Q

Kidneys - Function

A
  1. Maintain composition and volume of body fluid
  2. 1 million nephrons in each kidney remove Urea
  3. Creatinine and Uric acid from blood plasma to form urine
  4. Kidneys remove waste including urine
  5. body fluids remain stable if kidneys are functioning well

Q

Bladder

A
  • 3 layers of smooth muscle
  • middle layer forms an involuntary sphincter that guards the opening between the bladder & urethra
  • reservoir for urine
  • innervated by ANS
  • bladder wall stretches until the nerves are stimulated = need to urinate

Q

Full Ward Test (FWT)

Also known as a ward urinalysis test (common on admission)

A
  • Non sterile specimen collected (clean catch)
  • uses reagent strips to detect abnormalities
35
Q

Midstream Collection (MSU) - Sterile specimen container

A
  • clean the perineal area with soap and water
  • first part of void is discard
  • CAPTURE MIDDLE PART OF VOID
  • Finish voiding in the toilet
  • stored in ward fridge for up to 1 hr
  • used for culture or microbes and sensitivity to antibiotics
36
Q

Catheter collection (CSU) - Sterile specimen container

A
  • catheter clamped to prevent free flow of urine into drainage bag
  • swab the access port on the catheter drainage tube
  • withdraw urine using a sterile syringe
  • inject urine into specimen container and unclamp catheter
  • may be stored in ward fridge for up to 1 hr used for
37
Q

24 hour urine collection

A
  • place a sign in patients bathroom of the start and end times
  • Provide a 24 hr sample of renal function
  • measures levels of hormones and steroids
  • creatinine clearance and protein can be measured
38
Q

Bladder Scan - which measures volume of urine in the bladder

A
  • should be used to determine if the bladder is emptying correctly
  • male to female setting available (to compensate for uterus)
  • can provide a print out of the scan and results which can go in the patients medical history
39
Q

Post Void Residual volumes (PVR)
- Measured to determine how
completely the bladder empties
with voiding

A
  • Less than 50ml PVR is considered normal
  • when 100ml or more is retained further testing is indicated
  • High PVR volumes can increase the risk of urinary tract infection
  • the amount of urine left in the bladder is measured with the bladder scanner
40
Q

Dialysis

A
  • used to treat people who experience severely decreased
  • a mechanical way of filtering waste from the blood
  • two categories: haemodialysis and peritoneal dialysis
  • HD requires vascular access - arteriovenous (AV) fistula or AV graft
  • PD involves using blood vessels in the peritoneum to fill in for the kidneys. A fluid called dialysate is washed in & out of the peritoneal space.
  • care of either catheter site is a nursing responsibility.
41
Q

Nursing Assessment of dialysis fistula

A
  • functioning fistula produces a bruit on auscultation & a thrill on palpation
  • checked every shift
  • a bruit is normal in a fistula but abnormal in other arteries
  • the sound is produced by turbulent flow through the fistula
  • No ID band, cannulation, venepuncture or BP
42
Q

44
Q

Common renal conditions - chronic disease

A
  • occurs when kidneys have been damaged in a way that cannot be reversed.

  • E Coli, klebsiella; candida albicans; pseudomonas
46
Q

Common Renal Conditions: UTI

Signs & Symptoms

Management

A
  • antibiotics, fluids, hygiene, cotton and loose fitting underwear.
48
Q

Learning Objective 5

A

Identify the developmental, social and
cultural considerations required when
performing a renal assessment.

49
Q

Infants and children

A
  • kidneys occupy large portion of abdomen at birth
  • urine formation occurs at the third month of fetal development
  • at about 2-3 years of age the child becomes aware of bladder filling and begins to inhibit voiding
50
Q

Pregnancy

A

Full ward test - detect protein in the urine and elude to pre-eclampsia - further investigation can then be initiated

  • cannot perform a bladder scan on a woman who is pregnant or postpartum
  • fundus is palpable above pubic symphysis
51
Q

Adults and late adulthood

A
  • By 70 years of age 30-50% of glomeruli have stopped functioning
  • Decreased oestrogen results in changes to the female urethra, bladder, vagina, and pelvic floor.
  • men the prostate gland enlarges and can obstruct the flow of urine through the urethra.
52
Q

Social and cultural considerations

A

130% increase in chronic kidney disease (CKD) in last 10 years from diabetes

53
Q

Social and cultural considerations

A

higher (CKD) in pacific islander and Maori people

54
Q

Social and cultural considerations

A

urinary incontinence affects 50% of woman over age of 50 and 30% of men over 70

55
Q

Full Ward Test - Leukocytes

A

normal - non present
positive - infections
