Case-2: Patient History
L.S. is brought to the emergency department for management of acute mushroom poisoning. Her respirations are slow and shallow, and she is nonresponsive. She is admitted to the critical care unit to be closely monitored for the development of respiratory failure and renal failure, which often accompany mushroom poisoning. Her urine output is decreased to about 20 ml/hr. Her laboratory values are serum K+ = 5.7 mEq/L; arterial blood gases (ABGs): pH = 7.13, PaCO2 = 56 mm Hg, PaO2 = 89 mm Hg, HCO3- = 18 mEq/L.
Analyze this case study and answer the next four questions that follow.
Case-2 Question-1
What is the most likely cause of L.S.âs potassium imbalance? (select all that apply)
The most likely cause of L.S.âs potassium imbalance is impaired kidney function.
The most likely cause of L.S.âs potassium imbalance is respiratory failure.
The most likely cause of L.S.âs potassium imbalance is her shallow breathing.
The most likely cause of L.S.âs potassium imbalance is renal failure.
Case-2: Question-2
What is the relationship between acid-base balance and serum potassium level? (select all that apply)
Acidosis contributes to hyperkalemia.
Alkalosis contributes to hypokalemia.
Acidosis contributes to hypokalemia.
Alkalosis contributes to hyperkalemia.
Case-2: Question-3
Categorize and explain the probable cause of L.S.âs acid-base disorder. (select all that apply)
L.S. has respiratory alkalosis.
L.S. has respiratory acidosis.
L.S. has metabolic alkalosis.
L.S. has metabolic acidosis.
Case-2: Question-4
Can L.S. compensate for her acid-base disorder? (select all that apply)
She can compensate by excreting more bicarbonate ions.
She can compensate by hypoventilation.
She will not be able to compensate on her own because the lungs and the kidneys are malfunctioning.
She can compensate by hyperventilation.
