A 19-year-old male presents with severe difficulty in breathing. He tells you, with one word dyspnea, that he has taken his inhaled steroids and used his rescuer inhaler multiple times without any relief. He has accessory muscle use, diffuse wheezing in all lung fields and the following vital signs: Respiratory rate of 44, SpO2 of 84% on room air and his heart rate is 112/min. This is known as*asthmatic crisis.ARDS (acute respiratory distress syndrome).unstable asthma.status asthmaticus. The right carotid artery originates from the*internal thoracic artery.circle of Willis.brachiocephalic artery.brachial plexus. You are transporting a 56-year-old male who is complaining of chest pain. You are 12 minutes from the hospital when suddenly the patient becomes unresponsive, pulseless and apneic. You should*upgrade to emergent response.contact advanced life support.pull the ambulance to the side of the road, attach the AED and begin CPR.attach the AED and perform CPR. Aspirin is given to a patient experiencing signs and symptoms of a possible myocardial infarction because it*dissolves blood clots in the coronary arteries.dilates coronary arteries.prevents clots from growing any larger.is an analgesic. A 77 year old male with a significant cardiac history complains of weakness, fatigue and chest pressure with a sudden onset. His skin is pale, cool and diaphoretic and his vital signs are P 122, R 36, and BP 76/44. You auscultate bilateral coarse crackles. You should suspect the most likely cause is*cardiogenic shock.unstable angina.ruptured abdominal aortic aneurysm.cor pulmanale. A 66-year-old female is on bed rest for a deep vein thrombosis (DVT) in her leg when she requests to be transported to the ER for pain management. You gently move this patient because you know that if the clot becomes dislodged from her calf it could migrate to her*pulmonary artery.femoral artery.coronary artery.carotid artery. All of the following can result from overly aggressive ventilations with a BVM, EXCEPT*emesis.decreased blood pressure.pulmonary embolism formationpneumothorax.

A 66-year-old male presents with a BP of 101/30 and complains of chest pain. He states he normally has hypertension and runs around 150/100. The most concerning thing about this BP is*it could be indicative of a pericardial tamponade.a pulse pressure of 71 mmHg.coronary arteries are perfused during diastole.pulmonary perfusion pressures are compromised. Jugular venous distention often results from fluid overload or compromise of the*aortic valve.renal arteries.right ventricle.left atrium. You are a lone rescuer performing CPR on a 3-year-old when a second trained rescuer arrives on scene. You should perform CPR using the ratio*30 compressions: 2 breaths.200 compressions: 8-10 breaths.3 compressions: 1 breath.15 compressions: 2 breaths. You arrive on scene of an unresponsive, apneic 2 week-old male. A weak pulse at a rate of 48/minute is palpated. The most appropriate treatment for this patient would be to*warm, dry and oxygenate the patient.provide rescue breaths at a rate of 20/minute.provide rescue breaths at a rate of 8-10/minute.start CPR with a ratio of 30:2. A 32-year-old female has a pulmonary embolism and complains of severe shortness of breath and difficulty in breathing. This represents a problem with*increased alveolar pressure.ventilation.perfusion.the pulmonary valve. You have attached an AED that uses a biphasic current and performed CPR on the patient; the AED now says shock advised. You have your finger on the shock button when you notice that the pads are reversed and the pad that goes on the right side is on the left and vice versa. You should*unplug the connector, flip it over and plug it back in.skip this round of shocking and resume CPR.hit the shock button.remove the pads and properly place them on the chest. A 65-year-old male with a history of myocardial infarction and COPD complains of progressively worsening shortness of breath. Auscultation reveals greatly diminished lung sounds on the right side. During the physical exam you notice subcutaneous emphysema around the right clavicle. You should suspect*dynamic hyperinflation syndrome.tracheal-bronchial disruption.pleural effusion.spontaneous pneumothorax. A 73-year-old male complains of chest pain and has taken two of his nitroglycerin tablets in the past 10 minutes with no relief. His vital signs are HR 128, BP 111/72, and R 20. He takes no other medications and has no allergies to medications. You should*help him administer his nitroglycerin and withhold aspirin.administer 325 mg of aspirin and withhold nitroglycerin at this time.obtain additional history before proceeding.administer 325 mg of aspirin and help him to administer his nitroglycerin. The goal for SpO2 following ROSC in an adult that suffered a cardiac arrest should be*100%.94 - 99%.exactly 94%.97 - 100%.

On top of a 9,000 foot summit the oxygen content of the atmosphere is*17%16%11%21% A 56-year-old male firefighter emerges from a structure fire with complaints of worsening shortness of breath and weakness. He states he inhaled smoke. A physical exam reveals bright “cherry” red skin. Your portable carbon monoxide detector reads 0ppm. You place him on a NRB at 15 L/min and achieve an SpO2 of 100% but he still complains of worsening SOB. You should suspect*pulmonary embolism.nitrogen narcosis.cyanide toxicity.carbon dioxide poisoning. After helping a patient to properly administer their epinephrine pen you notice their heart rate increases from 86 beats per minute to 118 beats per minute. This is likely from the _______ nervous system effects of epinephrine.*cholinergicanticholinergicparasympatheticsympathetic In which of the following patients is positive pressure ventilations with a BVM indicated?*2-year-old male with pneumonia, respiratory rate 30/minute, tidal volume 100ml16-year-old male with diabetic ketoacidosis, respiratory rate 42/min, tidal volume 490ml41-year-old male with chest pain, respiratory rate 24/minute, tidal volume 520ml88-year-old female with an active stroke, respiratory rate 14/minute, tidal volume 85ml You witness a 6-year-old male collapses suddenly while playing basketball.

He may be suffering from any one of the following EXCEPT*stable angina.myocardial infarction.unstable angina.acute coronary syndrome. A 68-year-old male presents with chest pain that radiates through to his back. When obtaining vital signs you note the blood pressure on the right arm is 118/56 and the left arm is 152/90. You should suspect*pulmonary embolism.right-sided heart failure.aortic dissection.vaso-occlusive crisis. You are a lone rescuer responding to a pulseless, apneic 8 month-old. Your first action should be to*go and get an AED.call for additional resources (Advanced Life Support).perform 2 minutes of CPR.perform one cycle of 30:2 and then go get the AED.

You attach the AED to his chest and then realize you are standing on the same metal surface that the patient is on. You should*place a non-conductive item such as a blanket under the patient before defibrillating.defibrillate as normal.move the patient to a different surface.ensure that the patient is in contact with an electrical grounding device.

A 62-year-old male with a history of CHF complains of fatigue, shortness of breath, and has had to sleep sitting upright for the past two nights. Auscultation of the lungs reveals fine crackles in both bases. He is most likely suffering from*right-sided heart failure.respiratory failure.left-sided heart failure.aortic stenosis. A 6-year-old patient was involved in a car vs bicycle accident. He complains of chest pain and severe difficulty breathing. Physical exam does not reveal any rib fractures, crepitus or a flail segment. You should suspect a pneumothorax in this patient because*lung lobes do not fuse until puberty.pediatric ribs are more pliable than adults and can sustain significant force without breaking.pediatric patients have more lung tissue per kg than adults.pediatric ribs are not calcified so they are more brittle than adult ribs.
