Introduction
The ATI TEAS Nursing Entrance Exam serves as a critical standardized assessment designed to evaluate the
academic readiness of prospective nursing students. By focusing on essential content areas including reading,
mathematics, science, and English usage, the exam ensures that candidates possess the foundational skills
necessary for success in rigorous healthcare programs. The assessment utilizes a multiple-choice format
enriched with scenario-based questions that mirror real-world clinical environments. This structure prioritizes the
application of theoretical knowledge and critical decision-making over simple memorization. Candidates are
,expected to demonstrate proficiency in synthesizing information, performing precise calculations, and
understanding complex biological systems to ensure safe and effective patient care.
SECTION ONE: QUESTIONS 1–100
1. Which of the following heart valves prevents the backflow of blood from the right ventricle into the right
atrium?
A. Mitral valve
B. Aortic valve
🟢 C. Tricuspid valve
D. Pulmonary valve
🔴 RATIONALE: The tricuspid valve is located between the right atrium and the right ventricle. Its primary function
is to prevent blood from flowing backward into the atrium during ventricular contraction.
2. A patient presents with a fever of 38.5°C. What is this temperature in Fahrenheit?
A. 99.8°F
B. 100.4°F
🟢 C. 101.3°F
D. 102.1°F
🔴 RATIONALE: Using the conversion formula (Celsius × 9/5) + 32, (38.5 × 1.8) + 32 equals 101.3°F.
3. Which of the following is the primary site of gas exchange in the respiratory system?
A. Bronchi
B. Trachea
,C. Pharynx
🟢 D. Alveoli
🔴 RATIONALE: Alveoli are the tiny air sacs in the lungs where oxygen and carbon dioxide are exchanged
between the lungs and the bloodstream via the capillaries.
4. In a scientific experiment, which variable is the one that is deliberately changed by the researcher?
🟢 A. Independent variable
B. Dependent variable
C. Controlled variable
D. Qualitative variable
🔴 RATIONALE: The independent variable is the factor manipulated by the scientist to observe its effect on the
dependent variable.
5. Which part of the brain is primarily responsible for regulating balance and equilibrium?
A. Cerebrum
🟢 B. Cerebellum
C. Medulla oblongata
D. Thalamus
🔴 RATIONALE: The cerebellum coordinates voluntary movements such as posture, balance, coordination, and
speech, resulting in smooth and balanced muscular activity.
6. Which organelle is often referred to as the powerhouse of the cell because it generates ATP?
, A. Ribosome
B. Golgi apparatus
🟢 C. Mitochondria
D. Nucleus
🔴 RATIONALE: Mitochondria are responsible for cellular respiration and the production of adenosine
triphosphate (ATP), which provides energy for cellular processes.
7. Which of the following is an example of an intensive property of matter?
🟢 A. Density
B. Mass
C. Volume
D. Length
🔴 RATIONALE: Intensive properties, such as density and boiling point, do not depend on the amount of matter
present, whereas extensive properties like mass and volume do.
8. Which of the following structures 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.
9. What is the process by which a cell engulfs large particles or liquids?
