,Q1 INTEGRATE THE 2025 AHA GUIDELINES ON HIGH-QUALITY CPR INTO CLINICAL
DECISION-MAKING
During adult CPR, the coronary perfusion pressure (CPP) is a critical determinant
of return of spontaneous circulation (ROSC). If the aortic diastolic pressure is 40
mmHg and the right atrial diastolic pressure is 12 mmHg, what is the CPP, and
how does this value influence the likelihood of ROSC?
A. CPP is 28 mmHg; this is below the threshold of 30 mmHg, so ROSC is less likely.
CORRECT
B. CPP is 52 mmHg; this is above the threshold of 30 mmHg, so ROSC is more likely.
C. CPP is 28 mmHg; this is above the threshold of 25 mmHg, so ROSC is more likely.
D. CPP is 12 mmHg; this is below the threshold of 20 mmHg, so ROSC is less likely.
RATIONALE: CPP = aortic diastolic pressure - right atrial diastolic pressure. Here, 40 - 12 = 28
mmHg. A CPP of at least 30 mmHg is associated with higher ROSC rates; thus 28 mmHg is
below that threshold. Option B incorrectly adds the pressures, while D misidentifies the right atrial
pressure as the CPP. Option C uses an outdated threshold.
Q2 INTEGRATE THE 2025 AHA GUIDELINES ON HIGH-QUALITY CPR INTO CLINICAL
DECISION-MAKING
A patient in cardiac arrest has a return of spontaneous circulation (ROSC). Which
post-cardiac arrest intervention is most likely to improve neurologically intact
survival, and what is the underlying mechanism?
A. Immediate administration of antiarrhythmic drugs to prevent recurrent arrest.
B. Targeted temperature management (TTM) to 32-36°C for at least 24 hours to reduce
reperfusion injury. CORRECT
C. Rapid infusion of cold intravenous fluids to achieve hypothermia.
D. Immediate coronary angiography for all patients regardless of ECG findings.
RATIONALE: TTM (32-36°C) is recommended for comatose patients after ROSC to mitigate
hypoxic-ischemic brain injury. Antiarrhythmics are not routinely indicated post-ROSC. Cold IV
fluids are not recommended for TTM. Coronary angiography is indicated for those with
ST-elevation or suspected coronary cause, not all patients.

DECISION-MAKING
In a two-rescuer adult CPR scenario, a bag-mask device is being used. Which of
the following techniques best ensures adequate ventilation while minimizing the
risk of gastric insufflation?
A. Deliver each breath over 2 seconds with a sufficient volume to produce visible chest rise,
using a two-hand jaw-thrust.
B. Deliver each breath over 1 second with a volume of 600 mL, using a one-hand head-tilt
chin-lift.
C. Deliver each breath over 1 second with a volume sufficient to produce visible chest rise, using
a two-hand jaw-thrust. CORRECT
D. Deliver each breath over 2 seconds with a volume of 1000 mL, using a one-hand head-tilt
chin-lift.
RATIONALE: Current guidelines recommend delivering each breath over 1 second, with just
enough volume to produce visible chest rise (approximately 500-600 mL), using a two-hand
jaw-thrust to maintain an open airway and prevent gastric insufflation. Options A and D use
2-second durations, which are outdated and increase the risk of hyperventilation. Option B uses
a one-hand technique, which is less effective in maintaining a seal.
Q4 INTEGRATE THE 2025 AHA GUIDELINES ON HIGH-QUALITY CPR INTO CLINICAL
DECISION-MAKING
During CPR, the compression-to-ventilation ratio for a single rescuer of an adult is
30:2. However, once an advanced airway is placed, ventilations are delivered at a
rate of 1 breath every 6 seconds without pausing compressions. What is the
physiological rationale for this change in ventilation strategy?
A. Continuous compressions with asynchronous ventilations maintain higher coronary perfusion
pressure. CORRECT
B. The advanced airway prevents gastric insufflation, allowing higher tidal volumes.
C. This rate matches the patient's spontaneous respiratory rate, reducing hyperventilation.
D. It allows the rescuer to avoid fatigue by reducing the total number of breaths per minute.
RATIONALE: With an advanced airway, compressions are continuous, eliminating pauses that
produce a drop in coronary perfusion pressure. Ventilations are given at 1 breath every 6
seconds (10/min) to avoid hyperventilation, but the primary benefit is uninterrupted
compressions. Option B is not the main rationale. Option C is incorrect because the patient is
apneic. Option D is not the primary physiological basis.

, Q5 INTEGRATE THE 2025 AHA GUIDELINES ON HIGH-QUALITY CPR INTO CLINICAL
DECISION-MAKING
A team is performing CPR on an adult in cardiac arrest. The compressor is
providing high-quality compressions, but the team leader notices that the chest
recoil is incomplete. Which of the following is the most likely consequence of
incomplete chest recoil, and how should it be corrected?
A. Decreased cardiac output due to reduced venous return; the compressor should lean less on
the chest between compressions. CORRECT
B. Increased risk of rib fractures; the compressor should reduce compression depth.
C. Increased coronary perfusion pressure; no correction is needed.
D. Decreased ventilation efficiency; the compressor should increase compression rate.
RATIONALE: Incomplete chest recoil prevents the chest from fully expanding, which reduces the
negative intrathoracic pressure that drives venous return, leading to decreased cardiac output.
The correct action is to allow full recoil by leaning less. Reducing depth or increasing rate would
worsen outcomes. Increased CPP is not a consequence.
Q6 INTEGRATE THE 2025 AHA GUIDELINES ON HIGH-QUALITY CPR INTO CLINICAL
DECISION-MAKING
A patient with a suspected opioid overdose is unresponsive and not breathing
normally but has a pulse. Which action is the priority, and what is the sequence of
interventions?
A. Begin CPR with compressions and ventilations at a ratio of 30:2, then administer naloxone.
B. Administer naloxone immediately, then provide rescue breathing.
C. Provide rescue breathing (1 breath every 5-6 seconds) and administer naloxone, monitoring
for response. CORRECT
D. Apply an AED and analyze the rhythm, then deliver a shock if indicated.
RATIONALE: For a patient with a pulse and abnormal breathing, rescue breathing is indicated (1
breath every 5-6 seconds, about 10-12 breaths/min). Naloxone should be administered as soon
as available. CPR is not indicated because a pulse is present. AED is for cardiac arrest
(pulseless). The priority is ventilation, as opioid overdose causes respiratory depression.
