Final answer:
The emergency nurse would anticipate administering medications such as beta-blockers, among others, to a patient with aortic dissection.
Step-by-step explanation:
The symptoms described by the patient, such as substernal chest pain radiating into her back, cough, shortness of breath, high blood pressure, and increased heart rate, are consistent with an aortic dissection.
Therefore, the emergency nurse would anticipate administering medications such as beta-blockers, which help lower blood pressure and heart rate to prevent further complications in a patient with an aortic dissection.
Other medications that may be administered include pain relievers, antihypertensives, and anti-anxiety medications.
