What is the maximum single dose of Fentanyl citrate for an adult in this protocol?

• A. 50 mcg
• B. 200 mcg
• C. 75 mcg
• D. 100 mcg

Answer: (D)

Fentanyl citrate is extremely potent, so protocols cap the amount you can give in one adult dose to protect the patient from serious respiratory depression while still providing swift pain relief. In this protocol, a typical plan is to start with a small bolus and titrate up, but you may not exceed 100 mcg in a single administration. This 100 mcg limit reflects the balance between achieving analgesia quickly and minimizing the risk of adverse effects. If the patient still needs more pain control after reaching that limit, the protocol would guide you on the next steps rather than increasing a single dose beyond 100 mcg.
