Weight gain
A client with a history of acute coronary syndrome asks why she needs to take aspirin 81 mg every day. The most appropriate response by the nurse would be:
"Aspirin will help prevent blood clotting."
Knowing the high incidence and prevalence of heart failure among older adults, the manager of a long-term care home has organized a workshop on the identification of early signs and symptoms of heart failure. Which teaching point is most accurate?
"Displays of aggression, confusion, and restlessness when the resident has no history of such behavior can be a sign of heart failure."
A client with heart failure asks, "Why am I taking a 'water pill' when it's my heart that is having a problem?" While educating the client about the Frank-Starling mechanism, which explanation is most appropriate to share?
"Since your heart is not pumping efficiently, the kidneys are getting less blood flow; therefore, the kidneys are holding on to sodium and water."

Which statement regarding heart failure is true?
In compensated heart failure, an increase of end-diastolic volume causes increased force of left ventricular contraction.
An 86-year-old client is disappointed to learn that he or she has class II heart failure despite a lifelong commitment to exercise and healthy eating. Which age-related change predisposes older adults to the development of heart failure?
Increased vascular stiffness
A client has just been told that he has an infection of the inner surface of the heart. He is also told that the bacteria has invaded his heart valves. What term is used for this disease process?
Infective endocarditis
What is the most common cause of acute percarditis?
viral infections
Exudate in the pericardial cavity is a characteristic of which cardiac condition?
Pericardial effusion
A client is seen in the emergency room reporting sharp chest pain that started abruptly. He says it has radiated to his neck and abdomen. He also states that it is worse when he takes a deep breath or swallows. He tells the nurse that when he sits up and leans forward the pain is better. Upon examination the nurse notes a pericardial friction rub and some EKG changes. Which disease should the nurse suspect this client to have?
Pericarditis
A client is at high risk for the development of rheumatic heart disease. The most important information for the nurse to provide would be:
Prompt diagnosis and treatment of streptococcal infections
A teenager is seen in the emergency room with reports of a sore throat, headache, fever, abdominal pain, and swollen glands. His mother tells the nurse that he was seen 3 weeks before in the clinic and treated with antibiotics for strep throat. He was better for a few days but now he seems to have gotten worse in the last 2 days. What should the nurse suspect is wrong with this client?
Rheumatic fever
ST segment elevation is only present in what?
STEMI
The nurse should anticipate administering intravenous antibiotic therapy as a priority to a client experiencing which type of shock?
Septic shock
Unstable angina (UA)/non-ST-segment elevation myocardial infarction (NSTEMI) is a clinical syndrome that ranges in severity between stable angina and MI. It is classified according to its risk of causing an acute MI and is diagnosed based on what assessment data? Select all that apply.
Serum biomarkers ECG pattern
What is the primary cause of heart failure in infants and children?
Structural heart defects
A 60-year-old woman has just been diagnosed with heart failure and her primary care provider is describing the concept of adaptation. Which compensatory mechanisms may have masked the client's heart failure? Select all that apply.
Sympathetic nervous stimulation Hypertrophy of the myocardium Increased renin-angiotensin-aldosterone system (RAAS) function Increased preload
