,ATI Anatomy & Physiology Assessment Exam Questions And Answers
2026/2027
1.** A nurse is teaching a client about cellular adaptation. Which statement
correctly describes the difference between anatomy and physiology?
A) Anatomy is the study of function, and physiology is the study of structure.
B) Anatomy is the study of structure, and physiology is the study of function.
C) Anatomy and physiology are the same discipline.
D) Anatomy studies disease, and physiology studies treatment.
**Correct Answer:** B) Anatomy is the study of structure, and physiology is
the study of function.
**Rationale:** Anatomy is the study of the structure and relationships of
body parts. Physiology is the study of the function of body parts. They are
distinct but complementary disciplines.
**2.** A nurse is reviewing the levels of biological organization. Which of the
following represents the correct sequence from simplest to most complex?
A) Cell, tissue, organ, organ system, organism
B) Tissue, cell, organ, organ system, organism
C) Organ, tissue, cell, organ system, organism
D) Cell, organ, tissue, organ system, organism
**Correct Answer:** A) Cell, tissue, organ, organ system, organism
**Rationale:** The levels of biological organization progress from the
simplest (cells) to the most complex (organism). Cells form tissues, tissues
,form organs, organs form organ systems, and organ systems work together
to form an organism.
**3.** A client asks the nurse about the function of the nucleus in a cell.
Which of the following is the best response?
A) "The nucleus produces energy for the cell."
B) "The nucleus is the control center of the cell and contains DNA."
C) "The nucleus synthesizes proteins."
D) "The nucleus modifies and packages proteins."
**Correct Answer:** B) "The nucleus is the control center of the cell and
contains DNA."
**Rationale:** The nucleus is the control center of the cell, containing the
cell's genetic material (DNA). It regulates gene expression and directs
cellular activities. The mitochondria (A) produce energy (ATP). Ribosomes (C)
synthesize proteins. The Golgi apparatus (D) modifies and packages proteins.
**4.** A nurse is teaching a client about tissue types. Which type of tissue is
responsible for lining body cavities and covering body surfaces?
A) Connective tissue
B) Muscle tissue
C) Nervous tissue
D) Epithelial tissue
**Correct Answer:** D) Epithelial tissue
, **Rationale:** Epithelial tissue covers body surfaces and lines body cavities
and organs. Connective tissue (A) supports and binds structures. Muscle
tissue (B) is responsible for movement. Nervous tissue (C) transmits
electrical impulses.
**5.** A nurse is explaining the process of mitosis to a client. Which of the
following is a result of mitosis?
A) Production of gametes (sperm and egg cells)
B) Production of two identical daughter cells
C) Reduction of chromosome number by half
D) Formation of cells with genetic variation
**Correct Answer:** B) Production of two identical daughter cells
**Rationale:** Mitosis results in two genetically identical daughter cells with
the same number of chromosomes as the parent cell. It is used for growth,
repair, and replacement of somatic cells. Meiosis (A, C, D) produces gametes
with half the chromosome number and genetic variation.
**6.** A nurse is reviewing the function of organelles. Which organelle is
responsible for the synthesis of proteins?
A) Mitochondria
B) Ribosomes
C) Lysosomes
D) Golgi apparatus
**Correct Answer:** B) Ribosomes
