What this topic covers

Mathematics: numbers sits inside the Mathematics section of the TEAS 7. Our bank holds 82 verified items tagged to it, and the 4 below are a fixed sample so the page stays the same every time you open it. Each one shows the reasoning, not just the letter.

The topic tag comes from our own items rather than from a published syllabus, so treat it as a map of what we cover. For the official section breakdown see the TEAS 7 page.

Mathematics: numbers sample questions

Question 1

A nurse records a patient's fluid intake over a shift: 240 mL of water, 180 mL of juice, and 120 mL of broth. What is the total fluid intake in milliliters?

  1. A 540
  2. B 530
  3. C 520
  4. D 550
Show the answer and explanation

Correct answer: A

The total is found by adding all amounts: 240 + 180 + 120 = 540 mL. Simple addition yields the correct total intake.

Why the other options are wrong:
B: This could happen if 180 was mistakenly recorded as 170 or if 120 was subtracted instead of added.
C: This would result from incorrectly adding 240 + 180 = 420, then forgetting to add 120 or adding only 100.
D: This would occur if 120 was added twice or if a carry error was made.

Question 2

A patient drank 0.8 liters of water in the morning and 0.35 liters in the afternoon. How many total liters did the patient drink?

  1. A 1.15 L
  2. B 0.115 L
  3. C 0.43 L
  4. D 1.8 L
Show the answer and explanation

Correct answer: A

To find the total, add 0.8 and 0.35. Align the decimals: 0.80 + 0.35 = 1.15 L.

Why the other options are wrong:
B: This is the result of adding 0.8 and 0.35 but misplacing the decimal point (115 → 0.115).
C: This is the result of subtracting 0.35 from 0.8 instead of adding.
D: This is the result of incorrectly adding 0.8 + 0.35 as 0.8 + 1.0 = 1.8, forgetting to add the 0.35 correctly.

Question 3

A nurse needs to administer 0.5 mg of a medication. The vial contains 2 mg/mL. How many mL should the nurse draw up?

  1. A 1 mL
  2. B 0.5 mL
  3. C 0.25 mL
  4. D 4 mL
Show the answer and explanation

Correct answer: C

Use the formula: desired dose ÷ concentration = volume. 0.5 mg ÷ 2 mg/mL = 0.25 mL.

Why the other options are wrong:
A: This results from multiplying rather than dividing.
B: This would be correct if the concentration were 1 mg/mL, but it is 2 mg/mL.
D: This results from inverting the division (2 ÷ 0.5 = 4).

Question 4

Which of the following lists the numbers in order from least to greatest?

  1. A 0.2, 0.15, 0.25, 0.3
  2. B 0.15, 0.25, 0.2, 0.3
  3. C 0.15, 0.2, 0.25, 0.3
  4. D 0.3, 0.25, 0.2, 0.15
Show the answer and explanation

Correct answer: C

To order decimals from least to greatest, compare the digits from left to right. 0.15 (15 hundredths) is smallest, then 0.2 (20 hundredths), then 0.25 (25 hundredths), then 0.3 (30 hundredths).

Why the other options are wrong:
A: This list starts with 0.2, which is not the smallest value.
B: This list places 0.25 before 0.2, which is incorrect because 0.2 is less than 0.25.
D: This list is in descending order (greatest to least).
