Type I: Allergic Reaction What happens with subsequent cross-linking of mast-cell-bound IgE molecules by antigen

On subsequent exposure to the allergen, the IgE molecules located on the sensitized cells induce immediate degranulation of Mast cells. This causes the release of inflammatory mediators such as histamine, leukotrienes, and prostaglandins that results in vasodilation, bronchial smooth muscle contraction, and mucus production.

It can be heart at the upper RSB and radiates to the carotid arteries in the neck

Type 3 hypersensitivity reaction 1. Explain this reaction 2. How does this differ from type 2 reactions

1. These are immune-complex mediated where the Ag-Ab complex becomes soluble in the blood and then are deposited in areas of tissue (joints/kidneys) 2. The primary difference between type II and type III mechanisms is that in type II hypersensitivity antibody binds to the antigen on the cell surface, whereas in type III the antibody binds to a soluble antigen that was released into the blood or body fluids, and the complex is then deposited in the tissues

Explain the pathophys of R sided HF 1. High pulmonary vascular pressure (increased afterload) will cause an increased right ventricular contraction force in order to eject the blood. Overtime, this will 2. This will increase the amount of blood remaining in the right ventricle and, as a result, increase right ventricular preload, resulting 3. This will increase the amount of blood remaining in the right atrium and, therefore, increase right atrial preload. This causes

1. reduce the ejection fraction and the right ventricle will be unable to eject the normal amount of blood. 2. in the inability for the right atrium to eject the normal amount of blood into the right ventricle. 3. the back-up of blood volume and pressure in the vena cava and systemic veins. Jugular vein distension is characteristic of right heart failure.

The pathophys of Left sided HF: 1. High systemic vascular resistance, or increased afterload, will increase the left ventricular contraction force in order to eject the blood from the left ventricle. Over time, this will 2. As a result, left ventricular preload will be increased, impeding

1. reduce the patient's ejection fraction and the left ventricle will be unable to eject normal a normal amount of blood. This results in an increased amount of blood remaining in the left ventricle. 2. the left atrium from ejecting the normal amount of blood into the left ventricle. This will eventually cause blood to back up into the pulmonary veins.

The pathophys of Left sided HF: 3. Pressure will also be increased in the pulmonary veins. This increased pressure will force fluid from the pulmonary capillaries 4. If left ventricular heart failure is unresolved,

3. into the pulmonary tissues, which essentially floods those areas. The result is pulmonary edema and dyspnea. 4. volume and pressure will continue to build until it reaches the right side of the heart, contributing to right heart failure as well. In this case, this becomes a biventricular heart failure

Explain the pathophys behind individuals developing iron overload and becoming asplenic by adulthood

This is a type of hemolytic anemia and presents with the classic anemia signs and symptoms in addition to other serious complications. The lysis of large amounts of RBCs put the individual at risk for circulatory iron-overload The abnormal RBCs also occlude cerebral, splenic and glomerular blood vessels and create a high risk for strokes, splenic and kidney damage. Damage to the spleen is especially prevalent. Therefore, many sickle-cell individuals are asplenic by adulthood.

Type II hypersensitivity reaction Receptor blockage (explain this process)

This mechanism does not destroy the cell but rather causes cellular malfunction The antibody binds to the target cell and occupies receptors that would normally bind with other molecules required for normal cell function An example of receptor blockage is hyperthyroidism caused by Graves disease

Type 3 hypersensitivity reaction The size of the immune complexes determines the disease-causing potential. Explain

Very large immune complexes are cleared rapidly from the circulation by tissue macrophages. Very small immune complexes are filtered from the blood at the kidneys. The intermediate-sized complexes are deposited in certain target tissues, where they have severe pathologic consequences. a. glomerulonephritis (kidney) b. vasculitis (vessels) c. arthritis (degenerative joint disease)

Symptoms common to both intrinsic and extrinsic asthma include: Dizziness. Slowed breathing. Wheezing. Elevated heart rate.

Wheezing.

Symptoms common to both intrinsic and extrinsic asthma include: Wheezing. Slowed breathing. Dizziness. Elevated heart rate.

Wheezing.

Unlike emphysema, as discussed above, there is normal amount of elastin. So, the issue is not related to recoil in the restricted lung. The issue is with compliance, which is decreased in a restrictive disorder. Using pulmonary fibrosis as an example, fibrous or scarred tissue increases the elasticity of the lung, but compliance decreases due to the scarring caused by the fibrosis which prevents the lungs from expanding.

With low compliance, the lungs do not ventilate adequately because there is limited air that is able to enter the lung on inhalation. If there is not sufficient air going in, then there cannot be sufficient air going out. Therefore, the FVC will be lower while FEV1 increases.

Furthermore, the reduction in RBC level will decrease blood volume, activating the renin-angiotensin-aldosterone (RAA) system, which will result in what?

fluid retention and movement of interstitial fluid into the capillaries. This will not only increase plasma volume, but also dilute the plasma further. The dilute blood flows faster, which creates a hyperdynamic state. This "stresses" the cardiac system and can result in tachycardia or even heart failure.

PFTs alone cannot differentiate among the causes of respiratory abnormalities what can they help dx

he PFT can help the NP determine the patient's respiratory pattern, specifically if the abnormality is due to an obstructive or restrictive problem. Once the pattern is identified, PFTs allow the NP to determine the severity of the disease.

The pathophys behind Macrocytic anemias can be explained by: Folate and cobalamin (vitamin B12) are required for red blood cell DNA synthesis; therefore, a deficiency in either results in

impaired DNA replication of the RBC. This causes the erythroblasts to continue to increase in size (macrocytic) instead of undergoing cell division.

Factors causing L sided HF: Disease processes that increase left ventricular afterload

include hypertension and aortic valve disorders.

The pathophysiology of IDA is very simple: Explain

insufficient Fe levels or inability for mitochondria to utilize Fe effectively leads to decreased Hb synthesis and the formation of smaller, paler cells.

manifested by vomiting, diarrhea, or abdominal pain.

Iron Deficiency Anemia Iron deficiency is categorized as a

microcytic and hypochromic anemia. Iron deficiency anemia (IDA) is the most common type of anemia, Causes of IDA include: Inadequate dietary intake. Chronic and or occult bleeding: hemorrhage, colitis, cirrhosis, GI ulcers, esophageal lesions, or menorrhagia; note that it only takes 2-4 mL (about 1 tsp) of blood loss per day to lose 1-2 mg of iron). Decreased ability to utilize Fe for heme synthesis (e.g. transferrin deficiencies and mitochondrial defects). These are a less common cause of IDA.

The thalassemia(s) are a group of related inherited autosomal recessive genetic disorders. Similar to sickle cell anemia, the affected individual However, unlike sickle cell anemia

Blood Loss Anemia This involves situations where the number of RBCs lost is greater

than number of RBCs produced due as the direct result of blood loss is considered blood loss anemia. Blood loss anemia can be acute or chronic.

The pathophysiology of sickle cell anemia involves a single amino acid change on the beta-chain which results in

the formation of elongated, "sickled" Hb molecules (designated HbS) which does not bind oxygen as readily. The sickling of millions of hemoglobin molecules causes distortion of RBCs that house those molecules. This weakens the RBCs and they rupture after only 10-15 days in circulation.

Right side HF is defined as

the inability of the right ventricle to provide adequate blood flow into the pulmonary circulation.

Type II hypersensitivity reaction Neutrophil-mediated damage (explain this process)

Antibody activates complement increasinging C3a and C5a (chemotactic for neutrophils) Binding of neutrophil via Fc/C3b receptors releases granules onto healthy tissue. Degranulation substances and toxic O2 products damage tissue Because the tissue is large, phagocytosis cannot be completed

It is the endothelium, under normal functioning that maintains balance between the vasoconstrictive and vasodilation actions, prevents platelets from aggregating and control of the production of fibrin. Explain the pathophys of atherosclerosis:

Atherosclerosis begins with damage to the endothelium. When the endothelium becomes damaged, our familiar inflammatory processes occur. Macrophages attach to the endothelium, setting up phagocytosis; plaque formation and vasoconstriction also occurs marking the beginning of atherosclerosis. The plaque lesions located in the vessels become enlarged which allows the plaque to progress within the enlarged vessel lumen. The plaque lesion disrupts normal blood flow and causes thrombus formation

Cancer cells are defined by 2 heritable properties.

Autonomy a. The cancer cell has independence from normal cellular controls. Meaning they disregard normal limitations of growth. The majority of malignant cells commonly produce telomerase (enzyme that repairs the telomeres) so the cell becomes immortal Anaplasia a. Anaplasia is the loss of cell differentiation.
