1. 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.
2. Which of the following is the most common cause of stroke?
A. Aneurysm rupture
B. Ischemia due to a clot
C. Brain tumor
D. Hypertension
Answer: B) Ischemia due to a clot
Rationale: Ischemic strokes are the most common type of stroke
and occur when a clot blocks blood flow to the brain.
3. 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.
4. What is the main cause of type 2 diabetes?
A. Insulin resistance
,B. Insulin deficiency
C. Autoimmune destruction of beta cells
D. Excessive glucagon secretion
Answer: A) Insulin resistance
Rationale: Type 2 diabetes is primarily caused by insulin
resistance, where the body’s cells do not respond effectively to
insulin, leading to elevated blood glucose levels.
5. A patient has been diagnosed with tuberculosis (TB). Which of
the following is the most common symptom?
A. Night sweats
B. Joint pain
C. Hematuria
D. Abdominal pain
Answer: A) Night sweats
Rationale: Night sweats are a classic symptom of tuberculosis,
along with cough and weight loss.
6. Which of the following lab findings is typically seen in a patient
with acute renal failure (ARF)?
A. Increased serum creatinine
B. Decreased serum potassium
C. Decreased blood urea nitrogen (BUN)
D. Decreased urine output (oliguria)
Answer: A) Increased serum creatinine
Rationale: In acute renal failure, the kidneys' ability to excrete
waste products diminishes, leading to an increase in serum
creatinine levels.
7. What is the most common cause of secondary hypertension?
A. Excessive salt intake
B. Renal disease
C. High cholesterol levels
, D. Alcohol consumption
Answer: B) Renal disease
Rationale: Secondary hypertension is often caused by another
condition, with renal disease being a leading factor due to
impaired kidney function affecting fluid balance and blood
pressure regulation.
8. 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.
9. Which of the following is a primary complication of untreated
hypertension?
A. Diabetes
B. Stroke
C. Asthma
D. Hyperthyroidism
Answer: B) Stroke
Rationale: Untreated hypertension can cause damage to blood
vessels, increasing the risk of a stroke due to the development of
atherosclerosis or rupture of a weakened vessel.
10. A nurse is caring for a patient with pneumonia. Which of the
following is a common sign of pneumonia?
A. Cough with sputum production
B. Sudden weight gain
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.
