Section One: Questions 1–100
1. Which of the following organelles is responsible for the production of adenosine
triphosphate (ATP) in a eukaryotic cell?
A. Lysosome
B. Ribosome
C. Mitochondrion
D. Golgi apparatus
Explanation: Mitochondria are known as the powerhouse of the cell because they
conduct aerobic respiration to produce ATP.
, 2. A patient presents with a blood pressure reading of 145/95 mmHg. How is this blood
pressure categorized?
A. Hypertension
B. Hypotension
C. Normal range
D. Pre-hypertension
Explanation: Hypertension is defined as a blood pressure reading consistently above
130/80 mmHg.
3. Which organ system is primarily responsible for the regulation of blood pH levels
through the excretion of hydrogen ions?
A. Circulatory system
B. Digestive system
C. Urinary system
D. Endocrine system
Explanation: The kidneys regulate blood pH by excreting hydrogen ions and reabsorbing
bicarbonate.
4. What is the value of 15% of 250?
A. 30.5
B. 32.5
C. 37.5
D. 40.5
Explanation: 0.15 multiplied by 250 equals 37.5.
5. Which of the following describes the role of an enzyme in a chemical reaction?
A. It is consumed by the reaction
B. It lowers the activation energy
C. It increases the activation energy
D. It changes the equilibrium point
Explanation: Enzymes act as catalysts to speed up reactions by lowering the activation
energy required.
, 6. In a research study, which variable is manipulated by the investigator?
A. Dependent variable
B. Controlled variable
C. Extraneous variable
D. Independent variable
Explanation: The independent variable is the factor the researcher changes to observe
an effect.
7. Which of the following is an example of a chemical change?
A. Melting ice
B. Boiling water
C. Burning wood
D. Shredding paper
Explanation: Burning wood creates new substances through combustion, which is a
chemical change.
8. A nurse observes a colleague violating a patient's privacy. According to professional
standards, what is the first action?
A. Ignore the behavior
B. Discuss it with other staff
C. Report the violation through proper channels
D. Confront the patient
Explanation: Ethical standards require reporting breaches of patient confidentiality to
ensure safety and compliance.
9. Which blood vessel carries oxygenated blood from the lungs to the heart?
A. Pulmonary vein
B. Pulmonary artery
C. Superior vena cava
D. Aorta
Explanation: The pulmonary veins return oxygenated blood from the lungs to the left
atrium of the heart.
, 10. What is the sum of 1/4 and 1/3?
A. 2/7
B. 7/12
C. 1/7
D. 5/12
Explanation: Finding a common denominator (12), 3/12 + 4/12 equals 7/12.
11. Which structure in the respiratory system is the site of gas exchange?
A. Trachea
B. Bronchi
C. Alveoli
D. Larynx
Explanation: Alveoli are tiny air sacs where oxygen enters and carbon dioxide leaves the
blood.
12. Which of the following is a physical property of matter?
A. Flammability
B. Density
C. Reactivity
D. Toxicity
Explanation: Density is a measurable physical property that does not change the
chemical identity of the substance.
13. A patient is prescribed 500mg of medication. The stock available is 250mg per tablet.
How many tablets should the patient receive?
A. 1
B. 2
C. 3
D. 0.5
Explanation: Dividing the ordered dose (500mg) by the strength per tablet (250mg)
results in 2 tablets.
14. What describes the process of osmosis?
