The FACES pain scale is appropriate for children this age and older.
3 years old
Supine (alone, on firm surface, no blankets or toys)
This is the largest muscle involved in respiration in children, as opposed to intercostal muscles in adults.
Diaphragm
All pediatric medication dosing is based on this measurement.
Weight
Separation Anxiety is greatest in this age group.
Toddler
This biometric measurement is made on children from birth until age 2, and tracks brain development.
Head Circumference or OFC (occipital-frontal circumference)
This can be used to secure IV in a child and keep it "out of sight, out of mind"
Arm board or no-no
This common cardiac finding in children is defined by increased HR with inspiration, and decreased HR with expiration.
Respiratory Sinus Arrhythmias
Slower gastric emptying effects oral medication absorption in this age group.
Infants
This is the last stage of separation anxiety, when the child becomes interested in environment and may ignore parents' return. This is sometimes viewed as a healthy adjustment, but the child has really just “given up” and is protecting themself from further separation experiences.
Detachment
Crib rails should always be kept in this position unless a caregiver is within arms reach of the patient.
Up & locked
Notify MD; do not administer 2nd dose.
Physical examination in children should go in this order.
This is the preferred IM injection site in infants
Vastus Lateralis



Adolescent
If a hospital procedure might hurt or be distressing, it should be performed here.
Procedure room.
At this age, children's vital signs are (usually) the same as an adult's.
12
When these are sunken in infants, it usually is a sign of dehydration.
Fontanelles.

This is the primary organ for medication excretion in children, which does not reach adult functioning until ~1-2 years of age. This can lead to prolonged circulation and allow medication to reach toxic levels if dosed improperly.
Kidneys (renal system)
Separation anxiety in this age group might be less obvious, as they often feel guilty and that they have something bad to cause their hospitalization.
Pre-schoolers
These are pediatric specific questions the nurse should ask about the pediatric patient's past medical history (name 2 of 4)
Prenatal history
Birth History
Immunizations
Developmental/Milestone History
A parent tells the nurse that they live in a house built before 1970. The nurse should ask about what specific potential environmental exposure?
Lead paint, asbestos
A common finding in infantas and children, these are often found to be small (< 2cm), shotty (moveable), and firm on palpation. They are usually benign unless they are large and supraclavicular.
Lymph nodes
This is the total daily maintenance IV fluid calculation for a 35kg child.
1800mL
A RN who is having difficulty communicating with this age group can ask them to draw a picture.
School aged.
