The nurse is aware that the muscle layer of the heart, which is responsible for the heart's
contraction, is the:
a. endocardium.
b. pericardium.
c. mediastinum.
d. myocardium.
d. myocardium.

The myocardium is the specialized muscle layer that allows the heart to contract.
The nurse clarifies that the master pacemaker of the heart is the:
a. left ventricle.
b. atrioventricular (AV) node.
c. sinoatrial (SA) node.
d. bundle of His.
c. sinoatrial (SA) node.

The SA node is the master pacemaker of the heart.
The nurse is aware that the symptoms of an impending myocardial infarction (MI) differ in
women because acute chest pain is not present. Women are frequently misdiagnosed as
having:
a. hepatitis A.
b. indigestion.
c. urinary infection.
d. menopausal complications.
b. indigestion.

Indigestion, gallbladder attack, anxiety attack, and depression are frequent misdiagnoses for
women having an MI.
The nurse identifies the "LUBB" sound of the "LUBB/DUBB" of the cardiac cycle as the
sound of the:
a. AV valves closing.
b. closure of the semilunar valves.
c. contraction of the papillary muscles.
d. contraction of the ventricles.
a. AV valves closing

The LUBB is the first sound of a low pitch heard when the AV valves close..
A patient is admitted from the emergency department. The emergency department physician
notes the patient has a diagnosis of heart failure with a New York Heart Association (NYHA)
classification of IV. This indicates the patient's condition as:
a. moderate heart failure.
b. severe heart failure.
c. congestive heart failure.
d. negligible heart failure.
b. severe heart failure.

Class IV: Severe; patient unable to perform any physical activity without discomfort. Angina
or symptoms of cardiac inefficiency may develop at rest.
The nurse assesses that the home health patient has no signs or symptoms of heart failure, but
does have a history of rheumatic fever and has been recently diagnosed with diabetes mellitus.
The nurse is aware that using the American College of Cardiology and the American Heart
Association (ACC/AHA) staging, this patient would be a:
a. stage A.
b. stage B.
c. stage C.
d. stage D.
a. stage A.

The ACC/AHA staging describes stage A as a person without symptoms of heart failure, but
with primary conditions associated with the development of the disease.
The nurse caring for a patient recovering from a myocardial infarct who is on remote
telemetry recognizes the need for added instruction when the patient says:
a. "I can ambulate in the hallway with this gadget on."
b. "I always take off the telemetry device when I shower."
c. "My EKG is being watched by one of the nurses in CCU on the home unit."
d. "I am able to sleep just fine with this device on."
b. "I always take off the telemetry device when I shower."

Remote telemetry allows the patient to be on a separate unit, but be monitored in a central
location. The patients can be ambulatory and can sleep with the monitor on. They should not
remove the monitor to shower.
The nurse assesses pitting edema that can be depressed approximately an inch and refills in 15 seconds. The nurse would document this assessment as:
a. +1 edema.
b. +2 edema.
c. +3 edema.

A +2 edema can be documented if the skin can be depressed inch and respond within 15
seconds.
What do dark or "cold" spots on a thallium scan indicate?
a. Tissue with adequate blood supply
b. Dilated vessels
c. Areas of neoplastic growth
d. Tissue that has inadequate perfusion
d. Tissue that has inadequate perfusion

Thallium scans show adequate perfused areas by the collection of thallium. Dark spots or "cold spots" indicate tissues that have inadequate perfusion.

indication of:
a. normal heart action.
b. mild heart failure.
c. moderate heart failure.
d. severe heart failure.
c. moderate heart failure.

An ejection factor (cardiac output) of 42% indicates moderate heart failure.
The nurse takes into consideration that age-related changes can affect the peripheral circulation because of: a. sclerosed blood vessels. b. hypotension. c. inactivity. d. poor nutrition.a. sclerosed blood vessels. Aging causes sclerotic changes in the blood vessels that lead to decreased elasticity and narrowing of the vessel lumen.The nurse assessing a cardiac monitor notes that the cardiac complexes each have a P wave followed by a QRS and a T. The rate is 120. The nurse recognizes this arrhythmia as: a. sinus bradycardia. b. atrial fibrillation. c. sinus tachycardia. d. ventricular tachycardia.c. sinus tachycardia. Sinus tachycardia has a P wave followed by the QRS and the T. All the components of the complex are present and in the correct order, but the rate is over 100 beats a minute.After an influenza-like illness, the patient complains of chills and small petechiae in his mouth and his legs. A heart murmur is detectable. These are characteristic signs of: a. congestive heart failure. b. heart block. c. aortic stenosis. d. infective endocarditis.d. infective endocarditis. Collection of subjective data includes noting patient complaints of influenza-like symptoms with recurrent fever, undue fatigue, chest pain, and chills. Objective data may reveal the significant signs of petechiae in the conjunctiva and mouth. Both subjective data and objective data are indicative of infective endocarditis.The nurse notes a run of three ventricular contractions (PVC) that are not preceded by a P wave. This particular arrhythmia can progress into: a. atrial fibrillation and possible emboli. b. sinus tachycardia and syncope. c. ventricular tachycardia and death. d. sinus bradycardia and fatigue.c. ventricular tachycardia and death. PVCs are capable of progressing into ventricular tachycardia and death.The nurse reminds the patient who is on Coumadin for the treatment of atrial fibrillation that the ideal is to maintain the international normalized ratio (INR) at between: a. 1 and 2. b. 2 and 3. c. 3 and 4. d. 4 and 5.b. 2 and 3. The desired INR for the monitoring of anticoagulant therapy is between 2 and 3.What should a person with unstable angina avoid? a. Walking outside b. Eating red meat c. Swimming in warm pool d. Shoveling snowd. Shoveling snow The person with angina should avoid exposure to cold, heavy exercise, eating heavy meals, and emotional stress.The elderly patient with angina pectoris says she is unsure how she should take nitroglycerin when she has an attack. The nurse's most helpful response would be: a. "Continue to take nitroglycerin sublingually at 5-minute intervals until the pain is relieved." b. "If the pain is not relieved after three doses of nitroglycerin at 5-minute intervals, call your physician and come to the hospital." c. "When nitroglycerin is not relieving the pain, lie down and rest." d. "Use oxygen at home to relieve pain when nitroglycerin is not successful."b. "If the pain is not relieved after three doses of nitroglycerin at 5-minute intervals, call your physician and come to the hospital." Administer prescribed nitroglycerin. Repeat every 5 minutes, three times. If pain is unrelieved, notify the physician. Nitroglycerin administered sublingually usually relieves angina symptoms but does not relieve the pain from an MI. Administering nitroglycerin more than three times will probably not relieve the pain.The patient has been hospitalized for hypertensive episodes three times in the last months. While preparing the discharge teaching plan, the nurse assesses that he does not comply with his medication regimen. The nurse's immediate course of action would be to: a. reteach him about his medications. b. have a serious talk with him and his family about compliance. c. arrange for home visits after discharge. d. collect more information to identify his reasons for noncompliance.d. collect more information to identify his reasons for noncompliance.
