The most appropriate time for the nurse to encourage a laboring woman to push is during

The correct answer is: a. Hyperbilirubinemia.

Choice A: Hyperbilirubinemia

Reason: Hyperbilirubinemia in newborns is often caused by the increased breakdown of red blood cells, which have a shorter lifespan in neonates. This breakdown produces bilirubin, a yellow pigment that can accumulate in the blood, leading to jaundice. The liver of a newborn is not fully mature and may not be able to process and excrete bilirubin efficiently, resulting in hyperbilirubinemia.

Choice B: Respiratory Distress Syndrome

Reason: Respiratory Distress Syndrome (RDS) is primarily caused by a deficiency of surfactant in the lungs, which is more common in premature infants. It is not directly related to the lifespan of red blood cells. Symptoms include rapid, shallow breathing and a bluish color due to lack of oxygen.

Choice C: Polycythemia

Reason: Polycythemia is characterized by an abnormally high concentration of red blood cells. It is often due to factors like delayed cord clamping or maternal diabetes, rather than the decreased lifespan of red blood cells. Polycythemia can lead to increased blood viscosity and complications such as sluggish blood flow.

Choice D: Transient Tachypnea

Reason: Transient Tachypnea of the Newborn (TTN) is a respiratory condition caused by delayed clearance of fetal lung fluid. It typically resolves within a few days and is not related to the lifespan of red blood cells. Symptoms include rapid breathing and grunting.

A. The woman had a vacuum-assisted birth. While vacuum-assisted births can cause perineal trauma, the specific orders for ice packs, sitz baths, and stool softeners are more directly related to an episiotomy, which involves a surgical incision that requires careful postpartum care.

B. The woman is a gravida 2, para 2. This information indicates the woman's obstetric history but does not directly correlate with the need for perineal ice packs, sitz baths, and stool softeners. These orders are more specific to perineal trauma or surgical intervention.

C. The woman has an episiotomy. An episiotomy involves a surgical cut made at the opening of the vagina during childbirth, which can cause significant perineal pain and swelling. The orders for perineal ice packs, sitz baths, and stool softeners are intended to manage pain, reduce swelling, and prevent constipation, which can be particularly uncomfortable with perineal stitches.

D. The woman received epidural anesthesia. While epidural anesthesia is a common pain management technique during labor, it does not necessitate the use of perineal ice packs, sitz baths, or stool softeners postpartum. These orders are more indicative of perineal trauma or surgical intervention such as an episiotomy.
