how does the nurse identify a bruit during a cardiac assessment?

presence of swishing sounds

which body system does the cardiovascular (CV) system work in conjunction with to meet the human need for oxygenation and tissue perfusion?

respiratory

The nurse is teaching a patient about the purpose of electrophysiology studies (EPS). Which statement by the nurse reflects the most correct teaching?

"This test evaluates you for potentially fatal cardiac rhythms."

the nurse is caring for a pt with mitral valve prolapse who asks about the purpose of the mitral valve. How should the nurse respond?

"located between the left atrium and the left ventricle, it prevents blood from flowing back into the atrium during systole"

what is the average pressure of blood in the right atrium (RA)?

0-5 mm Hg

while caring for a pt with cardiovascular disease (CVD), the nurse recognizes the pt is at risk for decreased cardiac output (CO). Which finding supports the nurses observation?

Cardiac output (CO) or 3L/min

a student nurse is discussing the characteristics of cardiac muscle cells with other students. Which characteristic of cardiac cell muscles is least likely to be important during this discussion?

Elasticity Elasticity. is not a characteristic of cardiac muscle cells; it is a characteristic of skeletal muscle cells. The characteristics of cardiac muscle cells include contractility, automaticity, and refractoriness.

Peripheral chemoreceptors

which term is used to refer to the degree of myocardial fiber stretch at the end of diastole and just before contraction?

Preload

Which statement regarding atrioventricular (AV) valves and semilunar valves of the heart is true?

Semilunar valves prevent blood from flowing back into the ventricles during diastole

The nurse is caring for a patient admitted with pericarditis. Which symptom does the nurse anticipate the patient will report?

Substernal chest pain described as sharp and stabbing

the nurse anticipates finding a bounding or hyperkinetic pulse in the pt with which disorder or condition

Which type of edema causes the nurse to suspect chronic venous insufficiency in a patient?

bilateral edema of the legs

A patient is brought to the emergency department for chest pain that began 30 minutes ago. Upon assessment, the patient says to the nurse, "The pain is gone now; it was a false alarm. I need to get back to mowing the lawn." Which response best describes the patient's statements?

denial

How does the nurse classify the patient with cardiovascular disease who experiences fatigue and palpitations with ordinary physical activity as per the New York Heart Association functional classification system?

class II

Which disease or occurrence is the leading cause of death in adults?

heart disease

cardiac output is represented by which formula?

heart rate x stroke volume

Which statement about fatigue is correct?

it is a feeling of tiredness or weariness resulting from activity fatigue is a feeling of tiredness or weariness resulting from activity. a brief loss of consciousness is referred to as syncope. Dyspnea refers to difficult or labored breathing. Palpitation is a feeling of fluttering or unpleasant felling in the chest caused by an irregular heartbeat.

A patient recovering from cardiac angiography develops slurred speech. What does the nurse do first?

performs a complete neurological assessment and notifies healthcare provider

A patient on a telemetry unit is scheduled for electrophysiologic studies (EPS). Which condition does the patient likely have?

post sudden cardiac arrest

which structure of the heart is responsible for receiving deoxygenated venous blood as well as the blood from the heart muscle?

right atrium
