Today Pharmacy received an order for electrolytes (kcl and mgso4). the patient had severe electrolytes imbalance and the ICU physician ordered some corrective measures.

The order came as follows:
[20MEQs of KCL + 2GM of MgSO4] mixed to 200ML of D5W in 0.45% NACL.

Our pharmacy stock of Potassium chloride is from PSI factory in Jeddah, and it comes as 20MEQs in 10ML, Magnesium sulphate comes as 2.5GM in 5ML. The needed preparation was supposed to be mixed as follow:

  1. 1
    10ML of KCL that gives 20MEQs.
  2. 2
    4ML of MgSO4 that gives 2GM.
  3. 3
    186ML of D5W 0.45% NACL.

Physical Compatibility: Physically compatible. No visible haze or particulate formation, color change, or gas evolution.
Chemical Stability: Chemically stable. Less than 5% change in measured potassium and magnesium concentrations occurred in 24 hours.
Storage: Room temperature of 22 °C.

Pharmacist, CPHQ, CHQO, Quality Coordinator, Chemotherapy Preparation incharge. Graduated pharmacy school in 2009 I stood with my classmates as we recited the “Oath of a Pharmacist” in. There is one particular vow that stood out to me as we recited the Oath and I embrace this vow, “I will apply my knowledge, experience, and skills to the best of my ability to assure optimal outcomes for my patients.” I love being a pharmacist because it allows me to use my knowledge, abilities, and talents to improve patient outcomes in the community hospital in which I am employed as the pharmacy clinical coordinator.
