NREMT: Missing Questions Exam 22 Questions And Answers

In relation to the eye, which of the following is the easiest for a pathological process to disrupt? - ANS Refractive strength You have been called for a 3 kg baby who was delivered just before your arrival. After his airway has been suctioned and tactile stimulation has been provided, he still isn't breathing on his own. At what rate would you ventilate this neonate? - ANS 30-60 breaths per minute A hockey player is involved in a high speed collision with a teammate. He falls to the floor holding his chest, complaining of sharp and localized pain. The team physician suspects a simple fracture of a bone within the chest. Assuming the absence of further internal injury, what bone is most likely to be fractured in this patient. - ANS The eighth rib The 4th through 9th ribs are the most commonly fractured in all forms of trauma, due to their relative immobility compared to the lower ribs. This is due to their direct connection to the sternum (minimal intervening cartilage). Fractures of these ribs are commonly associated with pneumothorax and hemothorax, with rare involvement of the spleen/liver/kidneys. All other options presented here are usually the result of high energy trauma. While sports injuries can indeed be high energy, the lack of any further internal damage argues against the possibility in this case. In children greater than 12 months, the most common causes of rectal bleeding are: - ANS Infectious gastroenteritis and anal fissures In children greater than 12 months, the most common causes of rectal bleeding are infectious gastroenteritis and anal fissures. The gastroenteritis will cause melena (tarry stool) and anal fissures will cause hematochezia (bright red blood). Your patient was involved in a motor vehicle collision (MVC) less than 24 hours ago and awoke this morning with a severe headache, blurred vision, and 2 black eyes. He denies directly hitting his face but states he was an unrestrained front seat passenger. The findings lead you to suspect a basilar skull fracture. Which of the following would cause the patient's eyes to blacken overnight? - ANS Bleeding from the posterior auricular artery Battle signs or mastoid ecchymosis is a good indication of a basilar skull fracture. It directly results in blood extravasation along the normal pathway of the posterior auricular artery. Overinflation of the pilot balloon on ET tube while a patient is intubated can cause: - ANS ischemia of the tracheal wall Excessive pressure to delicate tissue of the lower airway can reduce blood flow causing ischemia via compression of the superficial cell layers. You are dispatched to a pregnant patient who is experiencing contractions. Upon assessment, you decide that delivery is imminent. As she pushes, you notice a prolapsed cord protruding inferior to the head. The cord is NOT pulsating. Which of the following is the BEST procedure to correct this situation? - ANS Placed a gloved hand into the vagina and lift the baby's head up until you feel the cord pulsate You should relieve the pressure of the baby's head that is occluding blood flow through the cord. Make sure blood is flowing and rapidly transport the patient to the hospital. In a stable (non-transport) scenario, putting her into the knee-chest position would allow you to partner with gravity. Your deciding that delivery is imminent is a hunch often proven wrong by a few minutes, so every second you wait to "deliver normally" may be causing ischemic damage. You never cut the cord until the baby is delivered. Sliding the cord will be based on what? Which way do you slide it? You could add a twist and make things worse. Cerebral blood flow in a child is how much faster in volume than in an adult? - ANS Twice as fast The pediatric brain requires nearly twice the cerebral blood flow as an adult brain. If an ET tube that has been inserted with good visibility goes too far, it is prone to enter which of the following structures? - ANS Right mainstem bronchus Because of the anatomical appearance of the trachea, it is most common for an ET tube that has been inserted too far to enter the right mainstem bronchus. All of the following are visual or auditory clues to diaphragmatic hernia EXCEPT - ANS Umbilical hernia
