WGU D236 Objective Assessment
Pathophysiology Exam (Updated for 2025/2026)
– 150 Verified Questions and Answers for an A
Grade
1. Which of the following conditions is characterized by a decrease in the force
of the heart's contraction due to a loss of myocardial contractility: Cardiomyopathy
Rationale: Cardiomyopathy refers to diseases of the heart muscle where the myocardium
becomes weakened and cannot pump blood effectively, leading to a decrease in the force
of contraction.
2. is the term used to describe an excess accumulation of fluid in the interstitial
spaces or body cavities.: Edema
Rationale: Edema is the medical term for swelling caused by excess fluid trapped in the
body's tissues, which can occur due to various pathophysiological processes.
3. Hyperplasia is the increase in the size of an organ or tissue due to the increased
cell size.: False
Rationale: Hyperplasia is an increase in the number of cells, which leads to an increase in
tissue mass. Hypertrophy is the correct term for the increase in cell size.
4. The pathophysiological process that leads to increased blood pressure due to
the constriction of blood vessels is known as:: Hypertension
Rationale: Hypertension is a condition where the blood vessels have persistently raised
pressure, often due to vasoconstriction, increased vascular resistance, or higher blood
volume.
5. The presence of __________ in the urine is an indication of renal pathology
and can be a sign of glomerular injury.: Proteinuria
Rationale: Proteinuria, the presence of an abnormal amount of protein in the urine, often
indicates kidney damage, particularly damage to the glomeruli, which filter waste from
the blood.
6. In a patient with acidosis, the blood pH is abnormally high.: Acidosis is a
condition in which there is too much acid in the body fluids, resulting in a lower-than-
normal blood pH.
7. A patient with a reduced number of red blood cells is likely to be diagnosed
wit: Anemia
Rationale: Anemia is a condition characterized by a deficiency in the number or quality
of red blood cells, which impairs oxygen delivery to the body's tissues.
8. is the term used to describe a high concentration of glucose in the blood:
Hyperglycemia
Rationale: Hyperglycemia refers to high blood sugar levels, which can occur in
conditions such as diabetes when the body cannot use glucose properly.
1/8
, 9. Dyspnea is the medical term for difficulty or labored breathing.: True Rationale:
Dyspnea is indeed the term used to describe the sensation of breathlessness or inadequate
breathing.
10. The accumulation of substances within an artery wall that leads to the
narrowing and potential blockage of blood flow is known as:: Atherosclerosis
Rationale: Atherosclerosis is the buildup of fats, cholesterol, and other substances in and
on the artery walls, which can restrict blood flow.
11. The abnormal enlargement of the left ventricle due to increased workload is
known as: Left ventricular hypertrophy
Rationale: Left ventricular hypertrophy is the thickening of the heart's left ventricle
muscle, often a response to increased blood pressure or heart valve stenosis.
12. Osteoporosis is a condition characterized by an increase in bone density and
strength.: False
Rationale: Osteoporosis is actually a disease where decreased bone strength increases the
risk of a broken bone.
13. Which hormone is primarily involved in the regulation of the metabolic rate
and is often measured in cases of suspected thyroid dysfunction: Thyroxine (T4)
Rationale: Thyroxine, also known as T4, is the main hormone secreted into the
bloodstream by the thyroid gland and is crucial for maintaining metabolism.
14. is a life-threatening condition where the body's response to infection causes
injury to its own tissues and organs.: Sepsis
Rationale: Sepsis is a serious complication of an infection, which can lead to systemic
inflammation and organ failure.
15. Which of the following is NOT a characteristic of chronic inflammation?:
Presence of neutrophils
Rationale: Chronic inflammation is characterized by the presence of macrophages,
lymphocytes, and plasma cells, while neutrophils are typically seen in acute
inflammation.
16. In diabetes mellitus, the lack of insulin leads to __ metabolism of
carbohydrates.: impaired
Rationale: Insulin deficiency in diabetes mellitus results in impaired metabolism of
carbohydrates, leading to hyperglycemia
17. An embolus is a blood clot that travels through the bloodstream and lodges in
a vessel.: True
Rationale: An embolus is a detached intravascular solid, liquid, or gaseous mass that is
carried by the bloodstream and can obstruct blood flow when it becomes lodged in a
vessel.
18. Which of the following is a risk factor for developing chronic kidney disease?:
Hypertension
