Which of the following can result in pseudohyperkalemia?

Which lab results are most likely from a patient in diabetic ketoacidosis (DKA)?

Given the lab results, what is the calculated osmolality? Na140, K4.5, Cl101, HCO3 20, Glu 120, BUN 12, Cr 1.1

The cation with the highest intracellular concentration is:

The following ABG results would indicate which Acid/Base disorder? pH 7.53 pCO2 40  HCO3 35

A young female presents to the ER with injuries to her arm from a fall.  The initial examination shows increased heart rate and respirations due to her pain.  After given pain meds and while waiting she becomes hysteric, complains of increasing pain and is experiencing muscle cramps.  Her ABG results were as follows: pH =7.50, pO2 = 115, pCO2 = 29, HCO3 = 22 What can you conclude?

Free ionized calcium normally represents approximately what percentage of the total serum calcium?

Osmometry measures changes in colligative properties of solutions such as which of these?

A patient has an acidic pH, decreased HCO3, normal pCO2, and elevated anion gap. What’s wrong with the patient?

Monitoring anion gap is used mostly for
