ACTUAL PRACTICE EXAM 2025
1. The client’s weight is 128 lb. Determine this client’s weight in kg. (Round to
the tenth.)
Set up the equation: X kg = 128 lb / 2.2 lb/kg.
X = .2 = 58.1818.
Round to the tenth: 58.2 kg.
Reassess: If 1 kg = 2.2 lb, 128 lb should be approximately 58.2 kg.
Answer: 58.2 kg
2. The client’s weight is 96 lb. Determine this client’s weight in kg. (Round to
the tenth.)
Set up the equation: X kg = 96 lb / 2.2 lb/kg.
X = .2 = 43.6363.
Round to the tenth: 43.6 kg.
Reassess: If 1 kg = 2.2 lb, 96 lb should be approximately 43.6 kg.
Answer: 43.6 kg
3. The client’s weight is 5 lb 4 oz. Determine this client’s weight in lb. (Round
to the tenth.)
Convert ounces to pounds: X lb = 4 oz / 16 oz/lb.
X = = 0.25.
Round to the tenth: 0.3 lb.
Add remainder: 5 lb + 0.3 lb = 5.3 lb.
Reassess: If 1 lb = 16 oz, 4 oz is 0.25 lb, rounded to 0.3 lb, total 5.3 lb.
Answer: 5.3 lb
, 4. The client’s weight is 21 lb 14 oz. Determine this client’s weight in pounds.
(Round to the tenth.)
Convert ounces to pounds: X lb = 14 oz / 16 oz/lb.
X = = 0.875.
Round to the tenth: 0.9 lb.
Add remainder: 21 lb + 0.9 lb = 21.9 lb.
Reassess: If 1 lb = 16 oz, 14 oz is 0.875 lb, rounded to 0.9 lb, total 21.9 lb.
Answer: 21.9 lb
5. Convert a client’s weight from oz to lb, then from lb to kg. The client’s
weight is 65 lb 12 oz. (Round to the tenth.)
First, ounces to pounds: X lb = 12 oz / 16 oz/lb = 0.75.
Round to the tenth: 0.8 lb.
Total lb: 65 + 0.8 = 65.8 lb.
Then, lb to kg: X kg = 65.8 lb / 2.2 lb/kg = 29.909.
Round to the tenth: 29.9 kg.
Reassess: 12 oz is 0.75 lb (rounded 0.8), total 65.8 lb; 65..2 ≈ 29.9 kg.
Answer: 29.9 kg
6. Convert a client’s weight from oz to lb, then from lb to kg. The client’s
weight is 33 lb 8 oz. (Round to the tenth.)
First, ounces to pounds: X lb = 8 oz / 16 oz/lb = 0.5 lb (no rounding needed).
Total lb: 33 + 0.5 = 33.5 lb.
Then, lb to kg: X kg = 33.5 lb / 2.2 lb/kg = 15.227.
Round to the tenth: 15.2 kg.
Reassess: 8 oz is 0.5 lb, total 33.5 lb; 33..2 ≈ 15.2 kg.
Answer: 15.2 kg
7. The provider has prescribed 100 mg/kg/day. The client’s weight is 69.5 kg.
What is the daily dose of medication you would administer? (Round to a
whole number.)
