A patient with a history of coronary artery disease experiences chest pain while walking. After taking sublingual nitroglycerin, the patient’s chest pain increases, and they experience clammy skin and blurry vision.

They call 911 and you are the nurse attending to them in the emergency department. What is the most important nursing intervention to do first?

Choice A rationale
Sinus tachycardia is a regular, rapid heart rate caused by rapid firing of the sinoatrial node. It is characterized by a heart rate of greater than 100 beats per minute, and P waves are present before each QRS complex. This does not match the description given.
Choice B rationale
Ventricular tachycardia is a fast, regular beating of the ventricles that may last for only a few seconds or for much longer. In this condition, the ventricular rate is often between 120 and 200 beats per minute, and P waves are not associated with the QRS complexes. This matches the description given.
Choice C rationale
Ventricular fibrillation is a severe condition in which the heart beats with rapid, erratic electrical impulses. This causes the ventricles to quiver uselessly instead of pumping blood. The description does not match this condition.
Choice D rationale
Atrial flutter is a condition that shares similarities with atrial fibrillation, both involve an irregular heartbeat. However, atrial flutter is more organized and less chaotic than atrial fibrillation, which can make it more manageable. The description does not match this condition.

Choice A rationale
Anxiety is a common response to the stress of hospitalization and illness, especially in the context of a serious condition like ST-segment-elevation myocardial infarction (STEMI).
However, while anxiety can exacerbate physical symptoms and should be addressed, it is not the primary problem in this scenario.
Choice B rationale
Acute pain is a common symptom of STEMI, as the heart muscle is deprived of oxygen. However, the patient’s blood pressure and heart rate readings suggest a more immediate concern related to the cardiovascular system.
Choice C rationale
Decreased cardiac output is likely the priority problem for this patient. The patient’s low blood pressure (86/40 mm Hg) and high heart rate (132 beats/min) suggest that the heart is not pumping enough blood to meet the body’s needs, which is a direct consequence of the STEMI1. This can lead to organ failure and other serious complications if not addressed promptly.
Choice D rationale
Stress management is an important aspect of long-term care for patients with heart disease, as chronic stress can contribute to further heart damage. However, in the acute phase of a STEMI, the focus is on stabilizing the patient’s condition and preventing complications.
