Final answer:
To determine if an analgesic is effective for a 22-month-old child with broken ribs, assess the child's pain level before and after medication, observe their behavior, and communicate with their healthcare provider.
Step-by-step explanation:
An effective way to determine if an analgesic is working for a 22-month-old child with broken ribs is to assess the child's pain level before and after administration of the medication. One way to measure pain in young children is by using a pain scale specifically designed for their age group. For example, the FLACC (Face, Legs, Activity, Cry, Consolability) scale is commonly used to assess pain in infants and toddlers.
Additionally, observing the child's behavior can provide important insights into the effectiveness of the analgesic. If the child becomes calmer, more comfortable, and shows signs of decreased distress and improved sleep, it is likely that the medication is working.
Regular communication with the child's healthcare provider is crucial to monitor the child's progress and ensure that the analgesic is providing the desired pain relief.
