Correct Answer: D

Rationale: Obtaining a 30-minute electronic fetal monitoring (EFM) strip prior to epidural analgesia is crucial to establish a baseline for fetal heart rate and uterine activity. This baseline helps in monitoring fetal well-being during labor and assessing the effect of analgesia on the baby. It enables the healthcare team to identify any changes in the fetal heart rate pattern and uterine contractions, ensuring the safety of both the mother and the baby.

Choices A, B, and C are incorrect because having the client sit upright with legs crossed is not necessary for epidural placement, administering a bolus of lactated Ringer's solution is not typically done before epidural analgesia, and the duration of the anesthetic effect varies and is not accurately 2 hours.

Correct Answer: D

Rationale: Hypotension is a common complication of epidural anesthesia due to the vasodilation effect of the medication. Epidural anesthesia can lead to vasodilation, causing a decrease in blood pressure. This hypotension may result in decreased perfusion to vital organs and compromise maternal and fetal well-being. Tachycardia is less likely as a complication of epidural anesthesia since it tends to have a vasodilatory effect. Respiratory depression is more commonly associated with other forms of anesthesia, such as general anesthesia, rather than epidural anesthesia. Vomiting is not typically a direct complication of epidural anesthesia and is more commonly seen with other factors such as pain or medications given during labor.

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.

Correct Answer: D

Rationale: Variable decelerations can indicate umbilical cord compression, which is a concern that may arise due to the umbilical cord being compressed during labor. This compression can lead to reduced blood flow and oxygen delivery to the fetus, necessitating close monitoring and potentially interventions to alleviate the pressure on the cord. Early decelerations are typically benign and mirror the contractions, indicating fetal head compression. Accelerations are reassuring patterns that show a healthy response to fetal movement. Late decelerations are concerning as they suggest uteroplacental insufficiency, indicating potential oxygen deprivation to the fetus.

Correct Answer: A

Rationale: Rubella immunization is recommended shortly after giving birth for a pregnant individual who lacks immunity. This timing ensures the client is protected from rubella in future pregnancies. Administering the vaccine postpartum allows the body to develop immunity without posing any risk to the developing fetus during pregnancy. Option B is incorrect because administering the rubella vaccine in the third trimester can potentially expose the developing fetus to the live virus, which is not recommended. Option C is incorrect as there is a preferred timing for rubella immunization in this scenario. Option D is incorrect as waiting until the next attempt to get pregnant does not protect the current pregnancy from rubella exposure.
