Correct Answer: A

Rationale: In cases of placenta previa with active bleeding at 32 weeks of gestation, Betamethasone is prescribed to accelerate fetal lung maturity in anticipation of potential preterm delivery. This medication helps in reducing the risk of respiratory distress syndrome in the newborn, which is crucial in managing such high-risk pregnancies. Indomethacin is a nonsteroidal anti-inflammatory drug not indicated in this scenario and may be contraindicated due to its effects on platelet function and potential risk of bleeding. Nifedipine is a calcium channel blocker used for conditions like preterm labor or hypertension, not specifically for placenta previa with active bleeding. Methylergonovine is a uterotonic drug used to prevent or control postpartum hemorrhage, not indicated for placenta previa with active bleeding.

Correct Answer: C

Rationale: The client in active labor displaying irritability, the urge to have a bowel movement, nausea, vomiting, and expressing frustration indicates that they are in the transition phase of labor. This phase typically occurs just before entering the second stage of labor, marked by intense contractions and cervical dilation from 8 to 10 centimeters. During this phase, the client may feel overwhelmed, exhausted, and may express a sense of losing control. It is a crucial phase indicating that the client is close to delivering the baby. Choice A, the second stage of labor, is characterized by complete cervical dilation and the birth of the baby, not the symptoms described in the scenario. Choice B, the fourth stage, is the period following the delivery of the placenta, not the phase before giving birth. Choice D, the latent phase, is the early phase of labor where contractions are mild and occur at irregular intervals, not the phase described in the scenario.

Correct Answer: D

Rationale: Infections such as gonorrhea, chlamydia, and HIV can be treated during labor or immediately following birth to prevent transmission to the newborn. It is crucial to identify and treat these infections promptly to reduce the risk of vertical transmission to the infant. Therefore, all the given options are correct as they can be treated during labor or immediately following birth to prevent transmission to the newborn. Other choices are incorrect because only gonorrhea, chlamydia, and HIV can be effectively treated during labor or immediately after birth to prevent vertical transmission.

Correct Answer: C

Rationale: Shortness of breath is a symptom that can indicate a serious side effect of oral contraceptives, such as a potential blood clot in the lungs. This condition requires immediate medical attention to prevent complications. Choices A, B, and D are not typically associated with serious side effects of oral contraceptives and are considered normal or common side effects that do not require urgent medical attention.

Correct Answer: D

Rationale: The correct answer is D: Neural tube defects. Folic acid deficiency during pregnancy can lead to neural tube defects in the fetus, affecting the brain, spine, or spinal cord development. Iron deficiency anemia (choice A) is not directly related to folic acid deficiency. Poor bone formation (choice B) is more associated with calcium and vitamin D deficiencies. Macrosomic fetus (choice C) refers to a baby with excessive birth weight and is not a typical outcome of folic acid deficiency in pregnancy. Therefore, it is crucial for individuals of childbearing age to take recommended folic acid supplements to prevent neural tube defects.
