The nurse is caring for a client with an acute myocardial infarction (AMI). What emergent procedure does the nurse anticipate the physician will order?

Choice A rationale
Providing a pressure-reducing mattress, while important for preventing pressure ulcers, is not directly related to improving gas exchange in the lungs. Therefore, it would be considered the least priority intervention for a nursing diagnosis of impaired gas exchange related to fluid in the alveoli.
Choice B rationale
Administering oxygen and monitoring for dry nasal mucus membranes is a crucial intervention for a patient with impaired gas exchange. Oxygen therapy can help increase the amount of oxygen in the blood and alleviate symptoms of hypoxemia.
Choice C rationale
Encouraging the client to turn, deep breathe, cough, and use the incentive spirometer can help improve lung ventilation, promote the clearance of secretions, and prevent atelectasis, thereby improving gas exchange.
Choice D rationale
Placing the client in Fowler’s position can help improve lung expansion and gas exchange by reducing pressure on the diaphragm, making it easier for the patient to breathe.

Choice A rationale
Stable angina is characterized by chest pain that occurs with exertion and is relieved by rest. If a patient with angina pectoris is experiencing chest pain at rest and needs to take three nitroglycerin pills to relieve the pain, this is not typical of stable angina.
Choice B rationale
A full-blown acute myocardial infarction (MI), or heart attack, typically presents with severe chest pain, shortness of breath, and other symptoms. While chest pain at rest could be a symptom of an MI, other symptoms would likely be present.
Choice C rationale
Unstable angina is characterized by chest pain that occurs at rest, is severe and prolonged, and is not relieved by nitroglycerin. Therefore, a patient with angina pectoris who is experiencing chest pain at rest and needs to take three nitroglycerin pills to relieve the pain could be experiencing unstable angina.
Choice D rationale
Pulmonary embolus, a blockage in one of the pulmonary arteries in the lungs, typically presents with sudden-onset shortness of breath, chest pain that may become worse upon deep breathing or coughing, and other symptoms. Chest pain at rest could be a symptom of a pulmonary embolus, but other symptoms would likely be present.
