2.Easy
Practice exercise (made-up values, not clinical guidance). Convert 2.5 mL to tsp, using 1 tsp = 5 mL: how many n? Real liquid doses are always measured in mL, with an oral syringe or a marked medicine cup.
2.5 mL1 tsp = 5 mL
n = tsp
3.Medium
Practice exercise (made-up values, not clinical guidance). A newborn weighs 10 lb 10 oz. Using 1 lb = 16 oz and 1 kg = 2.2 lb, find the weight m in kilograms. Round to two decimal places.
10 lb 10 oz1 lb = 16 oz1 kg = 2.2 lb
m = kg
4.Medium
Practice exercise (made-up values, not clinical guidance). A newborn weighs 4 lb 10 oz. Using 1 lb = 16 oz and 1 kg = 2.2 lb, find the weight m in kilograms. Round to two decimal places.
4 lb 10 oz1 lb = 16 oz1 kg = 2.2 lb
m = kg
5.Hard
Practice exercise (made-up values, not clinical guidance). A serum creatinine result is 108 µmol/L. Using 1 mg/dL = 88.4 µmol/L for creatinine, find c in mg/dL. Round to two decimal places.
108 µmol/L1 mg/dL = 88.4 µmol/L
c = mg/dL
6.Hard
Practice exercise (made-up values, not clinical guidance). An infusion starts at 22:50 and finishes at 01:45 the next morning (24-hour clock). How many hours t did it run? Give the answer in hours as a decimal, rounded to two decimal places.
22:5001:45
t = h
Answer key
- 1. m = 64.1 kg
- 2. n = 0.5 tsp
- 3. m = 4.83 kg
- 4. m = 2.1 kg
- 5. c = 1.22 mg/dL
- 6. t = 2.92 h
