Questions 1 – 97
CHEMISTRY — EXAM 1
1. Anatomy is defined as:
A. The study of body function
B. The study of body structure
C. The study of chemical reactions
D. The study of disease processes
CORRECT ANSWER B — The study of body structure
RATIONALE Anatomy (from Greek "anatome" meaning dissection) is the scientific study of the
structure of organisms and their parts. It describes the physical arrangement,
location, and relationships of body parts. Physiology (A) is the study of body
function. Chemistry (C) is the study of matter and reactions. Pathology (D) is the
study of disease. Anatomy and physiology are complementary — structure
determines function.
2. Physiology is defined as:
A. The study of body structure
B. The study of body function
C. The study of microscopic organisms
D. The study of cellular chemistry only
CORRECT ANSWER B — The study of body function
RATIONALE Physiology is the scientific study of the functions and mechanisms of living
organisms — how body parts work and carry out their life-sustaining activities. It
explains the chemical and physical processes underlying body function. Anatomy
(A) studies structure. Microbiology (C) studies microorganisms. Cellular chemistry
(D) is one component of physiology but not the complete definition. The principle
of complementarity states that anatomy (structure) and physiology (function) are
inseparable.
,3. The correct order of structural organization from simplest to most complex is:
A. Organism, organ system, organ, tissue, cell, molecule, atom
B. Atom, molecule, cell, tissue, organ, organ system, organism
C. Cell, tissue, atom, molecule, organ, organ system, organism
D. Tissue, cell, organ, atom, molecule, organ system, organism
CORRECT ANSWER B — Atom → Molecule → Cell → Tissue → Organ → Organ System →
Organism
RATIONALE The levels of structural organization proceed from simplest to most complex:
atoms (chemical level) combine to form molecules (macromolecules), which
organize into cells (the basic unit of life). Similar cells form tissues, tissues form
organs, organs work together in organ systems, and all systems constitute the
organism. This hierarchy reflects increasing complexity and emergent properties
at each level. Option A reverses the order.
4. Homeostasis is best defined as:
A. The process of cell division
B. The process by which organisms maintain a relatively stable internal environment
C. The breakdown of glucose for energy
D. The synthesis of proteins from amino acids
CORRECT ANSWER B — Maintaining a relatively stable internal environment
RATIONALE Homeostasis (from Greek "homeo" = same, "stasis" = standing still) is the dynamic
equilibrium maintained by the body through continuous monitoring and
adjustment of physiological variables. It involves receptor → control center →
effector feedback loops. Examples include temperature regulation, blood glucose
control, and pH balance. Option A is mitosis. Option C is glycolysis/catabolism.
Option D is translation. Homeostasis is a central organizing principle of
physiology.
, 5. The standard anatomical position is described as:
A. Lying face down with arms at sides
B. Standing erect with arms at sides and palms facing forward
C. Sitting with arms crossed
D. Standing with palms facing backward
CORRECT ANSWER B — Standing erect, arms at sides, palms facing forward
RATIONALE The anatomical position is the standardized reference point for anatomical
descriptions: body erect, feet slightly apart, arms at sides, palms facing forward
(supinated), thumbs pointing away from the body. This position ensures
consistent directional terminology regardless of the patient's actual position.
Option A describes the prone position. The anatomical position is essential for
accurate communication in healthcare.
6. A patient lying face up is in the _____ position; a patient lying face down is in the _____
position.
A. Prone; supine
B. Supine; prone
C. Lateral; dorsal
D. Ventral; dorsal
CORRECT ANSWER B — Supine (face up); Prone (face down)
RATIONALE Supine position: lying on the back, face upward. Prone position: lying on the
stomach, face downward. These terms are commonly used in surgery, physical
examination, and nursing care. Option A reverses the definitions. Lateral refers to
the side. Dorsal refers to the back. Correct body position terminology is essential
for accurate clinical communication and documentation.
