A

ambiguous genitalia

22
Q

patho of nephrotic syndrome?

A

Predominately 2-7 yrs (rare under 6 mo, uncommon under 1 yr, unusual after 8 yrs)

May be metabolic, biochemical, physiochemical, or immune-mediated disturbance:

basement membrane increasingly permeable to protein - albumin leaks & is lost in urine (reduces serum albumin level), fluid accumulates in interstitial spaces (edema) and body cavities (ascites)

23
Q

etiology of nephrotic syndrome?

A

Massive proteinuria, hypoalbuminemia, hyperlipidemia, and edema
Primary: idiopathic nephrosis, childhood nephrosis, or minimal change nephrotic syndrome (MCNS=80%)
Secondary: after glomerular damage
Congenital: autosomal recessive

24
Q

s/s of nephrotic syndrome?

A

Weight gain
Edema around eyes, scrotum, labia, ankles-especially in the morning
Ascites (massive swelling of abdomen, will look like they are pregnant)
Poor appetite
Elevated blood pressure
Tired
Urine is frothy and decreased in volume

25
Q

therapy goals of nephrotic syndrome?

A

Reduce excretion of urinary protein & fluid retention in tissues
Prevent infection & minimize therapy complications

26
Q

nephrotic syndrome treatment?

A

Low salt diet
Severe cases fluid restriction
Edema=diuretics
25% albumin
Corticosteriods

27
Q

CMs of acute glomerulonephritis?

A

Latent period 10 days post pneumo or streptococcal & viral infections
Commonly – acute poststreptococcal glomerulonephritis (APSGN)
Proteinuria & hematuria 3-4+

28
Q

acute glomerulonephritis nursing care?

A

Those with normal BP and urine output=home tx
Sodium restriction for those with edema and BP
Daily wt most useful means of assessing fluid balance
Pts w/ edema, HTN and gross hematuria may seize

29
Q

acute glomerulonephritis etiology?

A

AGN – manifestation of systemic disorder
Peak age 6-7 yrs old, uncommon younger than 2 yrs
Occurs in boys 2:1
ASO indicates post strep infection
Reduced C3 –improvement of disease=risingC3

30
Q

patho of Hemolytic Uremic Syndrome?

A

Primary site endothelial lining of the small glomerular arterioles-swell and occluded with deposits of platelets and fibrin clots.
Red blood cells are damaged moving through partially occluded blood vessels.
Damaged cells removed by spleen causing acute hemolytic anemia = thrombocytopenia

31
Q

Hemolytic Uremic Syndrome triad?

A

anemia, thrombocytopenia, and renal failure

32
Q

Hemolytic Uremic Syndrome CMs?

A

Primarily in infants 6 mos to 5 yr old
Acquired hemolytic anemia, thrombocytopenia, renal injury/failure, and CNS symptoms
Associated with e.coli (undercooked ground beef), unpasteurized milk or fruit juice (apple), sprouts, lettuce, salami or drinking-swimming in sewage-contaminated water
Begins with gastro or URI

33
Q

Hemolytic Uremic Syndrome treatment?

A

Hemodialysis or peritoneal dialysis (for those anuric for 24 hrs, or oliguria w/uremia or HTN & seizures)
FFP and plasmapheresis, fresh/washed packed cells, remove plasma from blood and replace with FFP
Emergency support for family and child

34
Q

Hemolytic Uremic Syndrome prognosis?

A

Prompt tx = 95% recovery
Residual renal impairment 10-50%
Complications: chronic renal failure, HTN, CNS disorders

35
Q

wilms tumor patho?

A

Nephroblastoma-most common malignant renal & intra-abdominal tumor in childhood
Peak age 3 yrs
No method of identifying gene carriers at this time
Slightly favors left kidney-10% both kidneys
7/1 million Caucasian children, 3x more African-American than Asian

36
Q

wilms tumor CMs?

A

Associated with aniridia (no iris in eyes), hemihypertrophy (1 side of body larger). Beckwith-Wiedemann syndrome (overgrowth syndrome)
Metastasis rare
Dx with radiographic studies, abd ultrasound, hematologic & biochemical studies, urinalysis

37
Q

nursing care for wilms tumor?

A

Surgery asap removing tumor (keep encapsulated), affected kidney, and adjacent adrenal gland
Prognosis for localized (stage I-II) 90% success
May reoccur in lung
DO NOT PALPATE
Post op at risk for bowel obstruction
Family and child support

38
Q

etiology for acute kidney injury (AKI)?

A

Inability to excrete waste, concentrate urine, conserve electrolytes
AKI in response to inadequate perfusion, kidney disease, UT obstruction
Chronic (CKI) long standing kidney disease or anomaly
Azotemia-accumulation of nitrogenous waste in blood
Uremia-retention of nitrogenous products - toxic

39
Q

AKI patho?

A

Diminished urinary output and lethargy in a child who is dehydrated, is in shock, or has recently undergone surgery should be evaluated for possible AKI
Reduced glomerular filtration rate
Elevated BUN
Significant reductions in renal blood flow

40
Q

AKI CMs?

A

Oliguria followed by diuresis
Water intoxication and hyponatremia risk

41
Q

AKI treatment?

A

During oliguria: no Na++, CL, K+
Hyperkalemia: oral or rectal Kayexalate
HTN: meds, limit fluids and salt
Anemia: Hgb below 6g/dL w/PRBC
Seizure and cardiac failure precautions

42
Q

AKI nursing care?

A

Accurate I&O, body wt, electrolyte measurement
Limit fluid intake
Nutrition (perhaps IV) tx nausea/vomiting
Tx anxiety, stress, discomfort

43
Q

etiology of chronic kidney injury (CKI)?

A

Diseased kidneys maintain normal chemical structure of body fluids under normal conditions
Uremia
Caused by recurrent UTI, chronic pyelo/glomerulonephritis hereditary disorders, & glomerulonephropathy assoc. w/ anaphylactoid purpura and lupus erythematosus

44
Q

CKI patho?

A

Asymptomatic w/ minimal biochemical abnormalities
Damaged nephrons=kidneys maintain fluid &electrolyte balance

45
Q

s/s of CKI

A

Tired
Pallor (pale/gray skin)
Increased B/P (sometimes)
Headache
Nausea
Muscle cramps
Anorexia
Itching
Neurological involvement

46
Q

diet management for CKI?

A

Most effective means besides dialysis for reducing quantity of waste requiring renal excretion
Low in protein, potassium, sodium, phosphorous
High in carbohydrates
Unrestricted amount of fat
Limit fresh fruit and veggies  hyperkalemic
High in calcium

47
Q

supplements for CKI?

A

Rich in folic acid and iron
Water soluble vitamin supplements & D
Phosphorus can be controlled by giving phosphorus-binding agents, e.g., calcium carbonate (most common) & aluminum hydroxide

48
Q

complications of CKI?

A

Anemia-HTN-Infections
Dialysis and transplant only tx for ESRD

49
Q

Dialysis for CKI physical and emotional challenges?

A

Physical challenges:
Implanting graft, fistula or peritoneal catheter
Accessing with needle each time – goal pain free

Emotions challenges:
Denial-fear-sadness
Adolescent independence
Body changes
Relentless need for tx comes before all else
