Practice Question
The nurse caring for a client reviews the medical record and determines the client is at risk for developing a potassium deficit because of which situation?
Answer Choices:
Correct Answer:
Requires nasogastric suction.
Rationale:
🔷 NG suction leads to loss of gastric fluids, which are rich in potassium, causing hypokalemia.
🔷 Continuous suction removes hydrogen ions and potassium from the stomach and upper intestines.
🔷 Potassium loss affects neuromuscular and cardiac function, increasing the risk for arrhythmias.
🔷 Patients on NG suction require close electrolyte monitoring and potassium replacement as needed.
🔷 Early identification and correction of potassium deficit prevent complications like muscle weakness and respiratory distress.
