Module 6 (Exam 1) Flashcards
Acrocyanosis
Dusky coloration of hands and feet
When is it normal?
- Normal during 1st 24 hours after birth
- May also be prompted by cold stress
Lanugo
Fine, downy hair found on all parts of the fetus except the palms and soles
Vernix caseosa
Protective, cheese-like substance present on fetal skin in utero
Neonatal transition
First few hours of life, during which the neonate stablilizes respirator and circulatory function
Surfactant
Lipoprotein secreted by alveoli to reduce surface tension of pulmonary fluids and allow the lungs to remain inflated after the first breath (slippery detergent like substance)
Periodic Breathing
Neonatal breathing pattern, characterized by pauses lasting 5 to 15 seconds, rarely associated with skin color and/or heart rate changes
Apnea
Cessation of breathing lasting more than 20 seconds and accompanied by generalized cyanosis: abnormal in the term neonate
Cold Stress
Metabolic response to loss of body heat characterized by increased oxygen needs, hypoglycemia, and metabolic acidosis
Brown Adipose Tissue (BAT)
Fat deposits in neonates providing heat-generating ability: found around kidneys, adrenals, neck, between the scapula and behind the sternum
Neutral Thermal Environment
Environment in which the infant maintains temperature without physiologic stress
Non-Shivering Thermogenesis
Metabolism of brown adipose tissue to maintain temperature
Normal Temperture Neonate
36.5-37.5 C
Normal Pulse Neonate
120-160 beats/minute
Normal Respirations Neonate
30-60 breaths/minute
Normal Neonate Cry
Strong, lusty, medium pitch
