Answer to Question 1

3
1, 2, 4. Incorrect. These medications do not act as opioid antagonists to decrease the postnatal effects of meperidine on the neonate.
3. Correct. An opioid antagonist can be given to the newborn as one part of the treatment for neonatal narcosis, which is a state of CNS depression in the newborn produced by an opioid. Opioid antagonists such as naloxone can promptly reverse the CNS depressant effects, especially respiratory depressions.

Answer to Question 2

1
1. Correct. If the mother is Rh negative and the father is Rh positive and homozygous for the Rh factor, all the offspring will be Rh positive. Only Rh-positive offspring of an Rh-negative mother are at risk for Rh incompatibility.
2. Incorrect. Only the Rh-positive offspring of an Rh-negative mother are at risk.
3. Incorrect. If the mother is Rh negative and the father is Rh positive and heterozygous for the factor, there is a 50 chance that each infant born of the union will be Rh positive and a 50 chance that each will be born Rh negative.
4. Incorrect. Only the Rh-positive offspring of an Rh-negative mother are at risk.
