The nurse is performing an initial assessment of a client in labor. What is the appropriate terminology for the relationship of the fetal body parts to one another?

A. Dry skin is a late sign of hypovolemic shock. Early shock often presents with normal skin turgor, and pallor or cool, clammy skin develops as the body compensates.
B. Being alert and oriented is expected in the early stages of hypovolemic shock because mental status changes occur later when perfusion to the brain is compromised.
C. Urinary output below 30 mL/hr is an early indication of hypovolemic shock. The kidneys are highly sensitive to decreased perfusion, and oliguria occurs as the body conserves fluid and maintains blood pressure, making this one of the first measurable signs of shock.
D. Hypotension is a late sign of hypovolemic shock. The body initially compensates with increased heart rate and vasoconstriction to maintain blood pressure, so a drop in blood pressure indicates advanced shock.

A. Head compression typically causes early decelerations, not variable decelerations. Early decelerations are gradual decreases in fetal heart rate that mirror uterine contractions and are considered a benign sign of fetal descent through the birth canal.

B. Cord compression is the most common cause of variable decelerations. These are abrupt decreases in fetal heart rate that may vary in timing, shape, and duration, often occurring independently of uterine contractions. Variable decelerations result from umbilical cord compression, which can temporarily reduce blood flow and oxygen to the fetus. Interventions focus on relieving the compression, such as repositioning the mother, providing oxygen, or increasing intravenous fluids.

C. Placental insufficiency is associated with late decelerations, which are gradual decreases in fetal heart rate that begin after the contraction starts and return to baseline after the contraction ends. Late decelerations indicate uteroplacental compromise and may signal fetal hypoxia, which is more serious than variable decelerations.

D. Normal fetal sleep patterns can cause brief, mild decreases in baseline heart rate, but these are generally not abrupt, variable decelerations seen on monitoring. Sleep-related changes are gradual and last 20–40 minutes, unlike the abrupt pattern of variable decelerations.
