WGU D236 PATHOPHYSIOLOGY OA REAL EXAM 400 + QUESTIONS AND DETAILED ANSWERS 20 23-2024 UPDATE ALREADY A GRADED Compare and contrast Type I and Type II Diabetes - correct answer Type I diabetes is caused by lack of insulin. With out insulin signaling, glucose will not be taken into the cell and leads to high blood glucose (hyperglycemia). Type I is usually treated with insulin injections. Type II diabetes is caused by a desensitization to insulin signaling. The insulin receptors are no longer responding to insulin, which also leads to hyperglycemia. Type II is u sually treated with drugs to increase the sensitization to insulin (metformin), dietary and life -style changes or insulin injections. Describe some reasons for a patient needing dialysis - correct answer AEIOU -acidosis. Electrolytes, Intoxication/Ingest ion, overload, uremia. Patients with kidney or heart failure. A build up of phosphates, urea and magnesium are removed from the blood using a semi -permeable membrane and dialysate. AEIOU: A—acidosis; E—electrolytes principally hyperkalemia; I—ingestions or overdose of medications/drugs; O—overload of fluid causing heart failure; U—uremia leading to encephalitis/pericarditis Compare and contrast hemodialysis and peritoneal dialysis. What are some reasons for a patient choosing one over th e other? - correct answer Hemodialysis uses a machine to pump blood from the body in one tube while dialysate (made of water, electrolytes and salts) is pumped in the separate tube in the opposite direction. Waste from the blood diffuses through the semi permeable membrane separating the blood from the dialysate. Peritoneal Dialysis does not use a machine, but instead injects a solution of water and glucose into the abdominal cavity. The peritoneum acts as the membrane instead of dialysis tubing. The was te products diffuse into the abdominal cavity and the waste solution is then drained from the body. Peritoneal dialysis offers continuous filtration and is less disruption to the patient's daily routines. However, it does require some training of the patient and is not recommended for individuals who are overweight or have severe kidney failure. Hemodialysis provides medical care, but 3 times a week for several hours sitting at a hospital or clinic. Individuals with acute kidney failure are recommended to use hemodialysis. How does homeostasis and maintaining optimal physiological health impact your wellbeing? - correct answer Homeostasis acts to create a constant and stable environment in the body despite internal and external changes. Proteins and o ther cellular processes require optimal conditions in order to carry out their functions. Alterations in pH, salt concentration, temperature, glucose levels, etc. can have negative effects on health, so it is vital for mechanisms that regulate homeostasi s to function properly for maintaining good health Differentiate between Innate Immunity and Adaptive Immunity ? - correct answer The innate immune system encompasses physical barriers and chemical and cellular defenses. Physical barriers protect the bo dy from invasion. These include things like the skin and eyelashes. Chemical barriers are defense mechanisms that can destroy harmful agent. Examples include tears, mucous, and stomach acid. Cellular defenses of the innate immune response are non -specifi c. These cellular defenses identify pathogens and substances that are potentially dangerous and takes steps to neutralize or destroy them. Adaptive immunity is an organism's acquired immunity to a specific pathogen. As such, it's also referred to as acqu ired immunity. Adaptive immunity is not immediate, nor does it always last throughout an organism's entire lifespan, although it can.The benefits of buying summaries with Stuvia:
