Tubular damage - Study guides, Class notes & Summaries

RBC production BP regulation - These are the functions of the urinary system Erythropoietin - This is used to stimulate RBC production Hypoxia Renal blood flow - The kidneys secrete erythropoietin in response to this Acute kidney injury (AKI) - This is a rapid loss of renal function Low MAP - This vital sign can be seen with acute kidney injury Raise in creatinine Lower urine output - Labs for acute kidney injury Usually reversible Can have a high mortality rate depending on what is go...

6.Following the diagnosis of acute renal failure, the nurse knows that one of the earliest manifestations of residual tubular damage is which of the following lab/diagnostic results? A)Elevated blood urea nitrogen (BUN) B)Serum creatinine elevation C)Inability to concentrateNuUrinReSINGTB.COM D)Reduced glomerular filtration rate ANSWER: A Feedback: Urine tests that measure urine osmolality, urinary sodium concentration, and fractional excretion of sodium help differentiate prerenal azot...

What is the MOA of acetaminophen? Not well understood - centrally acting - may block cytokines in the dorsal horn What are the actions of acetaminophen? Analgesic, antipyretic, raises pain threshold - is NOT anti-inflammatory What is the maximum daily dose of acetaminophen? 4g What are the indications for acetaminophen? Temporary relief of minor aches/pains and fever reduction What is a common danger about acetaminophen? There are a lot of combo products What can Tylenol do when taking...

All of the following electrolyte disorders are commonly found in a patient with chronic renal failure, except: Hypernatremia Hypocalcemia Hyperkalemia Hypophosphatemia correct answers Hypophosphatemia Feedback:Electrolyte disorders commonly seen in patients with chronic renal failure include hyperkalemia, hyperphosphatemia, hypocalcemia, and bicarbonate deficiency. The advanced practice nurse sees a 78-year-old patient who has complaints of fatigue and difficulty emptying his bladder. Ex...

What are the primary functions of the skin? correct answers *skin = largest organ in the body - protection - excretion - sensory perception - heat regulation What are the most common causes of burns? correct answers 1) thermal = dry heat, moist heat, or contact heat 2) chemical = commonly results from accidents at home/work - severity depends on > how long the chemical remains on your skin, amt of tissue exposed, chemical conc. & the action of the chemical - risk for systemic t...

Electrolytes PCCN Questions and Answers Graded A+ Causes: renal failure over-replacement cell-damage/shift out of cells (acidosis, hemolysis, sepsis, chemo) spironolactone therapy S/S: bradycardia termors/twitching N/V peaked T waves, short ST seg, blocks Hyperkalemia Treatment for hyperkalemia kayexelate insulin/glucose/HCO2/Ca++ Dialysis Aerosol albuterol Causes: Poor PO intake Renal loss (diuretics, renal tubular necrosis),amphot. B GI loss; diarrhea, vomiting ...

NUR 209 EXAM 2 MED SURG BLUEPRINT LATEST (VERIFIED) Acute Kidney Injury: (Fluid Replacement) • Promote replacement of significant fluid losses helps prevent ischemic tubular damage associated w/ trauma, burns & extensive surgery • I & O’s records & the pt.’s wt. are valuable indicators of fluid volume status. • Aggressive diuretic therapy for the pt. w/ fluid overload from any cause can lead to a reduction in renal blood flow (EX. Furosemide) Post renal Acute Kidney Injury: Clin...

1. Stages of CKD: o Stages - 5 stages 80 - 120 ml/min § 1: Kidney damage (protein in the urine) and Normal GFR > 90 § 2: Mild decrease in GFR 60 - 89 § 3a: Mild-Mod. GFR 45 - 59 § 3b: Mod-severe GFR 30 - 44 § 4: Severe decrease GFR 15 - 29 § 5: ESRD GFR < 15, uremia, cardiovascular disease. 2. Prerenal renal failure: Characterized by diminished renal perfusion resulting from a decrease in blood supply to the kidneys: NO NEPHRON damage - Decreased blood supply; intravascular ...

Impaired urinary elimination -:- 1. Anuria (absence of urine) 2. Dysuria ( painful urnination) 3. Polyuria ( multiple episodes of urinating-diabetes) 4. Urinary frequency (multiple episodes w/ little urine produced in a short time) 5. Urinary hesitancy (the urge to urinate exists, but pt having hard time starting the stream) 3 processes of urine formation -:- 1. glomerular filtration 2. tubular reabsorption 3. tubular secretion Glomerular filtration -:- The first step in ur...

2024 VTNE Laboratory Test 4 (ACTUAL TEST ) Questions and Answers (Solved) 1. Anuria Answer: absence of urination; advanced kidney failure 2. Dysuria Answer: Painful or difficult urination, often caused by an inflammation of the bladder (cystitis) or kidneys (pyelonephritis). 3. Polyuria Answer: Increase in urine output or production, caused by an error of renal tubular efficiency either as a result of toxic damage or an absence of the pituitary gland's antidiuretic hormone; common ...
