Case Study 15 Scenario J.F. is a 50-year-old married homemaker with a genetic autoimmune defi ciency; she has suffered from recurrent bacterial endocarditis. The most recent episodes were a Staphylococcus aureus infection of the mitral valve 16 months ago and a Streptococcus mutans infection of the aortic valve 1 month ago. During this latter hospitalization, an ECG showed moderate aortic stenosis, moderate aortic insuffi - ciency, chronic valvular vegetations, and moderate left atrial enlargement. Two years ago J.F. received an 18-month course of parenteral nutrition (PN) for malnutrition caused by idiopathic, relentless nausea and vomiting (N/V). She has also had coronary artery disease (CAD) for several years, and 2 years ago…show more content…
However, it can also result from certain neurologic disorders — especially life-threatening increased intracranial pressure (ICP) — or from cardiovascular disorders that cause blood backflow into the heart with each contraction such as aortic insufficiency. Widened pulse pressure can easily be identified by monitoring arterial blood pressure and is commonly detected during routine sphygmomanometer recordings (Lippincott, 2005, pg 527-528). With acute aortic insufficiency, pulse pressure widens as the valve deteriorates. Signs and symptoms may include a bounding pulse, atrial and ventricular gallops, chest pain, palpitations, pallor, crackles, dyspnea, and jugular vein distention, may also be present. Tachycardia: Tachycardia typically refers to a heart rate that exceeds the normal range for a resting heart rate. When the heart beats rapidly, the heart pumps less efficiently and provides less blood flow to the body and the heart. The rapid heartbeat increases the workload and oxygen demand of the heart. Problems will occur with the heart as tachycardia persists over time. The heart is maintaining less oxygen, which will lead to an MI due to death of the myocardial cells. Patient will start to have angina because of this. Tachycardia is noted in many diseases and disorder like: fever endocarditis, anemia, HTN, pericarditis, abnormal heart impulses, anxiety, older age, sleep apnea, COPD, electrolyte imbalances, and many more. Tachycardia can be an
