WGU D236 PATHO - MEGAN/SHAY’S STUDY GUIDES What is the primary determinant of oncotic pressure? - correct answers-Albumin Form of osmotic pressure exerted by proteins - correct answers-Oncotic Pressure What is the difference between adult and child immunity? - correct answers-Naive T Cells Fluid and electrolyte levels are regulated by _________________, which regulates actions such as thirst, ADH, the kidneys, and RAAS. - correct answers-Osmoreceptors What are the causes of dehydration? - correct answers-#Excessive loss #Inadequate intake #Both What s/sx are associated with dehydration? - correct answers-#Dry mucous membranes #Decreased skin turgor #Decreased urine output #Low blood pressure #Tachycardia #Weak heart rate #Confusion A patient with a viral illness and severe vomiting has an elevated CO2 level and pH of 7.53. She is breathing slowly. What condition does she have? - correct answers-Metabolic alkalosis The patient's pH and CO2 levels are both elevated (moving in the same direction). This indicates metabolic alkalosis. The CO2 level is high because her respiratory system is attempting to compensate for the high pH by exhaling less and retaining more CO2. Normal CO2 level - correct answers-35-45 Normal pH level - correct answers-7.35-7.45 Normal HCO3 level - correct answers-22-26 Michael's pulmonary edema leads to respiratory acidosis. How does pH impact Michael's basal metabolic panel? Choose 3 answers. His CO2 level is increased because his lungs have difficulty removing it from the bloodstream. His calcium level is reduced because the elevated concentration of H+ makes it easier for Ca+ to bind to albumin. His CO2 level is decreased because his lungs have difficulty adding it into the bloodstream. His sodium level is decreased due to hypervolemia. His K+ is elevated because, as H+ moves inside of cells in an attempt to get it out of the bloodstream, K+ moves from cells into the bloodstream. - correct answers-His CO2 level is increased because his lungs have difficulty removing it from the bloodstream.

A hormone panel was done on a patient with congestive heart failure and fluid volume overload. Which elevated hormone on the patient's chart is indicative of the body's attempt to reduce the fluid overload? Antidiuretic hormone (ADH) Brain natriuretic peptide (BNP) Aldosterone Renin - correct answers-BNP BNP is released when fluid volume excess is present.
