1If the CPR (cardiopulmonary resuscitation) is provided with rescue breaths what is the correct ratio between chest compression and rescue breaths?
- A3 rescue breaths per minute
- B2 rescue breaths every 30 chest compressions
- C60 to 80 rescue breaths per minute
2CPR (cardiopulmonary resuscitation) may be terminated
- AIf the victim stays unconscious for 30 minutes or longer
- BIn case that the victim starts to breathe or awakes
- CIn case of the doctor's instruction
3What is the correct ratio of CPR (chest compression)?
- A10 to 12 chest compressions per minute
- B100 chest compressions per minute
- C130 chest compressions per minute
4CPR (cardiopulmonary resuscitation) may be terminated
- AIn case of total exhaustion of the rescuer
- BAfter recovery of cardiac activity (victim starts to breathe normally)
- CIf the cardiac activity is not restored within 5 minutes
5Select the correct procedure for first aid procedure in case of electric shock:
Steps:
1. Extricate the victim out of the electrical circuit (turn off power supply)
2. notify the supervisor as soon as possible and prepare a record of the accident
3. If necessary, commence CPR (the rescue breaths are optional)
4. check response, clean airways, determine whether the victim is breathing
5. call a medical help ( do not leaving the victim alone)
6. treat any secondary injures- A1, 2, 4, 3, 6, 5
- B1, 4, 5, 3, 6, 2
- C1, 5, 6, 4 ,3, 2
6Before starting CPR, during check the breathing, the following is necessary
- ACheck & clean the airways
- BLay the victim on a soft pad
- CLean the victim's head back
7Before commencement of CPR it is necessary:
- Ato lay the victim on his/her back on the soft and flat pad
- Bto provide the victim a drink (water)
- Cto lay the victim on his/her back on the rigid and flat surface
8The rescuer position during the CPR shall be as follow:
- Aupper limbs are stretched in the elbows
- Bupper limbs are bent at the elbows
- Cone hand is inserted under the back of the victim and the other hand is used to provide CPR
9When performing chest compressions (CPR), the chest compression shall be made as follow
- Ato a depth of 4-5 cm
- Bup to a depth of 2 cm, to avoid damage of victim's sternum
- Ca rate of about 100 compressions per minute
10if the victim remains conscious/awakes from unconsciousness after an electric shock, he/ she is not visibly injured, breathes normally
- Ait is highly recommended to call a doctor or bring him to the medical check
- Bmay continue to work, but no later than 24 hours, he should see a doctor
- Cthe supervision shall be performed (the victim shall not be left alone)
11When an accident in the electrical system above 1000 V occurs (especially in the fall of MV/HV wires), it is necessary to carry out rescue work prudently, because
- Abefore carrying out rescue operations, it is necessary to issue the command "B" (acc to Czech standards)
- Bthe injury must first be announced to the workers of the nearest substation
- Cthere is a risk of the step/touch voltage occurrence
12It is possible to extricate the victim out the electrical circuit (out of reach of current) by the following way
- Apulling out the affected person using insulated rescue hook or similar tool
- Bturning off the power supply
- Csliding/pushing the source of injury (eg bare conductors out of the victim's body) using insulated rescue hook or similar tool
13Emergency medical service in Czech Republic can be contacted using the emergency telephone number
- A150
- B155 or 112
- C158
14In the event of fire in laboratories FEECS, students/crew shall immediately announce the fire at the telephone number ...
- Amobile No. 596 991 111, internal telephone No. 1111
- Bmobile No. 596 992 121, internal telephone No. 2121
- Cmobile No. 596 993 111, internal telephone No. 3111
15The extinguishing the electrical equipment which is, or may be live, due to risk of injury caused by electric shock, is impossible to perform using:
- AWater-type fire extinguisher
- BFoam-type fire extinguisher
- CPowder-type fire extinguisher
16Mark the possible risk to people in case of fire occurrence in the indoor areas:
- ASuffocation by toxic smoke
- BLoss of orientation and subsequent unavailability to find escape path caused by low visibility
- CBurn of people
- DPanic with subsequent risk of impossible proper evacuation
17University students working in laboratories of faculty of electrical engineering and computer science are considered as instructed persons ($4 acc. To Decree 50/1978 Coll ( provided that they:
- Aare trained from First aid procedure and acquainted with risks that electricity may create, usually provided in lectures held in "Safety at electrical engineering" subject.
- Bare trained from local safety rules for each particular laboratory where they perform work activities, emphasizing particular risks and operation rules
- Csimply commence the study at university (no further condition is needed)
18University students working in Laboratories of Faculty of Electrical Engineering and Computer Science are considered as instructed persons ($4 acc. To Decree 50/1978 Coll.) they are allowed to perform these activities:
- Awork in the vicinity of live parts (20 cm) with inspection of supervisor
- Bperform live working without any restrictions
- Cin general, they are not allowed to perform live working except for measurement and approved simple work procedures
19The limit of ELV (extra-low voltage is in normal areas - i.e dry non-conductive areas) for insulated conductors and/or equipment protected against unintentional touch by e.g enclosures
- A50 V AC and/or 120 V DC
- B25 V AC and/or 60 V DC
- C12 V AC and/or 25 V DC
20Mark the work activities which are banned to students in school laboratories
- APerform live working (except of measurement and approved simple work procedures)
