A nurse on a medical-surgical unit is caring for a client who reports pain in the jaw, back, and shoulder, and shortness of breath and nausea. Which of the following actions should the nurse take?

Choice A reason: Administering ibuprofen may mask symptoms and delay diagnosis. It is not appropriate without further assessment. Choice B reason: Maintaining oxygen saturation is important, but this is a supportive measure, not a diagnostic priority. Choice C reason: Acetaminophen may reduce discomfort but does not address the potential underlying cardiac issue. Choice D reason: The client’s symptoms are classic for myocardial infarction, especially in women. An EKG is the priority diagnostic test to assess for cardiac ischemia.
