What rate indicates a complication for an adolescent receiving fentanyl via an epidural catheter postoperatively?

The correct choice indicates a respiratory rate of 12 breaths per minute as potentially alarming for an adolescent receiving fentanyl via an epidural catheter. When assessing opioid administration, especially in a postoperative setting, monitoring respiratory rate is crucial, as opioids like fentanyl can cause respiratory depression—a serious complication.

A respiratory rate of 12/min is on the lower end of the normal range for adolescents, which typically is around 12 to 20 breaths per minute. While it is not automatically indicative of a complication, it can be seen as a threshold where further monitoring and assessment are necessary. A rate significantly below this range could signal respiratory distress or compromise, often requiring intervention, such as supplemental oxygen or reversal agents.

Rates higher than this, such as 14/min, 16/min, or 20/min, would generally be considered safe and within normal limits for typical adolescent respiration, indicating the body is adequately ventilating and reacting appropriately to the medication administered.
