A patient with heart failure is prescribed an angiotensin-converting enzyme inhibitor. What should the nurse explain as being the purpose of this medication? 1) Reduce afterload 2) Decrease preload 3) Increase contractility 4) Control sympathetic nervous system response to decreased cardiac output

ANS: 1 Angiotensin-converting enzyme inhibitors (ACE-Is) are usually the first line of medications used to reduce afterload.

The nurse is concerned that a patient with heart failure is decompensating. What assessment finding supports the nurse's clinical decision? 1) Dyspnea on exertion 2) Dry persistent cough 3) Weak peripheral pulses 4) Increased urine output

ANS: 1 Dyspnea on exertion indicates deceased cardiac output and worsening heart failure.

The nurse explains about the development of tissue clumps within the innermost layer of the heart to a patient with infective endocarditis. What aspect of the disease process is the nurse describing? 1) Vegetation 2) Oxidation 3) Foam cells 4) Fatty streaks

ANS: 1 Infective endocarditis begins with damage to the endocardial lining of the heart, which leads to the development of nonbacterial thrombotic endocardial lesion. If the patient is exposed to microorganisms present in the bloodstream, they can become trapped under the layers of platelet and fibrin deposits. These clumps of tissue are known as vegetation.

After completing a physical assessment the nurse anticipates the health-care provider to prescribe diagnostic testing for valvular disease. What did the nurse assess to come to this conclusion? 1) Heart murmur 2) Carotid artery bruit 3) Bounding peripheral pulses 4) Displaced point of maximum impulse

ANS: 1 Often the first clinical sign of valvular disease is the auscultation of a murmur.

The nurse notes that a newly admitted patient has an elevated sedimentation rate. For which health problem should the nurse plan care for this patient? 1) Pericarditis 2) Heart failure 3) Pericardial effusion 4) Coronary artery disease

ANS: 1 Positive inflammatory markers such as sedimentation rates may indicate the presence of pericarditis.

The nurse is concerned that a patient is at risk for developing infective endocarditis. What information in the patient's history caused the nurse to have this concern? 1) 70 years of age 2) Treatment for osteoarthritis 3) Sister being treated for chronic renal failure 4) Diagnosed with benign prostatic hyperplasia

If the fluid causing a pericardial effusion is not addressed, it can increase and cause cardiac tamponade. Pulsus paradoxus may occur. 3. If the fluid causing a pericardial effusion is not addressed, it can increase and cause cardiac tamponade, which is manifested by muffled heart sounds. 4. If the fluid causing a pericardial effusion is not addressed, it can increase and cause cardiac tamponade, which is manifested by jugular vein distention.

The nurse notes that a patient with heart failure has a normal ejection fraction. What should this information indicate to the nurse? Select all that apply. 1) It is a common diagnosis 2) It is associated with older patients with obesity 3) It is seen in patients with diabetes mellitus and atrial fibrillation 4) It is exacerbated with invasive procedures and dental examinations 5) There is less blood in the ventricle to eject because of the impaired filling
