HESI Maternity 55 Questions Quizlet

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: D

Rationale: The client at 40 weeks of gestation with a 6 cm cervical dilation and a presenting part that is not engaged requires the most caution during an enema procedure. An unengaged presenting part increases the risk of cord prolapse, which can be a serious complication during the procedure. This situation demands careful attention to prevent potential complications and ensure the safety of the client and fetus. Choice A is incorrect as being in early labor does not pose the same level of risk as an unengaged presenting part. Choice B describes a client at 37 weeks with signs of early labor but does not indicate the same level of risk as an unengaged presenting part. Choice C involves a client at 1 cm cervical dilation and a 0 station with no mention of an unengaged presenting part, making it a less critical situation compared to an unengaged presentation, as in Choice D.

Correct Answer: B

Rationale: When a full-term infant is transferred to the nursery, the most crucial information for the LPN/LVN to receive for immediate care planning is the infant's condition at birth and any treatments received. This data helps in determining the initial care needs and monitoring requirements for the newborn. Choices A, C, and D are not as critical as the infant's condition at birth and treatment received. The length of labor and method of delivery may provide background information but may not be as essential for immediate care planning. The feeding method chosen by the parents and the history of drugs given to the mother during labor are important but do not take precedence over knowing the infant's condition and treatment received.

Correct Answer: C

Rationale: Encouraging the mother to hold and spend time with her baby is crucial after a fetal demise at 32 weeks' gestation. This action can support the mother in the grieving process, facilitate bonding, and provide closure, helping her cope with the loss of the baby. Creating a memory box with the baby's footprint and photographs could be emotionally comforting but not as immediate and impactful as encouraging direct physical contact. While offering a visit from her clergy may provide spiritual support, the immediate need is to address the physical and emotional aspects of the situation. Explaining the reasons for obtaining consent for an infant autopsy is important, but it is secondary to the immediate emotional support needed by the mother.

Correct Answer: A

Rationale: The correct answer is A: 'Prevent hemorrhagic disorders.' Phytonadione (vitamin K) is administered to newborns to prevent hemorrhagic disease by promoting blood clotting. Newborns are born with low levels of vitamin K, which is essential for blood clotting, hence the administration to prevent hemorrhagic disorders. Choice B is incorrect because phytonadione is not given to help an immature liver but to supply vitamin K. Choice C is incorrect as phytonadione is not administered to improve dietary intake but to provide essential vitamin K. Choice D is incorrect as phytonadione does not stimulate the immune system but helps with blood clotting.
