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. 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. 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.
,4. What is the most common cause of peptic ulcers?
A. Stress
B. Use of nonsteroidal anti-inflammatory drugs (NSAIDs)
C. Helicobacter pylori infection
D. Excessive alcohol consumption
Answer: C) Helicobacter pylori infection
Rationale: H. pylori infection is the leading cause of peptic ulcers
due to its ability to disrupt the mucosal lining of the stomach.
5. Which of the following is the primary treatment goal for a
patient with acute myocardial infarction (MI)?
A. Increase fluid intake
B. Reduce heart rate and oxygen demand
C. Prevent deep vein thrombosis
D. Enhance gastrointestinal function
Answer: B) Reduce heart rate and oxygen demand
Rationale: The primary goal in managing MI is to reduce the
heart's workload by decreasing heart rate and oxygen demand to
prevent further damage to the heart muscle.
6. 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.
7. 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.
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. 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.
10. Which of the following is the most common cause of stroke?
A. Aneurysm rupture
B. Ischemia due to a clot
C. Brain tumor
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.
