- raises BP by vasoconstriction

Q

serum creatinine

A
  1. 5-1.2 mg/dL
    - impaired renal function is the only thing that elevates this
    - 60% of renal function is lost before this # even elevates

Q

BUN

A

10-20 mg/dL

  • byproduct of protein breakdown
  • indicates liver or renal impairment

Q

changes to renal function with CKD

A

cant filter blood so fluid & electrolytes are retained

  • fluid overload
  • increased K
  • decreased Ca (low activated VitD)
  • metabolic acidosis (kidneys cant absorb HCO3 or excrete H)

-overall decline

  • cant excrete H
  • cant reabsorb HCO3
  • kussmal breathing

Q

CKD on fluids/electrolytes

A

10-20% increase in ECF

  • risk for fluid overload
  • hyponatremia early
  • hypernatremia & hyperkalemia later
  • hypocalcemia

Q

CKD on renal system

A

nephrons larger/work harder

  • work sufficiently until 80% function lost
  • kidneys shrivel
  • BUN increases
  • UO decreases & concentration increases

  • CHF
  • atherosclerosis

Q

CKD on hematological

A

bleeding/bruising

  • platelets in toxic environment
  • uremia
  • anemia (low RBC)
  • low EPO production
  • Low RBC survival time

*can give EPO injection if super super low

Q

CKD on GI

A

anorexia (no appetite)

  • taste uremia bc vascular mouth
  • build up of ammonia in GI tract
  • ulcers bc no prostaglandins
  • GI bleeds
  • malnutrition

Q

CKD on immune

A

urea in blood disrupts WBC production

  • decreased immunity
  • risk for infection
  • generalized inflammation (body cant do anything about bc prostaglandins aren’t produced)
17
Q

CKD on integumentary

A

uremic frost (overload of uremia)

  • decreased platelets so bruising
  • dry skin
  • terrible itching
  • yellow/grey color skin
18
Q

HHS

A

glucose >600

  • ketones absent of low
  • severe cellular dehydrated
  • onset several days

-give fluids and insulin

19
Q

DKA

A

-excess glucose
->300
metabolic acidosis
-sudden onset
-glucose levels very high from stress and infection

-give fluids and insulin

20
Q

kussmaul breathing

A

deep rapid labored breathing

21

A
High TSH; Low T3 and T4
intolerance to cold
weight gain
constipation
bradycardia
thick tongue
dry skin
slowed speech

myxedema coma
hypercalcemia

22
Q
