Final answer:
Nursing assistants might be tasked with preparing IV solutions under a registered nurse's supervision, involving tasks like dilution calculations for proper concentrations and adhering to strict safety protocols.
Step-by-step explanation:
The responsibility of a nursing assistant in relation to checking IV flow rates is typically under the direct supervision of a registered nurse. The primary role of a nursing assistant focuses on providing direct patient care, which can include tasks such as taking and reporting a patient's vital signs and preparing solutions and equipment for dialysis treatments. However, when it comes to IV therapy, the responsibility of preparing and administering an IV solution such as diluting a potassium chloride (KCl) stock solution to a particular concentration falls under the scope of a nursing assistant. In this case, the aide must perform a dilution calculation to ensure the correct concentration is administered. Furthermore, adherence to safety protocols such as a checklist, much like the one proposed by Dr. Pronovost, is essential to ensure that each step of the procedure is followed accurately.
