): Advanced Pathophysiology
| Questions and Verified Answers |
Graded A - Maryville
EXAM 3 TOPIC OVERVIEW
NURS 611 Exam 3 typically covers advanced pathophysiology concepts including:
• Endocrine Disorders (Diabetes, Thyroid, Adrenal, Pituitary)
• Cardiovascular Pathophysiology (Hypertension, Heart Failure, Aneurysms)
• Renal & Urinary Disorders (AKI, CKD, Glomerular Disorders)
• Hematologic & Immunologic Alterations
• Neurologic & Musculoskeletal Conditions
• Multisystem Dysfunction & Fluid/Electrolyte Imbalances
SECTION 1: ENDOCRINE PATHOPHYSIOLOGY (Questions 1-30)
1. Type 1 diabetes mellitus is the result of:
• A) Insulin resistance at the cellular level
• B) Autoimmune destruction of pancreatic beta cells
• C) Impaired glucose uptake by adipose tissue
• D) Excessive glucagon secretion
,Answer: B – Autoimmune destruction of pancreatic beta cells
Rationale: Type 1 diabetes is an autoimmune disorder in which cytotoxic T
lymphocytes destroy pancreatic beta cells, leading to absolute insulin deficiency.
Type 2 diabetes, in contrast, involves insulin resistance. Type 1A diabetes
specifically involves autoimmune-mediated beta cell destruction.
2. The basic pathophysiology of type 2 diabetes mellitus involves:
• A) Loss of pancreatic beta cells
• B) Development of insulin-resistant tissue cells
• C) Autoimmune destruction of islet cells
• D) Viral infection of the pancreas
Answer: B – Development of insulin-resistant tissue cells
Rationale: Type 2 DM is characterized by insulin resistance at the cellular level.
Target tissues (muscle, liver, adipose) become less responsive to insulin, leading to
hyperglycemia. Unlike type 1, beta cell destruction is not the primary mechanism.
3. A patient with type 1 diabetes who experiences low blood glucose during the
night followed by morning rebound hyperglycemia is demonstrating:
• A) Dawn phenomenon
• B) Somogyi effect
• C) Hyperosmolar hyperglycemic state
• D) Diabetic ketoacidosis
,Answer: B – Somogyi effect
Rationale: The Somogyi effect describes a cycle of hypoglycemia during the night
that triggers a counterregulatory hormone response, leading to rebound
hyperglycemia in the morning. This is distinct from the dawn phenomenon, which
involves early morning hyperglycemia without preceding hypoglycemia.
4. The dawn phenomenon in a patient with type 1 diabetes is characterized by:
• A) Low blood glucose in the early morning compared to the middle of the
night
• B) Higher blood glucose in the early morning compared to the middle of the
night
• C) Equal blood glucose throughout the night
• D) Hypoglycemia followed by hyperglycemia
Answer: B – Higher blood glucose in the early morning compared to the middle
of the night
Rationale: The dawn phenomenon results from the normal early morning surge in
growth hormone and cortisol, which increases blood glucose levels. Unlike the
Somogyi effect, it is not preceded by hypoglycemia.
5. Women who have gestational diabetes have a(n) _____ risk for developing
type 2 diabetes later in life:
• A) Decreased
• B) Unchanged
, • C) Increased
• D) Eliminated
Answer: C – Increased
Rationale: Women with gestational diabetes have a significantly increased risk of
developing type 2 diabetes later in life due to underlying insulin resistance that may
persist or worsen.
6. Metabolic syndrome increases the risk of developing which type of
diabetes?
• A) Type 1
• B) Type 1A
• C) Type 2
• D) Gestational
Answer: C – Type 2
Rationale: Metabolic syndrome, characterized by abdominal obesity, insulin
resistance, hypertension, and dyslipidemia, significantly increases the risk of
developing type 2 diabetes.
7. The hormone secreted by intestinal endocrine cells that enhances insulin
secretion is called:
• A) Glucagon
• B) Somatostatin
