1. 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.
2. 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.
3. A patient with a history of gout presents with severe joint pain
in the big toe. What is the most likely cause of this pain?
A. Hyperuricemia
B. Osteoarthritis
C. Rheumatoid arthritis
D. Bone fracture
Answer: A) Hyperuricemia
Rationale: Gout is caused by the accumulation of uric acid crystals
,in the joints, often beginning with the big toe. Elevated uric acid
levels (hyperuricemia) lead to these crystals forming and causing
intense pain.
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 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).
6. 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.
7. 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.
8. 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.
9. 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.
