Newborn Physiologic Adjustments (Renal System) Flashcards
During the first few days term infants generally excrete how much urine?
15 to 16 mL/kg; output increases over the first few months.
What is the frequency of voiding?
2 to 6 times a day during the first and second days of life.
5 to 25 times during the subsequent 24 hrs.
How many and what type of urine indicates adequate fluid intake?
6 to 8 voids of pale, straw-yellow urine.
Noting the first void is important! An infant who has not voided in ______ hrs should be assessed.
24 hrs.
An infant who hasn’t voided in 24 hrs should be assessed for?
Adequate fluid intake
Bladder distention
Restlessness
Symptoms of pain
What is the range of specify gravity in newborns?
1.001 to 1.020
When is the ability to fully concentrate urine obtained?
3 months
What protects the neonate from dehydration while waiting for mothers milk to produce in 3-4 days after birth?
Neonate is somewhat protected from dehydration by its increased extracellular fluid volume.
When should the neonate reagin birth weight upon breastfeeding?
10 to 14 days depending of feeding method.
The daily fluid requirement for neonates weighing more than 1500g is _____ during the first 2 days of life?
60 t0 80 mL
The daily fluid requirement for neonates weighing more than 1500g is _____ for 3 to 7 days of life?
100 to 150 mL
The daily fluid requirement for neonates weighing more than 1500g is _____ for 8 to 30 days of life?
120 to 180 mL
The GFR rapidly increases during the first month of life as a result of postnatal physiologic changes, including..
Decreased renal vascular resistance
Increased renal blood flow
Increased filtration pressure.
Renal dysfunction resulting from physiologic abnormalities can range from?
The lack of a steady stream of urine to the gross anomalies such as hypospadias and exstrophy of the bladder.
