Question 1 of 11
1. Question
Which of the following electrolytes would be important when calculating an anion gap?
Correct
Answer – Anion gap = Sodium (Na+) – [Chloride (Cl-) + Sodium Bicarbonate (HCO3-)]; therefore, chloride would be the only important value in the ones listed when doing this calculation
Incorrect
Answer – Anion gap = Sodium (Na+) – [Chloride (Cl-) + Sodium Bicarbonate (HCO3-)]; therefore, chloride would be the only important value in the ones listed when doing this calculation

Correct
Answer – propofol is associated and can cause lactic acidosis.
Incorrect
Answer – propofol is associated and can cause lactic acidosis.

Question 3 of 11
3. Question
In a patient with a pH of 7.1 and an elevated anion gap, which of the following would best represent the situation?
Correct
Answer – with a lower pH and elevated, anion gap, this is indicative of a metabolic acidosis situation.
Incorrect
Answer – with a lower pH and elevated, anion gap, this is indicative of a metabolic acidosis situation.

Question 4 of 11
4. Question
Of the following agents, which has a boxed warning for lactic acidosis?
Correct
Answer – there are numerous HIV medications that have a boxed warning for lactic acidosis. Didanosine is one of them that carries this risk.
Incorrect
Answer – there are numerous HIV medications that have a boxed warning for lactic acidosis. Didanosine is one of them that carries this risk.

Question 5 of 11
5. Question
Which of the following would not likely be a potential issue with a severely alkalosis state?
Correct
Answer – while there might be a very slight chance of edema if the alkalosis causes changes in cardiac output, the higher and more likely concerns with an alkalosis state include electrolyte imbalances and neurologic symptoms like seizures, confusion, and sedation
Incorrect

Incorrect
Answer – Causes of anion gap metabolic acidosis include Methanol, Uremia, Diabetic ketoacidosis, Paraldehyde, Iron overdose, Lactic acidosis, Ethylene glycol, and Salicylates.

Question 7 of 11
7. Question
Hyperventilation and mineralcorticoid excess would be more likely to cause?
Correct
Answer – hyperventilation allows us to blow off CO2 which in turn can result in an alkalosis state. Mineralcorticoid excess has been known to contribute to metabolic alkalosis.
Incorrect
Answer – hyperventilation allows us to blow off CO2 which in turn can result in an alkalosis state. Mineralcorticoid excess has been known to contribute to metabolic alkalosis.

Question 8 of 11
8. Question
Which of the following would not be a goal of therapy in an acidosis state?
Correct
Answer – TPN administration would not necessarily be important and would not be a goal of therapy in correcting an acidotic state.
Incorrect
Answer – TPN administration would not necessarily be important and would not be a goal of therapy in correcting an acidotic state.

Question 9 of 11
9. Question
Which of the following would be most likely to cause a non-anion gap metabolic acidosis?
Correct
Answer – A non-anion gap metabolic acidosis can be caused by hyperkalemia, bicarb loss secondary to renal insufficiency, fistulas, and diarrhea. Opioids would be more likely to cause respiratory acidosis by shutting down the respiratory tract and causing hypoventilation. Methanol and Iron toxicity would represent an anion-gap metabolic acidosis.

Question 10 of 11
10. Question
Which of the following calculated anion gap value would represent an anion gap metabolic acidosis?
Correct
Answer – An elevated anion gap is indicative of this type of metabolic acidosis. Levels greater than 16 mEq/L are typically considered a sufficient anion gap.
Incorrect
Answer – An elevated anion gap is indicative of this type of metabolic acidosis. Levels greater than 16 mEq/L are typically considered a sufficient anion gap.

Question 11 of 11
11. Question
Which of the following medications could contribute to a lactic acidosis situation?
Correct
Answer – While rare, metformin can contribute and cause lactic acidosis. Risk is increased in the elderly and as renal function declines.
Incorrect
Answer – While rare, metformin can contribute and cause lactic acidosis. Risk is increased in the elderly and as renal function declines.
