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?
900 mL of urine output since the birth.
Temperature 37.6° C (99.6° F).
Reports of excessive sweating.
Blood pressure 80/55 mm Hg.
The Correct Answer is D
Choice A rationale
900 mL of urine output since birth (9 hours postpartum) translates to an average of 100 mL/hour. A normal urine output is typically 0.5 to 1 mL/kg/hour, which is usually greater than 30 mL/hour for adults. This indicates adequate renal perfusion and fluid balance rather than deficit.
Choice B rationale
A temperature of 37.6° C (99.6° F) is considered a low-grade fever. While it could be an early sign of infection, it is not a direct indicator of fluid volume deficit. Normal postpartum temperature may slightly increase due to dehydration or exertion during labor but usually remains below 38°C (100.4°F).
Choice C rationale
Reports of excessive sweating could be a compensatory mechanism for fever or a response to hormonal changes postpartum, but it is not a primary indicator of fluid volume deficit. In fact, excessive sweating can contribute to fluid loss, but it is not the most definitive sign.
Choice D rationale
A blood pressure of 80/55 mm Hg, particularly with a quantitative blood loss of 1200 mL, is a significant indicator of fluid volume deficit, specifically hypovolemic shock. Normal postpartum blood pressure is usually similar to pre-pregnancy levels (e.g., 90/60 to 120/80 mmHg). The low blood pressure reflects inadequate circulatory volume compromising tissue perfusion.

Correct Answer is A
Explanation
Choice A rationale
Late decelerations indicate uteroplacental insufficiency, meaning reduced blood flow and oxygen to the fetus. Placing the client in a lateral position (left or right side) can alleviate pressure on the vena cava, improving venous return to the heart, thus increasing cardiac output and uteroplacental perfusion. This is the least invasive initial intervention.
Choice B rationale
While intravenous fluid administration may be indicated in some cases to improve maternal hydration and placental perfusion, repositioning the client is a more immediate and less invasive intervention to address uteroplacental insufficiency by optimizing maternal circulation and oxygen delivery to the fetus.
Choice C rationale
Preparing for a cesarean birth is a significant intervention reserved for persistent or severe fetal distress that does not respond to less invasive measures. Although late decelerations are concerning, immediate surgical intervention is not the first step without attempting to optimize fetal well-being through maternal repositioning.
Choice D rationale
Elevating the client's legs might slightly increase venous return, but it is not the primary intervention for late decelerations. The lateral position is more effective in relieving aortocaval compression, directly addressing the underlying issue of reduced placental blood flow, and is the established first-line intervention.
Correct Answer is ["A","C","D"]
Explanation
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.
