CORRECT DETAILED
ANSWERS
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 Answers: 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 Answers: d) continue to ICU
fluctuation of the water seal chamber during insp and expr is a normal finding
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 Answers: 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 Answers: 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 Answers: 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
