Your critical care transport team is carrying a 35-year-old male who has sustained bilateral femur fractures in a rollover motor vehicle collision to a tertiary care facility. The patient never required resuscitation and remained hemodynamically stable through his entire stay at the community hospital from which you are transporting him. During his care there, he had bilateral traction splints applied, two large-bore IVs established, blood type cross-matched, and supplemental oxygen administered by 100% nonrebreathing mask. The physical exam reveals a patient who is in moderate/severe pain and in distress secondary to the fractures. He is alert and oriented times 3, restless, and anxious. Lungs are clear bilaterally. Heart sounds are good. Both traction splints are in place with good distal dorsalis pedis and posterior tibialis pulses, good distal sensory checks, and range of motion of the feet and toes. Most recent vital signs are blood pressure, 122/68 mm Hg; heart rate, 102 beats/min; respirations, 22 breaths/min; SpO2, 100%. Your standing orders call for administration of fentanyl (Sublimaze) 1 μg/kg, which is 100 μg for this patient. Which of the following statements is true regarding this medication for this patient?
