Final answer:
Options 1 and 2 support the effectiveness of the risk management plan, while options 3 and 4 suggest ineffectiveness.
Step-by-step explanation:
The question asks whether the risk management plan was effective. Options 1 and 2 both provide reasons supporting the effectiveness of the plan. Option 1 states that the pharmacy is administering the vaccinations, which can improve safety and ensure proper handling. Option 2 mentions the involvement of physicians verifying the vaccines, which adds an extra layer of safety. On the other hand, options 3 and 4 state reasons why the plan was ineffective. Option 3 highlights a failure in matching the order with the chosen vaccine, which can lead to errors. Option 4 mentions the need to retain packaging until the vaccine is administered, which suggests a potential flaw in the plan.
