During an initial examination in the labor room, the nurse notes a large amount of yellow-green or gray frothy and bubbly discharge around the vaginal walls with a foul smell.
The nurse suspects the woman has which type of sexually transmitted infection?

Rationales for Each Condition

Molar Pregnancy

1. Abdominal Pain: In a molar pregnancy, the uterus enlarges disproportionately due to abnormal trophoblastic growth. This excessive expansion can cause discomfort or mild cramping.
2. Blood Pressure: Molar pregnancies can be associated with gestational trophoblastic disease, which may lead to preeclampsia-like symptoms. However, this client’s blood pressure is currently within normal limits (120/78 mm Hg), so severe hypertension has not yet developed.
3. Ultrasound Findings: The presence of grape-like vesicles within the uterus and the absence of a fetal heartbeat are hallmark findings of a molar pregnancy, indicating abnormal placental tissue proliferation.
4. Perineal Pad Findings: The passage of small clear vesicles is a characteristic feature of a molar pregnancy, distinguishing it from other causes of vaginal bleeding in pregnancy.

Ectopic Pregnancy

1. Abdominal Pain: Ectopic pregnancies often cause sharp lower abdominal pain due to tubal rupture or irritation. However, in this case, the client’s pain is mild and less suggestive of tubal rupture.
2. Blood Pressure: If an ectopic pregnancy ruptures, hypotension due to internal bleeding would be expected. Since the client’s blood pressure is normal, this finding does not support an ectopic pregnancy.
3. Ultrasound Findings: The absence of a fetal heartbeat and vesicular structures inside the uterus make ectopic pregnancy unlikely, as ectopic pregnancies typically occur in the fallopian tube.
4. Perineal Pad Findings: Ectopic pregnancies rarely cause the passage of vesicular tissue, further suggesting that this is not an ectopic pregnancy.

Choice A rationale

Pounding headache, visual changes, and epigastric pain in a patient with pregnancy-induced hypertension (PIH), now known as gestational hypertension or preeclampsia, are classic signs of worsening disease and indicate central nervous system irritability and potential hepatic involvement. These symptoms suggest the condition is progressing towards severe preeclampsia and increase the risk of eclampsia, which is characterized by seizures.

Choice B rationale

Magnesium sulfate is used to prevent seizures in severe preeclampsia. While it can cause side effects such as flushing, warmth, and muscle weakness, it does not typically cause pounding headache, visual changes, or epigastric pain. These symptoms are more indicative of the underlying disease process rather than the treatment.

Choice C rationale

Anxiety due to hospitalization can cause various symptoms, but the specific combination of pounding headache, visual changes, and epigastric pain is more strongly associated with the physiological changes occurring in worsening preeclampsia rather than solely psychological distress.

Choice D rationale

Gastrointestinal upset can cause epigastric pain, but it would not typically be accompanied by pounding headache and visual changes in the context of pregnancy-induced hypertension. The constellation of these symptoms strongly points towards a worsening of the hypertensive condition and potential end-organ involvement. .
