1. Mathematics (Fractions, Decimals, Ratios, Proportions, Algebra)
2. Grammar (Parts of speech, sentence structure, punctuation)
3. Vocabulary (General and medical terminology)
4. Reading Comprehension (Main idea, inference, supporting details)
5. Biology (Cellular biology, metabolism, genetics)
6. Chemistry (Atomic structure, periodic table, reactions)
7. Anatomy & Physiology (Organ systems, homeostasis, physiological processes)
1. A nurse is preparing a dosage of medication. The patient needs 0.75 mg, and the concentration
available is 0.5 mg/mL. How many milliliters should be administered?
A. 1.0 mL
B. 1.5 mL
C. 2.0 mL
D. 0.25 mL
CORRECT ANSWER : B
, Rationale: To find the dosage, divide the desired dose (0.75 mg) by the concentration (0.5
mg/mL), which equals 1.5 mL. Options A, C, and D are incorrect based on the calculation $0.75
\div 0.5 = 1.5$.
2. Identify the error in the following sentence: "Between you and I, the patient's condition has
improved significantly since the surgery."
A. The word "between" is used incorrectly.
B. The pronoun "I" should be "me" because it is the object of the preposition.
C. The word "significantly" is a misplaced modifier.
D. The sentence is grammatically correct.
CORRECT ANSWER : B
Rationale: "Between" is a preposition, and objects of prepositions must be in the objective case
(me, not I). Options A, C, and D are incorrect as the preposition use and adverb placement are
appropriate.
3. Which of the following words best describes the term "ephemeral"?
A. Lasting for a long time.
B. Short-lived or fleeting.
C. Extremely expensive.
D. Deeply emotional.
CORRECT ANSWER : B
Rationale: Ephemeral denotes something that lasts for a very short time. Options A, C, and D
define endurance, cost, or emotion, which are unrelated to the definition of ephemeral.
4. A passage describes a protagonist struggling with the decision to leave their hometown. The
author notes, "The train whistle echoed like a final verdict across the empty valley." This
comparison is an example of:
A. Hyperbole.
B. Simile.
C. Metaphor.
, D. Personification.
CORRECT ANSWER : B
Rationale: A simile uses "like" or "as" to compare two unlike things, which is evident in the
comparison of the whistle to a verdict. Options A, C, and D are incorrect because the phrase
does not use direct equation (metaphor), extreme exaggeration (hyperbole), or human traits
(personification).
5. Which organelle is responsible for the production of adenosine triphosphate (ATP) in eukaryotic
cells?
A. Nucleus.
B. Ribosome.
C. Mitochondrion.
D. Endoplasmic reticulum.
CORRECT ANSWER : C
Rationale: Mitochondria are the sites of cellular respiration, which produces the majority of
ATP. Options A, B, and D are incorrect as they relate to genetic control, protein synthesis, and
transport/synthesis respectively.
6. What is the correct electron configuration for a neutral Magnesium (Mg) atom (atomic number
12)?
A. $1s^2 2s^2 2p^4$
B. $1s^2 2s^2 2p^6 3s^2$
C. $1s^2 2s^2 2p^6 3s^1$
D. $1s^2 2s^2 2p^6$
CORRECT ANSWER : B
Rationale: Neutral Magnesium has 12 electrons, which fill shells in order: 2 in 1s, 2 in 2s, 6 in
2p, and 2 in 3s. Options A, C, and D are incorrect as they represent incorrect electron counts or
orbital filling.
7. Which plane of the body divides it into superior and inferior portions?
A. Sagittal.
, B. Frontal (Coronal).
C. Transverse (Horizontal).
D. Midsagittal.
CORRECT ANSWER : C
Rationale: The transverse plane divides the body into top (superior) and bottom (inferior)
halves. Options A, B, and D are incorrect because they divide the body into left/right or
anterior/posterior sections.
8. If a solution has a pH of 3, what can be inferred about the solution?
A. It is basic.
B. It is acidic.
C. It is neutral.
D. It has a high hydroxide ion concentration.
CORRECT ANSWER : B
Rationale: A pH below 7 indicates an acidic solution. Options A, C, and D are incorrect because
basic solutions have a pH above 7, and neutral solutions have a pH of 7.
9. Which part of the brain is primarily responsible for the regulation of heart rate and respiratory
rate?
A. Cerebrum.
B. Cerebellum.
C. Medulla oblongata.
D. Thalamus.
CORRECT ANSWER : C
Rationale: The medulla oblongata contains control centers for vital autonomic functions like
cardiac and respiratory rhythms. Options A, B, and D are incorrect as they control higher
cognitive function, balance, and sensory relay.
10. A patient's weight is 75 kg. How many pounds is this approximately (1 kg = 2.20462 lbs)?
