When planning care for a client receiving intravenous morphine sulfate for cancer pain, which action is the highest priority?

Monitoring respiratory status is the highest priority when planning care for a client receiving intravenous morphine sulfate for cancer pain due to the effects of opioids on the respiratory system. Morphine is an opioid analgesic that can cause respiratory depression, which is a potentially life-threatening side effect. Opioids depress the central nervous system, which can reduce the drive to breathe and lead to inadequate oxygenation.

In the context of pain management, especially with a potent medication like morphine, it is crucial to ensure that the client maintains adequate respiratory function. Therefore, regular assessment of the client’s respiratory rate, depth, and oxygen saturation levels is essential to identify any signs of respiratory compromise promptly.

While monitoring temperature, urine output, and encouraging increased fluids are important aspects of a holistic care plan, they do not take precedence over ensuring the client's respiratory status is stable. Any significant change in respiratory status can warrant immediate intervention and needs to be prioritized over other assessments related to fluid balance or general well-being.
