Week 6 Urinary and Bowel Flashcards
What are the functions of the kidneys
- filter wastes, toxins, excess ions, and H2O
- help regulate blood volume, BP, electrolytes, acid-base
- secondary functions erythropoietin, secrete renin and activate vitamin D3
What is the primary job of the nephron
formation of urine
What is the process of urinary elimination
- filling of bladder (200 to 450 mL of urine)
- activation of stretch receptors in bladder wall
- signaling to the voiding reflex center
- contraction of detrusor muscle
- conscious relaxation of external urethral sphincter
Explain typical urinary patterns
- 50-60mL of urine/hour
- five to six times per day
- normal specific gravity 1.002 to 1.030
What are some life span considerations for older adults
- kidney function decreases
- urgency and frequency common
- loss of bladder elasticity and muscle tone leads to nocturia and incomplete emptying
What are the factors that affect urinary elimination
- personal
- sociocultural
- environmental
- nutrition
- hydration
- activity level
- medications such as diuretics, anticholinergic, and nephrotoxic meds
- surgery and anesthesia
What are pathological problems that can affect urinary elimination
- bladder/kidney infections
- kidney stones - renal calculi
- hypertrophy of the prostate (benign prostatic hyperplasia)
- mobility problems
- cardiovascular and metabolic disorders (decreased blood flow through glomeruli)
- neurological conditions
- communications problems
- alteration in cognition
What are things that you can do to promote normal urination
- provide privacy with curtains or doors
- assist with positioning (males = standing, women = seated upright)
- facilitate toileting routines (identify the client’s pattern)
- promote adequate fluids and nutrition
- assist with hygiene
What are the common urinary studies
- freshly voided specimen
- clean catch
- sterile specimen
- 24 hr urine
- urinalysis
- dipstick testing
- specific gravity
- serum (creatinine, blood urea nitrogen, glomerular filtration rate)
What are the alterations in urinary elimination
- UTIs
- urinary retention
- urinary incontinence
- urinary diversion/urostomy
What are the risk factors for impaired urinary elimination
- sexually active women
- use spermicidal contraceptive gel
- older women
- pregnant women
- enlarged prostate
- presence of indwelling catheter
- kidney stones
- diabetes mellitus
- immunocompromised
- history of UTI
What are the symptoms related to impaired urinary elimination
- bladder spasms
- burning with urination
- chills
- dysuria
- edema
- fever
- flank pain due to kidney infection
- foul smelling urine
- hematuria
- urinary frequency
What are the evaluations (lab tests) you would do for impaired urinary elimination
- midstream, clean catch urine specimen for culture
- dipstick urine looking for leukocytes, blood, estrace, and nitrates
- negative dipstick does not rule out UTI
What are the treatments for impaired urinary elimination
- antibiotic treatment
- cystitis (symptomatic) oral
- pyelonephritis IV antibiotics
- phenazopyridine
- liberal fluid intake
What are the nursing interventions for urinary elimination
- prevention (remove catheter ASAP)
- teaching
- 8 to 10 8 ounce glasses fluids
- urinate when feel urge
- wipe front to back
- wear cotton underwear
- urinate after intercourse
- avoid spermicidal - if history of UTI
- avoid bubble baths
- report symptoms promptly
What are reasons for urinary retention
- obstruction in urinary tract
- neurological problems
- medications and anesthesia
- musculoskeletal
- psychological
