Explore the factors underlying the client's anxiety.

When caring for a patient with leg ulcers, the positioning of the legs depends on whether the patient's ulcer is arterial or venous in origin. How should the nurse position a patient who has leg ulcers that are venous in origin? Elevate the patient's lower extremities. Hang the patient's legs over the side of the bed Keep the patient's knees at a 45-degree angle. Keep the patient's legs flat without the knees raised.

Elevate the patient's lower extremities.

The client exhibits a heart rate above 100 beats/minute. The client demonstrates ability to tolerate more activity without chest pain.

The client demonstrates ability to tolerate more activity without chest pain.

A patient with coronary artery disease (CAD) is having a cardiac catheterization. What indicator is present for the patient to have a coronary artery bypass graft (CABG)? The patient has compromised left ventricular function. The patient has had angina longer than 3 years. The patient has an ejection fraction of 65%. The patient has at least a 70% occlusion of a major coronary artery.

The patient has at least a 70% occlusion of a major coronary artery.

Family members bring a client to the ED with pale cool skin, sudden midsternal chest pain unrelieved with rest, and a history of CAD. How should the nurse best interpret these initial data? The symptoms indicate angina and should be treated as such. The symptoms indicate an acute coronary episode and should be treated as such. Treatment should be determined pending the results of an exercise stress test. The symptoms indicate a pulmonary etiology rather than a cardiac etiology.

The symptoms indicate an acute coronary episode and should be treated as such.

The client has had biomarkers tested after reporting chest pain. Which diagnostic marker of myocardial infarction remains elevated for as long as 2 weeks? CK-MB Total creatine kinase Troponin Myoglobin

Troponin

A client is admitted to the emergency department with chest pain and doesn't respond to nitroglycerin. The health care team obtains an electrocardiogram and administers I.V. morphine. The health care provider also considers administering alteplase. This thrombolytic agent must be administered how soon after onset of myocardial infarction (MI) symptoms? Within 6 hours Within 24 to 48 hours Within 12 hours Within 5 to 7 days

Within 6 hours For the best chance of salvaging the client's myocardium, a thrombolytic agent must be administered within 6 hours after onset of chest pain or other signs or symptoms of MI. Sudden death is most likely to occur within the first 24 hours after an MI. Health care providers initiate I.V. heparin therapy after administration of a thrombolytic agent; it usually continues for 5 to 7 days.

A 60-year-old woman has been brought to the emergency department (ED) by ambulance after she experienced a sudden onset of dyspnea and phoned 911. The woman is obese but claims an unremarkable medical history and denies chest pain. When assessing this patient, the nurse in the ED should be aware that: Acute coronary syndrome (ACS) manifests with chest pain rather than with shortness of breath. Women often present with an MI much differently than do men. The absence of known risk factors usually rules out myocardial infarction (MI) or angina as a cause of dyspnea. Dyspnea is definitive for a respiratory, rather than cardiac, etiology.

Women often present with an MI much differently than do men.
