A nurse is caring for a client who is 9 hours postpartum following a cesarean birth with a quantitative blood loss of 1200 mL. Which of the following findings indicates the client is experiencing a fluid volume deficit?

Choice A rationale

Vacuum-assisted delivery increases the risk of postpartum hemorrhage due to potential trauma to the birth canal and uterine atony caused by prolonged pressure or rapid extraction. The vacuum device can bruise the cervix, vagina, or perineum, leading to lacerations that bleed excessively. It can also overstretch uterine muscles, impairing their ability to contract effectively after birth.

Choice B rationale

A newborn weight of 2.948 kg (6 lb 8 oz) is within the normal weight range for a full-term infant. This weight does not typically pose an increased risk for postpartum hemorrhage. Larger infants (macrosomia, generally > 4 kg) are associated with higher risks due to increased uterine stretching and potential for prolonged labor or birth trauma.

Choice C rationale

Labor induction with oxytocin significantly increases the risk for postpartum hemorrhage, particularly due to uterine atony. Prolonged oxytocin administration can lead to desensitization of myometrial receptors, reducing the uterus's ability to contract effectively postpartum. This impaired contractility prevents compression of uterine blood vessels, resulting in excessive bleeding.

Choice D rationale

A history of uterine atony is a substantial risk factor for recurrent postpartum hemorrhage. Uterine atony is the most common cause of postpartum hemorrhage, accounting for a majority of cases. A prior history indicates a predisposition for the uterine musculature to fail in contracting adequately after birth, leading to uncontrolled blood loss.

Choice E rationale

A history of human papillomavirus (HPV) infection does not directly increase the risk of postpartum hemorrhage. HPV is a viral infection that primarily affects epithelial cells, often leading to genital warts or cervical dysplasia. It does not inherently alter uterine contractility, coagulation factors, or predispose to abnormal placental implantation, which are direct causes of hemorrhage.

Choice A rationale

Nausea, commonly known as "morning sickness," is a very common and normal physiological response during the first trimester of pregnancy, often attributed to hormonal changes, particularly rising levels of human chorionic gonadotropin (hCG) and estrogen. While uncomfortable, it does not typically indicate a need for a registered dietitian referral unless it leads to significant weight loss or hyperemesis gravidarum.

Choice B rationale

A 4.5 kg (10 lb) weight gain by 12 weeks of gestation is considered excessive for the first trimester. The recommended weight gain during the first trimester is typically 0.5 to 2 kg (1 to 4.5 lb). Such rapid weight gain can indicate an imbalanced diet or underlying nutritional issues that warrant evaluation and guidance from a registered dietitian to optimize maternal and fetal health.

Choice C rationale

Taking a multivitamin daily, especially one formulated for prenatal use, is a positive health behavior during pregnancy. Prenatal vitamins typically contain essential nutrients like folic acid and iron, which are crucial for fetal development and maternal health, reducing the risk of neural tube defects and iron deficiency anemia. This indicates appropriate nutritional supplementation, not a need for referral.

Choice D rationale

Constipation is a common complaint during pregnancy, often due to hormonal changes, such as increased progesterone, which slows gastrointestinal motility, and pressure from the growing uterus on the bowels. Eating prunes is a natural and effective dietary strategy to manage constipation, as they are a good source of fiber, promoting bowel regularity. This is a healthy coping mechanism and does not necessitate a dietitian referral.
