Final answer:
Rebecca's ability to comfort Betty can be attributed to her emotional intelligence and personal attributes or her professionally acquired skills and clinical knowledge as a nurse.
Step-by-step explanation:
The ability of Rebecca to quickly calm Betty when others could not can be viewed in two different ways reflecting the nurse's power. One perspective may consider Rebecca's innate empathy and emotional intelligence which enables her to connect with and soothe Betty effectively. This view emphasizes the personal attributes and soft skills nurses possess that contribute to their caregiving capabilities.
Another interpretation might focus on the professionally acquired skills and techniques that Rebecca, as a nurse, might be employing. This encompasses the clinical knowledge and psychological strategies that nurses learn through training and experience, positioning them to manage patients' emotional and physical needs adeptly.
