The nurse explains to a client that the drug administration of a medication is to be placed between the gum and jaw. By which route is the nurse administering this medication?

Choice A reason: Fentanyl patches provide continuous opioid delivery for 72 hours; their fixed schedule isn’t “as needed,” making them unsuitable for acute, variable pain management.

Choice B reason: Acetaminophen with oxycodone is scheduled every 6 hours; this fixed interval lacks the flexibility of “as needed,” limiting its use for breakthrough pain relief.

Choice C reason: Morphine extended-release is designed for sustained release over 12 hours; its fixed dosing isn’t “as needed,” restricting its role to chronic, not acute, pain control.

Choice D reason: Ketorolac IV every 4 hours prn allows flexible dosing; this NSAID targets inflammation and pain acutely, ideal for as-needed administration within safe limits.

Choice A reason: While reliability exists, the oral route is less predictable than IV administration due to variability in absorption caused by digestive factors, making it less reliable for rapid or consistent onset.

Choice B reason: Convenience is the primary advantage of oral administration. It allows ease of self-administration, enabling clients to manage their medications without healthcare provider intervention, making it the most frequently used route.

Choice C reason: While many clients tolerate oral medications well, others may face challenges, such as difficulty swallowing or gastric irritation, meaning tolerability varies and is not a universal advantage of this route.

Choice D reason: The oral route does not ensure fast action due to time required for digestion, absorption, and metabolism, making it slower compared to routes like IV or sublingual administration.
