The nurse reviews results of a 28 week fetal ultrasound that reveals a small for gestational age fetus and a low implanted placenta.
The nurse will plan teaching for which pregnancy complication?
Placental abruption.
Placenta accreta.
Preterm labor.
Placenta previa.
The Correct Answer is D
Choice A rationale
Placental abruption is the premature detachment of the normally implanted placenta from the uterine wall. The client's placenta is low-implanted, suggesting a placenta previa risk, not abruption. While the small for gestational age (SGA) fetus is associated with placental insufficiency, abruption is typically characterized by acute vaginal bleeding and pain, not exclusively by a low-implanted placenta on ultrasound.
Choice B rationale
Placenta accreta is an abnormal adherence of the placenta to the uterine wall, invading the myometrium. It is a major risk in clients with a history of previous cesarean births or uterine surgery. A low-implanted placenta (previa) on its own, without a history of uterine scarring, is not the primary indicator for accreta planning, which is focused on hemorrhage risk at delivery.
Choice C rationale
Preterm labor is defined as cervical changes and uterine contractions occurring between 20 and 37 weeks of gestation. While a small for gestational age (SGA) fetus and placental issues can increase the risk of preterm labor, the specific finding of a low-implanted placenta on a 28-week ultrasound points more directly to the risk of placenta previa, which is the priority teaching topic.
Choice D rationale
Placenta previa is the implantation of the placenta over or near the internal cervical os. A low-implanted placenta revealed at 28 weeks' gestation is a strong indicator of an increased risk for previa as the pregnancy progresses. The associated fetal growth restriction (SGA) is often related to the placenta's suboptimal location and functionality, requiring teaching on bleeding precautions and warning signs.

Correct Answer is A
Explanation
Choice A rationale
This response validates the client's feelings ("A woman can feel upset.”.) and employs an open-ended question ("Can you tell me more.”.) to encourage further therapeutic communication. This supportive approach recognizes the client's grief over the loss of the desired birth experience and facilitates the emotional processing necessary for bonding.
Choice B rationale
Minimizing the client's current emotional state by suggesting it will improve later is non-therapeutic, as it invalidates her present feelings and can create a communication barrier. Bonding is a process, and initial upset can hinder it, but simply waiting for improvement isn't the best response.
Choice C rationale
Suggesting a diagnosis of postpartum depression (PPD) prematurely is inappropriate and anxiety-provoking. The "baby blues," which typically include emotional lability and crying on the third day, are a normal physiological and psychological adjustment due to hormonal shifts and the reality of parenthood.
Choice D rationale
Asking a rhetorical, even accusatory question about prenatal discussions invalidates the client's feelings by suggesting she should have been prepared or better informed. It shifts the focus away from her current distress, failing to provide the needed emotional support and acceptance.
Correct Answer is D
Explanation
Choice A rationale
Fundal height measurement assesses fetal growth, which is important but less critical than fetal well-being in a bleeding emergency. Placenta previa involves placental implantation near or over the cervical os, causing painless bleeding. Fetal distress from hypovolemia or prematurity is the most immediate life threat. The normal fundal height range is approximately equal to the weeks of gestation ± 2 cm after 20 weeks.
Choice B rationale
A digital vaginal examination is contraindicated in a client with painless, bright red bleeding suspicious of placenta previa. This action could accidentally rupture the placenta or vessels, leading to catastrophic hemorrhage and fetal distress by potentially causing placental separation or tearing of the vasa previa if present.
Choice C rationale
Assessment of maternal temperature is part of a routine vital sign assessment, mainly to detect infection (chorioamnionitis), which can cause preterm labor or rupture of membranes, but is not the priority over assessing the immediate maternal and fetal response to the hemorrhage. Normal maternal temperature is about 36.1°C to 37.2°C (97.0°F to 99.0°F).
Choice D rationale
Continuous monitoring of the fetal heart rate (FHR) and contraction patterns is the most crucial assessment to determine fetal status and well-being. Bleeding from placenta previa can quickly compromise uteroplacental perfusion, leading to fetal hypoxia, distress (e.g., non-reassuring FHR patterns), or premature labor, necessitating immediate intervention. Normal FHR is 110-160 beats per minute.
