You Are the Nurse Assigned to Care for a Child

You are the nurse assigned to care for a child on the pediatric unit. The lab calls with a potassium level of slightly over 5 milliequivalents per liter. This report comes just as you note a widened QRS complex on the electrocardiogram (EKG) . From this information, you realize this:

A) child has a slightly elevated potassium level and you should leave the pediatrician a note
B) could lead to cardiac arrest if not treated quickly
C) is a normal lab report and a slight deviation from a normal EKG
D) should be called to the attention of the oncoming nurse at the end-of-shift report
