Chamberlain University, 2026 – Complete Proctored Exam
Questions and Correct Answers
Introduction
This document contains a comprehensive collection of proctored
midterm exam questions with correct answers for NR-507
Advanced Pathophysiology at Chamberlain University. It covers
cellular injury, inflammation, immune and hypersensitivity
disorders, hematologic conditions, cardiovascular, respiratory,
renal, endocrine, urinary, and oncologic pathophysiology, along
with clinical reasoning and nursing-focused exam questions. The
material is presented in a question-and-answer format, making it
an excellent study resource for reviewing essential pathophysiology
concepts, reinforcing clinical knowledge, and preparing for the NR-
507 Week 4 midterm examination.
Exam Questions and Answers
1: What is the primary function of the kidney in maintaining
homeostasis?--- correct precise answer ---
,Page 2 of 99
The primary function of the kidney in maintaining homeostasis is
to filter blood, remove waste products, and regulate fluid and
electrolyte balance.
2: How does the renin-angiotensin-aldosterone system (RAAS)
regulate blood pressure?--- correct precise answer ---
The RAAS regulates blood pressure by increasing blood volume and
constricting blood vessels. Renin converts angiotensinogen to
angiotensin I, which is then converted to angiotensin II, leading to
vasoconstriction and aldosterone release, increasing sodium and
water reabsorption.
3: What role do antidiuretic hormone (ADH) play in fluid balance?--
- correct precise answer ---
ADH, also known as vasopressin, helps maintain fluid balance by
promoting water reabsorption in the kidneys, reducing urine
output, and increasing blood volume.
4: Describe the pathophysiology of diabetes mellitus type 2.
Diabetes mellitus type 2 is characterized by insulin resistance and
relative insulin deficiency. The body?--- correct precise answer ---s
cells become less responsive to insulin, leading to elevated blood
glucose levels, and the pancreas may not produce enough insulin to
maintain normal glucose levels.
5: What are the common symptoms of hyperthyroidism?--- correct
precise answer ---
,Page 3 of 99
Common symptoms of hyperthyroidism include weight loss,
increased appetite, nervousness, tremors, heat intolerance,
sweating, and palpitations.
6: How does hypothyroidism affect metabolism?--- correct precise
answer ---
Hypothyroidism slows down metabolism due to insufficient
production of thyroid hormones, leading to symptoms such as
fatigue, weight gain, cold intolerance, and depression.
7: What is the significance of the T3 and T4 hormones in the body?-
-- correct precise answer ---
T3 (triiodothyronine) and T4 (thyroxine) are thyroid hormones that
regulate metabolism, energy production, and overall growth and
development in the body.
8: Explain the role of the parathyroid hormone (PTH) in calcium
regulation. PTH regulates calcium levels in the blood by increasing
calcium reabsorption in the kidneys, releasing calcium from bones,
and enhancing absorption of calcium in the intestines.
9: What are the primary causes of Cushings syndrome?--- correct
precise answer ---
Cushings syndrome is primarily caused by prolonged exposure to
high levels of cortisol, either due to endogenous overproduction
(e.g., pituitary adenoma) or exogenous sources (e.g., corticosteroid
medication).

10: How does Addisons disease affect the adrenal glands?--- correct
precise answer ---
Addisons disease affects the adrenal glands by causing insufficient
production of cortisol and aldosterone, leading to symptoms like
fatigue, weight loss, low blood pressure, and hyperpigmentation.
11: What is the role of insulin in glucose metabolism?--- correct
precise answer ---
Insulin facilitates the uptake of glucose by cells for energy
production, promotes glycogen synthesis in the liver, and regulates
blood glucose levels by reducing hyperglycemia.
12: Describe the pathophysiological changes in chronic obstructive
pulmonary disease (COPD).
COPD is characterized by chronic inflammation, narrowing of the
airways, and destruction of lung tissue, leading to airflow
obstruction, difficulty breathing, and impaired gas exchange.
13: What are the main differences between type 1 and type 2
diabetes?--- correct precise answer --- Type 1 diabetes is an
autoimmune condition where the pancreas produces little or no
insulin, whereas type 2 diabetes involves insulin resistance and
relative insulin deficiency.
14: Explain the concept of insulin resistance.
Insulin resistance occurs when cells in the body become less
responsive to insulin, leading to impaired glucose uptake and
increased blood sugar levels.
