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 - ANS 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 - ANS 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 - ANS 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 - ANS 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 - ANS 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 - ANS c) immediately initiate isolation
precautions
The fact that mult people with different demographics are appearing with similar signs and
symptoms would alear the nurse to a possible biological exposure. These patients should be
placed in isolation to prevent the possible spread and further determination can be made.
What is the most important consideration during the initial assessment when caring for an
older adult who has sustained serious injuries?
a) they are likely to be fearful in the ED
b) medical history including current medications
c) availability of support systems after discharge
d) accessibility to a primary care physician - ANS b) medical history including current
medications
An adult patient involved in a motor vehicle collision is brought to the ED of a rural critical
access facility. They complain of neck pain, shortness of breath, and diffuse abdominal pain.
The Glasgow Coma Scale is 15. Vital signs are BP 98/71, HR 125 bpm, RR 26 bpm, and SpO2 94%
on a high-flow oxygen via non-rebreather mask. Which of the following is the priority
intervention for this patient?
