Study Notes

Anatomy of The Genitourinary System

Ureters are shorter in children compared to adults

Anatomy of The Gastrointestinal System

The surface area of the gastrointestinal system increases with age
The lower GI tract is relatively shorter in newborns and early infancy

Pediatric Genitourinary Considerations

All nephrons are present at birth
Kidney efficiency increases with age
Immature glomeruli, tubules, and nephrons lead to quicker dehydration
Kidneys can’t adequately conserve water and solutes effectively
Children become aware of and are interested in genitals between 3-6 years of age
Increased risk of germs in genital area

Pediatric Gastrointestinal Considerations

Sucking is a primitive reflex; voluntary control of swallowing is not until 6 weeks of age
Small stomach capacity & fast peristalsis = small frequent meals needed
Intestines grow and are closer to adult function by 2 years of age
Immature liver function leads to an increased risk of jaundice in children
Being able to sense a full rectum and attempt to control it starts around age 18 months
This is when potty training can begin

Measuring Elimination

Strict I&Os mean precisely tracking all intake and output for a patient
Measure urine output in diaper-dependent patients
Infants have a higher percentage of water in their extracellular fluid (ECF) compared to adults

Sodium

Sodium is the major electrolyte in the extracellular fluid
Sodium maintains osmolarity and the balance of extracellular fluid

Description

This quiz focuses on the anatomy and physiological considerations of the genitourinary and gastrointestinal systems in children. It covers developmental differences from infancy to later childhood, including organ size, function, and maturity. Test your knowledge on how these systems evolve as children grow.
