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.

Choice A rationale

Encouraging a hands-and-knees position may help rotate a malpositioned fetus or relieve back pain, but it does not directly address hypotonic uterine dysfunction, which is characterized by weak, ineffective contractions. While it can improve maternal comfort and potentially aid in fetal descent if malpositioning is a contributing factor to slow labor progress, it will not augment the strength or frequency of contractions necessary for cervical dilation.

Choice B rationale

Providing a comfortable environment with dim lighting can promote relaxation and potentially enhance the progress of labor in cases of hypertonic uterine dysfunction (uncoordinated, painful contractions). However, in hypotonic dysfunction, the issue is a lack of adequate uterine muscle activity. While comfort measures are always important, they do not directly stimulate stronger contractions.

Choice C rationale

Administering oxytocin is the primary medical intervention for hypotonic uterine dysfunction. Oxytocin is a synthetic hormone that stimulates uterine smooth muscle to contract more frequently and with greater intensity. This augmentation of uterine activity aims to establish an effective labor pattern, leading to cervical dilation and fetal descent when fetopelvic disproportion has been ruled out.

Choice D rationale

Preparing for an amniotomy (artificial rupture of membranes) might be considered to augment labor if the membranes are intact. However, the question states the membranes have already ruptured. Amniotomy can sometimes stimulate contractions by releasing prostaglandins, but it is not the first-line intervention for established hypotonic dysfunction after membrane rupture, and oxytocin is generally more effective in this situation.
