Assessment, Diagnosis, and Management for acute and chronic conditions in primary
care.
DOMAINS COVERED:
1. Cardiovascular System
2. Respiratory System
3. Gastrointestinal System
4. Endocrine System

8. Dermatology
9. Professional Practice & Health Promotion
Question 1
Which acid-base disturbance is most consistent with prolonged vomiting?
A. Metabolic acidosis
B. Respiratory acidosis
C. Metabolic alkalosis
,D. Respiratory alkalosis
Correct Answer: C
Rationale: Vomiting results in loss of gastric hydrochloric acid, leading to increased
bicarbonate levels and metabolic alkalosis.
Question 2
A patient with type 2 diabetes presents with polyuria and polydipsia. Which
mechanism primarily causes these symptoms?
A. Insulin resistance at peripheral receptors
B. Increased hepatic gluconeogenesis
C. Osmotic diuresis from hyperglycemia
D. Reduced antidiuretic hormone secretion
Correct Answer: C
Rationale: Elevated blood glucose exceeds renal reabsorption capacity, causing
glucose to spill into urine and pull water with it, resulting in osmotic diuresis.
Question 3
Which finding is most characteristic of systolic heart failure?
A. Preserved ejection fraction
,B. Ventricular wall thickening
C. Reduced cardiac contractility
D. Increased ventricular compliance
Correct Answer: C
Rationale: Systolic heart failure is defined by impaired myocardial contractility and
reduced ejection fraction.
Question 4
A patient with chronic kidney disease develops secondary hyperparathyroidism.
What is the primary cause?
A. Increased calcium absorption
B. Excess vitamin D activation
C. Phosphate retention and hypocalcemia
D. Elevated calcitonin secretion
Correct Answer: C
Rationale: Impaired phosphate excretion leads to hyperphosphatemia, which lowers
serum calcium and stimulates parathyroid hormone release.
Question 5
Which immune response is primarily responsible for allergic reactions?
, A. Type I hypersensitivity
B. Type II hypersensitivity
C. Type III hypersensitivity
D. Type IV hypersensitivity
Correct Answer: A
Rationale: Type I hypersensitivity is IgE-mediated and responsible for immediate
allergic reactions such as anaphylaxis and urticaria.
Question 6
A patient develops jaundice due to obstruction of the common bile duct. Which
laboratory pattern is expected?
A. Elevated unconjugated bilirubin
B. Elevated conjugated bilirubin
C. Decreased alkaline phosphatase
D. Decreased gamma-glutamyl transferase
Correct Answer: B
Rationale: Obstructive jaundice prevents excretion of conjugated bilirubin, leading
to elevated serum levels.
