Section 1: Complex Physiology and Diagnostic Reasoning
Question 1
A patient with chronic liver failure presents with ascites, jaundice, and confusion. The nurse
understands that the confusion is most likely a result of which pathophysiological process?
A) Hyperglycemia causing osmotic shifts in the brain
,B) The liver's inability to convert ammonia to urea, leading to hepatic encephalopathy
C) Increased production of acetylcholine in the central nervous system
D) A sudden increase in cerebral perfusion pressure
CorreCt Answer: B
Rationale: The failing liver cannot metabolize ammonia (a byproduct of protein
breakdown) into urea. The resulting hyperammonemia crosses the blood-brain barrier, leading
to neurotoxicity and the symptoms of hepatic encephalopathy.
Question 2
A patient's arterial blood gas reveals: pH 7.22, PaCO2 60 mmHg, and HCO3 36 mEq/L. How
should the nurse interpret this result?
A) Uncompensated respiratory acidosis
B) Partially compensated respiratory acidosis
C) Fully compensated respiratory acidosis
D) Mixed respiratory and metabolic acidosis
CorreCt Answer: B
Rationale: The pH is low (acidosis), and the PaCO2 is high (the primary respiratory cause).
The HCO3 is also high (above normal), indicating the kidneys are trying to compensate by
retaining bicarbonate. Because the pH remains abnormal, the compensation is only partial.
Question 3
A patient is diagnosed with Syndrome of Inappropriate Antidiuretic Hormone (SIADH). Which of
the following laboratory findings would the nurse expect?
A) Hypernatremia and concentrated urine
B) Hyponatremia and diluted urine
C) Hyponatremia and concentrated urine
D) Hypernatremia and diluted urine
CorreCt Answer: C
Rationale: In SIADH, there is excessive release of ADH, causing the body to retain water.
This leads to dilutional hyponatremia (low sodium due to excess water) and paradoxically
concentrated urine (because the kidneys are reabsorbing water).
Question 4
A nurse is reviewing a complete blood count (CBC). Which finding would indicate that a patient
, is at the highest risk for spontaneous bleeding?
A) Hemoglobin of 8 g/dL
B) White blood cell count of 2,000 cells/µL
C) Platelet count of 15,000 cells/µL
D) Hematocrit of 30%
CorreCt Answer: C
Rationale: A normal platelet count is 150,000-450,000. A count below 20,000 significantly
increases the risk of spontaneous, life-threatening hemorrhage. The other values indicate
anemia and neutropenia, but not imminent spontaneous bleeding.
Question 5
A patient is receiving a blood transfusion and develops a fever, flank pain, and dark urine. The
nurse suspects which type of transfusion reaction?
A) Febrile non-hemolytic reaction
B) Allergic reaction
C) Acute hemolytic reaction
D) Transfusion-associated circulatory overload (TACO)
CorreCt Answer: C
Rationale: An acute hemolytic reaction, often caused by ABO incompatibility, is a medical
emergency. The destruction of red blood cells causes fever, flank pain, and hemoglobinuria
(dark urine), and can lead to shock and DIC.
Question 6
A patient with diabetes insipidus (DI) is expected to have which urinary output pattern?
A) Oliguria with highly concentrated urine
B) Massive polyuria with very dilute urine
C) Anuria with no urine output
D) Intermittent urinary output with normal specific gravity
CorreCt Answer: B
Rationale: Diabetes insipidus is caused by a deficiency of or resistance to ADH. Without
ADH, the kidneys cannot concentrate urine, leading to the excretion of large volumes (polyuria)
of very dilute urine, which can cause severe dehydration.
