Final answer:
Certain medications should and should not be coadministered with gas induction. Propofol is an example of a medication that should be coadministered, while muscle relaxants should not be coadministered.
Step-by-step explanation:
When using gas induction for anesthesia, certain medications should and should not be coadministered. One example of a medication that should be coadministered with gas induction is a short-acting intravenous anesthetic called propofol. Propofol is commonly used to induce anesthesia before switching to inhalational anesthetics. On the other hand, medications that should not be coadministered with gas induction include muscle relaxants, as they can interfere with the gas induction process.
