Following delivery, the nurse places the newborn under a radiant heat warmer. Which of the following is this action used to prevent?
Cold stress.
Respiratory depression.
Thermogenesis.
Tachycardia.
The Correct Answer is A
Choice A rationale:
Placing the newborn under a radiant heat warmer is used to prevent cold stress. Newborns are at risk of losing body heat rapidly, and cold stress can lead to various complications, including respiratory distress, hypoglycemia, and metabolic acidosis. The radiant heat warmer helps maintain the baby's body temperature within the normal range, promoting overall stability and reducing the risk of cold-related issues.
Choice B rationale:
The nurse should not choose choice B, "Respiratory depression,” as the action used to prevent. Placing the newborn under a radiant heat warmer does not specifically target respiratory depression. Respiratory depression in newborns may be related to various factors, such as anesthesia exposure during delivery or certain medications, and it requires appropriate monitoring and management rather than just heat regulation.
Choice C rationale:
The nurse should not choose choice C, "Thermogenesis,” as the action used to prevent. Thermogenesis refers to the generation of heat in the body, which is essential for maintaining body temperature. While the radiant heat warmer indirectly supports thermogenesis by preventing heat loss, the main purpose of using the warmer is to prevent cold stress, as stated in choice A.
Choice D rationale:
The nurse should not choose choice D, "Tachycardia,” as the action used to prevent. Tachycardia refers to an abnormally fast heart rate, and the use of a radiant heat warmer does not specifically target this condition. The purpose of the warmer, as explained earlier, is to maintain the baby's body temperature and prevent cold stress, not to address tachycardia.

Correct Answer is A
Explanation
Choice A rationale:
The client is experiencing continuous abdominal pain and vaginal bleeding, which are key signs of abruptio placentae. This condition occurs when the placenta prematurely separates from the uterine wall before the baby is born, leading to bleeding and potential fetal distress. The history of cocaine use can be a risk factor for abruptio placentae, as cocaine use may lead to vasoconstriction and reduced blood flow to the placenta.
Choice B rationale:
Hydatidiform mole is not likely in this case because it presents with symptoms such as vaginal bleeding and a "grape-like” mass on ultrasound. The continuous abdominal pain is not typical for a hydatidiform mole.
Choice C rationale:
Preterm labor is not the likely complication in this scenario because the client is at 38 weeks of gestation, which is considered full term. Preterm labor refers to labor that occurs before 37 weeks of gestation.
Choice D rationale:
Placenta previa is not the likely complication as it presents with painless vaginal bleeding in the third trimester, and the abdominal pain described in the question suggests a different condition.
Correct Answer is A
Explanation
The correct answer is A. Initiate continuous monitoring of the FHR. For a client with placenta previa, continuous fetal heart rate (FHR) monitoring is essential to assess the baby's well-being due to the risk of fetal distress from reduced oxygen supply
Choice A reason:
Continuous FHR monitoring is a standard care practice for clients with placenta previa to promptly detect any signs of fetal distress and intervene as necessary.
Choice B reason:
Betamethasone is typically administered to enhance fetal lung maturity before 34 weeks of gestation, not for placenta previa. Its use at 35 weeks is less common unless there's a risk of preterm birth within 7 days and the patient hasn't received a previous course.
Choice C reason:
Checking the cervix can induce bleeding and is contraindicated in placenta previa because it may disturb the placental site and exacerbate bleeding.
Choice D reason:
Misoprostol is used for labor induction or to treat postpartum hemorrhage. It is not indicated for placenta previa management and can cause uterine contractions leading to increased bleeding.
