CH 15 Shock and Resuscitation EMT
Study Post Exam Questions with Latest
Update
You have a patient in cardiac arrest with an unknown down time. What should be one of
the initial interventions by the EMS crew?
A.
Initiation of PPV with a BVM
B.
Placement of an advanced airway
C.
Administration of medications by an ALS provider
D.
2 minutes of CPR while the AED is being readied - Answer-2 minutes of CPR while the
AED is being readied
Rationale
If a patient goes into cardiac arrest in front of you, you should apply the AED and allow
it to assess the patient to determine whether a shock is indicated. However, if the
patient has been down for several minutes (or has been down for an unknown period of
time) before your arrival, 2 minutes of CPR would be indicated before use of the AED so
that the heart can be better perfused before application of the AED. Placement of an
advanced airway or administration of medications by an ALS provider should be done
only after high-quality CPR has been initiated and the AED has been applied and used
as appropriate.
Bringing a patient back from potential or apparent death is called:
A.
resuscitation.
B.
defibrillation.
C.
sudden death.
D.
cardiac arrest. - Answer-Resuscitation
Rationale
The term "resuscitation" means bringing the patient back from potential or apparent
death. The potential or apparent death may result from many different causes, including
trauma and medical conditions. Resuscitation focuses on management of the airway,
ventilation, and oxygenation, and restoring adequate circulation. Defibrillation is a care
, technique that may be used during resuscitation, and cardiac arrest and sudden death
are both etiologies that would require resuscitation.
What is the underlying cause for all the clinical findings that are seen in irreversible
shock?
A.
Overall system failure
B.
Hyperglycemia and hyponatremia
C.
Electrolyte imbalance
D.
Conversion from anaerobic metabolism to aerobic metabolism - Answer-Overall system
failure
In what stage of hemorrhagic might the EMT notice only subtle vital sign changes of
tachycardia and narrowing pulse pressure.
A.
Compensated
B.
Late
C.
Decompensated
D.
Irreversible - Answer-Compensated
Rationale
Compensated shock is the stage that has the fewest changes to the vital signs. This is
because the body is able to compensate for the lost volume. If the etiology of shock is
reversed in this stage, such as by stopping the hemorrhage, the compensatory
mechanisms will continue to maintain the blood pressure and perfusion and will
eventually begin to signal the body to decrease its response as the pressure is restored.
The blood pressure may appear to be relatively normal in compensated shock.
However, you might also note a narrow pulse pressure. In decompensated and
irreversible shock (sometimes called late shock), the body is unable to maintain
normalcy due to the volume loss, and there is often a decreasing slope to the systolic
blood pressure.
You are applying the AED pads to an elderly patient in cardiac arrest. The patient also
has an implanted pacemaker. You should:
A.
not use the AED on this patient.
B.
