1. A patient with diabetes mellitus presents with polyuria,
polydipsia, and weight loss. What condition might these
symptoms indicate?
A. Diabetic ketoacidosis (DKA)
B. Hyperosmolar hyperglycemic state (HHS)
C. Hypoglycemia
D. Hypertension
Answer: A) Diabetic ketoacidosis (DKA)
Rationale: DKA occurs when insulin deficiency causes increased
glucose production and fat breakdown, leading to ketosis and
elevated blood glucose levels, which cause symptoms like
polyuria, polydipsia, and weight loss.
2. Which of the following would most likely cause a decrease in
blood pressure?
A. Activation of the sympathetic nervous system
B. Release of aldosterone
C. Release of antidiuretic hormone (ADH)
D. Decreased blood volume
Answer: D) Decreased blood volume
Rationale: Decreased blood volume reduces venous return, leading
to reduced cardiac output and a drop in blood pressure.
3. Which of the following is a common sign of hypovolemic
shock?
A. Bradycardia
B. Tachycardia
C. Warm skin
D. Hypertension
Answer: B) Tachycardia
Rationale: In hypovolemic shock, blood volume decreases, and the
,body compensates by increasing the heart rate (tachycardia) to
maintain blood flow to vital organs.
4. Which of the following is the most likely cause of anaphylactic
shock?
A. Blood loss
B. Allergic reaction
C. Bacterial infection
D. Spinal cord injury
Answer: B) Allergic reaction
Rationale: Anaphylactic shock is a severe allergic reaction that
causes vasodilation and fluid leakage, leading to hypotension and
shock.
5. A patient is being treated for acute pancreatitis. What is a
common complication of this condition?
A. Renal failure
B. Chronic diarrhea
C. Hyperglycemia
D. Gallstones
Answer: A) Renal failure
Rationale: Acute pancreatitis can lead to systemic complications,
including renal failure, due to inflammation and the release of
digestive enzymes into the bloodstream.
6. What is the most common cause of secondary osteoporosis?
A. Calcium deficiency
B. Hyperparathyroidism
C. Long-term use of corticosteroids
D. Vitamin D deficiency
Answer: C) Long-term use of corticosteroids
Rationale: Long-term corticosteroid use is a major cause of
secondary osteoporosis due to its effect on bone metabolism,
, leading to decreased bone density and increased fracture risk.
7. In which of the following conditions would you expect an
increase in erythrocyte sedimentation rate (ESR)?
A. Acute inflammation
B. Dehydration
C. Iron deficiency anemia
D. Chronic hypertension
Answer: A) Acute inflammation
Rationale: ESR is an indicator of inflammation. It increases during
acute inflammatory processes, such as infections, autoimmune
diseases, and other inflammatory conditions.
8. What is the primary cause of hypercapnia in patients with
chronic obstructive pulmonary disease (COPD)?
A. Increased carbon dioxide production
B. Airway obstruction
C. Pulmonary fibrosis
D. Decreased tidal volume
Answer: B) Airway obstruction
Rationale: In COPD, airway obstruction leads to difficulty in
exhaling CO2, resulting in the accumulation of carbon dioxide in
the bloodstream (hypercapnia).
9. Which of the following is a typical sign of hypoglycemia?
A. Increased thirst
B. Shaking and sweating
C. Increased urination
D. Elevated blood pressure
Answer: B) Shaking and sweating
Rationale: Hypoglycemia causes symptoms such as shaking,
sweating, and confusion due to the body's response to low blood
sugar levels.
