1. 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.
2. Which of the following is a common cause of hypoxemia?
A. Anemia
B. Asthma
C. Hypertension
D. Diabetes
Answer: B) Asthma
Rationale: Asthma causes bronchoconstriction and inflammation
in the airways, leading to decreased oxygen exchange and
resulting in hypoxemia.
3. A patient with acute blood loss from a traumatic injury may
experience which of the following?
A. Decreased heart rate
B. Decreased respiratory rate
C. Increased blood pressure
D. Increased heart rate
Answer: D) Increased heart rate
Rationale: Acute blood loss leads to a decrease in circulating
blood volume, which triggers compensatory tachycardia
(increased heart rate) to maintain cardiac output.
,4. What is the primary cause of osteoarthritis?
A. Autoimmune reaction
B. Wear and tear on the joints
C. Bacterial infection
D. Vitamin D deficiency
Answer: B) Wear and tear on the joints
Rationale: Osteoarthritis is primarily caused by the degeneration
of cartilage due to repetitive use or aging, leading to joint pain
and stiffness.
5. What condition is characterized by the failure of the heart to
pump effectively, leading to inadequate tissue perfusion?
A. Stroke
B. Coronary artery disease (CAD)
C. Heart failure
D. Hypertension
Answer: C) Heart failure
Rationale: Heart failure occurs when the heart is unable to pump
blood efficiently, leading to reduced perfusion of tissues and
organs.
6. What is a common complication of untreated hyperthyroidism?
A. Heart failure
B. Bradycardia
C. Hypoglycemia
D. Myxedema coma
Answer: A) Heart failure
Rationale: Untreated hyperthyroidism can lead to tachycardia and
increased cardiac workload, which can eventually result in heart
failure.
7. 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.
8. A patient diagnosed with a brain tumor presents with sudden
weakness on one side of the body. What could this symptom
indicate?
A. Stroke
B. Seizure
C. Hemiparesis
D. Epilepsy
Answer: C) Hemiparesis
Rationale: Hemiparesis refers to weakness or partial paralysis on
one side of the body, which can occur with a brain tumor that
affects the motor areas of the brain.
9. A patient presents with fever, jaundice, and dark urine. Which
condition might this indicate?
A. Hepatitis
B. Gallstones
C. Pancreatitis
D. Cirrhosis
Answer: A) Hepatitis
Rationale: Hepatitis can lead to liver inflammation, resulting in
jaundice (yellowing of the skin), dark urine, and fever.
10. A nurse is caring for a patient with pneumonia. Which of the
following is a common sign of pneumonia?
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.
