CPR - Certified Paramedic Response Special Resuscitation Circumstances Questions and Answers

Question 1

A 34-year-old female who is approximately 30 weeks pregnant collapses in cardiac arrest. While performing high-quality CPR, what is the most critical manual intervention to improve the effectiveness of resuscitation?

Accepted Answer

Manually displacing the uterus to the patient's left side.

Answer

In a visibly pregnant patient (generally after 20 weeks gestation), the gravid uterus can compress the inferior vena cava and aorta, a condition known as aortocaval compression. This severely impedes venous return to the heart and reduces the effectiveness of chest compressions. Manually displacing the uterus to the patient's left is the primary intervention to relieve this pressure and is a critical component of maternal resuscitation.

Question 2

During the resuscitation of a severely hypothermic patient in cardiac arrest with a core temperature of 28°C (82.4°F), which of the following is the most appropriate approach to defibrillation and ACLS medication administration?

Accepted Answer

A single defibrillation attempt may be made, and subsequent shocks and IV medications should be withheld until the core temperature is above 30°C (86°F).

Answer

In severe hypothermia (core temperature <30°C or 86°F), the myocardium is less responsive to defibrillation and medications, and drug metabolism is slowed. Current guidelines suggest that it is reasonable to perform an initial defibrillation attempt for a shockable rhythm but to withhold further shocks and ACLS medications until the core temperature has been raised to at least 30°C (86°F). Once above this temperature, medications may be given at longer intervals.

Question 3

You have just pulled an unresponsive, apneic, and pulseless adult from a swimming pool. After ensuring scene safety and activating EMS, what is the most appropriate first step in the resuscitation sequence for this drowning victim?

Accepted Answer

Open the airway and deliver 2 to 5 initial rescue breaths before starting chest compressions.

Answer

Cardiac arrest in drowning is primarily caused by hypoxia (lack of oxygen). Therefore, restoring oxygenation is the immediate priority. Updated guidelines emphasize opening the airway and providing initial rescue breaths before initiating chest compressions. This differs from standard CPR for a presumed primary cardiac event where the emphasis is on immediate chest compressions.

Question 4

Which of the following is a primary, potentially reversible cause of traumatic cardiac arrest that a paramedic should immediately address with a specific procedural intervention in the field?

Accepted Answer

Tension pneumothorax

Answer

In traumatic cardiac arrest (TCA), the focus is on treating reversible causes, often remembered by mnemonics like HOTT (Hypovolemia, Oxygenation, Tension pneumothorax, Tamponade). A tension pneumothorax is a life-threatening condition that can be rapidly treated in the prehospital setting by performing a needle decompression (thoracostomy), potentially restoring circulation. The other conditions listed are not directly reversible with a specific paramedic procedure in the field.

Question 5

A 28-year-old is found in cardiac arrest with suspected opioid overdose. Bystanders are performing chest compressions. According to AHA guidelines, what is the correct priority of interventions for this patient?

Accepted Answer

Prioritize high-quality CPR with ventilations and use an AED; administer naloxone without interrupting these core resuscitation efforts.

Answer

For a patient in cardiac arrest from a suspected opioid overdose, the cornerstone of treatment is high-quality CPR and ventilation to manage the severe hypoxia. While naloxone administration is recommended for suspected opioid overdose, it should not delay or interrupt fundamental BLS and ALS interventions like CPR and defibrillation. The priority is to address the arrest with standard, proven therapies while considering naloxone as a concurrent but secondary action.
