Barbiturates are usually not given for pain relief during active labor for which of the following reasons?

A.

The neonatal effects include hypotonia. hypothermia. generalized drowsiness. and reluctance to feed for the first few days.
B.

These drugs readily cross the placental barrier. causing depressive effects in the newborn 2 to 3 hours after intramuscular injection.
C.

They rapidly transfer across the placenta. and lack of an antagonist make them generally inappropriate during labor.
D.

Adverse reactions may include maternal hypotension. allergic or toxic reaction or partial or total respiratory failure

Correct Answer
C. They rapidly transfer across the placenta. and lack of an antagonist make them generally inappropriate during labor.

Explanation
Barbiturates are rapidly transferred across the placental barrier. and lack of an antagonist makes them generally inappropriate during active labor.Option A: Neonatal side effects of barbiturates include central nervous system depression. prolonged drowsiness. delayed establishment of feeding (e.g. due to poor sucking reflex or poor sucking pressure). Tranquilizers are associated with neonatal effects such as hypotonia. hypothermia. generalized drowsiness. and reluctance to feed for the first few days.Option B: Narcotic analgesic readily crosses the placental barrier. causing depressive effects in the newborn 2 to 3 hours after intramuscular injection.Option D: Regional anesthesia is associated with adverse reactions such as maternal hypotension. allergic or toxic reaction. or partial or total respiratory failure.

Which of the following actions demonstrates the nurse’s understanding of the newborn’s thermoregulatory ability?

A.

Placing the newborn under a radiant warmer.
B.

Suctioning with a bulb syringe
C.

Obtaining an Apgar score
D.

Inspecting the newborn’s umbilical cord

Correct Answer
A. Placing the newborn under a radiant warmer.

Explanation
The newborn’s ability to regulate body temperature is poor. Therefore. placing the newborn under a radiant warmer aids in maintaining his or her body temperature.Option B: Suctioning with a bulb syringe helps maintain a patent airway.Option C: Obtaining an Apgar score measures the newborn’s immediate adjustment to extrauterine life.Option D: Inspecting the umbilical cord aids in detecting cord anomalies.
