Nursing Elites

1. A nurse is caring for a preterm newborn who is in an incubator to maintain a neutral thermal environment. The father of the newborn asks the nurse why this is necessary. Which of the following responses should the nurse make?

• A. Preterm newborns have a smaller body surface area than normal newborns.
• B. The added brown fat layer in a preterm newborn reduces his ability to generate heat.
• C. Preterm newborns lack adequate temperature control mechanisms.
• D. The heat in the incubator rapidly dries the sweat of preterm newborns.

Correct answer: C

Rationale: The correct answer is C because preterm newborns have immature temperature regulation mechanisms, making it difficult for them to maintain their body temperature. An incubator helps maintain a stable thermal environment. Choice A is incorrect as the body surface area is not the primary reason for needing an incubator. Choice B is incorrect because brown fat in preterm newborns actually helps generate heat. Choice D is incorrect as the purpose of the incubator is not to dry sweat but to regulate the newborn's temperature.

2. A healthcare professional is assisting with the care of a client who is receiving IV magnesium sulfate. Which of the following medications should the healthcare professional anticipate administering if magnesium sulfate toxicity is suspected?

• A. Nifedipine
• B. Pyridoxine
• C. Ferrous sulfate
• D. Calcium gluconate

Correct answer: D

Rationale: Calcium gluconate is the antidote for magnesium sulfate toxicity. In cases of magnesium sulfate toxicity, calcium gluconate is administered to counteract the effects of magnesium and restore calcium levels. Magnesium toxicity can lead to symptoms such as muscle weakness, respiratory depression, and cardiac arrhythmias. Calcium gluconate helps in reversing these effects by competing with magnesium and preventing its adverse manifestations. Nifedipine is a calcium channel blocker used for conditions like hypertension and angina, not for magnesium toxicity. Pyridoxine is vitamin B6 and is not the antidote for magnesium toxicity. Ferrous sulfate is an iron supplement and is not used to treat magnesium sulfate toxicity.

3. A nurse in a prenatal clinic overhears a newly licensed nurse discussing conception with a client. Which of the following statements by the newly licensed nurse requires intervention by the nurse?

• A. Fertilization takes place in the outer third of the fallopian tube.
• B. Implantation occurs between 6 to 10 days after conception.
• C. Sperm remain viable in the woman's reproductive tract for 2 to 3 days.
• D. Bleeding or spotting can accompany implantation.

Correct answer: B

Rationale: The correct answer is B because implantation typically occurs between 6 to 10 days after conception, not 2 to 3 days. It is crucial for the nurse to intervene and provide accurate information to ensure the client receives correct education about conception. Choice A is correct as fertilization does occur in the outer third of the fallopian tube. Choice C is also accurate as sperm can remain viable in the woman's reproductive tract for 2 to 3 days. Choice D is correct as bleeding or spotting can indeed accompany implantation.

4. A client is in labor and reports increasing rectal pressure. She is experiencing contractions 2 to 3 minutes apart, each lasting 80 to 90 seconds, and a vaginal examination reveals that her cervix is dilated to 9 cm. The client is in which of the following phases of labor?

• A. Active
• B. Transition
• C. Latent
• D. Descent

Correct answer: B

Rationale: The client is in the transition phase of labor, characterized by cervical dilatation of 8 to 10 cm and contractions every 2 to 3 minutes, each lasting 45 to 90 seconds. In this phase, the cervix is nearly fully dilated, preparing the client for the pushing stage. The active phase of labor typically involves cervical dilatation from 4 to 7 cm, whereas the latent phase is the early phase of labor when the cervix dilates from 0 to 3 cm. Descent is not a phase of labor but rather refers to the movement of the fetus through the birth canal during the second stage of labor.

5. A client at 32 weeks of gestation with placenta previa is actively bleeding. Which medication should the provider likely prescribe?

• A. Betamethasone
• B. Indomethacin
• C. Nifedipine
• D. Methylergonovine

Correct answer: A

Rationale: In cases of placenta previa with active bleeding at 32 weeks of gestation, Betamethasone is prescribed to accelerate fetal lung maturity in anticipation of potential preterm delivery. This medication helps in reducing the risk of respiratory distress syndrome in the newborn, which is crucial in managing such high-risk pregnancies. Indomethacin is a nonsteroidal anti-inflammatory drug not indicated in this scenario and may be contraindicated due to its effects on platelet function and potential risk of bleeding. Nifedipine is a calcium channel blocker used for conditions like preterm labor or hypertension, not specifically for placenta previa with active bleeding. Methylergonovine is a uterotonic drug used to prevent or control postpartum hemorrhage, not indicated for placenta previa with active bleeding.
