A woman received 50 mcg of fentanyl intravenously 1 hour before delivery. What drug should the nurse have readily available?
Nalbuphine (Nubain).
Naloxone (Narcan).
Butorphanol (Stadol).
Promethazine (Phenergan).
The Correct Answer is B
A. Nalbuphine (Nubain): Nalbuphine is an opioid agonist-antagonist, which can be used to treat moderate to severe pain. However, it is not specifically used to reverse the effects of fentanyl. Administering Nalbuphine could potentially complicate the situation by introducing another opioid into the system.
B. Naloxone (Narcan): Naloxone is an opioid antagonist that rapidly reverses the effects of opioids like fentanyl. It is the standard treatment for opioid overdose and can quickly restore normal respiration in a person whose breathing has slowed or stopped due to opioid use. This makes it the most appropriate drug to have readily available in this scenario.
C. Butorphanol (Stadol):Butorphanol is another opioid agonist-antagonist used for pain relief. Similar to Nalbuphine, it is not used to reverse opioid effects and could complicate the patient's condition by adding another opioid to the system.
D. Promethazine (Phenergan): Promethazine is an antihistamine used to treat nausea, vomiting, and allergies. It does not have any properties that would counteract the effects of fentanyl. Therefore, it would not be useful in reversing opioid-induced respiratory depression.

Correct Answer is D
Explanation
A. Human placental lactogen (hPL) is a hormone produced by the placenta that helps regulate the metabolism of the mother and fetus, but it is not used as the basis for pregnancy tests. It plays a role in modulating the metabolic state of the mother during pregnancy to facilitate the energy supply of the fetus.
B. Estrogen (estriol) is another hormone produced by the placenta, which is important for maintaining pregnancy and preparing the body for childbirth. However, it is not the hormone detected by pregnancy tests. Estriol levels increase significantly during pregnancy but are not used as a marker for pregnancy tests.
C. Progesterone (progestin) is crucial for maintaining the uterine lining and supporting early pregnancy. While it is essential for a successful pregnancy, it is not the hormone that pregnancy tests detect. Progesterone helps prevent uterine contractions and supports the endometrium.
D. Human chorionic gonadotropin (hCG) is the hormone detected by pregnancy tests. It is produced by the placenta shortly after the embryo attaches to the uterine lining. The presence of hCG in the blood or urine is a reliable indicator of pregnancy, which is why it is the basis for pregnancy tests.
Correct Answer is C
Explanation
Choice A reason:
Charting the normal axillary temperature is not the priority in this situation. The infant's temperature is subnormal, indicating hypothermia, which requires immediate intervention.
Choice B reason:
Rechecking the infant's temperature rectally may provide a more accurate reading, but it is not the priority action at this moment. The infant's low temperature indicates the need for immediate warming to prevent further complications.
Choice C reason:
Placing the infant in a radiant warmer is the priority nursing action. The axillary temperature of 35.9°C (96.6°F) is below the normal range for a newborn, which is around 36.5-37.5°C (97.7-99.5°F). Hypothermia in newborns can be dangerous and lead to respiratory distress, metabolic problems, and other complications. A radiant warmer provides a controlled heat source to warm the infant and stabilize their body temperature.
Choice D reason:
Having the mother breastfeed the infant may help provide warmth and comfort, but it is not the priority action. The immediate concern is to raise the infant's body temperature to a safe range using a radiant warmer.
