A client is ordered ampicillin 0.5 g po every 6 hours. On hand are ampicillin capsules labeled 250mg. How many capsules will the nurse administer for single dose?

A) Fetal baseline rate increasing at least 5 beats per minute:
An increase in the fetal baseline heart rate of 5 beats per minute is typically not associated with uteroplacental insufficiency. A baseline increase could indicate early signs of fetal stimulation, such as from fetal movement or excitement, but it does not align with the characteristic response to uteroplacental insufficiency, which usually causes signs of distress like late decelerations or fetal heart rate variability.

B) A shallow deceleration occurring with the beginning of contractions:
A shallow deceleration with the onset of contractions may suggest early decelerations, which are typically caused by fetal head compression during labor. Early decelerations are not typically associated with uteroplacental insufficiency, which generally leads to later decelerations. Early decelerations are generally considered benign and do not indicate oxygen deprivation or fetal distress.

C) Fetal heart rate declining late in contraction and remaining depressed:
Late decelerations, where the fetal heart rate drops after the peak of a contraction and stays depressed afterward, are a classic sign of uteroplacental insufficiency. This pattern occurs due to reduced blood flow and oxygen delivery to the fetus during contractions, leading to fetal hypoxia. Late decelerations suggest compromised placental function and require prompt attention to prevent further fetal distress.

D) Variable decelerations, too unpredictable to count:
Variable decelerations, characterized by abrupt drops in fetal heart rate with varying timing and duration, are usually caused by umbilical cord compression. While these decelerations can indicate fetal distress, they are not directly linked to uteroplacental insufficiency. Uteroplacental insufficiency typically leads to late decelerations, not variable decelerations.

A) Check fetal heart rate:
The first priority when a woman's membranes spontaneously rupture is to assess fetal well-being. The nurse should immediately check the fetal heart rate (FHR) after the rupture of membranes to evaluate for any signs of fetal distress. If there are any concerns regarding the FHR, further interventions may be needed, such as adjusting the maternal position or preparing for a possible emergent delivery. Monitoring the FHR will help guide subsequent decisions regarding care.

B) Instruct her to bear down with the next contraction:
While the second stage of labor involves pushing, it is important to wait for the appropriate signs of readiness before instructing the mother to bear down. The nurse should ensure the cervix is fully dilated and that fetal descent is progressing appropriately. Rushing into pushing too early or without proper readiness can lead to maternal and fetal complications.

C) Place her legs in stirrups:
Placing the mother’s legs in stirrups is typically done once she is in the active phase of pushing (typically when the cervix is fully dilated and fetal descent is ready). It is not the first priority immediately after the membranes rupture. The nurse should first assess the fetal heart rate and ensure the woman is comfortable and ready to push before assuming the lithotomy position or placing her legs in stirrups.

D) Test a sample of the amniotic fluid for meconium:
Testing the amniotic fluid for meconium should be done if there is concern that the amniotic fluid may be stained, as meconium in the amniotic fluid can be a sign of fetal distress. However, the first action after the membranes rupture is to check the fetal heart rate. If the FHR is normal, further actions, like testing the fluid, may follow, but the priority remains assessing fetal well-being.
