Select the single best answer for each question.
Each question has one correct answer and three plausible distractors.
Questions cover endocrine, cardiovascular, respiratory, renal, and hematologic pathophysiology .
Detailed rationales are provided for each question.
Assume standard adult physiology unless otherwise specified.
SECTION I: ENDOCRINE PATHOPHYSIOLOGY (Questions 1–15)
Q1. A patient with type 1 diabetes mellitus is at risk for diabetic ketoacidosis (DKA). The primary
pathophysiologic mechanism of DKA is:
A) Absolute insulin deficiency leading to increased lipolysis and ketone production
B) Insulin resistance leading to hyperglycemia
C) Decreased glucose absorption from the gastrointestinal tract
D) Increased glucagon secretion leading to hypoglycemia
Answer: A
Rationale: In type 1 diabetes, absolute insulin deficiency leads to increased lipolysis (breakdown of fat), which
produces free fatty acids that are converted to ketone bodies in the liver. This results in metabolic acidosis
(DKA). Insulin resistance (B) is the primary mechanism of type 2 diabetes.

Q2. A patient with type 2 diabetes mellitus has insulin resistance. Which of the following is a characteristic
finding in type 2 diabetes?
A) Hyperinsulinemia (elevated insulin levels)
B) Absolute insulin deficiency
C) Presence of islet cell antibodies
D) Ketoacidosis at diagnosis
Answer: A
Rationale: Type 2 diabetes is characterized by insulin resistance, and the pancreas initially compensates by
producing more insulin (hyperinsulinemia). Absolute insulin deficiency (B) is seen in type 1 diabetes. Islet cell
antibodies (C) are present in type 1 diabetes. Ketoacidosis (D) is rare at diagnosis of type 2 diabetes.

Q3. A patient with hyperthyroidism (Graves' disease) presents with weight loss, heat intolerance, and
tachycardia. The pathophysiology of hyperthyroidism in Graves' disease involves:
A) Autoantibodies (TSI) that stimulate the TSH receptor
B) Autoimmune destruction of the thyroid gland
C) Pituitary adenoma secreting excess TSH
D) Iodine deficiency

EXAM 2 TEST BANK LATEST 2026/2027 | MOST TESTED | 75 VERIFIED Q&A | NGN-
STYLE | CHAMBERLAIN | PASS GUARANTEED - A+ GRADED
Answer: A
Rationale: Graves' disease is caused by autoantibodies called thyroid-stimulating immunoglobulins (TSI) that
bind to and activate the TSH receptor, leading to unregulated thyroid hormone production and
hyperthyroidism.

Q4. A patient with hypothyroidism presents with fatigue, weight gain, and cold intolerance. The most
common cause of hypothyroidism worldwide is:
A) Iodine deficiency
B) Hashimoto's thyroiditis
C) Pituitary tumor
D) Thyroidectomy
Answer: A
Rationale: Worldwide, iodine deficiency is the most common cause of hypothyroidism. In iodine-sufficient
regions (like the US), Hashimoto's thyroiditis (autoimmune) is the most common cause.

Q5. A patient with Cushing's syndrome (excess cortisol) develops hyperglycemia. The mechanism of
hyperglycemia in Cushing's syndrome is:
A) Cortisol promotes gluconeogenesis and decreases peripheral glucose utilization (insulin resistance)
B) Cortisol increases insulin secretion
C) Cortisol decreases glucagon secretion
D) Cortisol increases glucose excretion in urine
Answer: A
Rationale: Cortisol is a counter-regulatory hormone that increases blood glucose by promoting
gluconeogenesis (liver) and inducing peripheral insulin resistance (decreased glucose uptake by muscle and
fat). This can lead to steroid-induced hyperglycemia or diabetes.

Q6. A patient with diabetes insipidus presents with polyuria and polydipsia. The pathophysiology of central
diabetes insipidus involves:
A) Decreased ADH production by the hypothalamus/posterior pituitary
B) Decreased renal response to ADH (nephrogenic)
C) Increased ADH production
D) Increased aldosterone production
