ATLS (Advanced Trauma Life Support) Exam –
Complete Verified Answers with Extra Q&A
(Detailed Study Guide, A+ Graded)
Introduction:
This document provides a full set of verified and correct answers to
the ATLS exam, including in-depth explanations of trauma
management principles. It covers pregnancy-related trauma, burns,
frostbite, musculoskeletal trauma, airway management, hemorrhagic
shock, neurogenic shock, head and spinal injuries, and
pediatric/geriatric considerations. In addition to the main exam
material, it contains extra Q&A formatted as a study guide with
clear, concise answers aligned with ATLS protocols.
Exam Questions and Answers
When interpreting x ray films of the pelvis in a pregnant patient,
the symphysis pubis widens 4-8 mm and the sacroiliac joint spaces
increase by the 7th month --- correct answer ---keep this in mind
Eclampsia --- correct answer ---Maintain a high index of suspicion
for eclampsia when seizures are accompanied by HTN, proteinuria,
hyperreflexia, and peripheral edema in pregnant trauma patients.
This can mimic head injury.
External contusions and abrasions of the abdominal wall are signs
of blunt uterine trauma. --- correct answer ---true. Fetal injuries
,can occur when the abdominal wall strikes an object, such as the
dashboard or steering wheel, or when a pregnant patient is struck
by a blunt instrument.
Using a shoulder restraints in conjunction with a lap belt reduces
the likelihood of direct and indirect fetal injury, presumably
because the shoulder belt dissipates deceleration forces over a
great surface area and helps prevent the mother from flexing
forward over the gravid uterus. --- correct answer ---the
deployment of air bags in vehicles does not appear to increase
pregnancy specific risks. Using lap belt alone allows for forward
flexion and uterine compression with possible uterine rupture or
placental abruption. Lap belt worn too high over uterus may
produce uterine rupture.
Penetrating injury to pregnant women --- correct answer ---As
uterus grows larger, other viscera are protected from penetrating
injury. Dense uterine musculature in early pregnancy can absorb
significant amount of energy from penetrating objects decreasing
their velocity and lowering risk of injury to other viscera. However,
fetal outcome is generally poor with penetrating injury to uterus.
carefully observe pregnant patients with even minor injuries since
occasionally minor injuries are associated with placental abruption
and fetal loss. --- correct answer ---True. AND to optimize
outcomes for mother and baby, clinicians must assess and
,resuscitate the mother first and then assess the fetus before
conducting second survey of the mother.
Failure to displace the uterus to the left side in a hypotensive
pregnant patient --- correct answer ---logroll all patients appearing
clinically pregnant (second and third trimester) to the left 15-30
degrees and elevate the right side 4-6 inches and support with a
bolstering device to maintain spinal motion restriction and
decompression of the vena cava.
Due to increases intravascular volume, pregnant patients can lose a
significant amount of blood before tachycardia, hypotension, and
other signs of hypovolemia occur. Thus, what do stable vital signs
in a pregnant patient indicate about the fetus? --- correct answer --
-The fetus may be in distress and the placenta deprived of vital
perfusion while the mother's condition and vital signs appear
stable. Administer crystalloid fluid resuscitation and blood to
support the physiological hypervolemia of pregnancy. vasopressers
should be an absolute last resort in restoring maternal blood
pressure as they further reduce uterine blood flow, resulting in
fetal hypoxia.
What does a normal fibrinogen level indicate in a pregnant patient?
--- correct answer ---Fibrinogen level may double in late pregnancy
and a normal level may indicate early disseminated intravascular
coagulation
, Most common cause of fetal death? --- correct answer ---maternal
shock and maternal death. Placental abruption is second. Placental
abruption is suggested by vaginal bleeding, uterine tenderness,
frequent uterine contractions, uterine tetany, and uterine
irritability (uterus contracts when touched). In 30% of cases of
abruption, bleeding may not occur. Uterine ultrasound may be
helpful in diagnosis, but is NOT definitive.
Signs of uterine rupture --- correct answer ---abdominal
tenderness, guarding, rigidity, or rebound tenderness. Signs of
peritonitis are hard to tell due to expansion and attenuation of the
abdominal wall musculature. Other findings include abdominal fetal
lie (oblique or transverse lie), easy palpation of the fetal parts
because of their extrauterine location and inability to readily
palpate the uterine fundus when there is fundal rupture. Xray
evidence of rupture include extended fetal extremities, abnormal
fetal position, and free intraperitoneal air.
Perform continuous fetal monitoring with a tocodynamometer
beyond 20-24 weeks of gestation. --- correct answer ---Patients
with no risk factors for fetal loss should have continuous
monitoring for 6 hours, whereas, patients with risk factors for fetal
loss or placental abruption should be monitored for 24 hours. RISK
FACTORS ARE: heart rate > 110, an injury severity score >9,
evidence of placental abruption, fetal heart rate >160 or less than
120, ejection during MV, and motorcycle or pedestrian collisions
