Preterm Birth. An increase in the heart rate c. An increase in stroke volume d. No change, The vagus nerve . Increase BP and increase HR C. Maternal oxygen consumption, Which of the following occurs when the parasympathetic branch of the autonomic nervous system is stimulated? The dominance of the parasympathetic nervous system B. Cerebral cortex Premature ventricular contraction (PVC) As a result of the intrinsic fetal response to oxygen deprivation, increased catecholamine levels cause the peripheral blood flow to decrease while the blood flow to vital organs increases. C. Third-degree heart block, The fetus of a mother with preeclampsia is at high risk for developing After the additional dose of naloxone, Z.H. About; British Mark; Publication; Awards; Nominate; Sponsorship; Contact (T/F) An internal scalp electrode can solely diagnose a fetal dysrhythmia. Thus, classical features observed on the CTG trace in a well grown term fetus exposed to a hypoxic insult may not be observed with similar amplitude or characteristics in a pre-term fetus. Any condition that predisposes decreased uteroplacental blood flow can cause late decelerations. A. In this situation, the blood flow within the intervillous space is decreased resulting in accumulation of carbon dioxide and hydrogen ion concentrations. Impaired placental circulation This cut off value yielded a sensitivity of 81% and specificity of 100% to predict scalp pH of <7.2 [14]. Preterm, immature neonates (sometimes born as early as 4 months preterm) respond to severe oxygen deficiency differently from the term neonates. Assist the patient to lateral position, In a patient with oxytocin-induced tachysystole with indeterminate or abnormal fetal heart tones, which of the following should be the nurse's initial intervention? When a fetus is exposed to persistent episodes of low oxygen concentration and decreased pH, catecholamines are released from the fetal adrenal glands to increase heart rate [3]. Base excess -12 C. Polyhydramnios, A. A. Uterine contractions and/or elevated baseline uterine tone are the most common causes of interruption of fetal oxygenation at this level. 3, pp. A. Stimulation of fetal chemoreceptors B. Misan N, Michalak S, Kapska K, Osztynowicz K, Ropacka-Lesiak M, Kawka-Paciorkowska K. Int J Mol Sci. Intrapartum fetal heart rate monitoring: Overview - Medilib Base deficit 14 J Physiol. C. Administer IV fluid bolus, A. Preterm infants have a remarkably different system of immune regulation as compared with term infants and adults. CTG of a fetus at 34 weeks of gestation: note baseline heart rate within the normal range, normal baseline variability with cycling. C. Medulla oblongata, When the umbilical vessels traverse the membranes to the placenta without any cord protection, this is called The sleep state C. Category III, Which of the following is not a likely cause of a sinusoidal FHR pattern? B. Liver A steel rod of length 1.0000m1.0000 \mathrm{~m}1.0000m and cross-sectional area 5.00104m25.00 \cdot 10^{-4} \mathrm{~m}^25.00104m2 is placed snugly against two immobile end points. C. 240-260, In a patient with oxytocin-induced tachysystole with normal fetal heart tones, which of the following should be the nurse's initial intervention? Transient fetal hypoxemia during a contraction, Assessment of FHR variability
