WGU D236 Patho Study Guide [100% PASS] verified Pressure that is due to albumin in the bloodstream? *Ans* Oncotic Oncotic *Ans* a form of osmotic pressure exerted by proteins In the blood, _____ is the most common plasma protein and is, therefore, a primary determinant of oncotic pressure *Ans* albumin _____ controls osmotic pressure in vascular system, builds volume *Ans* Albumin One question was about the difference in children and adult immunity *Ans* Possible answer: naive T cells Learning check question: Which differences in immunity make children and older adult patients more susceptible to infections? Choose 2 answers Younger patients have fewer memory cells to combat infection Older adult patients have a dwindling population of naive T cells Older adult patients have more memory cells to combat infection Younger patients have a large population of naive T cells Older adult patients have a large population of naive T cells *Ans* Younger patients have fewer memory cells to combat infection Older adult patients have a dwindling population of naive T cells Rationale: younger patients have not been exposed to many pathogens, which means that they have fewer memory cells than adults. The primary immune response is relatively weak compared to a secondary response mediated by memory cells. Older adult patients do not have as many T cells compared to younger patients. When these patients encounter novel pathogens, the reduced number of naive T cells gives clonal selection fewer opportunities to "find" T cells that will be effective. Fluid and electrolyte levels are regulated by _______, which regulates actions such as thirst, ADH, the kidneys, and RAAS. *Ans* osmoreceptors Fluid deficit causes *Ans* -Excessive loss -Inadequate intake -Or combination of both Fluid deficit risk factors *Ans* -Vomiting/diarrhea
