Preparation Flashcard 2

A. Rationale: The stylet is inserted into the endotracheal tube prior to intubation. It preserves the tube’s shape so that it does not bend or kink while being inserted.

D. Rationale: Fetal gas exchange relies on placental respiration. Physiologic parameters that can be used to evaluate for respiratory failure include a loss of heart rate variability, heart rate decelerations, and depressed fetal activity.

C. Rationale: A CO₂ detector changes color from purple to yellow in the presence of CO₂. When CO₂ is detected, there is gas exchange present where O2 is absorbed from the alveoli and CO₂ is expelled from the pulmonary circulation.

B. Rationale: To warm a preterm newly born at < 32 weeks gestation, the following equipment is needed: plastic wrap, thermal mattress, hat, temperature sensor, and sensor cover for prolonged resuscitation, warm towels or blankets, and a preheated warmer.

C. Rationale: The flow-inflating bag (anesthesia bag) only fills up in the presence of a compressed gas source. Without it, the bag will deflate.

B. Rationale: Required for endotracheal intubation is a laryngoscope that comes with a handle and differently sized blades used to push the tongue anteriorly so that the larynx is visualized. The endotracheal tube is then inserted through the larynx.

D. Rationale: The laryngeal mask is designed so that no other instrument is necessary for insertion. The side with the laryngeal mask is inserted against the hard palate until a resistance is felt. It is then inflated to hold it in place. There is no size available for preterm babies.

A. Rationale: The neonatal resuscitation team member must be able to perform the following tasks and acquire the following skills: chest compressions, endotracheal intubation, positive pressure ventilation, and umbilical vein catheterization.

D. Rationale: Plastic wrap, also known as Saran wrap, can be used to keep newly born patients < 32 weeks gestation warm by preventing cooling from evaporation. The plastic wrap also acts as insulation to prevent heat dissipation from the patient’s skin into the ambient temperature air.

D. Rationale: Preventive maintenance is usually performed by the manufacturer to ensure that equipment, such as defibrillators, pulse oximeters, and waveform capnographs, is in good working order.
