مريض يأخذ فوروسيمايد، البوتاسيوم عنده ٢٫٩ مع ضعف عضلي وظهور موجة U في التخطيط، والطبيب وصف كلوريد البوتاسيوم ٢٠ ملمول وريدياً. ما طريقة الإعطاء الصحيحة؟

A client on furosemide has potassium 2.9 mmol/L with muscle weakness and U waves on the ECG. The provider orders potassium chloride 20 mmol IV. How should it be given?

1. Intramuscularly in the gluteal muscle to avoid phlebitis
2. As a slow IV push over 5 minutes directly through the cannula
3. Diluted, by pump, at no more than 10 mmol/h peripherally
4. Added to the hanging bag, mixed by inverting, then run at any rate

Answer: C) Diluted, by pump, at no more than 10 mmol/h peripherally. IV potassium is never given as a push because it can stop the heart. It is diluted and pumped, usually no faster than 10 mmol/h peripherally. Adding it to a hanging bag may not mix well and can deliver a concentrated bolus, and it is not given IM.
