Chapter 19: Heart and Neck Vessels
1. The sac that surrounds and protects the heart is called the:
a. Pericardium.
b. Myocardium.
c. Endocardium.
d. Pleural space.
2. The direction of blood flow through the heart is best described by which of these?
a. Vena cava right atrium right ventricle lungs pulmonary artery left atrium left ventricle
b. Right atrium right ventricle pulmonary artery lungs pulmonary vein left atrium left ventricle
c. Aorta right atrium right ventricle lungs pulmonary vein left atrium left ventricle vena cava
d. Right atrium right ventricle pulmonary vein lungs pulmonary artery left atrium left ventricle
3. The nurse is reviewing the anatomy and physiologic functioning of the heart. Which
statement best describes what is meant by atrial kick?
a. The atria contract during systole and attempt to push against closed valves.
b. Contraction of the atria at the beginning of diastole can be felt as a palpitation.
c. Atrial kick is the pressure exerted against the atria as the ventricles contract during systole.
d. The atria contract toward the end of diastole and push the remaining blood into the ventricles.
4. When listening to heart sounds, the nurse knows the valve closures that can be heard best
at the base of the heart are:
a. Mitral and tricuspid.
b. Tricuspid and aortic.
c. Aortic and pulmonic.
d. Mitral and pulmonic.
5. Which of these statements describes the closure of the valves in a normal cardiac cycle?
a. The aortic valve closes slightly before the tricuspid valve.
b. The pulmonic valve closes slightly before the aortic valve.
c. The tricuspid valve closes slightly later than the mitral valve.
d. Both the tricuspid and pulmonic valves close at the same time.

a. Atrioventricular (AV) node.
b. Sinoatrial (SA) node.
c. Bundle of His.
d. Bundle branches.
7. The electrical stimulus of the cardiac cycle follows which sequence?
a. AV node SA node bundle of His
b. Bundle of His AV node SA node
c. SA node AV node bundle of His bundle branches * correct answer!
d. AV node SA node bundle of His bundle branches- bank answer- IS WRONG!
, 8. The findings from an assessment of a 70-year-old patient with swelling in his ankles
include jugular venous pulsations 5 cm above the sternal angle when the head of his bed is
elevated 45 degrees. The nurse knows that this finding indicates:
a. Decreased fluid volume.
b. Increased cardiac output.
c. Narrowing of jugular veins.
d. Elevated pressure related to heart failure.
9. When assessing a newborn infant who is 5 minutes old, the nurse knows which of
these statements to be true?
a. The left ventricle is larger and weighs more than the right ventricle.
b. The circulation of a newborn is identical to that of an adult.
c. Blood can flow into the left side of the heart through an opening in the atrial septum.
d. The foramen ovale closes just minutes before birth, and the ductus arteriosus closes
immediately after.
10. A 25-year-old woman in her fifth month of pregnancy has a blood pressure of 100/70 mm
Hg. In reviewing her previous examination, the nurse notes that her blood pressure in her second
month was 124/80 mm Hg. In evaluating this change, what does the nurse know to be true?
a. This decline in blood pressure is the result of peripheral vasodilatation and is an
expected change.
b. Because of increased cardiac output, the blood pressure should be higher at this time.
c. This change in blood pressure is not an expected finding because it means a decrease in
cardiac output.
d. This decline in blood pressure means a decrease in circulating blood volume, which is
dangerous for the fetus.
11. In assessing a 70-year-old man, the nurse finds the following: blood pressure 140/100 mm
Hg; heart rate 104 beats per minute and slightly irregular; and the split S2 heart sound. Which
of these findings can be explained by expected hemodynamic changes related to age?
a. Increase in resting heart rate
b. Increase in systolic blood pressure
c. Decrease in diastolic blood pressure
d. Increase in diastolic blood pressure
12. A 45-year-old man is in the clinic for a routine physical examination. During the recording of
his health history, the patient states that he has been having difficulty sleeping. I'll be sleeping
great, and then I wake up and feel like I cant get my breath. The nurse's best response to this
would be:
a. When was your last electrocardiogram?
b. It's probably because its been so hot at night.
c. Do you have any history of problems with your heart?
d. Have you had a recent sinus infection or upper respiratory infection?
13. In assessing a patient's major risk factors for heart disease, which would the nurse want

b. Personality type, high cholesterol, diabetes, and smoking
c. Smoking, hypertension, obesity, diabetes, and high cholesterol
d. Alcohol consumption, obesity, diabetes, stress, and high cholesterol
