This disease is often found when a person is going to the doctor for a routine checkup; their labs usually show an increased amount of blood cells of all types. The patient’s hemoglobin the day of clinical was 8.8; his platelets were 641. Ultrasonography is a type of diagnostic tool used to screen for any type of tumors that may have precipitated the illness. The most common types that cause polycythemia are kidney and liver tumors. The kidneys produce erythropoietin; these are what generates…

chemical imbalance known as diabetic ketoacidosis (DIABETES.ORG). DKA causes osmotic diuresis which results in urinary losses of water and electrolytes (sodium and potassium). Potassium levels are initially elevated, however with insulin therapy, potassium shifts into cells and causes hypokalemia (ATI BOOK). Certain stressors and drugs can cause DKA include: acute infection, trauma, pancreatitis, stroke, corticosteroids, thiazide diuretics, and sympathomimetic. Signs and symptoms of DKA…

AKI is characterized by a sudden loss of function in the renal system. This disease can be 1. prerenal, meaning the issue lies somewhere before the kidneys (i.e. volume loss), a perfusion issue; 2. intrarenal, meaning the problem is within the kidneys (i.e. nephrotoxic agents); or 3. post-renal, meaning the kidneys have a problem with excreting urine. The kidneys can have atherosclerosis, an infection in the kidneys, inflammation…

in MRI scanning, similar to DWI is Perfusion weighted imaging (PWI). This technique can also be used to calculate the blood supply to a particular volume of the brain. The brain is rapidly scanned following the injection of a bolus, Gadolinium. The data obtained from these scans are then represented in a myriad of ways, including maps of regional cerebral blood volume and the mean transit times. Studies have shown, (Chen & Ni 2012) that in general, the perfusion defects identified with PWI are…

chronic pain, stroke, traumatic brain injury, autism, and schizophrenia and Parkinson's disease. During this time, I learned various research skills such as handling laboratory animals such as rats, running lab rat behavior shifts, histology, and perfusions. My histology duties include the training of any new histology members…

cancer most probably related to his profession of back hoe operator for 33 years which exposed him daily to the damaging UV light of the sun. The patient also has a history of MI that has led to a decrease in the efficiency of his heart and decreased perfusion leading to his chronic kidney disease due to damage to his glomeruli and the musculature of the heart. This also related to his diabetes mellitus which causes his neuropathy and damages his glomeruli of the kidneys decreasing filtration…

Faye was seen today following her PET scan and EBUS biopsy of her right upper lobe lesion. Unfortunately it has revealed a moderately differentiated adenocarcinoma and the PET san was positive in the area of the lesion. Reassuringly though there was no evidence of loco-regional lymph node spread or any evidence of distal metastases. This would normally suggest a stage 1 lung cancer but the complicating factor here is that the immunohistochemical staining has come back positive for an…

I looked down astonished at the beating heart before me. The surgeon attempted to clarify the procedure he was performing, but I was too busy trying to detect the clear string he was sewing in and out of the heart. I was in awe of his comfort with teaching an undergraduate student how to successfully execute a coronary artery bypass surgery, as if he knew I was interested in that specialty. He explained the condition of the patient and while I did not understand the terminology, I nodded with…

Medical Surgical Nursing II: Sickle Cell Anemia-Case Study The following case study is about sickle cell anemia. This disease process is more common in those of African-American decent and simplified means that a patient’s blood cells are abnormally shaped which causes different manifestations as well as complications. There is no cure for sickle cell anemia/disease, but it is treatable. A potential complication is acute kidney injury (AKI), as mentioned in this case study as well. AKI is a…

associated with both cooling and rewarming phase during the procedure. He further explained that sustained contraction of the uterine can exert blood flow through the intervillous space while the normal systemic blood flow is reduced. This abnormal perfusion will result in fetoplacental insufficiency and ultimately lead to the death of the fetus due to hypoxia. This fetal death is the most common in cardiopulmonary…
