@nursing.with.beatrice: Can you identify the electrolyte imbalance from this ECG? Look closely at the strip: * ST-segment depression * shallow/flattened T waves * prominent U waves These findings point toward hypokalemia, not hyperkalemia. Why? Hypokalemia lowers serum potassium and changes cardiac repolarization, which is why you may see flattened T waves, ST depression, and a visible U wave after the T wave. Why not the others? * Hyperkalemia typically causes tall peaked T waves, and in severe cases may lead to widened QRS complexes. * Hypercalcemia is more associated with a shortened QT interval. * Hypocalcemia is more associated with a prolonged QT interval. Clinical reminder: Hypokalemia can increase the risk of dysrhythmias, especially if severe or if the patient is also taking digoxin. Drop your answer and rationale before checking the caption. Correct answer: Hypokalemia #NursingWithBeatrice #NCLEX #NCLEXPrep #CardiacRhythm #ECGInterpretation
