A

JVD, edema, HTN, fluid overload, HF, pulmonary edema, pleural effusions

122

(with regard to AKI) uncontrolled hyponatremia or water excess can lead to

A

cerebral edema

124
Q

(With regard to AKI) What happens to potassium in AKI?

A

kidneys cannot excrete potassium–> hyperkalemia
compounded by massive tissue trauma bc damaged cells release addt’l potassium into ECF.
PLUS bleeding and blood tranfusions may cause cellular destruction, releasing MORE potassium into ECF
FINALLY, Acidosis worsens hyperkalemia as hydrogen ions enter the cells and potassium is driven out of the cells into the ECF

125
Q

neurologic changes that occur as nitrogenous wastes accumulate in brain and other nervous tissue

134
Q

flapping tremor when the wrist is extended

A

Asterixis

135
Q

What happens during the diuretic phase of AKI?

A

136
Q

How long does diuretic phase of AKI last

A

1-3 weeks

137
Q

What happens in the recovery phase of AKI?

insulin depends on the kidneys for excretion, therefore, diabetics with CKD may need ______ insulin than before the onset of CKD

A

less

170
Q

hyperinsulinemia stimulates hepatic production of

A

triglycerides
therefore, almost all pts with uremia develop dyslipidemia r/t decreased levels of lipoprotein lipase that is important in the breakdwn of lipoproteins. This means that many pts with CKD die of Cardiovascular disease.

171
Q

absence of reflexes, decreased mental status, cardiac dysrhythmias, hypotension, and respiratory failure

A

hypermagnesemia in CKD

175
Q

which type of anemia is associated with CKD?

A

normocytic, normochromic anemia. due to decreased production of erythropoietin by the kidneys.
nutritional def’s, decreased RBC lifespan, increased hemolysis of RBC, frequent blood samplings, and bleeding from GI tract add to anemia

176
Q

What about PTH and CKD?

A

parathyroid hormone is increased in CKD to compensate for decreased Ca++ and HD. PTH inhibits erythropoeisis, shorten survival of RBCs and cause bone marrow fibrosis
PTH stimulated bone demineralization (increased fractures) to release Ca++ from bones, but this releases phosphate too and phosphate decreases vit D activation by kidneys too.

177
Q

defect in platelet fxn-impaired platelet aggregation and impaired release of platelet factor III. Alterations in the coagulation system with increased concentrations of factor VIII and fibrinogen=bleeding

179
Q

Why do pts with CKD get so many infections?

A

decreased leukocyte production (enlarged spleen) as well as hyperglycemia and use of catheters, needle insertions, etc

180
Q

which would you expect to see in a HD pt? left or right sided HF?

A

Left sided, esp left ventricular hypertrophy due to so much fluid to overcome to pump out

181
Q

friction rub, chest pain, low grade fever

A

pericarditis

182
Q

why is serum calcium low in CKD?

A

as kidney fxn deteriorates, less vit D is converted to its active form, resulting in decreased serum levels. To absorb Ca++ from GI tract, activated vit D is needed. Thus decreased active vit D levels result in less Ca++ absorption from GI and therefore decreased serum Ca++

183
Q

CKD mineral and bone disorder

A

adds to morbity and mortaltiy risks bc the phosphate and calcium released from bone by PTH bind together and deposit on walls of vasculature (this may occur in the heart and disrupt conduction)
