DNA replication is semiconservative, which allows each of the 2 strands to serve as a template for the new strands - ANSWER - true Recall that the DNA polymerase must bind a double-stranded polymer before it can start making its own DNA polymer. What helps the DNA polymerase to overcome this problem in DNA replication? - ANSWER - RNA primers Several components of cigarette smoke, including benzopyrene, insert themselves into the DNA and lead to several types of mutations such as frameshift...

Which level of protein structure is disrupted through the hydrolysis of peptide bonds? Quaternary Tertiary Primary Secondary - ANSWER - Primary The primary structure of a protein is the sequence of amino acids held together by peptide bonds. Peptide bonds are formed by dehydration reactions and disrupted by hydrolysis. A mutation in the beta-hemoglobin gene, which results in the replacement of the amino acid glutamate in position 6 with the amino acid valine, leads to the devel...

what is the key to high performance trauma team? - ANSWER - effective communication skilled communication, cooperation and coordination are the cornerstones of high-performance teams and high-quality trauma care when obtaining a history for an injured patient, understanding the kinematic concepts associated with the mechanism of injury and energy transfer can initially assist the trauma provider in what? - ANSWER - evaluating and anticipating the types of injury that may be present MOI an...

What is the key to a high performing trauma team? - ANSWER - effective communication rationale: skilled communication, cooperation, and coordination are the cornerstones of high-performance teams and high-quality trauma care When obtaining a history for an injured patient, understanding the kinematic concepts associated with the mechanism of injury and energy transfer can initially assist the trauma provider in: - ANSWER - evaluating and anticipating the types of injuries that may be prese...

Expedite transfer to the closest trauma center - ANSWER - A 56 y/o M involved in a MVC is brought to the ED. He complains of neck pain, SOB, and diffuse abdominal pain. His GCS is 15, VS: BP 98/71, HR 125, RR 26, SpO2 94% on high-flow O2 via NRB mask. Which is the priority intervention for this patient? a pertinent medical hx is crucial - ANSWER - Which of the following considerations is the most important when caring for a geriatric trauma pt? Mitigation - ANSWER - Following a review of r...

Primary concern when a person cannot stop coughing/clearing their throat following house fire/smoke? - ANSWER - Airway/Intubate Lab evidence of cellular perfusion - ANSWER - Base Excess (Less than -6 is BAD) Multiple people are in the ER of different ages who all go to the same church. They all have the same symptoms. What is the most likely cause? - ANSWER - Biologic Suspected shock type with a spinal cord injury - ANSWER - Distributive Shock (Includes neurogenic) Patient has GCS of...

All of these are considered a critical communication point in trauma care EXCEPT which of the following? - ANSWER - Defusings A defusing is part of critical incident stress management but is not considered a critical communication point in trauma care. .During the primary survey of an unconscious patient with multi-system trauma, the nurse notes snoring respirations. What priority nursing intervention should be performed next? - ANSWER - Insert an oropharyngeal airway if there is no gag refle...

What is kinematics? - ANSWER - A branch of mechanics (energy transfer) that refers to motion and does not consider the concepts of force and mass of the object or body. What is Newton's First Law? - ANSWER - A body at rest will remain at rest. A body in motion will remain in motion until acted on by an outside force. What is the Law of Conservation of Energy? - ANSWER - Energy can neither be created nor destroyed. It is only changed from one form to another. What is Newton's Second La...

EMS brings a patient who fell while riding his bicycle. Using the American College of Surgeons screening guidelines, which assessment finding would prompt the nurse to prepare the patient for radiologic spine clearance? - ANSWER - Alert with no neurological deficits The trauma nurse knows that placing a bariatric patient in a "ramped position" provides better visualization during the insertion of which device? - ANSWER - Endotracheal tube A 35-year-old male presents with facial trauma af...

What is the best measure of the adequacy of cellular perfusion and helps predict the outcome of resuscitation? - ANSWER - Base deficit used in conjunction with serum lactate Will hypocapnia cause vasoconstriction or vasodilation, especially in the cerebral vasculature? - ANSWER - Vasoconstriction What results from tissue hypo perfusion and oxygen deficit? - ANSWER - Metabolic acidosis What type of shock results in generalized vasodilation? - ANSWER - Neurogenic shock Spinal cord inju...

The trauma nurse knows that placing a bariatric patient in a "ramped position" provides better visualization during the insertion of which device? - ANSWER - endotracheal tube Tearing of the bridging veins is most frequently associated with which brain injury? - ANSWER - subdural hematoma A patient is found lying on the floor after falling 13 hours ago. Which of the following laboratory values is expected with a musculoskeletal complication associated with this presentation? - ANSWER - E...

1. Preparation and Triage 2. Primary Survery (ABCDE) with resuscitation adjuncts (F,G) 3. Reevaluation (consideration of transfer) 4. Secondary Survey (HI) with reevaluation adjuncts 5. Reevaluation and post resuscitation care 6. Definitive care of transfer to an appropriate trauma nurse - ANSWER - Initial Assessment 1. A- airway and Alertness with simultaneous cervical spinal stabilization 2. B- breathing and Ventilation 3. circulation and control of hemorrhage 4. D - disability (ne...

What are the greatest risks for transport? - ANSWER - Loss of airway patency, displaced obstructive tubes lines or catheters, dislodge splinting devices, need to replace or reinforce dressings, deterioration in patient status change in vital signs or level of consciousness, injury to the patient and/or team members According to newtons law which of these two force is greater: size or force? - ANSWER - Neither. For each force there is an equal and opposite reaction. What is the relationship...

Why is a measure of serum lactate obtained in the initial assessment of the trauma patient? Answer: c - ANSWER - a) to measure oxygenation and ventilation b) to quantify the base deficit for the adequacy of cellular perfusion c) *to gauge end-organ perfusion and tissue hypoxia ** d) to determine the underlying cause of shock A trauma patient is restless and repeatedly asking "where am I?" vital signs upon arrival were BP 100/60 mm Hg, HR 96 beats/min, and RR 24 breaths/min. Her skin ...
