HESI Maternity 55 Questions Quizlet

Correct Answer: A

Rationale: Corrected Rationale: Immediately after birth, newborns are at high risk for heat loss, which can lead to cold stress and associated complications. Maintaining thermal regulation is crucial to prevent hypothermia and ensure the newborn's survival. By addressing heat loss as a priority issue, the healthcare provider can help stabilize the newborn's temperature and support overall well-being. Choices B, C, and D are not the priority issues immediately after birth. While fluid balance, bleeding tendencies, and hypoglycemia are important considerations in newborn care, heat loss is the primary concern right after delivery to prevent complications related to thermal regulation.

Correct Answer: C

Rationale: The primary reason for an ultrasound at 20 weeks gestation is to assess fetal growth, gestational age, and anatomical development. This evaluation helps ensure the fetus is developing appropriately and can detect any potential issues that may require intervention. Choices A, B, and D are incorrect because at 20 weeks, the primary focus of the ultrasound is not to determine the sex of the fetus, detect chromosomal abnormalities, or assess the lecithin-sphingomyelin ratio. While these factors may be evaluated in pregnancy, they are not the primary reasons for an ultrasound at 20 weeks gestation.

Correct Answer: A

Rationale: To calculate the infusion rate in mL/hour, first, convert 2 milliunits/minute to milliunits/hour by multiplying by 60 to get 120 milliunits/hour. Then, calculate the mL/hour using the formula: milliunits/hour (120) total volume (1000 mL) � units in IV solution (10 units) = 1200 mL/hour. Therefore, the nurse should program the infusion pump to deliver 12 mL/hour to provide the prescribed dose of oxytocin. Choice B is incorrect as it does not reflect the correct calculation. Choice C is incorrect as it is not derived from the correct formula. Choice D is incorrect as it is not the result of the accurate calculation based on the provided information.

Correct Answer: C

Rationale: During the first trimester of pregnancy, it is crucial to advise pregnant clients to avoid alcohol, caffeine, and smoking. These substances can worsen nausea and harm fetal development. By eliminating these substances, the client can help alleviate nausea and create a healthier environment for the developing fetus. Choices A, B, and D are not as critical in managing nausea during the first trimester. While relaxation techniques may help, avoiding harmful substances like alcohol, caffeine, and smoking takes precedence. Increasing fluid intake can be beneficial but not as crucial as avoiding harmful substances. Eliminating snacks between meals may not be necessary for all clients and is not directly related to managing nausea in the first trimester.

Correct Answer: C

Rationale: The color and consistency of the amniotic fluid are crucial to assess as they can provide valuable information about the presence of meconium, which may indicate fetal distress. Meconium-stained amniotic fluid can lead to complications such as meconium aspiration syndrome in the newborn. Therefore, assessing the color and consistency of the amniotic fluid is the priority in this situation to ensure timely interventions if needed. Estimated amount of fluid (Choice A) may be important but not as critical as assessing for meconium. Any odor noted when membranes ruptured (Choice B) is less relevant compared to assessing for meconium. Knowing the time the membranes ruptured (Choice D) is important but does not take precedence over assessing for fetal distress indicated by meconium presence.
