Final answer:
Patients who self-administer morphine for pain require less medication than patients who receive injections from hospital staff.
Step-by-step explanation:
Patients who self-administer morphine for pain require less medication than patients who receive injections from hospital staff. When morphine is self-administered, patients have more control over the dosage and timing of their medication, which means they can adjust their dosage based on the severity of their pain. In contrast, when patients receive injections from hospital staff, they may receive a standard dosage that may not be tailored to their individual pain levels.
For example, a patient who self-administers morphine may start with a lower dosage if their pain is mild, and then increase the dosage if their pain becomes more severe. This allows them to effectively manage their pain without taking more medication than necessary.
On the other hand, patients who receive injections from hospital staff may be given a fixed dosage that may not fully address their pain. This could result in them requiring more medication to achieve the desired pain relief.
