The best time to teach non-pharmacologic pain control methods to an unprepared laboring woman is during which phase?

Choice A rationale

Nausea and vomiting are common discomforts of pregnancy, particularly in the first trimester. While they can be distressing, they are not typically indicative of an immediate life-threatening condition for the mother or fetus at 14 weeks gestation. Hyperemesis gravidarum, a more severe form, would warrant closer attention, but the description here is general.

Choice B rationale

Painless vaginal bleeding in the second or third trimester (28 weeks gestation) is a concerning sign and could indicate placenta previa or placental abruption, both of which can lead to significant maternal and fetal hemorrhage and compromise fetal oxygenation. This client requires immediate assessment to determine the cause and ensure prompt intervention if necessary.

Choice C rationale

A cough and fever at 38 weeks gestation could indicate an infection, such as influenza or pneumonia. While these conditions can be serious for a near-term pregnant woman and potentially affect the fetus, they are generally less immediately life-threatening than significant vaginal bleeding in the second or third trimester and would be addressed after the client with potential placental issues.

Choice D rationale

Missed period and vaginal spotting can be early signs of pregnancy or a threatened abortion. While it warrants investigation, it is generally not an immediate emergency requiring triage before a client with painless vaginal bleeding at 28 weeks gestation, which carries a higher risk of acute complications.

The nurse should monitor the client’s temperature due to the risk of chorioamnionitis.

Rationale for correct answers

Temperature monitoring is crucial for detecting chorioamnionitis, an infection of the amniotic sac, which is a major risk following preterm premature rupture of membranes (PPROM). PPROM increases susceptibility to ascending bacterial infection, leading to inflammation. Fever (>38°C or 100.4°F) is a primary diagnostic criterion.

Chorioamnionitis presents with maternal fever, fetal tachycardia (>160/min), uterine tenderness, and foul-smelling amniotic fluid. The client's normal temperature now (36.7°C) requires ongoing monitoring, as infection could develop rapidly.

Rationale for incorrect Response 1 options

• Magnesium levels: Magnesium sulfate is used for seizure prophylaxis in eclampsia or for neuroprotection in preterm labor. This client has no signs of either condition.
• Fundal height: Measurement assesses fetal growth and amniotic fluid levels; it is not a direct indicator of infection risk.
• Clotting factors: No evidence of coagulopathy or bleeding abnormalities; coagulation profile is normal.

Rationale for incorrect Response 2 options

• Concealed hemorrhage: No signs of placental abruption (painful bleeding, rigid abdomen). Normal hemoglobin (12.0 g/dL) supports this.
• Seizures: No hypertensive crisis or neurological symptoms suggestive of eclampsia.
• Disseminated intravascular coagulation (DIC): No abnormal coagulation markers or evidence of excessive bleeding.

Take-home points

• PPROM increases the risk of chorioamnionitis, a serious intrauterine infection. • Fever monitoring is essential, as maternal fever is an early indicator of infection. • Antibiotics are given prophylactically to reduce chorioamnionitis risk in PPROM. • Differentiation from placental abruption, eclampsia, and DIC is based on clinical and laboratory findings.
