being manually ventilated via bag-mask device at a rate of 18 bpm. The pt
has received one IV fluid bolus of 500 mL of warm isotonic crystalloid
solution. The PaCO2 is 30 mmHg (4.0 kPa), and the pulse oximetry is 92%.
BP is 142/70 mmHg. What is the most important intervention to manage
the cerebral blood flow?
a) decrease the rate of manual ventilation
b) initiate another fluid bolus
c) recheck endotracheal tube placement

,CO2 is the primary regulator of blood flow to the brain. Aggro manual
ventilation results in decreased PaCO2 levels, which results in
vasoconstriction, which then leads to decreased ICP and inadequate
delivery of O2 and glucose to the brain. Bagging should be at a rate of one
breath every 6 or 10 seconds
A patient with a chest tube transported to the ICU and fluctuation is noted
in the water seal chamber during inspiration and expiration. What is the
best action for the nurse to take?
a) clamp the chest tube
b) return to the ED
c) assist with ventilation via bag-mask device
d) continue to ICU - 🧠 ANSWER ✔✔d) continue to ICU

A retained driver involved in a motor vehicle collision is being brought to the
ED with abdominal, pelvic, and bilateral lower extremity pain. Vital signs
are BP 147/78, HR 98 bpm. A FAST exam is negative for fluid in the
abdominal and peritoneal cavities. Which of the following should the nurse
anticipate?
