What change occurs to the uterus 2 days after birth?

Choice A reason: Intermittent fetal heart auscultation is appropriate when contractions are infrequent and the fetal heart rate is reassuring. It allows monitoring without continuous electronic fetal monitoring, especially in low-risk cases.

Choice B reason: Nipple stimulation is a natural method to promote uterine contractions by stimulating endogenous oxytocin release. However, in this case, contractions are already present, and nipple stimulation is not contraindicated.

Choice C reason: Administration of IV fluids is safe and often necessary to maintain hydration, support uteroplacental perfusion, and prevent maternal hypotension.

Choice D reason: Vaginal examinations every hour are contraindicated because the client has had ruptured membranes for 18 hours. Frequent vaginal exams increase the risk of ascending infection (chorioamnionitis). Vaginal exams should be minimized and performed only when clinically indicated.

Choice A reason: The prone position is not recommended in pregnancy. It does not improve uteroplacental blood flow and is impractical for a laboring client.

Choice B reason: The left lateral position is recommended because it relieves pressure from the gravid uterus on the inferior vena cava, improving maternal cardiac output and uteroplacental perfusion. This enhances fetal oxygenation during tachysystole.

Choice C reason: The Trendelenburg position is not appropriate. It increases maternal discomfort, does not improve placental perfusion, and may worsen respiratory compromise.

Choice D reason: The supine position is contraindicated in pregnancy because the uterus compresses the inferior vena cava, reducing venous return and cardiac output. This decreases uteroplacental blood flow and worsens fetal oxygenation.
