Time Allowed: 60 Minutes
Total Questions: 44 (This booklet contains Questions 1–30)
Instructions to Candidates:
Read each question carefully and select the one best answer. All questions are
multiple-choice with four possible answers. Only one answer is correct. You
are advised to manage your time efficiently, allowing approximately 1–1.5
minutes per question. No external materials are permitted. Answers should be
based on your understanding of anatomy, physiology, and life sciences
concepts relevant to nursing practice.
Disclaimer:
This is an original simulation designed for educational purposes. It is inspired
by the structure and content domains of the ATI TEAS 7 examination but does
not contain actual exam questions.
Core Domains Assessed:
• Human Anatomy and Physiology
• Cellular Biology and Genetics
• Body Systems Integration
• Homeostasis and Regulation
, • Microbiology and Infection Control
This assessment evaluates foundational scientific knowledge essential for
nursing education, focusing on human body systems, cellular processes, and
biological principles. Candidates are expected to apply critical thinking to
physiological mechanisms and disease processes. Mastery of these topics
supports safe and effective patient care in clinical settings.
Q1. A patient presents with muscle weakness and fatigue. Laboratory results
indicate decreased calcium levels. Which physiological process is most directly
affected by this imbalance?
A. Oxygen transport in erythrocytes
B. Neuromuscular transmission
C. Hormone secretion by endocrine glands
D. Renal filtration rate
Correct Answer: B. Neuromuscular transmission
Explanation: Calcium ions are essential for neurotransmitter release at
synapses and muscle contraction. Low calcium disrupts neuromuscular
signaling, leading to weakness. A is incorrect because oxygen transport
depends on hemoglobin. C is unrelated as hormone secretion is not directly
dependent on calcium in this context. D involves kidney function, not
neuromuscular activity.
Q2. Which structure is primarily responsible for filtering blood in the kidney?
A. Loop of Henle
B. Glomerulus
C. Renal pelvis
D. Collecting duct
Correct Answer: B. Glomerulus
Explanation: The glomerulus filters blood plasma into the nephron. A
concentrates urine, C collects urine, and D transports urine—not filtration.
Q3. A mutation affects the ribosomes within a cell. Which process will be
directly impaired?
,A. DNA replication
B. Protein synthesis
C. Lipid metabolism
D. ATP production
Correct Answer: B. Protein synthesis
Explanation: Ribosomes are responsible for translating mRNA into proteins.
A occurs in the nucleus, C in smooth ER, and D in mitochondria.
Q4. Which hormone is responsible for lowering blood glucose levels?
A. Glucagon
B. Insulin
C. Cortisol
D. Epinephrine
Correct Answer: B. Insulin
Explanation: Insulin promotes glucose uptake into cells. A increases
glucose, C and D raise glucose during stress.
Q5. A patient experiences damage to the alveoli. Which function is primarily
compromised?
A. Blood filtration
B. Gas exchange
C. Nutrient absorption
D. Hormone secretion
Correct Answer: B. Gas exchange
Explanation: Alveoli allow oxygen and carbon dioxide exchange. Other
options are unrelated to lung structure.
Q6. Which organelle is responsible for detoxification and lipid synthesis?
A. Rough ER
B. Smooth ER
C. Golgi apparatus
D. Lysosome
, Correct Answer: B. Smooth ER
Explanation: Smooth ER synthesizes lipids and detoxifies substances. Rough
ER handles proteins, Golgi modifies proteins, lysosomes digest waste.
Q7. During exercise, which system increases oxygen delivery to tissues?
A. Digestive system
B. Cardiovascular system
C. Endocrine system
D. Lymphatic system
Correct Answer: B. Cardiovascular system
Explanation: It transports oxygen via blood. Other systems are not primarily
responsible for oxygen delivery.
Q8. Which type of tissue lines internal organs and cavities?
A. Connective tissue
B. Muscle tissue
C. Nervous tissue
D. Epithelial tissue
Correct Answer: D. Epithelial tissue
Explanation: Epithelial tissue forms protective linings. Others have
structural, movement, or signaling roles.
Q9. What is the main function of hemoglobin?
A. Fight infection
B. Carry oxygen
C. Regulate pH
D. Clot blood
Correct Answer: B. Carry oxygen
Explanation: Hemoglobin binds oxygen in red blood cells. A is leukocytes, D
is platelets.
