A nurse is caring for a pregnant woman at 30 weeks of gestation in preterm labor. The woman's physician orders
betamethasone 12 mg IM for two doses, with the first dose to begin at 11 am. In implementing this order, the nurse should:
Consult the physician, because the dose is too high.
Schedule the second dose for 11 am on the next day.
Prepare to administer the medication intramuscularly between contractions.
The Correct Answer is C
Choice a) Consult the physician, because the dose is too high is incorrect because this is not a necessary or appropriate action for a nurse who is following a valid order for betamethasone. Betamethasone is a corticosteroid that can be used to accelerate fetal lung maturation and reduce the risk of respiratory distress syndrome and other complications in preterm infants. The recommended dose for betamethasone is 12 mg IM every 24 hours for two doses, which is exactly what the physician ordered. Therefore, there is no reason to question or consult the physician about the dose, as it is within the normal range and based on evidence-based practice.
Choice b) Schedule the second dose for 11 am on the next day is incorrect because this is not a correct or accurate way to implement the order for betamethasone. Betamethasone should be given at least 24 hours apart, but not more than 48 hours apart, to achieve optimal fetal lung development and neonatal outcomes. Scheduling the second dose for 11 am on the next day would result in a 24-hour interval between the doses, which is acceptable, but not ideal. The best time to schedule the second dose would be between 24 and 48 hours after the first dose, such as at 11 pm on the same day or at 7 am on the next day.
Choice c) Prepare to administer the medication intramuscularly between contractions is correct because this is the best and most appropriate way to implement the order for betamethasone. Betamethasone should be given by intramuscular injection in a large muscle mass, such as the deltoid or gluteus, using a 21-gauge needle and a syringe with an air lock. The injection site should be cleaned with alcohol and aspirated before injecting. The medication should be administered between contractions, when the uterine blood flow is maximal and the fetal absorption is optimal. The nurse should also monitor the woman and the fetus for any adverse effects of betamethasone, such as maternal hyperglycemia, hypertension, infection, or edema, or fetal tachycardia, hypoglycemia, or infection.
Choice d) Explain to the woman that this medication will reduce her heart rate and help her to breathe easier is incorrect because this is not a true or relevant statement about betamethasone. Betamethasone does not have any direct effect on the maternal heart rate or respiratory function, as it is mainly intended to improve the fetal lung maturation and reduce the risk of respiratory distress syndrome and other complications in preterm infants.
Betamethasone may cause some side effects such as increased blood pressure, blood sugar, or fluid retention in the mother, which may affect her cardiovascular or respiratory status indirectly. However, these effects are usually transient and mild, and do not outweigh the benefits of betamethasone for the fetus. Therefore, this statement is misleading and inaccurate.

Correct Answer is D
Explanation
Choice a) A phase of the female menstrual cycle that involves the release of an egg (ovum) from one of the ovaries is incorrect because this is not the definition of Mittelschmerz, but rather the definition of ovulation. Ovulation is the process by which one or more eggs are released from the ovaries and travel to the fallopian tubes, where they can be fertilized by sperm. Ovulation usually occurs around the middle of the menstrual cycle, which is typically 28 days long, but can vary from person to person. Ovulation can be detected by changes in basal body temperature, cervical mucus, or hormone levels. Therefore, this response is inaccurate and misleading.
Choice B) A female reproductive organ in which ova or eggs are produced is incorrect because this is not the definition of Mittelschmerz, but rather the definition of ovary. The ovary is a paired organ that is located on either side of the uterus in the lower abdomen. The ovary contains thousands of follicles, which are sacs that contain immature eggs. Each month, one or more follicles mature and release an egg during ovulation. The ovary also produces hormones such as estrogen and progesterone, which regulate the menstrual cycle and pregnancy. Therefore, this response is irrelevant and inaccurate.
Choice C) The regular discharge of blood and mucosal tissue from the inner lining of the uterus through the vagina is incorrect because this is not the definition of Mittelschmerz, but rather the definition of menstruation. Menstruation is the process by which the endometrium, which is the tissue that lines the uterus and prepares for implantation of a fertilized egg, is shed and expelled through the vagina if pregnancy does not occur. Menstruation usually occurs once a month and lasts for about 3 to 7 days, but can vary from person to person. Menstruation can be accompanied by symptoms such as cramps, bloating, mood swings, or headaches. Therefore, this response is irrelevant and inaccurate.
Choice D) One-sided, lower belly pain associated with normal ovulation. Usually occurs about 14 days before the next menstrual period is correct because this is the definition of Mittelschmerz. Mittelschmerz is a German word that means "middle pain". It refers to a mild to moderate pain or discomfort that some women experience in their lower abdomen around the time of ovulation. The pain may last for a few minutes to a few hours and may switch sides from month to month depending on which ovary releases an egg. The pain may be caused by irritation or stretching of the ovarian or abdominal wall by the maturing follicle or by fluid or blood released during ovulation.
Mittelschmerz is not a sign of any disease or problem and does not require any treatment. However, it can be confused with other conditions that cause pelvic pain, such as appendicitis, ectopic pregnancy, or ovarian cysts. Therefore, women who have severe or persistent pain should consult their doctor for diagnosis and treatment. Therefore, this response is clear and accurate.
Correct Answer is D
Explanation
Choice a) Ectopic pregnancy is incorrect because this is not a condition that requires delivery by cesarean section. Ectopic pregnancy is a condition where the fertilized egg implants outside the uterus, usually in the fallopian tube. It is a life-threatening complication that can cause internal bleeding and rupture of the tube. Ectopic pregnancy cannot result in a viable baby and must be terminated as soon as possible, either by medication or surgery. Therefore, this response is irrelevant and inaccurate.
Choice b) Preeclampsia is incorrect because this is not a condition that always necessitates delivery by cesarean section. Preeclampsia is a condition where the blood pressure rises above 140/90 mmHg after 20 weeks of pregnancy, along with proteinuria and edema. It can cause complications such as eclampsia, HELLP syndrome, placental abruption, and fetal growth restriction. The only cure for preeclampsia is delivery of the baby and placenta, but the mode of delivery depends on several factors, such as the gestational age, the severity of the condition, the fetal status, and the maternal preference. Therefore, some women with preeclampsia may deliver vaginally, while
others may need a cesarean section.
Choice c) Partial abruptio placentae is incorrect because this is not a condition that always necessitates delivery by cesarean section. Abruptio placentae is a condition where the placenta separates from the uterine wall before delivery, causing vaginal bleeding, abdominal pain, uterine contractions, and fetal distress. It can be classified as partial or complete, depending on the extent of the separation. The mode of delivery for abruptio placentae depends on several factors, such as the degree of bleeding, the fetal viability, the cervical dilation, and the fetal position.
Therefore, some women with partial abruptio placentae may deliver vaginally, while others may need a cesarean section.
Choice d) Total placenta previa is correct because this is the only condition that always necessitates delivery by cesarean section. Placenta previa is a condition where the placenta covers part or all of the cervix, preventing normal delivery. It can be classified as marginal, partial, or total, depending on the degree of overlap. The mode of delivery for placenta previa depends on several factors, such as the type of previa, the amount of bleeding, the gestational age, and the fetal status. However, women with total placenta previa have no chance of delivering vaginally, as the placenta completely blocks the birth canal. Therefore, they must have a cesarean section to avoid hemorrhage and fetal compromise.
