Final answer:
For a case of hypokalemia, an aide might grab an IV bag from a supply cabinet containing 100 mL of 0.5% KCl as ordered by a physician to quickly address the patient's low potassium levels.
Step-by-step explanation:
When a patient is suffering from hypokalemia, which is a condition characterized by low potassium levels in the blood, a physician may order an intravenous (IV) delivery of a potassium chloride (KCl) solution to correct the electrolyte imbalance. If a physician orders an IV delivery of 100 mL of 0.5% KCl, it is indeed possible that an aide would run to a supply cabinet to retrieve an IV bag containing this specific concentration of KCl. Hospitals typically have a variety of IV solutions with different concentrations on hand to address a range of patient needs quickly and efficiently. The aide would need to check the label on the IV bag to determine the concentration of KCl it contains. If the concentration is different from 0.5%, the aide would need to prepare the correct solution by diluting or concentrating the KCl solution as necessary.
