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.

Correct Answer: C

Rationale: The correct answer is C. When a client with preeclampsia is receiving magnesium sulfate via continuous IV infusion, it is crucial to monitor the fetal heart rate (FHR) continuously. Magnesium sulfate is given to prevent seizures and is considered a high-alert medication that requires close monitoring, especially of FHR and uterine contractions. Monitoring the client's blood pressure every hour, as in choice A, is important but not as crucial as continuous FHR monitoring. Restricting the total hourly intake to 200 mL, as in choice B, is not a relevant intervention for a client receiving magnesium sulfate. Administering protamine sulfate for manifestations of toxicity, as in choice D, is incorrect as protamine sulfate is not the antidote for magnesium sulfate toxicity.

Correct Answer: A

Rationale: Levonorgestrel is an emergency contraceptive that works by inhibiting ovulation to prevent conception. It is most effective when taken as soon as possible within 72 hours following unprotected sexual intercourse. Therefore, the nurse should instruct the adolescent to take the medication promptly to maximize its effectiveness. Choice B is incorrect because levonorgestrel can be used even if the individual is on oral contraceptives. Choice C is incorrect as the efficacy of levonorgestrel is not determined by the onset of menstruation. Choice D is incorrect because levonorgestrel is a single-dose emergency contraceptive and does not provide protection for 14 days after ingestion.

Correct Answer: C

Rationale: The correct action is to monitor the client's blood pressure every 5 to 10 minutes following the first dose of anesthetic solution to assess for maternal hypotension. This is crucial to detect and manage potential complications associated with the epidural anesthesia. Positioning the client supine for a prolonged period can lead to hypotension; administering dextrose solution is not a standard practice in epidural anesthesia; ensuring NPO status for 4 hours is not necessary before epidural placement.

Correct Answer: D

Rationale: The correct answer is D, respiratory distress, as it is a clinical manifestation of hypoglycemia in newborns. Other signs of hypoglycemia include an abnormal cry, jitteriness, lethargy, poor feeding, apnea, and seizures. Hypertonia, increased feeding, and hyperthermia are not typically associated with hypoglycemia in newborns. Hypertonia is more indicative of neurological issues, increased feeding is not a common sign of hypoglycemia, and hyperthermia is not a typical symptom of low blood sugar.
