100% Accurate Questions with Full Expert-
Verified Solutions
1. What is 3/4 + 5/6?
a. 8/10
b. 19/12
c. 9/12
d. 15/24
Correct Answer: b
Expert-Verified Solution: To add fractions, find a common denominator. The least common
multiple of 4 and 6 is 12. Convert: 3/4 = 9/12 (multiply by 3/3), 5/6 = 10/12 (multiply by 2/2).
Then, 9/12 + 10/12 = 19/12. Nursing Relevance: Accurate fraction addition is key for
calculating medication dosages. Verification: 19/12 is improper but valid for multiple-choice
format.
2. Convert 7/8 to a decimal, rounded to the nearest hundredth.
a. 0.87
b. 0.88
c. 0.86
d. 0.89
Correct Answer: b
Expert-Verified Solution: Divide 7 ÷ 8 = 0.875. Round to the nearest hundredth: 0.875 → 0.88
(since 7 ≥ 5). Nursing Relevance: Decimal conversions are used in dosage calculations (e.g.,
0.88 mg). Verification: 0.88 matches the rounded value.
3. What is 15% of 80?
a. 10
b. 12
c. 15
d. 20
, Correct Answer: b
Expert-Verified Solution: Convert 15% to 0.15, then multiply: 0.15 × 80 = 12. Alternatively,
10% of 80 = 8, 5% of 80 = 4, so 15% = 8 + 4 = 12. Nursing Relevance: Percentages are used for
IV fluid concentrations. Verification: 0.15 × 80 = 12.
4. Solve for x: 2x + 5 = 17.
a. 6
b. 7
c. 8
d. 11
Correct Answer: a
Expert-Verified Solution: Subtract 5: 2x + 5 – 5 = 17 – 5 → 2x = 12. Divide by 2: x = 12 ÷ 2 =
6. Nursing Relevance: Algebra solves for unknown dosages in medication formulas.
Verification: 2(6) + 5 = 12 + 5 = 17.
5. A nurse administers 3/5 of a 100 mL IV bag. How many mL are administered?
a. 50 mL
b. 60 mL
c. 70 mL
d. 80 mL
Correct Answer: b
Expert-Verified Solution: Multiply 3/5 × 100 = (3 × 100) ÷ 5 = 300 ÷ 5 = 60 mL. Nursing
Relevance: Fraction calculations ensure accurate IV fluid administration. Verification: 3/5 ×
100 = 60.
6. Convert 2.5 kg to grams.
a. 250 g
b. 2500 g
c. 25 g
d. 25000 g
Correct Answer: b
Expert-Verified Solution: 1 kg = 1000 g, so 2.5 kg = 2.5 × 1000 = 2500 g. Nursing Relevance:
Unit conversions are critical for medication dosing (e.g., mg to g). Verification: 2.5 × 1000 =
2500.
