Urinary Elimination Flashcards
The functional part of the kidney is the
Nephron
How many nephrons does each kidney have?
More than 1 million
Where is urine stored?
The bladder
Where does filtration take place/begin?
The glomerulus
Bowman’s Capsule
Surrounds the glomerulus
Average amount of urine per void
250-400mL
Normal Urine color, clarity, and odor
Light yellow, clear, without sediment, and aromatic
Nocturia
Nighttime urination
Diuresis
Water excretion
Most common microorganism that causes UTI
E. coli
Altered Urinary Function: dysuria
Renal patient
Altered Urinary Function: polyuria
Brain injury patient
Altered Urinary Function: hematuria
UTI patient
Assessment: Palpation
Start at the level of the umbilicus and move in a downward direction towards the symphysis pubis to detect bladder distention
Noninvasive technology that can estimate the volume of urine in the bladder
Bladder scan (ultrasound)
What type of collection do you get if sterile urine is not necessary?
Random urine specimen
24-hr specimen needs to be restarted if:
Any of the urine is discarded
It is contaminated with stool
It is contaminated with toilet paper
T/F: It is normal to have ketones present in the urine.
False
Two most common blood tests to detect kidney disease
BUN and Creatinine
Catheterization performed by RN vs patient
RN: procedure is sterile
Patient: procedure is clean
Intermittent catheterization
Every 6-8 hrs
Altered Urinary Function: nocturia
CHF
Prompted Voiding
Involves the use of regular checks (every 2 hrs) to determine whether the or perceives the urge to void
Bladder Training
Pts suppress the urge to void before scheduled times.
Once foley cath is removed, pt should void when
Within 8hrs
Cystitis
UTI in the bladder
Urethritis
UTI in the urethra
Pyelonephritis
UTI of the ureters, renal pelvis, or renal parenchyma
Urosepsis
Infection spreads to systemic circulation
Common in older adults as the bladder wall thins
CAUTI
Catheter acquired UTI
