Final answer:
The nurse should consult with the physician, verify the availability of the required IV bag, and request an alternative solution if necessary.
Step-by-step explanation:
The nurse should take the following actions next:
- Consult with the physician about the order for an intravenous (IV) delivery of 100 mL of 0.5% KCl for the patient suffering from hypokalemia (low potassium levels).
- Verify the availability of an IV bag containing this concentration of KCI in the supply cabinet.
- If the IV bag is not available, inform the physician and request an alternative solution to address the patient's low potassium levels.
