ATI TEAS 7 Science Pretest Question
and Answer A+ Guide
Inflammation, production of interferon, and ingestion of
pathogens by phagocytes are nonspecific cellular
responses by which of the following?
A.) The internal aspect of adaptive immune system
B.) Antibody-mediated immunity
C.) The internal aspect of the innate immune system
D.) Passive immunity - correct answer ✅✅C.) The
internal aspect of the innate immune system
If the external barrier is breached, the second line of
defense is the internal aspect of the innate immune
system, a collection of nonspecific cellular responses
(inflammation, production of interferon, ingestion of
pathogens by phagocytes).
What feature of the adaptive immune system decreases
the amount of time it takes for the body to respond to a
particular antigen?
,ATI TEAS 7 Science Pretest Question
and Answer A+ Guide
A.) Unbroken skin
B.) Memory Cells
C.) Cytotoxic T-cells
D.) Inflammation - correct answer ✅✅B.) Memory cells
Memory cells are a type of lymphocyte that responds
more quickly to an antigen upon reintroduction of the
pathogen.
Which of the following occurs in the cardiac cycle if the
impulse triggered a at the sinoatrial mode never reaches
the Purkinje fibers of the heart?
A.) The atria will not contract.
B.) There will be an absence of systole.
,ATI TEAS 7 Science Pretest Question
and Answer A+ Guide
C.) The ventricles will not contract.
D.) Diastole will shorten in duration. - correct answer
✅✅C.) The ventricles will not contract.
The Purkinje fiber impulse causes the contraction of the
ventricles.
Which of the following describes the link between
damages villi and malnutrition?
A.) Damaged villi decrease the nutrient-absorbing surface
area in the gastrointestinal tract.
B.) If villi are damaged, the surface area of the stomach is
decreased.
C.)Peristalsis of the large intestine will be diminished.
D.) Damaged villi cause gastric reflux disease. - correct
answer ✅✅A.) Damaged villi decrease the nutrient-
absorbing surface area in the gastrointestinal tract.
, ATI TEAS 7 Science Pretest Question
and Answer A+ Guide
Villi of the small intestine provide a greater nutrient-
absorbing surface area in the gastrointestinal tract.
Which of the following organs is responsible for the
majority of the chemical digestion and absorption of
nutrients in the digestive system?
A.) Large intestine
B.) Small intestine
C.) Liver
D.) Pancreas - correct answer ✅✅B.) Small intestine
The primary function of the small intestine is chemical
digestion and absorption of nutrients.
