Vital signs :
T= 97.6 F (36.4C), BP 140/70, P 93, R 22.
complete blood count (CBC), basic metabolic panel (BMP), brain natriuretic peptide (B-type natriuretic peptide assay or BNP), troponin, creatine kinase (CPK), creatine kinase-MB (CKMB), and albumin. The APN also prescribes oral (PO) Furosemide and arranges an outpatient electrocardiogram (ECG, EKG), chest X-ray, and echocardiogram.
1. Which assessment findings during this visit are consistent with heart failure?
2. Why did the APN about back pain, stomach pain, confusion, dizziness or a feeling that she might faint?
3. Explain what the following terms indicate and include the normal values: cardiac output, stroke volume, afterload, preload, ejection fraction and central venous pressure. Is an ejection fraction of 55% significant. Provide rationale.
5. Discuss the body’s compensatory mechanisms during hear failure. Include an explanation of the Frank-Starling law in your discussion.
6. Heart failure can be classified as left or right ventricular failure, systolic versus diastolic, according to the New York Heart Association (NYHA) and using the ACC/AHA (American Heart Association) guidelines. Explain these four classification systems and the signs and symptoms that characterize each. Which Classification fits this patient?

8. What information will each of the following tests provide: CBC, BMP, BNP, Troponin, CPK, CKMB, and albumin, EKG, CXR, and Echocardiogram
