74-year-old woman is admitted to the hospital with heart failure. She had been growing progressively weaker and had ankle edema, dyspnea on exertion, and three-pillow orthopnea. On admission, she is severely dyspneic and can answer questions only with one-word phrases. She is diaphoretic, with a heart rate of 132 beats/min, and blood pressure 98/70 mm Hg. She is extremely anxious.…
A. Ions in the body break up into positive and negative ions and form a solution called an electrolyte. Dr.Kim was worried about Eugene’s electrolytes in regard to his heart and brain because they control nerve and muscle impulses.…

Three types of homeostasis are involved: fluid balance, electrolyte balance, and acid-base balance. Fluid balance means that the total quantity of body water remains almost constant and that the distribution between the ICF and ECF are normal. Electrolyte balance implies the same thing for ions. Acid-base balance means that the pH of the ECF is maintained in the range of 7.35 to 7.45, and that gains or losses of hydrogen ion as a consequence of metabolism are followed by equivalent losses or gains so as to maintain constant buffer reserves.…
People with renal failure and are in the process of dialysis have been known to have several homeostatic imbalances. One of the major effects is electrolyte imbalance and this usually lead to different types of conditions. One of these condition known as hyperkalemia may occur if calcium levels exceed the amount that can be excreted. Another condition that may arise in the course of dialysis is arrhythmias (Elsevier,2013). This can lead to electrolyte imbalance and changes in homeostasis of acid and base. Other issues that can arise related to increased removal of fluid volumes include low blood pressure, cramping as well as muscle spasms. During dialysis, there is a high posibility of damage to the normal net filtration pressure due to increased membrane permeability and this as well leads to homeostatic imbalance.…
I’ve worked in a cardiac unit for the past three years and have been trained in identifying the various rhythms that the heart can have. In my training, I have learned that there are chemical reasons why the heart will behave in certain ways. The body needs to have a balance of electrolytes (substances that can conduct electricity) to function properly. This is especially important in the heart. Sodium is needed for the generation of electrical signals vital for movement. The heartbeat is generated through electrical impulses that tell the muscle to contract and relax. People that are in heart failure (and are often recipients of ICD’s) sometimes will get what is called fluid overloaded. That fluid overload can happen when sodium levels become too low and fluid accumulates in the limbs, around the lungs and even the heart because the heart is pumping…
I. Description: Congestive Heart Failure is more of a syndrome than a disease. Heart failure may be classified according to the side of the heart affected, (left- or right-sided failure), or by the cardiac cycle involved, (systolic or diastolic dysfunction). (Schilling-McCann p. 176). The word "failure" refers to the heart's inability to pump enough blood to meet the body's metabolic needs. (Schilling-McCann p. 176). When the heart fails to deliver adequate blood supply edema may develop. (Cadwallader p. 1141). Where edema occurs depends on what side of the heart is failing.…
No such therapies have been discovered for diastolic heart failure; however, angiotensin receptive blocking agents have the potential to decrease morbidity in the patients, but not the mortality. (Chatterjee 574). Although patients with diastolic heart failure have a lower annual mortality rate than patients with systolic heart failure, they have a higher rate than the general population. (Chatterjee 574). They also have hospitalization rates similar to those of patients with systolic heart failure. These observations emphasize diastolic heart failure as an important contributor to morbidity, mortality, and health care costs, and highlight the need for further research and clinical trials examining this condition. (Chatterjee 572). Differentiating between systolic and diastolic dysfunction is essential because their long-term treatments are. The treatments of choice in patients with systolic dysfunction are ACE inhibitors, digoxin, diuretics and beta blockers. In patients with diastolic dysfunction, the cornerstones of treatment depend on the underlying cause. (Chatterjee…
Patients with renal failure experience a lot of imbalances while receiving dialysis. Electrolyte imbalances are the most common, usually presenting with hyperkalemia. This happens when the amount of calcium is more than the kidneys can excrete. Arrhythmias may also occur during dialysis. It too causes an imbalance of electrolytes or changes in acid-base homeostasis. Severe cramping, muscle spasms, and low blood pressure are some complications experienced from dialysis. This happens because of the removal of increased volume of fluids. Net filtration pressure is damaged as a result of increased permeability of the membrane. This too causes a homeostatic imbalance. Urinary incontinence and retention, thrombosis, and sleeping problems may all occur from the use of dialysis. (Steadyheatlh, 2004)…
Congestive heart failure is a very common disease. While many other forms of heart disease have become less common, heart failure has been increasing. Congestive heart failure has become the most common diagnosis in the hospital for patients over 65 years of age. Diastolic heart failure accounts for up to 40% of patients with congestive heart failure and is associated with a better prognosis as compared to patient with systolic dysfunction (Arora, Krummerman, Vijayaraman, Rosengarten, Suryadevara, Lejemtel, and Ferrick, 2005). Congestive heart failure occurs when the flow of…
As heart failure develops in the body nueurohormaonal mechanisms stimulate. Epinephrine and Norepinephrine are released by the sympathetic nervous system. After the heart begins to have a decrease in renal perfusion there is a release in renin then the formation of angiotensin I. This is then converted into angiotensin II which makes the blood vessels constrict and activated the release of…
Medical treatment of Congestive Heart Failure includes but is not limited to: improving the heart’s function; removal of fluid in the peritoneal and thoracic cavities; decreasing cardiac demands; increasing tissue perfusion; and treating anaphylaxis. The primary focus is treating any underlying causes of signs and symptoms associated with…
