(297 cards)
What statements are true about fetal lung fluid (choose all that apply):
1) About 65% is absorbed by time of birth
2) It restricts alveoli
3) Remainder is expelled in the birthing process
1) and 3) are correct
All of the following statements are true about surfactant in newborns EXCEPT:
1) It reduces surface tension within the alveoli
2) It starts to develop around 32-34 weeks gestation
3) Secretions increase during labor and immediately after birth
2) is the exception, surfactant does not develop at 32-34 weeks, it develops starting around 24-25 weeks of gestation
Which explanation of the vitamin K injection for newborns by the nurse is correct?
1) Necessary for production of clotting factors
2) Necessary for the production of platelets
3) Necessary for the production of red blood cells
1) is correct, vitamin K helps synthesize clotting factors within the liver
What is a common sign of newborn hypothermia?
1) Shivering
2) Acrocyanosis
3) Hyperglycemia
2) acrocyanosis, the body is pulling warm blood away from the extremities to the trunk to stay warm
All of the following are risk factors for newborn hypoglycemia except:
1) Paternal diabetes
2) SGA, LGA, IUGR
3) Cold stress or birth stress
1) Paternal diabetes is the exception, maternal diabetes could cause newborn hypoglycemia but not paternal (of the father)
Placing a war blanket or sheet on the scale prior to weighing a newborn prevents which type of heat loss?
1) Convection
2) Radiation
3) Conduction
4) Evaporation
1) Conduction is correct, the surface of the skin in contact with a cool surface will conduct, or transfer heat away to the cooler area
- Convection = loss of heat to cool air
- Radiation = loss of heat to a cool object nearby, but not in contact
- Evaporation = moisture heat loss from skin
A nurse in the newborn nursery receives handoff report in the morning. Which newborn should the nurse assess first?
1) Newobrn with axillary temp of 96.2F
2) Newborn with a glucose of 52 mg/dL
3) Newborn with RR of 58 breaths/minute
1) should be assessed first, the newborn with a low temperature is displaying a sign of infection or heat loss
- normal: 97.5-99.7 F (Axillary)
Which of the following statements is true about non-shivering thermogensis (NST)?
1) It increases heat production by 50%
2) It is a tertiary source of heat production in newborns
3) It metabolizes brown fat present in newborns to produce heat
3) It metabolizes brown fat is correct
- It is the primary source of heat production
- It increases heat production by 100%
First time parents are concerned that their 3-day-old infant skin is looking “yellow”. The nurse’s explaination of physiologic jaundice should include:
1) Physiological jaundice occurs during the first 24 hours of life and bilirubin levels falls on their own
2) Physiological jaundice is common and bilirubin levels peak between days 2 and 4 of life
3) Physiologic jaundice may be caused by ABO imcompatability between mother and infant
2) is the correct answer, physiologic jaundice is common, peaks after 2-4 days and slowly returns to normal by days 10-12
- Physiologic jaundice does not occur during the first 24 hours, if it occurs in the first day, this is an indication of pathologic jaundice
- ABO incompatability can cause jaundice, but it would not be physiologic, it would be pathologic jaundice
A prime indicator of neonatal spesis is:
1) Fever
2) Hypothermia
3) Hyperglycemia
2) hypothermia is correct, low temperature is a more accurate indicator of infection in newborns
- Fever is less of an indicator of spesis compared to hypothermia, but still can be an indicator of infection
- Hyperglycemia is not an indicator, hypoglycemia is more likely to be an indicator of spesis
Which of the following would be concerning in a newborn:
1) Not voiding within first 12 hours
2) A thick, tarry green-black stool at 24 hours
3) A blood glucose of 35
3) is correct, BG of 35 is low, it should be above 40 mg/dL
When are interventions always required for an APGAR score:
1) 7
2) 6 or below
3) 8-10
3) 6 or below always requires intervention
What does a ballard assessment determine?
1) normal reflexes
2) gestational age
3) gestational size
2) ballard assessment determines gestational age
- it is composed of looking at the external physical characteristics and neurologic characteristics
Nightmares and animism are devlopmentally typical in which age group:
1) Toddler
2) Pre-school
3) School-age
2) they are typically common in pre-school age children
What method would be considered most accurate and is recommended for screening temperature in infants under 1 month of age?
1) Rectal
2) Temporal
3) Tympanic
4) Axillary
1) Axilliary is the most accurate
When palpating the abdomen abdomen of a 7-year-old who is complaining of pain, what is the most appropriate nursing action?
1) Palpate most painful area first
2) Palpate least painful area first
3) Palpate for rebound tenderness
4) Percuss instead of palpate
2) Palpate least painful area first
How would you start a visit with a two year old?
1) Engage first with the patient’s caregiver
2) Jump right in and take a temperature
3) Pick up toddler and bring them to the exam table
1) Engage with patient’s caregiver first
What heart sound is produced by vibrations within the heart chambers or in the major arteries from the back-and-forth flow of blood?
1) S1, S2
2) S3, S4
3) Murmur
4) Physiologic splitting
3) murmur
The nurse palpated the anterior fontanel of a 14-month-old infant and found that it was closed. What dose this finding indicate?
1) This is a normal finding
2) This finding indicates premature closure of cranial sutures.
3) This is abnormal and the child should have a developmental evaluation.
1) This is a normal finding
Which measurement is not indicated for a 4-year-old well-child examination?
1) Blood pressure
2) Weight
3) Height
4) Head circumference
4) Head circumference, head circumference is only 0-36 months
What is the main event during birth that causes transition for the baby to extrauterine life?
Disruption of the placental circulation system
**What does fetal lung fluid do and how much is absorbed by birth?
- Fetal lung fluid helps to expand the alveoli and aids in lung development
- 65% is absorbed by birth (80-10 mL) remain
**What is surfactant and what does it do?
When does it begin to develop?
- Surfactant: a detergent-like lipoprotein that reduces surface tension in the alveoli of the lungs helping to keep them open
- It is detectable by 24-25 weeks
**What happens without surfactant? When does it increase and what is one condition that can delay production?
- Without surfactant the alveoli would collapse on exhale
- It increases during labor and just after birth
- Diabetes can delay surfactant production
