SECTION ONE: QUESTIONS 1–100
1. Which organelle is primarily responsible for the synthesis of adenosine
triphosphate (ATP) through cellular respiration?
A. Nucleus
B. Ribosome
🟢 C. Mitochondria
D. Lysosome
🔴 RATIONALE: Mitochondria are known as the powerhouses of the cell because
they convert biochemical energy from nutrients into ATP via oxidative
phosphorylation.
2. A patient is prescribed a medication that must be diluted. If 5 mL of medication
is added to 45 mL of saline, what is the ratio of medication to total volume?
A. 1:5
🟢
B. 1:10
,C. 1:9
D. 5:45
🔴 RATIONALE: The total volume is 5 mL + 45 mL = 50 mL. The ratio of medication
(5) to total volume (50) simplifies to 1:10.
3. Which of the following terms is most nearly opposite in meaning to the word

4. In the human circulatory system, which vessel carries deoxygenated blood from
the heart to the lungs?
A. Aorta
B. Pulmonary vein
, 🟢 C. Pulmonary artery
D. Superior vena cava
🔴 RATIONALE: The pulmonary artery is unique because it carries deoxygenated
blood away from the right ventricle to the lungs for oxygenation.
5. A nurse observes an apical pulse of 110 beats per minute. Which medical term
correctly describes this finding?
A. Bradycardia
🟢 B. Tachycardia
C. Hypertension
D. Eupnea
🔴 RATIONALE: Tachycardia refers to a heart rate that exceeds the normal resting
rate, typically defined as over 100 beats per minute in adults.
6. If a solution has a pH of 3, how would it be classified?
A. Strong base
🟢 B. Acidic
C. Neutral
D. Alkaline
