What current assessment finding would warrant the discontinuation of morphine every 2 hours?

The decision to discontinue morphine every 2 hours is significantly influenced by the client's respiratory rate of 11 breaths per minute. Morphine is an opioid analgesic known to cause respiratory depression as a common adverse effect. A respiratory rate at or below 12 breaths per minute is typically considered a point of concern, as it suggests the client may be experiencing respiratory distress due to opioid administration.

Respiratory depression can lead to inadequate ventilation and result in serious complications, such as hypoxia. Therefore, in the context of ongoing morphine therapy, a respiratory rate of 11/min is a clear indication that the client may not be managing the opioid well, and immediate reevaluation of the medication dosage or its continuation is necessary to ensure the client's safety.

While the other assessment findings also warrant attention, they do not pose the same immediate risk associated with respiratory function. For example, burning during injection could indicate a local reaction but is not as critical as respiratory depression. Similarly, dizziness when standing and a blood pressure of 106/68 mm Hg may signal hypotension and require monitoring but are not as urgent as the respiratory rate concerning morphine use. Thus, the respiratory rate is the most concerning assessment finding in this scenario.
