True False 3. True or False: Therapeutic hypothermia should be considered in the comatose adult after cardiac arrest. o True o False 4. True or False: An individual should be cleared-N prior to a shock only when convenient. True o False 5. True or False: An individual in PEA has an organized cardiac rhythm on ECG. o True oFalse 6. True or False: Transcutaneous pacing should be used on an individual with bradycardia and inadequate perfusion if atropine is ineffective and the individual is exhibiting severe symptoms oTruce oFalse 7. True or False: The time of first response to treatment of an acute stroke may determine the outcome and survival of the individual. o True oFalse 8, True or False: 100% oxygen is acceptable for early intervention but not for extended periods of time. o True oFalse obtain IV access.Explanation / Answer
1 False, a wall of muscles called septum separates the ventricles of the heart. Arota is the artery that begins at the and of left ventricular and it is the largest artery of heart,which pumps blood to the upper and lower parts of the body.
2. True, the most effective treatment for ventricular fibrillation is defibrillation ,as it helps to prevent the choatic rythym and restore normal heart rhythm and blood circulation by doing CPR along with it.In this condition,the patient needs emergency care because it is fatal and the patient does not have pulse. CPR with inbetween defibrillator is used in these conditions.
3.True, therapeutic hypothermia is also known as targeted temperature management or protective hypothermia. It is a treatment in which a specific temperature is maintained for a specific period of time to improve the outcome after a period of blood flow stopped to the brain and other parts of body due to cardiac arrest. It is done to reduce tissue injury due to lack of blood flow.
5. True, in PEA patient has an organised rythym but due to insufficient ventricular activity there is no detectable pulse.
6. True, transcutaneous pacing is used in patients ineffective to atropine therapy to pace their heart until permanent method of pacing is available . It delivers pulse of electrical current through the chest and stimulates heart to beat.
7. True, the time of treatment received by the patient determines the outcome from the affect of stroke , because the brain can't survive without blood ( maximum six minutes )and after this permanent damage occur, which requires emergency care to restore the functions. So the response depends upon the time the patient got the treatment .
8.True, breathing100% oxygen for extended periods of time will cause gas imbalance with carbon dioxide, removal of nitrogen from alveoli causing atlectasis and fibrosis and overwhelmes the bloods ability to carry oxygen away , affecting nervous system,retina etc.
9.True ,in a suspected stroke patient we must immediately obtain an IV access to provide the emergency medicine like TPA ,fluids etc to the patient.
10. False, ventricular fibrillation and PEA are different cardiac problem which should be dealt on different ways .VF needs urgent treatment as the patient does not have any pulse because there is no electrical activity in the heart,while PEA there is electrical activity but no detectable pulse.
11. False, if the AED advice no shock ,then no more shock has to given because AED senses the requirement for shock by the heart.
12. False , transcutaneous pacing must be used only after the failure of other interventions like atropine therapy etc.
13. False, cardioversion and defibrillator are used in pulseless tachycardia and antiarrthymic medicines are used in shock resistance tachycardia.
14. Minimize interruption between chest compression to no longer than 10 seconds for effective restoration of blood .
15.Oropharyngeal airway is not an advanced airway and is used to maintain a open airway by preventing the tongue from closing the epiglottis.
17. Atropine , because it is used in cases of bradycardia to increase the heart rate.
18. IV-IO-ET , the route which takes the drug into the systemic circulation fast is considered first.
19. Interosseous route is preferred after intravascular route because after IV it is the route which takes the drug into systemic circulation fastly .
