A nurse on the labor and delivery unit is caring for a client following a vaginal examination by the provider which is documented as -1. Which of the following interpretations of this finding should the nurse make?
The cervix is effaced 1 cm.
The cervix is 1 cm dilated.
The presenting part is 1 cm below the ischial spines.
The presenting part is 1 cm above the ischial spines
The Correct Answer is D
A. The cervix being effaced is not represented by the -1 notation in a vaginal examination. Effacement is usually expressed as a percentage.
B. The -1 notation does not represent cervical dilation. Dilation is measured in centimeters.
C. The presenting part being 1 cm below the ischial spines is not correct. In the station system, if the presenting part is above the ischial spines, it is represented by a negative number. A -1 station indicates that the presenting part is 1 cm above the ischial spines.
D. The presenting part is 1 cm above the ischial spines is the correct interpretation.
In the station system, if the presenting part is above the ischial spines, it is represented by a negative number. A -1 station indicates that the presenting part is 1 cm above the ischial spines.

Correct Answer is C
Explanation
A. The pattern of contractions is important in assessing labor, but the presence of regular contractions alone does not confirm true labor. It is the changes in the cervix that indicate progress in labor.
B. The station of the presenting part (the level at which the baby's head has descended into the pelvis) is also a factor in labor, but it is not the primary indicator of true labor. Changes in the cervix are more indicative.
C. Changes in the cervix are a key sign of true labor.
True labor involves cervical effacement (thinning) and dilation (opening). These changes in the cervix signify progress in the labor process.
D. Rupture of the membranes (water breaking) can be a sign of labor, but it doesn't confirm true labor on its own. It might occur before, during, or after labor has begun.
Correct Answer is B
Explanation
The correct answer is B. An excessive amount of amniotic fluid is present.
A. Polyhydramnios is primarily characterized by an increased volume of amniotic fluid, and it is not directly linked to congenital anomalies, growth restriction, or fetal distress. However, it can be associated with certain conditions that affect fetal swallowing or the production of amniotic fluid.
B. Correct. Polyhydramnios refers to an abnormal increase in the amount of amniotic fluid surrounding the fetus. This condition can result from various factors, such as fetal anomalies, maternal diabetes, or gastrointestinal malformations in the fetus that affect the swallowing of amniotic fluid.
C. An elevated level of alpha-fetoprotein (AFP) in the amniotic fluid is associated with neural
tube defects, not polyhydramnios.
D. Carrying more than one fetus (multifetal gestation) can be associated with an increased risk of polyhydramnios due to factors such as increased fetal urine production, but the presence of polyhydramnios does not necessarily indicate a multifetal pregnancy.
