Chain of Survival Flashcard 4
Rationale
C. Rationale: Studies show that there is a high incidence of in-hospital cardiac arrest due to respiratory failure and circulatory shock. Clinicians must be aware and intervene immediately once patients show signs and symptoms of impending respiratory failure or circulatory shock to increase the survival rates of these critically ill patients.
Question
Which of the following is a common cause of in-hospital cardiac arrest?
a. Infectious disease
b. Malignancy
c. Respiratory failure
d. Renal failure
Answer
c. Respiratory failure
Rationale

Rationale
A. Rationale: The magnifying glass symbolizes the availability of effective surveillance systems for patients to prevent in-hospital cardiac arrest. The magnifying glass is the first link in the in-hospital adult chain of survival.
Question
Which of the following symbols of the in-hospital adult chain of survival pertains to the availability of an effective surveillance system to prevent in-hospital cardiac arrest?
a. Magnifying glass
b. Telephone
c. Hands
d. Heart
Answer
a. Magnifying glass
Rationale
D. Rationale: Stakeholders of out-of-hospital cardiac arrest systems of care can use continuous quality improvement tools such as LEAN, Six Sigma, and Plan-Do-Check-Act.

a. LEAN
b. Plan-Do-Check-Act
c. Six Sigma
d. All of the above
Answer
d. All of the above
Rationale
B. Rationale: Dispatchers of a public safety answering point such as 9-1-1 can instruct untrained lay rescuers in providing compression-only CPR to patients with out-of-hospital cardiac arrest.

Rationale: For out-of-hospital cardiac arrest, the following are important stakeholders: lay rescuers, emergency medical services personnel, emergency department personnel, cath lab staff, and ICU staff. The cath lab and ICU staff are involved in both in-hospital and out-of-hospital cardiac arrest.
Question
Which one of the following is involved in the treatment of patients with out-of-hospital cardiac arrest?
a. Primary providers
