Cardiology and Resuscitation Study Center > Diagnostic Tests > Cardiology and Resuscitation Step 1 of 41 2% A 22-year-old male who drank antifreeze is found with altered mental status. He is responsive to painful stimuli. He has the following vital signs: HR 116, fast and deep respirations at 48/minute, BP 104/54, and a room air pulse oximeter reading of 97%. Appropriate treatment for this patient would be*to place patient on an automated transport ventilator.to place patient on CPAP at 5 cm H20.positive pressure ventilations with a BVM.application of a nasal cannula at 4 L/min. A 28-year-old female goes into sudden cardiac arrest. Her husband tells you she is 34 weeks pregnant. In order to perform CPR on this patient you should*perform CPR as you would for any adult.perform manual left uterine displacement.place the patient on a backboard and pad under the right side of the board.adjust your hand position to accommodate for the size of the pregnant uterus. The right carotid artery originates from the*internal thoracic artery.brachiocephalic artery.circle of Willis.brachial plexus. 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.remove the pads and properly place them on the chest.skip this round of shocking and resume CPR.hit the shock button.

You should suspect*vaso-occlusive crisis.pulmonary embolism.aortic dissection.right-sided heart failure. When might it be acceptable to consider terminating resuscitative efforts in a pediatric cardiac arrest?*You should never terminate resuscitative efforts in a pediatric arrestOnly when you are more than 60 minutes away from definitive careAfter ten minutes of high quality CPR and resuscitation with no return of spontaneous pulsesOnly when you are too exhausted to continue or the AED ceases to function The goal for SpO2 following ROSC in an adult that suffered a cardiac arrest should be*94 - 99%.exactly 94%.97 - 100%.100%.

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.*sympatheticparasympatheticanticholinergiccholinergic 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.

You should suspect a pneumothorax in this patient because*pediatric ribs are not calcified so they are more brittle than adult ribs.lung lobes do not fuse until puberty.pediatric patients have more lung tissue per kg than adults.pediatric ribs are more pliable than adults and can sustain significant force without breaking. All of the following can result from overly aggressive ventilations with a BVM, EXCEPT*pulmonary embolism formationdecreased blood pressure.pneumothorax.emesis. You are performing CPR on a 2-year-old child. Your AED is for adults and without a pediatric dose attenuator.
