A nurse is caring for a client who is at 22 weeks of gestation and has been unable to control her gestational diabetes mellitus with diet and exercise. The nurse should anticipate a prescription from the provider for which of the following medications for the client?

Choice A reason: Prostaglandin E2 is not an appropriate medication for the client, because it is a uterotonic agent that stimulates uterine contractions and cervical ripening. Prostaglandin E2 is used to induce labor, not to stop it.

Choice B reason: Methylergonovine is not an appropriate medication for the client, because it is a uterotonic agent that causes sustained uterine contractions and vasoconstriction. Methylergonovine is used to prevent or treat postpartum hemorrhage, not to stop preterm labor.

Choice C reason: Terbutaline is an appropriate medication for the client, because it is a tocolytic agent that relaxes the uterine smooth muscle and inhibits contractions. Terbutaline is used to delay preterm labor and prolong pregnancy.

Choice D reason: Oxytocin is not an appropriate medication for the client, because it is a uterotonic agent that stimulates uterine contractions and milk ejection. Oxytocin is used to augment labor, not to stop it.

Choice A reason: Using fingertips when calming the newborn is not recommended, as it can overstimulate the immature nervous system and cause stress. Instead, the nurse should use gentle, firm, and sustained touch, such as cupping the head and feet, or swaddling the newborn.

Choice B reason: Positioning the premature infant on their abdomen is contraindicated, as it can increase the risk of sudden infant death syndrome (SIDS). The nurse should position the newborn on their back or side, with a rolled blanket or towel to support the spine and prevent flattening of the head.

Choice C reason: Keeping the newborn in a well-lit nursery is not advisable, as it can interfere with the development of the circadian rhythm and sleep patterns. The nurse should provide a dark and quiet environment for the newborn, and expose them to natural light during the day.

Choice D reason: Clustering the newborn's care activities is beneficial, as it can reduce the number of disruptions and allow for longer periods of rest and growth. The nurse should plan and coordinate the care activities, such as feeding, bathing, changing, and assessing, to minimize the stress on the newborn.
