Q

What renal change associated with aging does the nurse expect an older adult client to report?
A.Concentrated urine
B.Hematuria
C.Dysuria
D.Decreased GFR (glomerular filtration rate)

A

Answer: D
Tendency decrease age; also decrease with renal failure - less renal func - give older adults lower dose becuase decrease GFR
Dilute urine

A

Abdominal assessment

25
Q

The nurse is determining whether a client has risk factors for potential kidney disease. Which question is best to elicit this information?
A.Have you been under increased stress?
B.Have you had your cholesterol checked?
C.When was the last time you had your BP checked?
D.Have you ever been told that your BP was high?

A

Answer: D
Need direct info on BP if have HTN and that puts at high risk for renal disease

26
Q

Which of the following laboratory serum findings indicates impaired kidney function?
A.Potassium 6.3
B.Blood Urea Nitrogen (BUN) 34
C.Creatinine 7
D.Phosphorus 6.5

A

Answer: C
Creatinine: 0.5-1.2
Elevated K with critically high in renal failure but could be other things - not getting rid of K
BUN high without creatinine not renal failure - could mean dehydration; both elevated means renal failure
Phosphorus (high 4.5) - high levels: cannot get rid of it from food so take meds to manage it
Only lab low with renal pats is calcium

27
Q

0.5-1.2 mg/dL
Produced when muscle and other proteins are broken down
Excreted by the kidneys - kidneys not working see increase
No common pathologic condition other than kidney diseases increases the serum creatinine level
Does not increase until at least 50% of the kidney function is lost
Increased level: kidney impairment
Decreased level: decreased muscle mass

A

Serum Creatinine

28
Q

10-20 mg/dL
Measures the effectiveness of kidney excretion of urea nitrogen
By-product of protein breakdown in the liver
Kidneys filter urea nitrogen from the blood and excrete the waste in urine
Other factors influence the BUN level, and an elevation does not always mean kidney disease is present
Increased level: liver or kidney disease, dehydration or decreased kidney perfusion, high-protein diet, infection, stress, steroid use, GI bleeding, or other situations in which blood is in body tissues; bleeding
Decreased level: malnutrition, fluid volume excess, severe hepatic damage

A

Serum blood urea nitrogen (BUN)

29
Q

Decreases indicate impaired kidney function
As renal func decreases this decreases - filtration rate decreases

A

GFR (glomerular filtration rate)

30
Q

Infection; UTI

A

WBC

31
Q

Bleeding; hematuria; bleeding in UT

A

CBC, H/H

32
Q

Infection in blood; #1 comps in UTI is this and septicemia - older people get septic quickly; catch and treat soon but also closely monitor

A

Bacteremia

33
Q

Inflammation - markers; anything cause inflammation increases

A

C-reactive protein, erythrocyte sed rate

34
Q

Kidney impairment
K, Mg, Phosphorus will be increased, and Ca will be decreased
Sometimes use dialysis/meds to lower K

A

Abnormal electrolytes

35
Q

test for bacteria, WBCs, ketones and glucose: diabetes/DKA, pH (acidic), proteins (renal failure/disease), specific gravity (concentrated/dilute), blood, color, clarity; great screening

A

Urinalysis

36
Q

issues with UTI

A

Urine culture and sensitivity

37
Q

misses one start over - lot off this: creatinine clearance; on ice for odor
All urine in the designated time frame must be collected

A

Composite urine collections (full 24 hour)

38
Q

Serum Creatinine
Serum blood urea nitrogen (BUN)
GFR (glomerular filtration rate)
Other serum labs:
Urinalysis
Urine culture and sensitivity
Composite urine collections (full 24 hour)
Creatinine clearance
Bladder scanners

A

Laboratory assessment

39
Q

Used to screen for post-void residual volumes and to determine the need for intermittent catheterization
See how much urine in bladder - look for s/s

A

Bladder scanners

40
Q

Which of the following microorganisms is the most common cause of urinary tract infections?
A.Streptococcus
B.Staphylococcus
C.Escherichia coli
D.Enterococcus

A

Answer: C
Contamination from rectal area and found in stool

41
Q

The client is scheduled to have a kidney, ureter, and bladder (KUB) X-ray. What preparation instructions should the nurse include?
A. No special preparation is required
B. Client will be NPO for 6 hours
C.A sedative will be given
D. An enema will be given

A

Answer: A
Few scans abdominal area where not have be NPO; most time with MRIs/CTs have be NPO - GI and renal; not invasive

42
Q

A client is scheduled for an abdominal CT with contrast. Which medication should be discontinued 24 hours before the procedure and for at least 48 hours?
A.Furosemide (Lasix)
B.Acetylcysteine (Musomyst)
C.Acetaminophen (Tylenol)
D.Glucophage (Metformin)

A

Answer: D
Hold until kidney func returned
Can cause lactic acidosis in kidneys
Muscle pain, fast shallow breathing, weakness, diarrhea, abdominal pain

43
Q

Imaging assessment
MRI of abdomen
Ultrasonography
Renal Scan
Cystography and cystourethrography
Cystoscopy or cystourethroscopy
Urodynamic Studies

A

Diagnostic imaging

44
Q

KUB - x-ray of the kidneys, ureters, and bladders
CT of abdomen

A

Imaging assessment

45
Q

Oral and IV dye usually given
When dye used increase fluid intake to dilute and excrete the dye
Screen for renal failure and dye allergy; creatine too high cannot do it - dye bad on kidneys
May use diuretics immediately after the dye is injected to enhance dye excretion in patients who are well hydrated
Hold Metformin (Glucophage) 24 hours prior and 48 hours after procedure or until adequate kidney function has been determined

A

CT of abdomen

46
Q

Requires a full bladder
To identify the size of the kidneys or obstruction in the kidneys or the lower urinary tract - temp urinary cathether where inject them with air to get bladder inflated

A

Ultrasonography

47
Q

Radioisotope injected IV to examine the perfusion, function, and structure of the kidneys; inject radioactive dye

A

Renal Scan

48
Q

Cystography: bladder
Cystourethrography: bladder and urethra
X-rays using contrast dye instilled directly into bladder via urinary catheter; issues with renal failure; not affect kidneys as much; just going into bladder
Pre procedure:
Post Care:

A

Cystography and cystourethrography

49
Q

Urinary catheter will be placed

A

Pre procedure: - Cystography and cystourethrography

50
Q

Monitor for infection, urine output
Encourage fluid intake
Peeing ok
Instilled dye via cathether

A

Post Care: - Cystography and cystourethrography

51
Q

Endoscopic procedure performed for diagnosis or treatment
Scope into bladder and urethra
Can do interventions - look in UT with scope
Operative procedure and informed consent required
General or under local anesthesia with sedation
Preparation: light evening meal, NPO after midnight (invasive and anesthesia), bowel preparation
Postoperative care

A

Cystoscopy or cystourethroscopy

52

54
Q

A client has undergone a kidney biopsy. What does the nurse monitor for in this client related to this procedure?
A.Nausea and vomiting
B.Amount and color of urine
C.Urinary retention and pain
D.Urgency and dysuria

A

Answer: B
Sample of kidney - check for bleeding; very vascular so risk for bleeding very high so monitor for bleeding frequently after
Flank pain and bleeding
Dramatic drops in BP - bleeding into body - retroperitoneal bleeding so keep close eye

55
Q

Most are performed percutaneously (through the skin and other tissues) using ultrasound or CT guidance so comps less common
Informed consent required
NPO for 4-6 hours before procedure
See changes act quickly
Coagulation studies completed prior because of the risk for bleeding - bleed quickly
Local anesthesia with sedation
Nursing interventions post biopsy

A

Kidney biopsy

56
Q

For 24 hours monitor dressing site, VS, urine output, H/H: Major risk for bleeding
Monitor for internal bleeding: suspected with flank pain, decreased BP, decreasing urine output
Strict bed rest in a supine position with a back roll for 2-6 hours post biopsy - put pressure roll and good if lean on it to keep pressure on it
Monitor for hematuria: most common complication
If bleeding occurs, IV fluids and mass PRBC’s may be required
If bleeding is extensive, surgery or a nephrectomy may be required - take kidney if extensive enough

A

Nursing interventions post biopsy - Kidney biopsy
