CCRN

A comprehensive study of CCRN, covering critical care nursing concepts from basics to advanced applications.

Renal and Metabolic Emergencies

Kidneys and Metabolism in Crisis

Critical illness can damage the kidneys or throw off the body's balance of fluids and electrolytes.

Recognizing Emergencies

  • Acute kidney injury: Sudden loss of kidney function.
  • Electrolyte imbalances: Problems with sodium, potassium, or calcium can cause dangerous heart rhythms or organ failure.
  • Metabolic acidosis/alkalosis: The body’s acid-base balance goes haywire.

Interventions

Nurses monitor urine output, lab values, and watch for signs of swelling, confusion, or abnormal heart rhythms.

Real-World Challenge

A patient with sepsis develops high potassium and low urine output. The nurse notifies the doctor, prepares to administer medications, and sets up for emergency dialysis if needed.

Examples

  • A nurse recognizes peaked T waves on the EKG and suspects hyperkalemia.

  • A patient with diabetic ketoacidosis receives fluids and insulin while labs are closely watched.

In a Nutshell

Renal and metabolic problems require quick detection and intervention to prevent organ failure.
