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: This is incorrect because both physiological and nonphysiological jaundice result from breakdown of erythrocytes. Jaundice is caused by the accumulation of bilirubin, a yellow pigment that is produced when red blood cells are destroyed. However, the rate and extent of hemolysis differ between the two types of jaundice.
Choice B: This is incorrect because kernicterus is a rare and serious complication of jaundice, not a usual outcome. Kernicterus occurs when bilirubin levels are very high and the pigment deposits in the brain, causing neurological damage. It can affect both physiological and nonphysiological jaundice, but it is more likely to occur in nonphysiological jaundice due to higher bilirubin levels and underlying conditions.
Choice C: This is incorrect because both physiological and nonphysiological jaundice begin at the head and progress down the body. This is because bilirubin accumulates in areas with high fat content, such as the skin, eyes, and brain. The distribution of jaundice depends on the level of bilirubin in the blood, not on the type of jaundice.
Choice D: This is the correct answer because nonphysiological jaundice appears in the first 24 hours of life, whereas physiological jaundice appears after the first 24 hours of life. Nonphysiological jaundice is caused by factors that increase hemolysis or impair bilirubin metabolism or excretion, such as blood group incompatibility, infection, liver disease, or enzyme deficiency. Physiological jaundice is caused by normal adaptation processes that occur after birth, such as increased red blood cell turnover, immature liver function, and delayed intestinal flora colonization.
Correct Answer is B
Explanation
Choice A) Wrap the cord loosely with a sterile towel saturated with warm normal saline: This is not an appropriate action because it does not relieve the compression of the cord, which can cause fetal hypoxia and acidosis. The cord should be kept moist, but not wrapped around anything.
Choice B) Place a sterile gloved hand into the vagina and hold the presenting part off the cord while calling for assistance: This is the correct action because it prevents further descent of the fetus and reduces the pressure on the cord, which can improve fetal oxygenation and blood flow. The nurse should also elevate the woman's hips and place her in a knee-chest or Trendelenburg position to reduce gravity. The nurse should call for immediate assistance and prepare for an emergency cesarean section.
Choice C) Increase the IV drip rate: This is not an appropriate action because it does not address the cause of the variable decelerations, which is cord compression. Increasing the IV fluid may cause fluid overload and worsen maternal and fetal outcomes.
Choice D) Administer oxygen to the woman via mask at 8 to 10 L/minute: This is not an appropriate action because it does not relieve the cord compression, which is the main threat to fetal well-being. Oxygen administration may be helpful in some cases of fetal distress, but it is not sufficient in this situation.
