Question | Answer |
---|---|
Causes of Postrenal Failure | Renal Calculi (Kidney Stones), Enlarged Prostate, Neurogenic Bladder |
Causes of Intrarenal Failure | Glomerulonephritis, Vascular damage, Bilateral acute pyelonephritis, Renal structure damage (Nephrons) |
Causes of Prerenal Failure | Acute blood loss/hemorrhage, hypolovemia, hypotension |
Postrenal consequences | Urinary retention, pain, azotemia (increase in BUN & Creatine)__ |
Intrarenal consequences | Oliguria, azotemia (increase in BUN & Creatine), hyperkalemia |
Prerenal consequences | Azotemia (increase in BUN & Creatine), parynchema damage if decreased perfusion to kidneys is prolonged |
Ulcerative Collitis | Chronic illness, inflammation of large intestine, episodic with bloody stools, develops psuedopolyps |
Benign Prostatic Hyperplasia clinical manifestations | Increased frequency, feeling of incomplete bladder emptying, dribbling, decreased force of urine stream, difficulty initiating stream |
Lower urinary tract infections causes | Escherichia Coli (most common), wiping back to front, holding urine for long periods of time, not voiding after sex, tight synthetic underwear, bowel incontinence |
Aldosterone | Hormone that promotes sodium and water re-absorption and excretion of potassium |
RAAS activation sequence | Decreased renal blood flow causes Renin to be released which converts angiotensinogen to angiotensin I which is converted by angiotensin-converting enzyme to angiotensin II which causes vasoconstriction and stimulates the release of aldosterone |
Hemoconcentration | A ratio > 3 between the hemoglobin and hematocrit. Divide the hematocrit by the hemoglobin (HCT/Hgb) |
Arterial end of capillary | Increased Blood Pressure, Increased Hydrostatic Pressure, Decreased Oncotic Pressure |
Venous end of capillary | Decreased Blood Pressure, Decreased Hydrostatic Pressure, Increased Oncotic Pressure |
Hydrostatic Pressure | Pushes fluid out of the capillaries |
Colloid Osmotic Pressure | Pulls fluid into its compartments |
Angiotensin-converting hormone | In pulmonary vessels, Converts Angentensin I into Angiotensin II, Part of the RAAS |
Hypercalcemia causes | Hyperparathyroidism, bone metastases, excess vitamin D |
Hypercalcemia clinical manifestations | Kidney stones, dysrhythmias, bradycardia, bone pain, fatigue, weakness, lethargy, anorexia, nausea, constipation |
Hypocalcemia causes | Blood administration, Inadequate intestinal absorption, Vitamin D deficiency |
Hypocalcemia clinical manifestations | Increased neuromuscular excitability, tingling, muscle spasms, intestinal cramping, tetany, convulsions, arrhythmias, stridor |
Hypermagnesemia causes | Renal insufficiency / Failure, Excessive intake of magnesium-containing antacids, Adrenal insufficiency |
Hypermagnesemia clinical manifestations | Loss of deep tendon reflexes, Hypotension, Skeletal smooth muscle contraction, Excess nerve function, Nausea and vomiting, Muscle weakness |
Hypomagnesemia causes | Alcoholism, Malnutrition , Malabsorption syndromes, Urinary losses, Renal tubular dysfunction , Loop diuretics |
Hypomagnesemia clinical manifestations | Behavioral changes, Irritability, Increased reflexes, Muscle cramps, Ataxia, Nystagmus, Tetany, Convulsions , Tachycardia , Hypotension |
Hyperkalemia causes | Increased intake, Shift of K+ from ICF into ECF, Decreased renal excretion, Insulin deficiency, Cell trauma |
Hyperkalemia clinical manifestations | Peaked T waves, Muscle cramps, weakness, paralysis, hypotension, drowsiness, diarrhea, abdominal cramping |
Hypokalemia causes | Alcoholism, Reduced intake of potassium, Dietary deficiency of potassium, Diarrhea, Intestinal drainage tubes, Fistulae, Laxative abuse |
Hypokalemia clinical manifestations | Prominent U waves, Confusion, Constipation, Skeletal muscle weakness, Nausea & Vomiting, Anorexia, Paralytic ileus, Smooth muscle atony, Cardiac dysrhythmias, ST segment is depressed |
Calcium Levels | Normal Range 8.8 to 10.5 mg/dl |
Magnesium Levels | Normal Range 1.8 to 3.0 mEq/L |
Potassium Levels | Normal Range 3.5 to 5.0 mEq/L |
Sodium Levels | Normal Range 135 to 145 mEq/L |
Hypernatremia causes | Infusion of hypertonic saline solutions, Renal impairment, Heart failure, Gastrointestinal losses, Oversecretion of adrenocorticotropic hormone (ACTH) or aldosterone, Cushing syndrome, Adrenal hyperplasia, Near salt water drowning |
Hypernatremia clinical manifestations | Bounding Pulse, Thirst, Weight gain, Increased blood pressure, Muscle twitching, Hyperreflexia, Confusion, Coma, Convulsions |
Hyponatremia causes | Compulsive water drinking, Loss of sodium, Inadequate sodium intake, Dilution of sodium by water excess |
Hyponatermia clinical manifestations | Headache, Pulmonary congestion, Presence of S3, Bounding pulse, Pitting edema, Increased blood pressure, Confusion |
Diabetes Mellitus Type 1 | Destruction of beta cells in pancreas, usually juvenile onset, commonly leads to hyperglycemia if not treated |
