance). An infusion delivers 10 mg/h. Express this dose rate D in mcg/min. Round to one decimal place.
10 mg/h1 mg = 1000 mcg1 h = 60 min
D = mcg/min
6.Hard
Practice exercise (made-up values, not clinical guidance). A prescription reads 1 tbsp of an oral suspension four times a day for 7 days. The suspension comes in 50 mL bottles. Using 1 tbsp = 15 mL, how many whole bottles N must be supplied so the course is complete?
1 tbspfour times a day7 days50 mL1 tbsp = 15 mL
N =
Answer key
- 1. x = 100 mg
- 2. x = 0.75 L
- 3. x = 1.9 mL
- 4. x = 183 gtt/min
- 5. D = 166.7 mcg/min
- 6. N = 9
