A nurse is assessing a child who has bacterial pneumonia.
Which of the following manifestations should the nurse expect?

Placenta previa is a condition where the placenta implants in the lower part of the uterus, partly or completely covering the cervical opening.

This can cause painless, bright red vaginal bleeding, usually in the third trimester. Spotting is a sign of placenta previa and should be reported to the provider immediately. Choice A is wrong because nausea is not a specific finding of placenta previa.

Nausea can occur in normal pregnancy or in other conditions such as hyperemesis gravidarum or preeclampsia.

Choice B is wrong because polyhydramnios is not a finding of placenta previa.

Polyhydramnios is a condition where there is too much amniotic fluid in the uterus, which can cause complications such as preterm labor, cord prolapse, or fetal malformations.

Choice C is wrong because uterine tenderness is not a finding of placenta previa.

Uterine tenderness is a sign of abruptio placentae, which is a condition where the placenta separates from the uterine wall before delivery.

This can cause severe abdominal pain, dark red vaginal bleeding, and fetal distress.

This is because at 12 weeks of gestation, the uterus is still low in the pelvis and the fetal heart tones are best audible through the fetal back, which is usually located just above the symphysis pubis. The fetal heart rate at this stage is normally between 120 and 180 beats per minute.
Choice B is wrong because measuring the fundal height is not necessary to determine the placement of the ultrasound stethoscope at 12 weeks of gestation. The fundal height is usually measured from 20 weeks of gestation onwards to assess fetal growth and estimate gestational age.
Choice C is wrong because placing the client in a side-lying position prior to assessing the fetal heart rate is not required at 12 weeks of gestation. This position may be helpful later in pregnancy to improve maternal blood flow and oxygen delivery to the fetus, especially if there are signs of fetal distress or hypoxia.
Choice D is wrong because performing Leopold maneuvers prior to auscultating the fetal heart rate is not appropriate at 12 weeks of gestation.
Leopold maneuvers are a series of four steps to palpate the abdomen and determine the fetal position, presentation, lie, and engagement. They are usually performed after 24 weeks of gestation when the fetus is large enough to be felt through the abdominal wall.
