TNCC 8th Edition Questions With 100% Verified Solutions What causes the tertiary effects of blast traumas? - ANSWER Results from individuals being thrown by the blast wind. Injuries include hole or partial body translocation from being thrown against a hard service: blunt or penetrating trauma's, fractures, traumatic amputations. What causes quarternary effects of blast traumas? - ANSWER All 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? - ANSWER Those 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 are the three processes that transfer oxygen from the air to the lungs and blood stream - ANSWER Ventilation: 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. When would you use a nasopharyngeal airway versus an oral pharyngeal airway? - ANSWER Nasopharyngeal 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. Describe the measurement of an NPA - ANSWER Measure from the tip of the patient's nose to the tip of the patients earlobe. Measurement of an OPA - ANSWER Place the proximal end or flange of the airway adjunct at the corner of the mouth to the tip of the mandibular angle. True or false: NPAs and OPAs are definitive airways. - ANSWER False. When placing one of these? One should consider the potential need for a definitive airway. Name the three ways to confirm ETT placement - ANSWER Placement of a CO2 monitoring device, Assessing for equal chest rise and fall, and listening at the epigastrium and four lung fields for equal breath sounds. When capnography measurement reads greater than 45MMHG, the nurse should consider increasing or decreasing the ventilation rate? - ANSWER Increasing 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? - ANSWER Decreasing the ventilation rate. By doing so, the nurse allows the patient to retain CO2. What are the three stages of shock - ANSWER Compensated, decompensated or progressive, and irreversible. What are the signs of compensated shock? - ANSWER Anxiety, confusion, restlessness, increased respiratory rate, narrowing pulse pressure were diastolic increases yet systolic remains unchanged, tachycardia with bounding pulses, and decreased urinary output What are the signs and symptoms of decompensated shock? - ANSWER Decreased level of consciousness, hypertension, narrow pulse pressure, tachycardia with weak pulses, tachypnea, skin that is cool clammy and cyanotic, base access outside the normal range, and serum lactate levels greater than two to 4MMOL/L. What are the signs and symptoms of irreversible shock? - ANSWER Obtunded stuporous or comatose state, marked hypertension and heart failure, bradycardia with possible dysrhythmias, decreased and shallow respiratory rate, pale cool and clammy skin, kidney liver and other organ failure, severe acidosis, elevated lactic acid levels, worsening base access on ABGs, coagulopathies with petechiae purpura or bleeding. What are the four types of shock? - ANSWER Hypovolemic, Cardiogenic, Obstructive, & Distributive What is the trauma triad of death? - ANSWER hypothermia, acidosis, coagulopathy Describe the characteristics of obstructive shock - ANSWER Obstructive shock is it mechanical problem that results from hypoperfusion of the tissue due to an obstruction in either the vasculature or the heart resulting in decreased cardiac output.
