Final answer:
The most critical finding to report for a client who received morphine IV is a respiratory rate of 11/min, as it indicates a potential life-threatening respiratory depression.
Step-by-step explanation:
A nurse is collecting data from a client who received morphine IV for pain relief and needs to determine which of the following findings is a priority to report to the provider. Between emesis, sedation, a respiratory rate of 11/min, and a blood pressure of 90/54 mm Hg, the most critical finding to report would be a respiratory rate of 11/min. Morphine is a potent opioid analgesic that can cause respiratory depression, which is a potentially life-threatening side effect. A normal adult respiratory rate is typically between 12 to 20 breaths per minute, so a rate of 11/min is low and indicative of respiratory depression. This requires prompt intervention to avoid further decline in the client's respiratory status.
