Chapter 40 & 41 Flashcards
Which of the following interventions is emphasized the most in all AHA guidelines for emergency cardiac care since 2005?
A) Abdominal thrust
B) Defibrillation
C) Chest Compressions
D) Epinephrine
C) Chest Compressions
The paramedic should consider extending the resuscitation effort of a patient with refectory cardiac arrest if:
A) patient remains in PEA
B) patient shows signs of profound hypoxia
C) patient has fixed and dilated pupils
D) return of spontaneous circulation of any duration occurred
D) return of spontaneous circulation of any duration occurred
Your partner returns with an AED as you are performing CPR on a 5 y/0 child. As he opens the AED, he tells you that there are no pediatric pads. You should:
A) instruct him to apply the pads as you continue one-rescuer CPR
B) administer 2mg of adrenaline IM
C) perform defibrillation using adult pads directly on the child’s chest
D) stop CPR and wait for pediatric pads to arrive
A) instruct him to apply the pads as you continue one-rescuer CPR
Your assessment of a 68 y/o female reveals an organized cardiac rhythm at a rate of 80 bpm and an absent carotid pulse. Treatment for this patient may include:
A) dopamine
B) atropine
C) cardiomyopathy
D) epinephrine
D) epinephrine
After determining that an unresponsive adult patient is not breathing, you should:
A) begin CPR immediately without checking for a pulse
B) perform a head-to-toe assessment on the patient
C) administer oxygen through a non-rebreather mask
D) assess for a carotid pulse for no longer than 10 seconds
D) assess for a carotid pulse for no longer than 10 seconds
Defibrillation of a patient who is in asystole is detrimental to the patient because it:
A) reduces the risk of further cardiac complications
B) causes an unnecessary interruption in chest compressions
C) increases the likelihood of spontaneous breathing
D) improves the chances of restoring a normal heart rhythm
B) causes an unnecessary interruption in chest compressions
How does CPR change after an advanced airway device is inserted?
A) chest compressions should be increased in rate
B) chest compressions should be paused during ventilations
C) ventilations should be asynchronous with chest compressions
D) ventilations should be delivered after every 10 compressions
C) ventilations should be asynchronous with chest compressions
Which of the following interventions is emphasized the most in all AHA guidelines for emergency cardiac care since 2005?
A) Epinephrine
B) Defibrillation
C) Abdominal thrusts
D) Chest compressions
D) Chest compressions
What is the current recommendation for the use of epinephrine for patients with ventricular fibrillation or pulseless ventricular tachycardia?
A) Epi should be administered after the second shock
B) Epi should be administered intranasally
C) Epi should not be given in the first 10 minutes
D) Epi should be administered only is the patient is conscious
A) Epi should be administered after the second shock
In addition to high-quality CPR, which of the following interventions has clearly made a positive and measurable difference in survival from sudden cardiac arrest?
A) Cardioversion
B) Epinephrine
C) Chest compressions
D) Defibrillation
D) Defibrillation
What is a disadvantage of using a crystalloid solution when treating a patient with hemorrhagic shock?
They do not have oxygen-carrying capacity
A patient with severe dehydration is found to be hypotensive during your assessment. The most important intervention is this case is:
Transport with fluid resuscitation en route
If the left ventricle fills with 85mL of blood and ejects 60 mL during a contraction, what is the ejection fraction?
70%
What of the following assessment findings should increase your index of suspicion for obstructive shock?
Jugular venous distention
What is an injury or condition would cause obstructive shock?
Cardiac tamponade
Which of the following clinical signs would differentiate septic shock from hypovolemic shock?
Warm or hot skin
By which of the following mechanisms do patients with septic shock become hypovolemic?
Fluid leakage out of the vascular space
Relative bradycardia during neurogenic shock occurs because:
the sympathetic system is not stimulated to release catecholamines
Anaerobic metabolism is the process in which:
inefficient cellular metabolism produces lactic acid
During anaerobic metabolism, the precapillary sphincters relax in response to which of the following?
Lactic acid buildup
A young woman experiences a sudden nervous system reaction that produces temporary, generalized vasodilation and causes her to faint. This is most descriptive of which type of shock?
Psychogenic
Baroreceptors function by:
sensing decreased blood flow and activating the vasomotor center
Which of the following hemodynamic decreases, regardless of the etiology of the shock?
Mean arterial pressure
