NR 283/ NR283 Exam 1: Pathophysiology
(2026/ 2027 Update) | Q/A | Grade A| 100%
Correct - Chamberlain
Subject: Pathophysiology - Homeostasis, Genetics, Cellular Adaptation,
Stress, Cancer
Source: Chamberlain University (NR283 Exam 1 Study Guide)
Format: Multiple-Choice Questions, Definitions, and Pathophysiology
Explanations
Rationale: This document is an exam preparation guide structured as
a series of questions and answers. It covers foundational concepts in
pathophysiology, including homeostasis, genetic disorders (with a focus on
Down syndrome), cellular adaptation, the stress response, and cancer
biology. The format tests recall and application of key definitions and
principles. Providing rationales will clarify the underlying pathophysiology
or logic that makes each selected answer correct, transforming the guide

from a simple answer key into a learning tool that reinforces
understanding.
Multiple Choice & Short Answer Questions with Rationales
1. Homeostasis is defined as...
Answer: "a relatively stable state of equilibrium or a tendency
toward such a state between the different but interdependent
elements of an organism."
Rationale: This is the core definition of homeostasis. It describes the
body's dynamic process of maintaining internal stability (e.g.,
temperature, pH, fluid balance) despite external changes, which is the
fundamental concept upon which pathophysiology is based.
2. Which statement is the most inclusive definition of a risk
factor?
Answer: Something that increases a person's chances of developing a
disease.
Rationale: A risk factor is any attribute, characteristic, or exposure
that increases the likelihood of developing a disease or injury. This
broad definition encompasses genetic, environmental, and behavioral
factors, making it the most inclusive choice.
3. Clinical manifestations are the signals that indicate...
