Which muscle loses contraction strength and is related to Urinary Retention as we age?

Detrusor muscle

A low urine specific gravity occurs in the following three situations:

Diabetes Insipidus (low ADH) Pyelonephritis & glomerulonephritis (dilute urine) Renal Failure (urine concentration is same as plasma)

most common cause of UTI

E. coli

Hypokalemia S/S

Fatigue, Anorexia, N/V, Muscle weakness, Decreased GI motility, Dysrhythmias, Paresthesia, Flat T waves on ECG

Excess calcium treatment

Fluid replacement (calcium is excreted in the urine), calcitonin, phosphate salts (calcium and phosphorus have an inverse relationship)

Creatinine is a good indicator for

GFR

Cause of glomerulonephritis

Group A strep infection occurs mostly in children after an infection of Impetigo or pharyngitis

diet for patients with acute kidney injury

High Calorie, LOW protein, LOW potassium, low sodium diet

Hyperkalemia treatment "KIND"

Kayexalate (orally/ enema) Insulin or IV diuretics Na HCO3 (reverse acidosis) Diuretics (Furosemide & Thiazides)

What are Ketones

Ketones are produced when the body burns fat for energy and fuel. Ketones occur when there is not enough insulin to help the body use sugar for energy. Since the body cannot use glucose for energy, it begins to breakdown fats leading to the formation of Ketones in the blood that spill over into the urine.

What diet restrictions should pt with CKD be on?

*Protein restriction (during elevated BUN)

Signs of transplant rejection

Stress Incontinence vs Reflex Incontinence (or urge)

Stress incontinence - involuntary loss of urine from sneezing, coughing, or changing position. Reflex incontinence is the involuntary loss of urine because of hyperreflexia in the absence of normal sensations usually associated with voiding.

Magnesium excess treatment

Calcium Gluconate

Diet teaching for end-stage renal failure.

Calories are supplied by carbohydrates and fat to prevent wasting. Protein is restricted because the breakdown of protein leads to urea, uric acid, and organic acids to accumulate quickly in the blood.

As renal failure progresses and the glomerular filtration rate (GFR) falls, which of the following changes occur?

Changes include hyperphosphatemia due to its decreased renal excretion, hypocalcemia and decreased vitamin D activation, hyperkalemia due to decreased potassium excretion, and metabolic acidosis from decreased acid secretion by the kidney and inability to regenerate bicarbonate.

Control of water balance and blood pressure, regulation of red blood cell production, synthesis of vitamin D to active form, and secretion of prostaglandins

24 hour kidney rejection

Hyper acute rejection (remove the new kidney immediately)

Sodium deficit treatment

Transient incontinence is due to?

Increased urine production related to metabolic conditions.

Indwelling vs. Straight catheter

Indwelling Catheter (Foley)-remains inserted in the bladder by means of a balloon for a period of time, the urine drains into a drainage bag. Straight Catheter performed by RN tube placed into bladder and removed immediately after urination.

peritoneal dialysis, interventions to facilitate drainage

NEVER milk tubing, turn patient side to side or elevate HOB. NEVER push catheter further in the abdomen. Check patency & abdominal girth. Maintain strict handwashing and wear mask (aseptic)
