A nurse is admitting a client who has a diagnosis of preterm labor. The nurse anticipates an order by the provider for which of the following medications?
Prostaglandin E2
Methylergonovine
Terbutaline
Oxytocin
The Correct Answer is C
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.

Correct Answer is A
Explanation
Choice A reason: To stay with the client and call for help is the highest priority during a seizure, because it ensures the safety of the client and the fetus, and allows the nurse to monitor the vital signs and fetal heart rate. The nurse should also protect the client from injury and turn the client to the side to prevent aspiration.
Choice B reason: To suction the mouth to prevent aspiration is not the highest priority during a seizure, because it can cause more harm than good. Suctioning can stimulate the gag reflex and increase the risk of vomiting and aspiration. It can also injure the oral mucosa and trigger another seizure.
Choice C reason: To administer oxygen by mask is not the highest priority during a seizure, because it may not be effective or necessary. Oxygen administration can be difficult or impossible during a seizure, and it may not improve the oxygen saturation or fetal outcome. Oxygen should only be given if hypoxia is confirmed by pulse oximetry or arterial blood gas analysis.
Choice D reason: To insert an oral airway is not the highest priority during a seizure, because it can be dangerous and contraindicated. Inserting an oral airway can damage the teeth and tongue, and increase the risk of vomiting and aspiration. It can also provoke another seizure or laryngospasm. An oral airway should only be used if the client is unconscious and has no gag reflex.
Correct Answer is A
Explanation
Choice A reason: Asymmetric thigh folds is a common finding in newborns who have DDH, because the affected hip is dislocated or subluxated, causing the thigh to appear shorter and the skin folds to be uneven. The nurse should compare the number and depth of the skin folds on both sides of the groin and buttocks.
Choice B reason: Absent plantar reflexes is not a typical finding in newborns who have DDH, because it is not related to the hip joint. The plantar reflex is a normal reflex that causes the toes to curl when the sole of the foot is stroked. The nurse should assess the plantar reflex in all newborns, regardless of their hip status.
Choice C reason: Lengthened thigh on the affected side is not a usual finding in newborns who have DDH, because the opposite is true. The affected thigh is usually shorter than the unaffected thigh, due to the displacement of the femoral head from the acetabulum. The nurse should measure the length of both thighs from the anterior superior iliac spine to the medial malleolus.
Choice D reason: Inwardly turned foot on the affected side is not a specific finding in newborns who have DDH, because it can be caused by other conditions, such as metatarsus adductus or clubfoot. The inward turning of the foot is not a direct result of the hip disorder, but rather a secondary effect of the abnormal positioning of the leg. The nurse should examine the alignment and mobility of the foot and ankle.
