Explanation:
Pack the hemostatic agent in the wound and hold firm pressure. The hemostatic agent is an “adjunct” to assist in controlling hemorrhage, not a hemorrhage control by itself.
Explanation:
Although the most reliable method of ensuring proper placement is actually visualizing the tube passing through the glottic opening, even this is not 100% certain. In fact, it is only reliable for the moment you see it. The gold standard for confirming and monitoring ETT placement is waveform capnography.
Explanation:
Give only enough normal saline to maintain a blood pressure high enough for adequate peripheral perfusion. Maintaining peripheral perfusion may be defined as producing a peripheral pulse (such as a radial pulse)
Explanation:
Conditions that can rapidly lead to shock include penetrating wounds to the torso, abnormal chest exam, tender distended abdomen, pelvic instability, and bilateral femur fractures.
Explanation:
The pericardial sac is an inelastic membrane that surrounds the heart. If blood collects rapidly between the heart and pericardium from a cardiac injury, the ventricles of the heart will be compressed, making the heart less able to refill, and cardiac output falls.
Explanation:
This is an example of internal, uncontrolled hemorrhage. Administer sufficient normal saline to maintain peripheral perfusion, following local or EMS agency medical direction policies. Maintaining peripheral perfusion is generally defined as giving enough fluid—usually in boluses—to return a peripheral pulse, such as a radial pulse.
Explanation:
Manipulating the thyroid cartilage can help bring the vocal cords into view during endotracheal intubation. This is called external laryngeal manipulation (ELM). The movement is usually pressing the thyroid cartilage backward against the esophagus and then upward and slightly to the patient’s right side.
Explanation:
Hyperventilation has only a slight effect on brain swelling, but causes a significant decrease in cerebral perfusion from that same vasoconstriction, resulting in cerebral hypoxia. Thus, both hyperventilation and hypoventilation can cause cerebral ischemia and increased mortality in the TBI patient.
Explanation:
Predictors of difficult mask ventilation can be remembered using the “BOOTS” mnemonic:
B – Beards
O – Obesity
O – Older patients
T – Toothlessness
S – Snores or stridor
Explanation:
The purpose of the initial assessment is to prioritize the patient and to identify all immediately life-threatening conditions. The information gathered is used to make decisions about critical interventions and time of transport.
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.
