Question 1

A client presents with chest pain that has not been relieved by nitroglycerin medication. A review of the client's medical record shows that the client has type 2 diabetes. The blood pressure of the client is 150/90 mm Hg. Which condition has the client developed?

Accepted Answer

Chest pain that is not relieved by nitroglycerin medication and is accompanied by a history of type 2 diabetes and elevated blood pressure (as seen with a reading of 150/90 mm Hg) is indicative of a myocardial infarction (heart attack). Angina may also present with chest pain, but it is typically relieved by nitroglycerin medication. Pericarditis and myocarditis may also cause chest pain, but they are not typically associated with a history of type 2 diabetes and elevated blood pressure.

Question 2

A client visits the hospital with chest pain, and the vital signs are 101.5°F body temperature and 125/85 mm HG blood pressure. The echocardiogram of the client shows valve perforation, and a new regurgitant murmur is heard through the stethoscope on examination. Which condition has the client developed?

Accepted Answer

The symptoms and findings in the client suggest infective endocarditis, which is an infection of the heart valves. Chest pain, fever, and new regurgitant murmurs are common in this condition. The presence of valve perforation on echocardiogram also supports this diagnosis. Myocarditis and pericarditis may present with similar symptoms, but they are less likely to cause valve perforation and regurgitant murmurs. Therefore, option A is the best choice.

Question 3

A registered nurse is teaching a student nurse about infective endocarditis. Which statements made by the student nurse about the complication of the condition indicates effective learning?

Accepted Answer

All of the choices A, B, and C are possible complications of infective endocarditis. The infection can cause damage to the heart valves, leading to regurgitation and heart failure. Additionally, abscesses can form within the heart tissue, which can impair cardiac function and lead to systemic infection. Therefore, the student nurse's understanding of these potential complications indicates effective learning.

Question 4

Which condition is characterized by the deposition of immune complexes, causing inflammation and fluid accumulation in the pericardial sac?

Accepted Answer

This condition is known as Dressler's syndrome, which is characterized by the deposition of immune complexes in the pericardium, causing inflammation and fluid accumulation. Myocarditis is inflammation of the heart muscle, typically caused by a viral infection or autoimmune disease. Infective endocarditis is an infection of the heart valves and inner lining of the heart, usually caused by bacteria. Unstable angina is a type of chest pain that occurs at rest or with minimal exertion, and may indicate an impending heart attack.

Question 5

A client reports myalgia and fever. On physical examination, an S₃ gallop rhythm was heard through the stethoscope. Which finding confirms that the client has developed myocarditis?

Accepted Answer

The answer of A client reports myalgia and fever. On...

Question 6

A client has frequent premature ventricular contractions. Which factor should be the priority assessment by the nurse?

Accepted Answer

Premature ventricular contractions can affect blood pressure and oxygen saturation, potentially leading to cardiovascular compromise. Therefore, monitoring these vital signs is the priority assessment for the nurse. Sensations of palpitation and causative factors can also be assessed, but they are not as urgent as monitoring the client's vital signs.

Question 7

A nurse is providing discharge instructions to a client who is being discharged after treatment for myocardial infarction. Which statement made by the client indicates effective learning?

Accepted Answer

Planning periods of rest in the morning and evening is an effective way to manage fatigue and promote rest after a myocardial infarction. Option A is incorrect as it suggests that the client is exercising too soon after eating, which can be detrimental to their health. Option B is incorrect as weight gain is typically an undesirable outcome after treatment for myocardial infarction.

Question 8

Which is the outer layer of the heart?

Accepted Answer

The outer layer of the heart is the pericardium, a tough sac that encloses the heart and helps to protect it. The myocardium is the middle layer of the heart, and it is made up of muscle tissue. The endocardium is the innermost layer of the heart, and it lines the chambers and valves.

Question 9

Which is the last region in the conduction of the cardiac conduction sequence?

Accepted Answer

The Purkinje fibers are the last region in the cardiac conduction sequence, responsible for spreading the electrical signal rapidly throughout the ventricles and causing them to contract in a coordinated manner. The sequence starts with the sinoatrial node, which generates the initial electrical impulse, followed by the atrioventricular node, which delays the signal slightly to ensure proper filling of the ventricles. The Bundle of His is a specialized group of conduction cells that transmits the signal from the atria to the ventricles.

Question 10

Which heart condition increases the demand for myocardial oxygen?

Accepted Answer

None of the options listed (A, B, C) directly increase the demand for myocardial oxygen. Factors that typically increase myocardial oxygen demand include increased heart rate, increased myocardial contractility, and increased wall stress (not specifically listed in the options provided).

Question 11

A 65-year-old female client presents with complaints of crushing pain on the left side of the chest. After examining the client, it is found that the client has unstable angina. Which intervention to reduce the pain is appropriate for the client?

Accepted Answer

Administering nitroglycerin is appropriate for reducing chest pain in a client with unstable angina. Changing positions or encouraging deep breaths may not relieve the pain caused by unstable angina.

Question 12

A nurse is reviewing a client's cardiac rhythm in an electrocardiogram and notes that the reading shows that the P wave and PR interval are absent. Which condition does the nurse interpret from this result?

Accepted Answer

The absence of P waves and PR interval suggests atrial fibrillation where there is disorganized electrical activity in the atria resulting in an irregular ventricular response. Ventricular fibrillation is characterized by irregular, erratic, and chaotic ventricular activity on an electrocardiogram. Premature ventricular contractions are characterized by early ventricular depolarization and a wide QRS complex on an electrocardiogram.

Question 13

A client whose neck vein has bulged presents with a sharp pain in the chest. The electrocardiogram shows an elevated ST segment, and the laboratory report shows an increase in the serum creatinine and blood urea nitrogen. Which condition has the client developed?

Accepted Answer

The combination of bulging neck vein, sharp chest pain, elevated ST segment on ECG, and increase in serum creatinine and BUN indicates pericarditis. The bulging neck vein is suggestive of increased central venous pressure, which can occur due to cardiac tamponade in pericarditis. The sharp chest pain is a common symptom in pericarditis. Elevated ST segment on ECG and increased serum creatinine and BUN are also associated with pericarditis. Myocarditis and infective endocarditis may present with elevated ST segment on ECG, but they are not associated with bulging neck vein or increased serum creatinine and BUN.

Question 14

A client presents with chest pain. The pain has not reduced, even after administering three nitroglycerine tablets within 10 minutes. Which diagnostic test should the primary health-care provider recommend to confirm that the client has developed myocardial infarction?

Accepted Answer

Cardiac troponin test is the most specific and sensitive test to diagnose myocardial infarction. It measures the levels of cardiac-specific troponin in the blood, which is released when there is damage to the heart muscle. Thallium stress test and intravascular angiosonography are not appropriate for the initial diagnosis of myocardial infarction. Electrocardiogram may show changes indicative of myocardial infarction, but it may not be conclusive, especially in the early stages.

Question 15

The nurse is caring for a client with angina pectoris. Which precautionary measures should the nurse advise the client to follow?

Accepted Answer

Patients with angina pectoris should consume a low-fat diet to prevent the buildup of plaque in the arteries. Exercise and high-fiber foods should also be encouraged, but the nurse should advise the client to consult with their physician before starting any exercise program or drastically changing their diet. Aspirin tablets, if prescribed by a physician, can actually be beneficial in preventing blood clots and further complications in patients with angina pectoris.

Question 16

A client complains of chest pain. On examination, a scratchy sound is heard through the stethoscope. Which intervention should be provided to the client?

Accepted Answer

The answer of A client complains of chest pain. On...

Question 17

A nurse is reviewing the results of a diagnostic test of a client who is being moved out of the intensive care unit. A cardiac troponin T level assay was performed while the client was in the intensive care unit, which indicated high levels of troponin. Which condition was the client diagnosed with?

Accepted Answer

High levels of cardiac troponin T are indicative of myocardial injury, which is a hallmark of acute myocardial infarction.

Question 18

A client presents with complaints of difficulty breathing and looks pale. The client experiences excessive perspiration and his or her electrocardiogram shows an irregular rhythm. Which other finding will indicate that the client may have developed myocardial infarction?

Accepted Answer

The fact that nitroglycerin did not relieve the pain, even after taking three doses, is a significant indicator that the client may have developed myocardial infarction. This is because nitroglycerin is commonly used to relieve the symptoms of angina, which has similar symptoms to myocardial infarction. If the medication is not effective in relieving the pain, it suggests a more serious condition. The other answer choices are not helpful in providing information about the presence of a myocardial infarction.

Question 19

A client presents with chest pain. Complete blood reports show an elevated level of white blood cells. Which clinical manifestation confirms that the client has myocarditis?

Accepted Answer

Myocarditis can present with various symptoms including dyspnea (difficulty breathing), arthralgia (joint pain), and even tonsillitis, as it is an inflammation of the heart muscle that can affect the body systemically. Elevated white blood cell count indicates an inflammatory or infectious process, which is consistent with myocarditis.

Question 20

A nurse is caring for a client with infective endocarditis. Which is the appropriate nursing intervention for this client?

Accepted Answer

Administering amphicillin is the appropriate nursing intervention for a client with infective endocarditis as it is a common antibiotic used to treat this condition. Nitroglycerin is used to treat angina, and urokinase is used to dissolve blood clots, neither of which are typically used in the treatment of infective endocarditis.
