Metabolic acidosis T/F: Uterine resting tone may appear higher (25 to 40 mmHg) during amnioinfusion. B. Administration of tocolytics One of the important characteristics of fetal development is that, with the decrease in oxygen supply, the blood flow of other organs is rapidly redistributed to the brain and heart, increasing by 90 and 240%, respectively, a response that is similar in both preterm and near-term fetuses (Richardson et al., 1996).

No decelerations were noted with the two contractions that occurred over 10 minutes. Give the woman oxygen by facemask at 8-10 L/min This is because the mother (the placenta) is doing the work that the baby's lungs will do after birth. An inadequate amount of oxygen occurring before birth, during delivery, or immediately after birth can cause serious birth injuries and affect fetal brain development.

B. B. The correct nursing response is to: Late decelerations There are sub-categories of preterm birth, based on gestational age: moderate to late preterm (32 to 37 weeks). B. The rationale of fetal heart rate monitoring in this cohort is to monitor the fetus in labour with an aim to identify intrapartum hypoxia and intervene if required. Preterm fetal lambs received either normal oxygen delivery (n = 9, 23 1 ml/kg/min, 24 2 days) or subphysiologic oxygen delivery (n = 7 . 243249, 1982. If hypoxic or mechanical insults persist for a longer period, then the fetus utilizes its adrenal gland to cope with this ongoing stress, leading to a stress response This stress response that occurs through the release of catecholamines from the adrenal glands and represents a physiological mechanism for coping with mechanical or hypoxic insults of labour may not be fully operational in a preterm baby. Which of the following interventions would be most appropriate?
