Genitourinary Flashcards
Exam 2 (223 cards)
Anatomy and physiology of GU
Kidney:
Urethra:
Reproductive organs:
Anatomy and physiology: Kidney
Kidney: large in relation to the stomach; prone to injury.
Anatomy and physiology: Urethra
Urethra: shorter; risk for bacteria into bladder (UTI).
Anatomy and physiology: Glomerular filtration rate:
slower in infant; risk for dehydration.
Anatomy and physiology: Bladder capacity:
Bladder capacity: 30 mL in newborn; increases to adult size by 1 year.
Anatomy and physiology: How are reproductive organs?
Reproductive organs: immature at birth until adolescence.
Anatomy and physiology:
What occurs in genitourinary tract?
Urine Formation
Excretion of waste products
Regulation of electrolytes- Blood Pressure
Control of water balance
Control of acid-Base balance
Regulation of Red Blood cell Production
Synthesis of vitamin D to active form
Regulation of calcium and phosphorus
Renal Clearance
Significant Data When Assessing Past Medical History for GU Disorders:
Past medical history
Neonatal history
Family history
Significant Data When Assessing Past Medical History for GU Disorders:
Past Medical History
Maternal polyhydramnios, oligohydramnios,
diabetes,
hypertension, or
alcohol or cocaine ingestion.
Significant Data When Assessing Past Medical History for GU Disorders:
Neonatal history
Presence of a single umbilical artery,
abdominal mass,
chromosome abnormality, or
congenital malformation.
Significant Data When Assessing Past Medical History for GU Disorders
Family history
Renal disease or uropathology,
chronic UTIs,
renal calculi,
or a history of parental enuresis.
Fluid and Electrolyte Balance:
Who is at a greater risk of fluid and electrolyte imbalance?
Children at greater risk for fluid and electrolyte imbalance
Fluid and Electrolyte Balance:
Why do children have a greater risk for fluid and electrolyte imbalance
Have a proportionately greater amount of body water
Require more fluid intake
Excrete more fluid
Fluid and Electrolyte Balance:
Caring for child with fluid and/or electrolyte imbalance
What to monitor?
Monitor for signs of:
Fluid deficit
Fluid excess
Electrolyte imbalance
What does emergent care require (F and E balance)
Emergent care sometimes required with IV replacement of fluids and electrolytes
Fluid and Electrolyte Balance
Fluid Balance:
Fluid balance: intake and output of fluid in 24-hour period is approximately the same
Fluid and Electrolyte Balance
Fluid deficit occurs when fluids are lost by:
Diaphoresis
Vomiting
Diarrhea
Hemorrhage
Fluid and Electrolyte Balance: How does fluid overload occur?
Fluid overload occurs from conditions that create impaired fluid excretion
Fluid and Electrolyte Balance: Conditions that cause impaired fluid excretion?
Kidney disease
Congestive heart failure
Administration of excessive amount of intravenous fluids
Types of Dehydration:
Isotonic dehydration
Hypotonic dehydration
Hypertonic dehydration
Types of Dehydration: Isotonic dehydration
Electrolyte and water deficits in balanced proportions
Types of Dehydration: Isotonic dehydration
How are serum sodium levels?
Serum sodium remains in normal limits (130–150 mEq/L)
What is the most common type of dehydration?
Isotonic dehydration
What is the greatest concern with isotonic dehydration?
Hypovolemic shock is greatest concern
