Question

During the acute phase of burn injury, the nurse knows to assess for signs of potassium shifting during what time frame?

A. Within 24 hours.
B. Between 24 and 48 hours.
C. At the beginning of the third day.
D. Beginning on day 4 or day 5.

Answer 1

Nurses should monitor for signs of potassium shifting within 24 hours of a burn injury, because damaged cells may release potassium into the extracellular space, impacting cardiac and muscle function.

Step-by-step explanation:

During the acute phase of a burn injury, it is crucial for nurses to monitor for signs of potassium shifting. This is because damage to cells can cause intracellular contents, including potassium, to leak into the extracellular space. The correct time frame for a nurse to assess for signs of potassium shifting is within 24 hours following the injury. This monitoring is vital as changes in potassium levels can impact cardiac and muscular function, and can be potentially life-threatening if not managed properly.
