Document Content and Description Below

Fluid resuscitation is administered to a traumatically injured patient. After resuscitation, the trauma nurse evaluates the patient's response to that resuscitation to determine whether additional... fluids should be administered. Which of the following factors is most likely to impact this evaluation? - CORRECT ANSWER Beta-blockers blunt changes in the pulse and blood pressure. This may both reduce changes associated with recognizing hypovolemia but it can also reduce changes associated with the response to treatment. Many times the blood pressure falls and the pulse rises with hypovolemia and the opposite happens after fluid resuscitation. When the patient is on beta-blockers, these changes may not occur. Although it is more difficult to assess for changes in skin color in dark-skinned individuals, skin changes are generally not used to evaluate the effectiveness of fluid resuscitation and further resuscitation would not be based on changes in skin color. The presence of lower extremity trauma does not influence evaluation of fluid resuscitation nor the need for additional fluids. A body mass index of 21 kg/m2 is within normal limits and is unlikely to affect resuscitation or the evaluation of resuscitation 50% polyethylene glycol will be used as part of the treatment for: - CORRECT ANSWER 50% polyethylene glycol is known to increase the solubility of phenols in water and should be used as part of the decontamination process in patients exposed to phenols. It will have no therapeutic effect for patients with pancreatic trauma, carbon monoxide poisoning (treated with 100% oxygen) or acute respiratory distress syndrome (treated with appropriate ventilator management and prone positioning) A reagent strip that tests for glucose is used in the assessment of a traumatically injured patient. What injury is likely suspected? - CORRECT ANSWER A basilar skull fracture may result in leakage of cerebrospinal fluid, which is rich in glucose. Reagent strips that test for glucose can be used to assist the diagnosis of basilar skull fracture by checking fluid coming from the nose or ears for glucose. A reagent strip that tests for glucose will not be therapeutic in assessing for a bladder rupture, diffuse axonal injury or a ruptured amniotic sac. When administering large volumes of blood products, the trauma nurse should monitor for which of the following findings which could indicate hypocalcemia? - CORRECT ANSWER A classic finding associated with hypocalcemia is QT prolongation. ST elevation is more common with cardiac ischemia and not associated with hypocalcemia. Tall peaked T waves and flattening of the P wave are both associated with hyperkalemia, not hypocalcemia The trauma nurse knows that treat [Show More]
