While the nurse is obtaining a health history, the client reports experiencing shortness of breath at times. The nurse determines that the client's respirations are regular and deep and respiratory rate is 14 breaths/minute. Which is the best nursing action?

A. Explain to the client the possible causes of dyspnea or "shortness of breath.": While the nurse might eventually explain this, it's premature without more information about the client's specific shortness of breath experience.B. Ask the client to describe the episodes of dyspnea in more detail: This is the most appropriate next step. Understanding the characteristics, triggers, and severity of the dyspnea will help determine the cause and guide further assessment.C. Document "dyspnea on exertion" in the client's medical record: The client only reports experiencing shortness of breath "at times," not necessarily with exertion. More details are needed before documenting.D. Ask the client to perform light exercise and observe the respiratory effort: This could worsen the client's condition if the shortness of breath is severe. Observation during rest provides a safer approach initially.
