Answer:
a. "I think the client would benefit from intravenous furosemide (Lasix)."
Explanation:
Communication between doctor and nurses regarding patients should follow the order: situation, background, evaluation and recommendations. Based on this, since the nurse has already reported the first three topics, the final communication step should be a recommendation on how to solve the patient's problem.
In the above case, the patient was diagnosed with dyspnea which is difficulty breathing, a condition usually related to heart and respiratory disease. A recommendation for this case is the use of intravenous furosemide to solve the patient's problem. In this case, the nurse should close the communication with the doctor with the phrase: "I think the client would benefit from intravenous furosemide (Lasix)."
