INTRODUCTION
This comprehensive assessment is designed to evaluate the essential academic skills necessary for success in
health science fields. The exam measures proficiency in Reading, Mathematics, Science, and English and
Language Usage. It features a blend of foundational theory, professional application, and critical thinking
scenarios designed to simulate the rigorous decision-making required in clinical and academic environments.
By utilizing multiple-choice and scenario-based structures, this tool assesses both core knowledge and the
ability to apply information to real-world problems. This resource serves as a definitive guide for candidates
seeking to demonstrate their readiness for professional health education programs through rigorous,
defensible, and high-quality examination.
1. Which of the following describes the process by which liquid water changes into water vapor?
A. Sublimation
B. Condensation
🟢 C. Evaporation
D. Deposition
🔴 RATIONALE: Evaporation is the phase transition in which a liquid is converted into a gas at temperatures
below the boiling point. Sublimation is solid to gas, condensation is gas to liquid, and deposition is gas to solid.
, 2. A patient is prescribed a medication that requires a dosage of 5 mg per kg of body weight. If the patient
weighs 70 kg, how many mg should they receive?
A. 35 mg
🟢 B. 350 mg
C. 14 mg
D. 700 mg
🔴 RATIONALE: The calculation is 70 kg multiplied by 5 mg/kg, which equals 350 mg.
3. Which of the following cell organelles is responsible for the production of ATP?
A. Ribosome
B. Golgi apparatus
C. Lysosome
🟢 D. Mitochondrion
🔴 RATIONALE: Mitochondria are known as the powerhouses of the cell because they are the primary site of
cellular respiration and ATP (energy) production.
4. Which of the following is the primary function of the large intestine?
🟢 A. Absorption of water
B. Digestion of proteins
C. Absorption of nutrients
D. Storage of bile
🔴 RATIONALE: While the small intestine absorbs most nutrients, the large intestine is primarily responsible for
reabsorbing water and electrolytes from indigestible food matter.
5. Identify the adverb in the following sentence: "The nurse quickly administered the medication to the
patient."
,A. Nurse
🟢 B. Quickly
C. Administered
D. Medication
🔴 RATIONALE: "Quickly" is an adverb because it modifies the verb "administered," describing how the action
was performed.
6. Which valve prevents the backflow of blood from the left ventricle into the left atrium?
🟢 A. Mitral valve
B. Tricuspid valve
C. Pulmonary valve
D. Aortic valve
🔴 RATIONALE: The mitral (or bicuspid) valve is located between the left atrium and left ventricle. The tricuspid
valve is on the right side of the heart.
7. In a study, the variable that is manipulated by the researcher is known as the:
A. Dependent variable
🟢 B. Independent variable
C. Control variable
D. Extraneous variable
🔴 RATIONALE: The independent variable is the factor that is changed or manipulated in an experiment to test
its effects on the dependent variable.
8. What is the sum of 1/4 and 2/5?
A. 3/9
B. 3/20
, 🟢 C. 13/20
D. 7/20
🔴 RATIONALE: To add fractions, find a common denominator (20). 1/4 becomes 5/20 and 2/5 becomes 8/20.
5/20 + 8/20 = 13/20.
9. Which of the following is a characteristic of a chemical change?
A. Change in state
B. Melting
🟢 C. Production of gas
D. Dissolving
🔴 RATIONALE: The production of gas (effervescence) is a common indicator that a chemical reaction has
occurred, resulting in the formation of new substances.
10. Which part of the brain is responsible for regulating heart rate and breathing?
A. Cerebrum
B. Cerebellum
🟢 C. Medulla oblongata
D. Thalamus
🔴 RATIONALE: The medulla oblongata, located in the brainstem, controls vital autonomic functions such as
heart rate, blood pressure, and respiration.
11. Choose the correct spelling to complete the sentence: "The ___________ of the medication was
immediate."
🟢 A. Effect
B. Affect
