Q

Why is each gender predisposed to unique complications that should be considered and assessed?

A

because of the variations in the anatomy of the male and female urinary systems

  • ex: females are more susceptible to develop UTIs than males because of the short length of the female urethra
  • ex: the presence of the prostate gland in males introduces the potential for complications including prostatitis, benign prostate hypertrophy (BPH) or nonmalignant enlargement of the prostate gland, or prostate cancer

Q

Renal and Urinary Assessment

A

ask questions regarding any changes in appearance (clarity and color), or odor of urine, the pattern of urination, and the ability to voluntarily control voiding

>urine typically smells like ammonia
>changes in the odor of urine may be caused by medications, hydration status, or the presence of infectious organisms

26
Q

Enuresis

A

involuntary urination at night

-due to lower urinary tract disorder

27
Q

Incontinence

A

inability to voluntarily control micturition
-due to bladder infections, trauma to the external sphincter, neurogenic bladder, trauma to the nerve innervating the urinary tract structure

28
Q

Renal Colic

A

pain radiating to the perineal or groin area

-due to ureter spasm during passage of calculi, ureter obstruction

29

  • due to prolonged/abnormal related to neurogenic bladder, obstruction or stricture to the urethra
30
Q

31
Q

Renal and Urinary System Assessment Abnormalities

  • dysuria
  • enuresis
  • frequency
  • hematuria
  • hesitancy
  • incontinence
  • nocturia
  • oliguria
  • polyuria
  • renal colic
  • retention
  • urgency
32
Q

Physical Examination should include

A
  • vital signs and weight (valuable baseline on overall health status)
  • mental status and level of consciousness
  • auscultation of the lungs (for fluid status)
  • inspection, auscultation, palpation, and percussion
33
Q

When the renal system is assessed, the location of the kidneys can be estimated by using what as a landmark?

A

using the costovertebral angle (CVA)
-formed by the lower border of the 12th rib and the spine (on the patients back, below the 12th rib next to the spine; pg 1428 in hoffman)

34
Q

Proper way to assess the renal system

A

start with inspection, auscultation and then palpation and percussion
-because these palpation and percussion amplify bowel sounds and diminish abdominal vascular sounds

35
Q

Inspection: What to look for

A

inspection of the skin, oral mucosa, abdomen, and extremities
-inspection of urethral meatus may be necessary
>skin: poor skin turgor, rough texture, pallor, yellow-gray color, flank bruising
>mouth: ammonia breath odor, stomatitis (inflammation and ulceration of oral mucosa)
>abdomen: uneven contour, unilateral abdominal mass, striae (stretch marks)
>extremities: edema
>urethral meatus: bloody or purulent discharge, skin lesions or rashes, obvious tissue trauma

36
Q

Inspection of the skin: assess for abnormal changes

A

poor skin turgor, rough texture, pallor, yellow-gray color, flank bruising

37
Q

Inspection of the mouth: assess for abnormal changes

A

ammonia breath odor, stomatitis (inflammation and ulceration of oral mucosa)

38
Q

Inspection of the abdomen: assess for abnormal changes

A

uneven contour, unilateral abdominal mass, striae (stretch marks)

39
Q

Inspection of extremities: assess for abnormal changes

A

edema

40
Q

Inspection of urethral meatus: assess for abnormal changes

A

bloody or purulent discharge, skin lesions or rashes, obvious tissue trauma

41
Q

Auscultation: what position and where to listen

A

with the patient supine, auscultate over the abdominal aorta, and each renal artery with the bell of the stethoscope

42
Q

Auscultation: what to listen for

A

listen for a bruit (a turbulent or whooshing sound produced by an increase in the volume of blood traveling through a vessel or a decrease in the diameter of a blood vessel)
-presence of a bruit indicates altered blood flow to the kidneys and warrants further investigation

43
Q

What does the presence of a bruit indicate if heard on auscultation?

A

indicates altered blood flow to the kidneys

44
Q

Palpation: what position and where to palpate

A

with the patient in a supine position, lightly palpate in all four abdominal quadrants

45
Q

Palpation: what to palpate for

A

instruct the patient to report any discomfort or tenderness upon palpation
-the bladder is typically not palpable unless distended with urine; if filled with urine, the bladder is sensitive to palpation and feels round and firm

46
Q

Palpation: how to palpate the kidneys

A

position one hand under the patient’s flank between the rib cage and the iliac crest; position the other hand over the abdomen, just below the rib cage; ask the patient to take a deep breath , and use your lower hand to raise the flank while the upper hand palpates
-the lower pole of the right kidney is occasionally palpable in some patients; the left kidney is positioned deeper than the right and is typically not palpable

47
Q

Percussion: position and where to percuss

A

patient remains supine, percuss over the symphysis pubis upward toward the umbilicus

48
Q

Percussion: what to assess for

A

dullness is the sound elicited over a distended bladder

-a bladder containing little to no urine produces no sound upon percussion

49
Q

Percussion: how to assess for flank tenderness

A

utilizing fist percussion over each kidney at the CVA (on the patients back below the 12th rib next to the spine)

  • have the patient in a sitting position and position yourself behind the patient
  • place one hand flat over the CVA; form a first with the other hand and strike it against the dorsal surface of the flattened hand; this blow to the flank area should not elicit pain or tenderness; if reports pain or tenderness it is suggestive of kidney inflammation or infection
50
Q

The nurse is assessing a patient for a routine physical examination. Which of the following are normal findings when assessing the renal and urinary systems?
A. inability to palpate the kidneys
B. CVA tenderness upon percussion
C. Absence of renal artery bruit
D. Purulent drainage from the urinary meatus
E. Tympanic sounds over an empty bladder upon percussion

A

A. Inability to palpate the kidneys

C. absence of renal artery bruit

51
Q

Laboratory Studies Include

A
  • blood tests (serum creatinine, BUN, BUN/creatinine ratio, Uric Acid, Bicarbonate, Electrolytes)
  • urine tests (bedside urine dipsticks, urinalysis, culture and sensitivity, composite urine collection, creatinine clearance, and urine cytology)
52
Q

Imaging Studies Include

A
  • bedside sonography
  • x-ray
  • intravenous urography
  • renal ultrasound

  • arteriography
  • renography (kidney scan)
  • renal biopsy
  • cystoscopy
53
Q

Age-related changes and assessment findings

A
  • kidneys decrease in size–> kidneys less palpable on examination (not really palpable anyway)
  • number of nephrons decreases, nephrons lose functioning, glomerular membrane thickens–> decreased glomerular filtration rate (GFR), increased BUN and creatinine
  • changes in loop of Henle–> decreased ability to concentrate urine, decreased effect of ADH and aldosterone, urinary frequency, risk for dehydration
  • loss of muscle tone and elasticity–> risk for urinary incontinence
  • decreased bladder capacity–> urinary urgency, frequency, and incontinence
  • enlargement of prostate gland–> urinary hesitancy, frequency, straining, slow urine stream, urinary retention
54
Q 
The nurse caring for an 85y/o female patient who presents with nocturnal polyuria incorporates which priority nursing diagnosis into the plan of care?
A. risk for deficient fluid volume
B. risk for sleep deprivation
C. risk for excess fluid volume
D. risk for urge urinary incontinence
