An adult pt who sustained a severe head trauma has been
intubated and is 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
d) increase the amount of oxygen delivered - correct answer
✅✅a) decrease the rate of manual ventilation
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 - correct answer ✅✅d) continue to ICU

Caregivers carry a 2-year old into the ED who fell out of 2nd story
window. The patient is awake and crying with increased work of
breathing and pale skin. which of the following interventions has
the highest priority?
a) stabilizing the cervical spine
b) applying a nonrebreather mask
c) establishing IV access
d) preparing for drug-assisted intubation - correct answer
✅✅a) stabilizing the cervical spine
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?
a) diagnostic peritoneal lavage
b) angiography
c) non-contrast abdominal CT
d) serial abdominal assessments - correct answer ✅✅d) serial
abdominal assessments
The FAST exam is done at the bedside to identify pathological
fluid in the abdominal and pelvic cavities and reduces the need

for more invasive testing. However, a negative FAST exam does
not rule out injury, so serial abdominal assessments should occur.
If a CT scan is indicated, it should be done with contrast
A patient arrives with a 3-inch laceration to their forearm from a
tree branch. Which of the following methods will the nurse use to
remove small pieces of bark and debris from the wound?
a) low pressure irrigation
b) high pressure irrigation
c) scrubbing with normal saline
d) scrubbing with tap water - correct answer ✅✅b) high
pressure irrigation
low pressure irrigation used for larger wounds
Three adults present at different times during a one-hour period
with high fever, fatigue, and headache. All three patients have a
rash which started on their mouth, face, and arms with
progression to the chest and abdomen. They all visited the same
grocery store within the last week. What is the most appropriate
intervention from the triage of these patients?
a) move them to a decontamination area
b) mask the patients and send them to the waiting room
c) immediately initiate isolation precautions
d) send them to the waiting room without a mask - correct
answer ✅✅c) immediately initiate isolation precautions
