A nurse is using Naegele's rule to calculate the estimated due date of a client who reports that the first day of their last menstrual cycle was July 21st.
Which of the following should the nurse document as the client's expected due date?

Explanation

1. Moderate maternal bleeding
   • In a patient with HELLP and thrombocytopenia, bleeding suggests coagulopathy (DIC) or placental abruption. This is a serious worsening sign.
2. Ringing in ears (tinnitus)
   • Could be a side effect of magnesium sulfate toxicity or a neurological symptom of worsening preeclampsia. Either way, it’s concerning and not a sign of improvement.
3. Sharp, stabbing abdominal pain
   • RUQ/epigastric pain worsening into sharp pain raises concern for liver capsule distension or rupture (life-threatening complication of HELLP) or placental abruption. This is a red flag.
4. BP 180/100 mm Hg
   • Despite antihypertensive therapy, this is severe hypertension (≥160/110 mm Hg). Indicates poor control and worsening maternal risk.
5. FHR 80/min with absent variability
   • This is severe fetal bradycardia with no variability, indicating fetal hypoxia/distress. This is an obstetric emergency.
6. PT 12 seconds
   • Within normal range (11–13.5 sec). This suggests no current coagulopathy and is the only stable/improving finding.

Almost all findings point to worsening maternal and fetal condition, except for the PT which is stable. The nurse should immediately notify the provider, anticipate emergency delivery (likely induction or cesarean), and continue close monitoring for magnesium toxicity and bleeding complications.

Choice A rationale

Bladder distention upon palpation indicates urinary retention, meaning the client is unable to void effectively or empty the bladder completely. In the postpartum period, a full bladder can inhibit uterine contraction and increase the risk of postpartum hemorrhage because a distended bladder displaces the uterus, preventing it from clamping down appropriately. The normal range for post-void residual volume is typically less than 100 mL.

Choice B rationale

Not feeling the urge to urinate may be due to decreased bladder sensation following labor and delivery or effects of regional anesthesia, which can lead to urinary retention. Effective voiding is characterized by the ability to sense the urge to void, initiate urination, and empty the bladder, typically passing at least 150 mL per void after catheter removal.

Choice C rationale

Lateral displacement of the uterus is a common sign of a distended bladder. A full bladder pushes the uterus out of its normal midline position, impairing its ability to contract effectively, which increases the risk for uterine atony and subsequent postpartum hemorrhage. The fundus should remain firm and in the midline position after effective voiding.

Choice D rationale

The firming of the fundus with massage indicates that the uterus is contracting, which is essential for preventing postpartum hemorrhage by compressing the blood vessels at the placental site. Effective voiding allows the uterus to remain in its midline position, facilitating proper involution and contractility, which is reflected by a firm fundus.
