Describe one fat embolism syndrome is most likely to occur in its characteristics - ANSWith longform fractures. Tachycardia, Thrombocytopenia, and petechiae rash. Describe the characteristics of cardiogenic shock - ANSCardiogenic shock results from pump failure in the presence of adequate intravascular volume.

What are the three processes that transfer oxygen from the air to the lungs and blood stream - ANSVentilation: the active mechanical movement of air into and out of the lungs; diffusion: the passive movement of gases from an area of higher concentration to an area of lower concentration; and perfusion: the movement of blood to and from the lungs as a delivery medium of oxygen to the entire body. What are the three stages of shock - ANSCompensated, decompensated or progressive, and irreversible. What are the treatment goals for a TBI? - ANSO2 saturation > or equal to 95%, systolic blood pressure > or equal to 100 MMHG, ICP < 15 MMHG, CPP > or equal to 60 MMHG, normal glycemia, hemoglobin > or equal to 7 g/DL, sodium 135-145, osmotic diuretics, anti-emetics, sedatives, anticonvulsants, head of bed at 30°, and neck at midline What causes quarternary effects of blast traumas? - ANSAll explosion related injuries, illnesses, or diseases not due to the first three mechanisms. Injuries include external and internal burns, crush injuries, closed and open brain injuries, asthmatic or breathing problems from dust smoke or toxic fumes, angina, or hyper glycemia and hypertension. What causes quinary effects of blasts traumas? - ANSThose associated with exposure to hazardous materials from radioactive, biologic, or chemical components of a blast. Injuries include a variety of health effects depending on agent. What causes the primary effects of blast traumas? - ANSThe direct blast effects. Types of injuries include last long, tympanic membrane rupture and middle ear damage, abdominal hemorrhage and perforation, global rupture, mild Trumatic brain injury. What causes the secondary effects of blast traumas? - ANSProjectiles propelled by the explosion. Injuries include penetrating or blunt injuries or I penetration. What causes the tertiary effects of blast traumas? - ANSResults from individuals being thrown by the blast wind. Injuries include hole or partial body translocation from being TNCC 8TH EDITION EXAM 10 LATEST VERSIONS (VERSION A & B) 2024-2025 COMPLETE 300 QUESTIONS AND CORRECT DETAILED ANSWERS WITH RATIONALES (VERIFIED ANSWERS) |ALREADY GRADED A+VERIFIED thrown against a hard service: blunt or penetrating trauma's, fractures, traumatic amputations. What is a trademark symptom of an epidural hematoma - ANSLoss of consciousness then awake and alert then loss of consciousness What is bending? - ANSLoading about an axis. Bending causes compression on the side the person is bending toward intention to the opposite side What is combined loading? - ANSAny combination of tension compression torsion bending and/or shear. What is compression? - ANSCrushing by squeezing together What is Cullen's sign and its significance? - ANSCullens sign is periumbilical bruising and is indicative of intraperitoneal bleeding What is shearing? - ANSDamage by tearing or bending by exerting faucet different parts in opposite directions at the same time. What is tension? - ANSstretching force by pulling at opposite ends What is the minimum permissive hypertension and a trauma patient? - ANSA systolic of greater than or equal to 90 MMHG What is the minimum permissive oxygenation level of a trauma patient? - ANSGreater than or equal to 94% What is the Munro-Kellie doctrine? - ANSWithin the skull 80% his brain, 10% is blood, and 10% is CSF. Any increase of any of the products results in increased intracranial pressure. What is the recommended fluid bolus for a trauma? - ANS500 ML's of warmed isotonic crystalloid. Ongoing fluid boluses of 500 ML's should be given judiciously with constant reassessments after administration. What is the relationship between mass and velocity to kinetic energy? - ANSKinetic energy is equal to 1/2 the mass multiplied the square of its velocity therefore when mass is doubled so is the net energy, however, when velocity is doubled energy is quadrupled. What is the trauma triad of death? - ANShypothermia, acidosis, coagulopathy What is torsion? - ANSTorsion forces twist ends in opposite directions. TNCC 8TH EDITION EXAM 10 LATEST VERSIONS (VERSION A & B) 2024-2025 COMPLETE 300 QUESTIONS AND CORRECT DETAILED ANSWERS WITH RATIONALES (VERIFIED ANSWERS) |ALREADY GRADED A+VERIFIED When capnography measurement reads greater than 45MMHG, the nurse should consider increasing or decreasing the ventilation rate? - ANSIncreasing the ventilation rate. Doing so would allow the patient to blow off retained CO2. When capnography measurement reads less than 35MMHG, the nurse should consider increasing or decreasing the ventilation rate? - ANSDecreasing the ventilation rate. By doing so, the nurse allows the patient to retain CO2. When would you use a nasopharyngeal airway versus an oral pharyngeal airway? - ANSNasopharyngeal airways is contraindicated in patients with facial trauma or a suspected basilar skull fracture. Oral pharyngeal airways is used in unresponsive patients unable to maintain their airway, without a gag reflex as a temporary measure to facilitate ventilation with a bag mask device or spontaneous ventilation until the patient can be intubated. According to newtons law which of these two force is greater: size or force? - ANSNeither. For each force there is an equal and opposite reaction. Define Cushing's triad - ANSBradycardia, progressive hypertension (widening pulse pressure), and decreased respiratory effort Define the characteristics of neurogenic shock - ANSDistributive shock with a T6 or higher injury results and vasodilation, bradycardia, flushed warm dry skin. Risk for temperature instability. Nursing interventions include maintaining warmth and spinal stabilization. Define the characteristics of spinal shock - ANSTransient loss of function can include loss of reflexes and muscle tone below the level of industry with possible vascular response. Describe one fat embolism syndrome is most likely to occur in its characteristics - ANSWith longform fractures. Tachycardia, Thrombocytopenia, and petechiae rash. Describe the characteristics of cardiogenic shock - ANSCardiogenic shock results from pump failure in the presence of adequate intravascular volume. Lack of cardiac output and an organ perfusion occurs secondary to a decrease in myocardial contractility and or valvular insufficiency. This can happen with blunt cardiac trauma or an MI. Symptoms can include low blood pressure increase heart rate and respiratory rate chest pain shortness of breath dysrhythmias increase troponin and pale cool moist skin Describe the characteristics of distributive shock. - ANSDistributive shock occurs as a result of Mel distribution of an adequate circulating blood volume with the loss of vascular tone or increased permeability. This can occur with spinal cord injuries, sepsis, or anaphylaxis. Symptoms include low blood pressure heart rate respiratory rate preload and afterload, spinal tenderness, difficulty breathing, warm pink and dry skin with a cool core temperature.
