Metabolic Crises
Q1: A 19-year-old patient with Type 1 diabetes presents with polyuria, polydipsia, and fruity
breath odor. Blood glucose is 420 mg/dL and arterial pH is 7.26. Which condition is present?
A. Hyperosmolar hyperglycemic state
B. Thyroid storm
C. Diabetic ketoacidosis
D. Adrenal crisis
Correct Answer: A
Rationale: Diabetic ketoacidosis is characterized by absolute insulin deficiency leading to
hyperglycemia, ketone production, and metabolic acidosis with a pH below 7.30. The fruity
breath odor results from exhalation of acetone, a volatile ketone body that accumulates when
insulin deficiency promotes lipolysis and hepatic ketogenesis. Correct because the triad of
hyperglycemia, ketonemia with fruity breath, and metabolic acidosis defines diabetic
ketoacidosis.
,Q2: A patient with cirrhosis and recurrent hepatic encephalopathy is prescribed rifaximin. Which
mechanism explains the therapeutic benefit of this medication?
A. Increased hepatic conversion of ammonia to urea
B. Enhanced renal excretion of ammonia
C. Acidification of the colonic lumen
D. Reduction of ammonia-producing gut bacteria
Correct Answer: D
Rationale: Rifaximin is a minimally absorbed oral antibiotic that reduces the population of
intestinal flora responsible for generating ammonia from dietary protein and endogenous
nitrogenous compounds. By decreasing the bacterial load in the gut, rifaximin synergizes with
lactulose to lower systemic ammonia levels and prevent recurrent episodes of hepatic
encephalopathy. Correct because decreasing ammonia-producing gut bacteria is the primary
mechanism by which rifaximin improves encephalopathy control.
Q3: A patient with Graves disease presents with temperature 40.2°C, heart rate 164 beats per
minute, severe agitation, and diarrhea after an iodinated contrast computed tomography study.
Which condition is present?
A. Myxedema coma
B. Adrenal crisis
C. Thyroid storm
D. Hepatic encephalopathy
Correct Answer: C
Rationale: Thyroid storm is a life-threatening exacerbation of hyperthyroidism characterized by
extreme hyperpyrexia, tachycardia, and neurologic dysfunction. Exposure to iodinated contrast
media is a recognized precipitating trigger that provides substrate for accelerated thyroid
hormone synthesis in patients with autonomous thyroid tissue. Correct because the combination
of severe fever, extreme tachycardia, and agitation following iodine exposure is diagnostic of
thyroid storm.
, Q4: A patient with septic shock develops acute respiratory distress syndrome, oliguria, and
thrombocytopenia. Which syndrome is evolving?
A. Cushing syndrome
B. Multi-organ dysfunction syndrome
C. Systemic lupus erythematosus
D. Addison disease
Correct Answer: B
Rationale: Multi-organ dysfunction syndrome is defined as the progressive failure of two or
more distinct organ systems, most commonly triggered by untreated septic shock. The sequence
of pulmonary failure followed by renal and hematologic dysfunction reflects the typical pattern
of organ involvement in MODS. Correct because the progressive failure of multiple organ
systems defines MODS.
Q5: A patient with decompensated cirrhosis exhibits worsening mental status. Which assessment
findings are consistent with hepatic encephalopathy? Select all that apply.
A. Hypertension and bounding peripheral pulses
B. Asterixis with wrist extension
C. Fetor hepaticus on exhalation
D. Hyperactive bowel sounds with diarrhea
E. Confusion and disorientation to time and place
Correct Answer: B, C, E
Rationale: Asterixis is the pathognomonic flapping tremor caused by ammonia-induced
neurotransmitter imbalance in the basal ganglia and is the hallmark motor sign of hepatic
encephalopathy. Fetor hepaticus is a musty sweet breath odor resulting from volatile sulfur
compounds that accumulate when the failing liver cannot detoxify gut-derived mercaptans.
Confusion and disorientation reflect early cerebral edema and altered neurotransmission caused
by ammonia crossing the blood-brain barrier and disrupting astrocyte function. Correct because
these three findings are classic clinical manifestations that establish the diagnosis of hepatic
encephalopathy.
