Final answer:
The nurse has followed the principle of right task.
Step-by-step explanation:
The correct answer is 1. The nurse has followed the principle of right task.
Delegation is an important skill for registered nurses (RNs) to effectively manage their workload and ensure patient care needs are met. The principle of right task means that the RN has assessed the task, determined that it can be safely delegated to the nursing assistive personnel (NAP), and ensured that the NAP has the necessary training and competence to perform the task. In this case, the RN has delegated the duty of measuring blood pressure to the NAP, who has been trained in this skill.
