Explanation:
A lack of catecholamine release prevents tachycardia, pallor, and sweating. Instead, vasodilation will cause decreased blood pressure, the heart rate will remain normal, or slow and the skin will remain pink, warm, and dry.
Explanation:
Mild hemorrhage from the nose after insertion of the airway is not an indication to remove it. In fact, it is probably better to keep an NPA in place so as not to disturb the clot or reactivate the bleeding
Explanation:
When immediate interventions are needed, delegate them to your team members while you continue the assessment. This is an important concept that immediately addresses problems encountered and yet does not interrupt the assessment sequence and does not increase scene time. Teamwork is essential to good patient outcomes.
Explanation:
A carbon dioxide level below 35 mmHg indicates hyperventilation.
Explanation:
Bruising of the heart is basically the same injury as an acute myocardial infarction.
Explanation:
The development of decreased lung compliance (difficulty in squeezing the bag-mask device) in the intubated patient should always alert you to the possibility of a tension pneumothorax.
Explanation:
The sudden increase in acceleration produces posterior displacement of the occupants and possible hyperextension of the cervical spine if the headrest is not properly adjusted. The potential for cervical spine injuries is great.
Explanation:
This team approach makes the most efficient use of time and allows you to rapidly perform the initial assessment without becoming distracted by performing the necessary interventions yourself, which can interrupt your thought process and cause errors.
Explanation:
When the ICP increases, the systemic blood pressure increases to try to preserve blood flow to the brain. The body senses the rise in systemic blood pressure, and this triggers a drop in the pulse rate as the body tries to lower the systemic blood pressure
Explanation:
Certain mechanisms of trauma can overcome the protective properties, injuring the spinal column and cord. The most common mechanisms are hyperextension, hyperflexion, compression, and rotation. Less commonly, lateral stress or distraction will injure the cord.
Explanation:
It is important to remember that blood pressure requires a “steady state” activity of all the preceding factors. The heart must be pumping, the blood volume must be adequate, the blood vessels must be intact, and the lungs must be oxygenating the blood.
