Q: Which specific heart block is characterized by a constant PR interval with
intermittent, non-conducted P-waves?
A: Second-degree atrioventricular (AV) block, Mobitz Type II. ✔✔
Q: For an intubated patient in cardiac arrest, what is the best objective
measurement to evaluate the effectiveness of chest compressions?
A: Closely monitor the patient’s end-tidal CO2 ($PetCO_{2}$) levels. ✔✔
Q: Where should EMS transport a patient who has successfully achieved ROSC
(return of spontaneous circulation) following a cardiac arrest?
A: To a specialized medical center capable of providing coronary reperfusion and
post-cardiac arrest care. ✔✔
Q: Which physical sign, when observed in an unresponsive individual, is a strong
indicator of cardiac arrest?
A: Cyanosis (a bluish discoloration of the skin caused by lack of oxygen). ✔✔
, Q: Which type of AV block is defined by a progressive lengthening of the PR
interval until a QRS complex is eventually dropped?
A: Second-degree atrioventricular (AV) block, Type I (Wenckebach). ✔✔
Q: If a patient has a pulse but requires assisted ventilation, what is the correct
frequency for delivering breaths with a bag-mask?
A: Squeeze the bag once every 5 to 6 seconds. ✔✔
Q: Beyond a physical clinical assessment, what is considered the gold standard for
confirming and monitoring the position of an endotracheal (ET) tube?
A: Continuous waveform capnography. ✔✔
You are caring for a patient with a suspected stroke whose symptoms started 2
hours ago. The CT scan was normal, with no signs of hemorrhage. The patient
does not have any contraindications to fibrinolytic therapy. Which treatment
approach is best for this patient? -ANSWER ✔✔Start fibrinolytic therapy as soon
as possible
Which best describes this rhythm? -ANSWER ✔✔Third-degree atrioventricular
block
What is the recommended range from which a temperature should be selected
and maintained constantly to achieve targeted management after cardiac arrest?
-ANSWER ✔✔32 degrees celsius to 36 degrees celsius
