Final answer:
The described scenario of a nurse's interactive and adaptive approach to patient care is an example of the Dynamic descriptor of the nursing process.
Step-by-step explanation:
The scenario described of a nurse interviewing a pregnant teenager and documenting her answers while also addressing the client's concerns and making appropriate referrals fits with the dynamic descriptor of the nursing process. This descriptor refers to the nursing process being ever-changing and adaptable as the nurse interacts with the patient. In this case, the nurse is actively engaging with the teenager to assess and meet her needs, which may evolve during their interaction. Therefore, the correct answer to which descriptor of the nursing process is exemplified is Dynamic (Option B).
