Final answer:
The true statements concerning IV's for younger pediatric patients are the removal of air bubbles from IV tubing and the preference of microdrip over macrodrip tubing.
Step-by-step explanation:
Concerning younger pediatric patients and IV's, the statements that are true are that air bubbles must be removed from IV tubing and stopcocks and microdrip tubing is preferred to macrodrip tubing. Air bubbles can cause serious complications, such as air embolisms, which can be particularly dangerous in pediatric patients due to their small blood volume. Microdrip tubing allows for more precise control of fluid delivery which is essential in pediatric patients who often require very specific volumes of fluids and medications due to their small size. Buretrols, which are in-line chambers used with IV therapy, can be used with any age group, not just older children, as they allow for controlled administration of small volumes of fluid, making E) A and B only the correct answer.
