Uncontrolled maternal hyperventilation during labor results in
- A. metabolic acidosis.
- B. metabolic alkalosis.
- C. respiratory acidosis.
- D. respiratory alkalosis.
Correct Answer: D
Rationale: Uncontrolled maternal hyperventilation during labor leads to excessive elimination of carbon dioxide, causing a decrease in the partial pressure of arterial carbon dioxide (PaCO2). This results in respiratory alkalosis, as the pH of the blood increases due to a decrease in PaCO2. Metabolic acidosis (Option A) would be associated with conditions such as lactic acidosis, while metabolic alkalosis (Option B) would involve excessive loss of acid or gain of base, but in this case, the primary effect is on the respiratory system. Respiratory acidosis (Option C) would be characterized by an increase in PaCO2 leading to a decrease in pH, which is the opposite of what occurs in maternal hyperventilation.

While attending the delivery of a patient with GODM, the nurse notices the retraction of the fetal head onto the perineum. What is the nurse’s next best action?
- A. Apply fundal pressure
- B. Assist the woman to left lateral position
- C. Flex the mother to left lateral position
- D. Assist the woman to hands-and-knees position
Correct Answer: D
Rationale: The retraction of the fetal head onto the perineum during labor can be indicative of shoulder dystocia or other obstructive complications, requiring immediate action. The best response is to assist the mother into hands-and-knees position, which can relieve pressure on the perineum and help with fetal descent.
What effect will the presence of support people in labor most likely have?
- A. improve the experience of the birthing person
- B. improve the outcomes of the birthing person
- C. improve the outcomes and experience of the birthing person
- D. cause birth trauma and/or postpartum depression
Correct Answer: C
Rationale: The presence of support people during labor, such as a partner, family member, doula, or midwife, can have a positive impact on both the outcomes and experience of the birthing person. Studies have shown that having continuous support during labor can lead to shorter labor times, reduced need for medical interventions like cesarean sections or epidurals, increased satisfaction with the birth experience, and decreased likelihood of experiencing postpartum depression. Emotional support, physical comfort, and advocacy provided by support people can help the birthing person feel more empowered, confident, and less stressed during labor, ultimately leading to better outcomes and a more positive birth experience.
Cephalohematoma occurring from an operative vaginal delivery increased a newborn’s risk of developing which of the following complications?
- A. Bulging fontanels
- B. Developmental delays
- C. Jaundice
- D. Macrocephaly
Correct Answer: C
Rationale: Cephalohematomas are a common complication from operative vaginal deliveries. The accumulation of blood between the infant's skull and periosteum increases the risk of jaundice because of the breakdown of red blood cells, which can overwhelm the infant's immature liver and lead to hyperbilirubinemia.
Which assessment finding indicates that cervical dilation and/or effacement has occurred?
- A. Onset of irregular contractions
- B. Cephalic presentation at 0 station
- C. Bloody mucus drainage from vagina
- D. Fetal heart tones (FHTs) present in the lower right quadrant
Correct Answer: C
Rationale: Bloody mucus drainage from the vagina, also known as "bloody show," is a common sign that indicates cervical dilation and/or effacement has occurred in anticipation of labor. This occurs as the mucus plug, which seals the cervix during pregnancy, is released as the cervix begins to soften, dilate, and efface in preparation for childbirth. This physical change in the cervix is a significant indicator that labor is approaching. The other options listed do not directly indicate cervical changes associated with labor progression like the presence of bloody mucus drainage does.
