1. Which of the following is a classic sign of hyperthyroidism?
A. Weight gain
B. Cold intolerance
C. Tachycardia
D. Bradycardia
Answer: C) Tachycardia
Rationale: Hyperthyroidism is characterized by an overproduction
of thyroid hormones, leading to symptoms like tachycardia, heat
intolerance, and weight loss.
2. What is the main cause of liver cirrhosis?
A. Alcohol abuse
B. High-fat diet
C. Viral infections (e.g., hepatitis B or C)
D. Obesity
Answer: A) Alcohol abuse
Rationale: Chronic alcohol use is the leading cause of cirrhosis,
leading to liver fibrosis and eventual liver failure.
3. A nurse is caring for a patient with hyperkalemia. What is the
most concerning sign of this condition?
A. Muscle weakness
B. Shortness of breath
C. Diarrhea
D. Nausea
Answer: A) Muscle weakness
Rationale: Hyperkalemia can cause muscle weakness and
potentially life-threatening arrhythmias due to its effect on the
electrical conductivity of the heart.
4. Which of the following lab results is most likely in a patient
,with dehydration?
A. Low hematocrit
B. Low sodium levels
C. Elevated blood urea nitrogen (BUN)
D. Low creatinine
Answer: C) Elevated blood urea nitrogen (BUN)
Rationale: Dehydration leads to decreased renal perfusion and an
increase in BUN due to reduced fluid volume.
5. What is the primary cause of atherosclerosis?
A. Decreased calcium intake
B. Chronic inflammation of the blood vessels
C. Increased HDL cholesterol
D. Vitamin D deficiency
Answer: B) Chronic inflammation of the blood vessels
Rationale: Atherosclerosis is primarily caused by the build-up of
plaque in the arteries, often triggered by chronic inflammation
and high levels of LDL cholesterol in the bloodstream.
6. 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.
7. A patient with acute bacterial meningitis is likely to experience
which of the following?
A. Increased thirst and urination
B. Severe headache and neck stiffness
, C. Joint pain and swelling
D. Abdominal pain and bloating
Answer: B) Severe headache and neck stiffness
Rationale: Acute bacterial meningitis causes inflammation of the
meninges, leading to symptoms like severe headache, neck
stiffness, photophobia, and fever.
8. 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.
9. Which of the following would you expect in a patient with
Addison’s disease?
A. Increased blood pressure
B. Hyperkalemia
C. Weight gain
D. Increased appetite
Answer: B) Hyperkalemia
Rationale: Addison’s disease, a disorder of the adrenal glands,
leads to decreased cortisol and aldosterone production. This
results in fluid and sodium loss and potassium retention, causing
hyperkalemia.
10. A patient is being treated for acute pancreatitis. What is a
common complication of this condition?
A. Renal failure
A. Weight gain
B. Cold intolerance
C. Tachycardia
D. Bradycardia
Answer: C) Tachycardia
Rationale: Hyperthyroidism is characterized by an overproduction
of thyroid hormones, leading to symptoms like tachycardia, heat
intolerance, and weight loss.
