The correct answer is C, you would administer 875 ml of the bag. The order has a safe rate and safe concentration, thus it can be administeredĢ. How much of the 1000ml bag of normal saline with 40 mEq/L of potassium chloride bag would you administer for this order? If we convert this max safe concentration from ml to L by multiplying 0.4 mEq/ml x 1000 ml/1L it converts to 400 mEq/L, thus the concentration we are using is also safe. As for the concentration, we know that the bag we are using to administer is 40 mEq/L of potassium chloride and the maximum safe concentration for potassium chloride when given via a central line is 0.4 mEq/ml. 17.5 mEq of potassium chloride/hr is less than the lowest maximum safe rate, thus the rate of this order is safe for this patient (note: you would also use the lower rate as the maximum safe rate). The maximum safe rate is 30 mEq/hr which is safe, however we need to determine that it is also safe for the patients weight, thus we will multiple 94kg into 0.5 mEq/kg/hr, which = 47 mEq/hr. If you are administering 35 mEq of potassium chloride over 2 hours you would divide 35 mEq by 2 hours, which would = 17.5 mEq of potassium chloride/hr. The correct answer is A, the rate is safe and the concentration is safe you can administer this medication. Is the order rate and concentration safe to administer?Ī) The rate is safe and the concentration is safe you can administer this medicationī) The rate is safe and the concentration is not safe do not administer this medicationĬ) The rate is not safe and the concentration is not safe do not administer this medicationĭ) The rate is not safe and the concentration is not safe do not administer this medicationĢ. Which of the following is the correct amount of the 1000ml bag of normal saline with 40 mEq/L of potassium chloride bag to administer for this order?ģ. Which of the following is the correct rate that you would administer this infusion at (round to the nearest whole number)? The maximum safe concentration for potassium chloride if given via a central line is 0.4 mEq/ml for intermittent infusions.ġ. Note: The maximum safe infusion rate for potassium chloride is 0.5 mEq/kg/hr with a maximum of 30 mEq/hr. Pharmacy delivers a 1000ml bag of normal saline with 40 mEq/L of potassium chloride to the unit to be administered to this patient. The physicians order states to administer 35 mEq of potassium chloride over 2 hours IV in normal saline via the patients PICC line. Use the following scenario to answer questions 1-3:Ī 40 year old adult patient who weighs 94 kg is prescribed a one time dose of IV potassium chloride for a serum blood potassium level of 2.8 mEq/L that was drawn this morning.
