Final answer:
A score of 0 to 3 on the Colorado State University pain scale signifies that a patient's pain has been effectively managed, indicating successful pain reduction after medication.
Step-by-step explanation:
According to the Colorado State University pain scale, an effectively managed pain would be indicated by a score that is low, specifically in the 0 to 3 range. In a scenario depicted by a study investigating the effectiveness of pain-reducing medication, it is shown that a lower score after taking the medication corresponds to less pain and thus signifies effective pain management. If the alternative hypothesis is negative, it represents an improvement in the patient's condition, meaning the medication has successfully reduced the pain, resulting in a lower pain score. Hence, if the score descends from a higher value to within the range of 0 to 3 after the administration of pain medication, it can be concluded that the patient's pain has been effectively managed.
According to the Colorado State University pain scale, a score of 0 indicates that the patient's pain has been managed effectively. This means that the patient is not experiencing any pain. The scale ranges from 0 to 10, with higher scores indicating higher levels of pain.
