A nurse in a provider's office is caring for a client who is at 34 weeks of gestation and at risk for placental abruption. The nurse should recognize that which of the following is the most common risk factor for abruption?
Blunt force trauma
Hypertension
Gestational diabetes mellitus
Cigarette smoking
The Correct Answer is B
Choice A reason: Blunt force trauma is a possible risk factor for placental abruption, which is a condition where the placenta detaches from the uterine wall and causes bleeding, pain, and fetal distress. However, blunt force trauma is not the most common risk factor, as it accounts for only a small percentage of cases. The most common causes of blunt force trauma are motor vehicle accidents, falls, or domestic violence.
Choice B reason: Hypertension is the most common risk factor for placental abruption, as it affects about 50% of cases. Hypertension can cause vasospasm and reduced blood flow to the placenta, which can weaken the attachment and lead to separation. Hypertension can be chronic, gestational, or related to preeclampsia.
Choice C reason: Gestational diabetes mellitus is not a risk factor for placental abruption, but rather a condition where the client develops high blood sugar levels during pregnancy and can cause complications, such as macrosomia, polyhydramnios, or neonatal hypoglycemia. Gestational diabetes mellitus does not affect the placental attachment or function.
Choice D reason: Cigarette smoking is a risk factor for placental abruption, as it can cause vasoconstriction and reduced oxygen delivery to the placenta, which can impair its growth and development. However, cigarette smoking is not the most common risk factor, as it affects about 25% of cases.

Correct Answer is C
Explanation
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 B
Explanation
The correct answer is B. No special treatment is necessary.
Choice A reason: Prone positioning is not typically recommended for a fractured clavicle in infants. It does not facilitate bone alignment in the case of clavicle fractures and is not part of standard care.
Choice B reason: This is the correct choice because clavicle fractures in newborns generally heal on their own without the need for special treatment. Parents may be instructed to pin the child’s sleeve to the front of their clothing to avoid moving the arm while it heals, but beyond gentle handling, no other special treatment is necessary. In most cases, clavicle fractures in newborns heal very quickly without any problems, and usually, no treatment is required.
Choice C reason: Immobilization and casting are not standard care for newborn clavicle fractures. These fractures typically heal without such interventions, and immobilization with a cast is not needed for these types of injuries in infants.
Choice D reason: While range-of-motion exercises might be beneficial later in the healing process, they are not the primary consideration immediately after the fracture occurs. The initial care plan focuses on gentle handling and comfort for the infant, not on exercises.
