What is glomerular filtration rate (GFR) and its normal range? Which diagnostic test can
be used to measure GFR? - -- Glomerular Filtration Rate: The amount of blood filtered
by the glomeruli in a given time. Most reliable indicator of kidney function
- Normal Range: 70-135ml/min (125 mL/min)
- GFR can be lower in older adults
- Diagnostic Test Used to measure GFR: 24-hour urine collection, based on creatinine
levels
Bicarbonate normal range and changes when kidney function is impaired - -Normal
Range: 22-26 mEq/L
Changes: Most patients in renal failure have metabolic acidosis and low serum HCO3 −
levels.
BUN normal range and changes when kidney function is impaired - -Normal Range: 10-
20 mg/dL
Changes: Nonrenal factors may ↑ BUN
BUN/Creatinine normal range and changes when kidney function is impaired - -Normal
Range: 12:1-20:1
Changes: Increased ratio may be due to conditions that ↓ blood flow to kidneys
Calcium normal range and changes when kidney function is impaired - -Normal Range:
9.0-10.5mg/dL
Changes: Lower
Creatinine normal range and changes when kidney function is impaired - -Normal:
Males 0.6-1.2mg/dL/Females 0.5-1.1mg/dL
Changes:
Phosphorus normal range and changes when kidney function is impaired - -Normal
Range: 3.5-4.5 mg/dL
Changes: Phosphorus balance is inversely related to Ca2+ balance. In kidney disease,
phosphorus levels are high
Potassium normal range and changes when kidney function is impaired - -Normal
Range: 3.5-5.0 mEq/L
Changes: High K+ levels >6 mEq/L can lead to muscle weakness and dysrhythmias.

Sodium normal range and changes when kidney function is impaired - -Normal Range:
136-145mEq/L
Changes: Lowers
Uric Acid normal range and changes when kidney function is impaired - -Normal Range:
Male 4.0-8.5 mg/dL / Female 2.7-7.3 mg/dL
Changes: Values depend on renal function, rate of purine metabolism, and diet intake of
food rich in purines.
Phosphate normal range and changes when kidney function is impaired - -Normal
Range: 3-4.5
Changes: Higher because of indirect relationship with calcium
What are the normal findings in urinalysis? - -- Bilirubin: None
- Casts: None
- Color: Amber yellow
- Culture for organisms: No organisms in bladder <10 to the 4 organisms/mL result of
normal urethral flora
- Glucose: None
- Ketones: None
- Odor: Aromatic
- Osmolality: 50-1200 mOsm
- pH: 4.6-8.0 (6.o is average)
- Protein: Random protein: 0-trace / 24h protein: 50-80mg/day
- RBCs: 0-4/hpf
- Specific gravity: 1.005-1.030
- WBCs: 0-5/hpf (elevated in UTI)
Who are at the risk of development of urinary tract infection (UTI)? - -Hospitalized
individuals with catheters, females - specifically those going through menopause,
pregnant women, people with suppressed immune systems, Age (older adults),
dehydration/malnutrition
Pyelonephritis - -Upper tract; kidney, implies inflammation (usually caused by an
infection) of the renal parenchyma and collecting system
Cystitis - -Lower tract; inflammation of the bladder
Urethritis - -Lower tract; inflammation of the urethra
Upper Tract symptoms - -fever, chills, and flank pain
NUR 315
, NUR 315
Lower Tract symptoms - -Dysuria, frequency (voiding more than every 2 hours),
urgency, and suprapubic discomfort or pressure. The urine may have grossly visible
blood (hematuria) or sediment, giving it a cloudy appearance
What are the characteristics of UTI symptoms among older patients? - -- Asymptomatic
- typically mental status changes
How would you instruct patients when they take antibiotics and over-the-counter
medicines for UTIs? - -- Take full course of antibiotics - even if symptoms are gone
continue to take it
- Use over the counter (OTC) to relieve discomfort - Pyridium (inform patient that urine
color may be orange), Urised (inform patient that urine color may be greenish/blueish)
How would you promote the prevention of UTI in community and hospital settings? - -
ADD
How would you teaching patient about preventing UTIs? - -1. Take all antibiotics as
prescribed. Symptoms may improve after 1-2 days of therapy, but organisms may still
be present.
2. Practice appropriate hygiene, including:
• Carefully clean the perineal region by separating the labia in females, or in males
pulling back the foreskin if present when cleansing.
• Wipe from front to back after urinating.
• Cleanse with warm soapy water after each bowel movement.
3. Empty the bladder before and after sexual intercourse.
4. Void regularly, about every 3-4 hours during the day.
5. Maintain adequate fluid intake.
6. Avoid vaginal douches and harsh soaps, bubble baths, powders, and sprays in the
perineal area.
7. Report to the HCP symptoms or signs of recurrent UTI (e.g., fever, cloudy urine, pain
on urination, urgency, frequency).
Glomerulonephritis - -Immunologic processes result in inflammation of the glomeruli.
NOT an infection. Bowman's capsule doesn't work
What medical history will help you to identify the risk of glomerulonephritis? - -Recent
respiratory or throat infection
What are the clinical manifestations of glomerulonephritis? - -Hematuria, proteinuria,
periorbital and peripheral edema, hypertension, flank pain
How to modify fluid intake, diet, and activity level for patient with APSGN? - -- Fluid
intake: restrict sodium and fluid intake, diuretics
