up into the:

• Aorta
• Left ventricle
• Pulmonary veins
• Right ventricle
• Right ventricle

A nurse is teaching about the heart. Which information should the nurse include? The chamber of the heart that

generates the highest pressure is the:

• Right atrium
• Left atrium
• Left ventricle
• Right ventricle
• Left ventricle

A nurse recalls the chamber that receives blood from the

systemic circulation is the:

• Right atrium
• Right ventricle
• Left atrium
• Left ventricle
• Right atrium

Which statement indicates the nurse understands blood

flow? Oxygenated blood flows through the:

• Superior vena cava
• Pulmonary veins
• Pulmonary artery
• Cardiac veins
• Pulmonary veins

The nurse is planning care for a patient with heart problems. Which information should the nurse remember? The _____ artery travels down the interventricular septum and delivers blood to portions of the left and right ventricle.

• Right coronary
• Circumflex
• Left anterior descending
• Cardiac
• Left anterior descending

When a staff member asks where venous blood from the coronary circulation drains into, what is the best response

by the nurse? The:

• Superior vena cava
• Inferior vena cava
• Right atrium
• Reft atrium
• Right atrium

While viewing the electrocardiogram, the nurse recalls the _____ conducts action potentials down the atrioventricular septum.

• Bachmann bundle
• Bundle of His
• Sinoatrial node
• Atrioventricular node
• Bundle of His

A 13-year-old female took a weight loss drug that activated the sympathetic nervous system. Which of the following assessment findings would the nurse expect?

• Decreased myocardial contraction
• Decreased heart rate
• Increased cardiac conduction
• Increased intranodal conduction time
• Increased cardiac conduction

A 50-year-old female received trauma to the chest that caused severe impairment of the primary pacemaker cells of the heart. Which of the following areas received the greatest damage?

• Atrioventricular (AV) node
• Sinoatrial (SA) node
• Bundle of His
• Ventricles
• Sinoatrial (SA) node

A nurse assesses the heart after acetylcholine because the effect of acetylcholine on the heart is to

• Decrease the refractory period
• Increase calcium influx
• Increase the strength of myocardial contraction
• Decrease the heart rate
• Decrease the heart rate

A nurse is discussing the pressure generated at the end of diastole. Which term is the nurse describing?

• Preload
• Afterload
• Systemic vascular resistance
• Total peripheral resistance
• Preload

Which principle should the nurse remember when planning nursing care for a patient with heart problems?As stated by the Frank-Starling law, there is a direct relationship between the _____ of the blood in the heart at the end of diastole and the _____ of contraction during the next systole.

• Pressure, duration
• Volume, force
• Viscosity, force
• Viscosity, duration
• Volume, force

Within a normal physiologic range, an increase in left ventricular end-diastolic volume would lead the nurse to

monitor for:

• An increased force of contraction
• A decrease in cardiac output
• An increase in heart rate
• Heart failure
• An increased force of contraction

While planning care for a heart patient, which principle should the nurse recall? Right ventricular afterload is

affected by:

• Vascular resistance in the systemic vessels
• Right end-diastolic pressure
• Pressures in the vena cava
• Pulmonary vascular resistance
• Pulmonary vascular resistance

Which principle should the nurse remember while planning care for a cardiac patient? Pressure in the left ventricle must exceed pressure in the _____ before the left ventricle can eject blood.

• Coronary arteries
• Aorta
• Inferior vena cava
• Pulmonary veins
• Aorta

A 50-year-old female presents with a low heart rate and low blood pressure. She is given an intravenous (IV) infusion of fluids. The increase in atrial distension results

in:

• Renal retention of fluids
• Depressed myocardial contractility
• Release of acetylcholine
• Increased heart rate
• Increased heart rate

A nurse observes a cardiologist multiplying the heart rate by stroke volume. What is the cardiologist measuring?

• Vascular resistance
• Preload
• Cardiac output
• Ejection fraction
• Cardiac output

A patient researches baroreceptors online. Which information indicates a good understanding?

Baroreceptors are located in the:

• Renal artery
• Superior vena cava
• Carotid sinus
• Circle of Willis
• Carotid sinus
