Question: 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
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
Question: 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
fluctuation of the water seal chamber during insp and expr is a normal finding
Question: 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
Answer: a) stabilizing the cervical spine
, Question: 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
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
Question: 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
Answer: b) high pressure irrigation
low pressure irrigation used for larger wounds
Question: 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
Answer: 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.
