Primary treatment for myocardial infarction (MI) is directed at

decreasing myocardial oxygen demands.

Aortic regurgitation is associated with

diastolic murmur

A patient presents to the emergency department with a diastolic blood pressure of 132 mm Hg, retinopathy, and symptoms of an ischemic stroke. This symptomology is likely the result of

hypertensive crisis.

Constrictive pericarditis is associated with

impaired cardiac filling

Hypertension is closely linked to

obstructive sleep apnea

A patient with significant aortic stenosis is likely to experience

syncope.

Pulse pressure is defined as

systolic pressure - diastolic pressure.

A middle-aged patient has a follow up visit for a recorded blood pressure of 162/96 mm Hg taken 3 weeks ago. The patient has no significant past medical history and takes no medications, but smokes 1 1/2 packs of cigarettes per day, drinks alcohol regularly, and exercises infrequently. The patient is about 40 lbs. overweight and admits to a high-fat, high-calorie diet. At the office visit today, the patient's blood pressure is 150/92 mm Hg. What is the least appropriate intervention for this patient at this time?

Begin antihypertensive drug therapy

A patient is diagnosed with cardiogenic shock. The patient is hyperventilating and is therefore at risk for the respiratory complication of respiratory acidosis.

False A patient diagnosed with cardiogenic shock who is hyperventilating is at risk for respiratory alkalosis.

What compensatory sign would be expected during periods of physical exertion in a patient with limited ventricular stroke volume?

Tachycardia

The most commonly recognized outcome of hypertension is pulmonary disease.

False

While hospitalized, an elderly patient with a history of myocardial infarction was noted to have high levels of low-density lipoproteins (LDLs). What is the significance of this finding?

Increased LDL levels are associated with increased risk of coronary artery disease.

The majority of cardiac cells that die after myocardial infarction do so because of

apoptosis.

After being diagnosed with hypertension, a patient returns to the clinic 6 weeks later. The patient reports "moderate" adherence to the recommended lifestyle changes and has experienced a decreased from 165/96 to 148/90 mm Hg in blood pressure. What is the most appropriate intervention for this patient at this time?

Continue lifestyle modifications only.

Mitral stenosis is associated with

a pressure gradient across the mitral valve.

An elderly patient's blood pressure is measured at 160/98. How would the patient's left ventricular function be affected by this level of blood pressure?

Left ventricular workload is increased with high afterload.

Angina caused by coronary artery spasm is called _____ angina

Prinzmetal variant

Myocarditis should be suspected in a patient who presents with

acute onset of left ventricular dysfunction.

Critically ill patients may have parenterally administered vasoactive drugs that are adjusted according to their _____ pressure.

mean arterial

The ingestion of certain drugs, foods, or chemicals can lead to secondary hypertension.

True
