1. What is the value of x in the equation 3x - 7 = 14?
A. 5
B. 7
C. 21
D. 63
ANSWER: B. 7
To solve for x, add 7 to both sides of the equation to get 3x = 21, then divide both sides by 3 to
find x = 7. Checking the work: 3(7) - 7 = 21 - 7 = 14, confirming the solution.
2. Which of the following sentences contains a grammatical error in subject-verb
agreement?
A. The group of nurses is attending the conference this weekend.
B. Every student and teacher are required to submit their identification badge.
C. Neither the physician nor the nurses were available during the emergency.
D. The boxes of medical supplies are stored in the back room.
ANSWER: B. Every student and teacher are required to submit their identification badge.
When subjects are joined by "every" or "each", the compound subject is treated as singular,
requiring a singular verb ("is" instead of "are"). Option A is correct because collective nouns
like "group" take singular verbs when acting as a unit.
3. What is 35% of 160?
A. 45
B. 52
C. 56
,D. 64
ANSWER: C. 56
To find 35% of 160, convert the percentage to a decimal (0.35) and multiply it by 160.
Multiplying 0.35 by 160 yields 56. Alternatively, calculate 10% (16), multiply by 3 (48), and
add 5% (8) to get 56.
4. Which of the following anatomical terms describes the front or anterior side of the
human body?
A. Dorsal
B. Ventral
C. Posterior
D. Inferior
ANSWER: B. Ventral
Ventral refers to the belly or front side of the body, which is synonymous with anterior in
human anatomical positioning. Dorsal and posterior refer to the back side, while inferior
refers to a position lower on the body.
5. Convert 7/8 to a decimal value.
A. 0.750
B. 0.825
C. 0.875
D. 0.925
ANSWER: C. 0.875
To convert a fraction to a decimal, divide the numerator by the denominator: 7 divided by 8
equals 0.875. Another method is multiplying numerator and denominator by 125, yielding
875/1000, which equals 0.875.
6. Which of the following words is spelled incorrectly?
A. Accommodate
,B. Necessary
C. Occurence
D. Persistent
ANSWER: C. Occurence
The correct spelling is occurrence, which contains double c and double r. Accommodate,
necessary, and persistent are all spelled correctly according to standard English conventions.
7. If a patient's intravenous fluid infuses at a rate of 125 milliliters per hour, how many
total liters of fluid will the patient receive in 24 hours?
A. 1.5 liters
B. 2.5 liters
C. 3.0 liters
D. 4.5 liters
ANSWER: C. 3.0 liters
Multiply the hourly infusion rate by 24 hours: 125 mL/hr x 24 hr = 3,000 mL. Since 1 liter
equals 1,000 milliliters, divide 3,000 mL by 1,000 to convert to liters, resulting in 3.0 liters.
8. Which cellular organelle is primarily responsible for generating adenosine triphosphate
(ATP) through aerobic cellular respiration?
A. Ribosome
B. Mitochondrion
C. Golgi apparatus
D. Lysosome
ANSWER: B. Mitochondrion
Mitochondria serve as the primary powerhouses of the cell, producing ATP through oxidative
phosphorylation and the citric acid cycle. Ribosomes synthesize proteins, the Golgi apparatus
packages proteins, and lysosomes degrade waste.
9. Solve for y: 4(y - 2) = 3(y + 5)
, A. y = 7
B. y = 15
C. y = 23
D. y = 27
ANSWER: C. y = 23
Distribute the constants on both sides: 4y - 8 = 3y + 15. Subtract 3y from both sides to get y - 8
= 15, then add 8 to both sides to isolate y, yielding y = 23.
10. Which of the following is the correct definition of the medical term "bradycardia"?
A. Abnormally rapid heart rate exceeding 100 beats per minute
B. Abnormally slow heart rate falling below 60 beats per minute
C. Irregular rhythm originating from the atria
D. Complete cessation of cardiac electrical activity
ANSWER: B. Abnormally slow heart rate falling below 60 beats per minute
The prefix "brady-" means slow, and "cardia" refers to the heart, making bradycardia a
resting heart rate slower than 60 beats per minute. Tachycardia refers to a rapid heart rate
exceeding 100 beats per minute.
11. What is the sum of 4.25, 18.9, and 3.007?
A. 25.157
B. 26.157
C. 26.257
D. 27.057
ANSWER: B. 26.157
Line up the decimal points and add the values: 4.250 + 18.900 + 3.007 = 26.157. Proper
alignment of decimal places prevents calculation errors when summing numbers of differing
decimal lengths.
