What makes a trauma team execute at a high level? - ANSWER proficientdialogue
Justification: Effective communication, teamwork, and coordination are
essential components of high-achieving teams and superior trauma treatment.
Understanding the kinematic concepts related to the mechanism of injury and
energy transfer will help the trauma physician initially when taking the patient's
history: - ANSWER assessing potential injuries and projecting their nature
Rationale: The energy transfer and injury mechanisms can help the provider
assess and predict damage.
In trauma patients, the leading avoidable cause of mortality is: - ANSWER
uncontrollably bleeding
Rationale: Since uncontrolled bleeding is the primary factor contributing to
avoidable deaths following injuries, identifying and addressing it at the early
assessment phase is essential.
During the first evaluation, the across-the-room observation stage offers the
chance to: ANSWER reprioritize circulation before airway or breathing
Rationale: The purpose of the initial across-the-room inspection is to quickly
determine whether or not respiration and/or airway should take a backseat to
circulation. If uncontrollably large external bleeding is detected, this is done.
Which of the following sums up the principles of ventilation connected to a
bag-mask device the best? - ANSWER Breathe out at a rate of 10 to 12 breaths
each minute.
justification: if ventilation is not working, help it by breathing in 10–12 times
per minute or once every 5–6 seconds.
, Which of the following best describes the level of cellular perfusion and is
useful in predicting how well resuscitation will work? - DEBITOR base of
answers
Justification: base deficit is a marker of the appropriateness of cellular perfusion
and, when combined with serum lactate, aids in the prediction of resuciation
success.
What safe pharmaceutical substitute is there for opioids when treating rib
fracture pain in an anticoagulated patient? - Intercostal nerve blocks
(ANSWER)
Justification: long-acting anesthetics are used in continuous intercostal nerve
blocks, which can safely and effectively control pain in patients on
anticoagulants.
Hypocapnia in a patient with a severe traumatic brain injury results in:
ANSWER vasoconstriction of the brain
Justification: hypocapnia, or low carbon dioxide, will result in vasoconstriction,
particularly in the brain and its vascular system.
A patient who sustained a knife wound to the neck is hemodynamically stable
and has an unbroken airway. He laments having trouble speaking and
swallowing. Which of the following is next in line for further evaluation? -
Damage to the spinal cord
rationale: penetrating neck trauma may entail concomitant damage to the spinal
cord, airway, or vascular neck tissues. The second frequent concomitant injury,
with an unharmed airway and hemodynamic stability, is to the spinal cord.
