NURS 209 Nursing Pathophysiology,
NURS 209, Practice HESI Questions with
Answers and Rationales
Introduction:
This document contains extensive NURS 209 practice
questions designed for HESI exam preparation, covering core
pathophysiology concepts across multiple body systems. It
includes fully answered multiple-choice and select-all-that-
apply questions with detailed rationales to support
understanding and exam readiness. The material is suitable for
review throughout the course and for final HESI exam
preparation.
Exam Questions and Answers with Rationales:
The clotting system at the site of injury or inflammation
includes the following function(s): Select all that apply.
A. preventing the spread of infection to adjacent tissues.
B. keeping microorganisms at the site of greatest inflammatory
cell activity.
C. forming constant bleeding to flush out the microorganism.
D. providing a framework for future repair and healing.
,E. disposing of foreign material at the site of a wound. -
Answer:-B. keeping microorganisms at the site of greatest
inflammatory cell activity.
D. providing a framework for future repair and healing.
The clotting system actually forms a clot, which will help stop
bleeding. This allows the microorganism to remain at the site
for destruction. Phagocytosis is the process by which a cell
ingests and disposes of foreign material, including
microorganisms. The other descriptions are all correct and are
important functions of the clotting cascade.
The reconstructive phase of wound healing includes: Select all
that apply.
A. fibroblast proliferation
B. collagen synthesis.
C. neutrophil production.
D. epithelialization.
E. wound contraction. -Answer:-A. fibroblast proliferation
B. collagen synthesis.
D. epithelialization.
E. wound contraction.
,The reconstructive phase begins 3 to 4 days after injury and
continues for up to 2 weeks. During this phase, fibroblasts
proliferate and synthesize collagen. The wound is sealed and
contracts. Neutrophil production is not included in the
reconstructive phase.
It is accurate to state that:
A. allergy means deleterious effects of hypersensitivity.
B. immunity means an altered immunologic response.
C. hypersensitivity means the protective response to an
antigen.
D. autoimmunity is the normal response to foreign antigens. -
Answer:-A. allergy means deleterious effects of
hypersensitivity.
Allergy means the deleterious effects of a hypersensitivity
reaction. The correct definition of immunity is the protective
response to antigens. The correct definition of hypersensitivity
is the altered immunologic response to an antigen.
Autoimmunity is a disturbance in the immunologic tolerance of
self-antigens.
, An accurate description of a type I reaction would be that it:
A. is mediated by IgA.
B. is generally allergic in nature.
C. most often occurs against medications.
D. seldom contributes to autoimmune diseases. -Answer:-B. is
generally allergic in nature.
Most type I reactions are allergic. They are mediated by IgE.
Most occur against environmental antigens and do contribute
to some autoimmune diseases.
Atopic individuals:
A. have a 4% chance that offspring will have allergies, if only
one parent has allergies.
B. have a 50% chance that offspring will have allergies, if both
parents have allergies.
C. tend to produce higher quantities of IgE.
D. have no genes associated with an atopic state. -Answer:-C.
tend to produce higher quantities of IgE.
There are higher quantities of IgE in these individuals. If one
parent has an allergy, the individual has a 40% of having
