Preparation Flashcard 3
Rationale
B. Rationale: The appropriate endotracheal tube size for extremely preterm newborns < 1,000 grams at 27 weeks age of gestation is a size 2.5 mm ID. If the infant weighs 1,000–2,000 grams with a gestational age of 28–34 weeks, the appropriate size is 3.0 mm ID. If the weight is > 2,000 grams with a gestational age > 34 weeks, the appropriate size is 3.5 mm ID.
Question
You are choosing an endotracheal tube size for an extremely preterm newborn weighing < 1,000 grams with a gestational age of 27 weeks. What size endotracheal tube should you choose?
a. 2.0 mm ID
b. 2.5 mm ID
c. 3.0 mm ID
d. 3.5 mm ID
Answer
b. 2.5 mm ID
Rationale
C. Rationale: When suctioning, adjust the suction machine to a suctioning pressure of 80–100 mm Hg.
Question
You are preparing the suction machine for neonatal resuscitation. In what range should you set the suction pressure?
a. 20–40 mm Hg
b. 50–70 mm Hg
c. 80–100 mm Hg
d. 100–120 mm Hg
Answer
c. 80–100 mm Hg
Rationale
B. Rationale: The servo-controlled radiant warmer can effectively adjust the temperature if its sensor is placed on the preterm newborn. The baby’s temperature must be maintained between 36.5°C and 37.5°C.
Question
You are setting a servo-controlled radiant warming device. To maintain the optimal temperature for a preterm newborn, how should you adjust the temperature settings?
a. Between 32°C and 36°C
b. Between 36.5°C and 37.5°C
c. Between 37.0°C and 37.8°C
d. All of the above
Answer
b. Between 36.5°C and 37.5°C
