A maternal indication for the use of vacuum extraction is
Maternal exhaustion.
Failure to progress past 0 station.
A wide pelvic outlet.
A history of rapid deliveries.
The Correct Answer is A
Choice A reason:
Maternal exhaustion is a maternal indication for the use of vacuum extraction. Vacuum extraction is a technique that can assist the mother in delivering the baby when she is unable to push effectively or when pushing poses a risk to her health. Vacuum extraction can shorten the second stage of labor and reduce maternal fatigue and distress. According to the Cleveland Clinic, vacuum extraction might be indicated if "the mother can't push anymore, either due to exhaustion or a health condition.".
Choice B reason:
Failure to progress past 0 station is not a maternal indication for the use of vacuum extraction. The station refers to the position of the baby's head in relation to the mother's pelvis. 0 station means that the baby's head is at the level of the pelvic inlet, or the narrowest part of the pelvis. Vacuum extraction is usually not performed before the baby reaches +2 station, which means that the head is 2 cm below the pelvic inlet and visible at the vaginal opening. According to the American Academy of Family Physicians, vacuum extraction should not be attempted if "the fetal head is not engaged (above 0 station).".
Choice C reason:
A wide pelvic outlet is not a maternal indication for the use of vacuum extraction. The pelvic outlet is the lower part of the pelvis that forms the exit for the baby during delivery. A wide pelvic outlet means that there is more space for the baby to pass through, which can facilitate vaginal delivery and reduce the need for instrumental assistance. Vacuum extraction is more likely to be indicated when there is a narrow pelvic outlet, which can obstruct labor and cause fetal distress.
Choice D reason:
A history of rapid deliveries is not a maternal indication for the use of vacuum extraction. Rapid deliveries, also known as precipitous deliveries, are those that occur within 3 hours of the onset of labor. Rapid deliveries can pose risks to both the mother and the baby, such as excessive bleeding, umbilical cord prolapse, or birth trauma. However, vacuum extraction is not usually indicated in these cases, as it requires time and preparation to apply the device and monitor its effects. Vacuum extraction is more likely to be indicated when labor is prolonged or stalled in the second stage, and when there is a nonreassuring fetal heart rate.

Correct Answer is A
Explanation
Choice A reason:
Hypothermia is the priority area for this newborn because the axillary temperature of 95.8° F (35.4° C) is below the normal range of 97.7° F to 99.5° F (36.5° C to 37.5° C) for newborns1. Hypothermia can lead to complications such as hypoglycemia, metabolic acidosis, and impaired oxygen delivery2. The nurse should initiate interventions to warm the newborn, such as skin-to-skin contact, radiant warmer, or swaddling2.
Choice B reason:
Deficient fluid volume is not the priority area for this newborn because the apical pulse of 114 beats per minute is within the normal range of 100 to 160 beats per minute for newborns345. A low pulse rate can indicate dehydration or shock in newborns2. The nurse should monitor the newborn's fluid intake and output, weight, and signs of dehydration, such as dry mucous membranes, sunken fontanels, and poor skin turgor2.
Choice C reason:
Impaired gas exchange is not the priority area for this newborn because the respiratory rate of 60 breaths per minute is within the normal range of 30 to 60 breaths per minute for newborns345. A high or low respiratory rate can indicate respiratory distress or failure in newborns2. The nurse should assess the newborn's breath sounds, chest movements, oxygen saturation, and signs of respiratory distress, such as nasal flaring, grunting, retractions, and cyanosis2.
Choice D reason:
Risk for infection is not the priority area for this newborn because there is no evidence of infection in the vital signs or the question stem. However, newborns are vulnerable to infection due to their immature immune systems and exposure to pathogens during birth and aftercare2. The nurse should follow infection control measures, such as hand hygiene, aseptic technique, and cord care, and educate the parents on how to prevent infection at home2.
Correct Answer is C
Explanation
Choice A reason:
While positioning is important for comfort during labor, addressing the immediate urge to push takes priority. Panting during contractions is the appropriate action.
Choice B reason:
Although observing for crowning is important when the client is close to delivery, the nurse should first intervene to address the client's urge to push since the client is only 7 cm dilated.
Choice C reason:
When a laboring client feels the urge to push but is not yet fully dilated (10 cm), encouraging her to pant can help reduce the urge to push and avoid complications, such as cervical swelling or tearing. This breathing technique helps the client delay pushing until full dilation and readiness of the cervix.
Choice D reason:
Assisting the client to the bathroom would not be appropriate at this stage of labor because the urge to push could lead to unsafe delivery outside the appropriate setting, and movement could increase discomfort or risks.
