PORTAGE PATHOPHYSIOLOGY MODULE 9 – FULL
COMPREHENSIVE PRACTICE EXAM
SECTION I: MULTIPLE CHOICE
1. A 58-year-old obese female with a sedentary lifestyle presents with fatigue,
blurred vision, and a fasting blood glucose of 145 mg/dL. Her C-peptide levels
are normal to high. Which pathophysiological mechanism BEST explains her
condition?
• A) Autoimmune destruction of pancreatic beta cells
• B) Insulin resistance at the cellular receptor level
• C) Viral destruction of the islets of Langerhans
• D) Absolute deficiency of glucagon
Answer: B) Insulin resistance at the cellular receptor level
Rationale: This patient has Type 2 Diabetes Mellitus, evidenced by obesity,
sedentary lifestyle, mild hyperglycemia, and normal/high C-peptide (indicating the
pancreas still produces insulin). The primary defect is insulin resistance, where
target cells fail to respond to insulin. Option A and C describe Type 1 DM, and D is
incorrect because glucagon is usually elevated in diabetes.
2. Which of the following hormones is synthesized in the hypothalamus and
stored in the posterior pituitary?
• A) Growth Hormone (GH)
, • B) Thyroid-Stimulating Hormone (TSH)
• C) Antidiuretic Hormone (ADH)
• D) Adrenocorticotropic Hormone (ACTH)
Answer: C) Antidiuretic Hormone (ADH)
Rationale: ADH and Oxytocin are synthesized in the hypothalamic nuclei
(supraoptic and paraventricular) and transported down the pituitary stalk for
storage in the posterior pituitary. GH, TSH, and ACTH are all synthesized in the
ANTERIOR pituitary.
3. A patient with Cushing's syndrome is at risk for which of the following
complications?
• A) Hypoglycemia and hypotension
• B) Osteoporosis and immunosuppression
• C) Weight loss and muscle hypertrophy
• D) Bradycardia and hypothermia
Answer: B) Osteoporosis and immunosuppression
Rationale: Chronic excess cortisol (Cushing's) leads to protein catabolism (muscle
wasting, osteoporosis by decreasing bone formation), immunosuppression
(increased infection risk), hyperglycemia, hypertension, and central obesity.
Options A, C, and D describe opposite or unrelated effects.
4. A 24-year-old male with Type 1 DM is found unresponsive. His breath has a
fruity odor. ABG shows pH 7.20 and HCO3- 12 mEq/L. Which of the following is
the PRIORITY intervention?
• A) Oral glucose tablets
• B) IV regular insulin and normal saline
, • C) IV sodium bicarbonate push
• D) Subcutaneous glucagon
Answer: B) IV regular insulin and normal saline
Rationale: This is Diabetic Ketoacidosis (DKA) – low pH, low bicarb, fruity breath
(acetone). The priority is to correct dehydration with IV fluids (NS) and stop
ketogenesis with IV insulin. Bicarbonate is rarely given unless pH is <6.9. Glucagon
is for hypoglycemia, not DKA.
5. Which of the following is a microvascular complication of Diabetes Mellitus?
• A) Atherosclerosis
• B) Peripheral vascular disease
• C) Diabetic retinopathy
• D) Cerebrovascular accident
Answer: C) Diabetic retinopathy
Rationale: Microvascular complications affect small blood vessels and include
retinopathy, nephropathy, and neuropathy. Macrovascular complications (A, B, D)
affect large vessels and include CAD, PVD, and CVA.
6. A patient with Addison's disease is experiencing severe vomiting,
hypotension, and hyponatremia. Which hormonal deficiency is PRIMARILY
responsible for the hyponatremia?
• A) Cortisol deficiency
• B) Aldosterone deficiency
• C) ADH excess
• D) Glucagon deficiency
