ACLS Prep Post-Test 2024

Which two “D’s” of the eight “D”s of stroke care, both address the importance regarding recommendation for the EMS providers to now provide prehospital notification regarding the arrival of potential stroke victim?

 The high quality CPR has been halted on a patient due to a jump in the ETCO2 from 13 (indicator of great chest compressions as > 10) to now 35 on the monitor.

A pulse is palpated and blood pressure has now been stabilized with a systolic B/P > 90. The patient is unable to follow simple commands, making him a candidate for consideration of what therapy?

The below block is has a very regular R-R interval, and more frequently a very slow rate of 20-40.  Notice all of the P-waves (black dots) will march out, and all of the QRS complexes ( white dots ) will march out. But they are not “communicating” at all, the ventricles are getting no impulse from the atria above, so the ventricles have initiated an impulse and are producing the pulse and blood pressure without atrial involvement. This is a dangerous block, as generally the rate is low and slow

This patient is in a monomorphic Ventricular Tachycardia (VT)  with a palpable, but faint pulse. His blood pressure is 74/40 and the patient is pale and monosyllabic. Which is the most appropriate, immediate treatment?

Which of the following is included in the attempt to increase Chest Compression Fraction (CCF) in a victim who has not yet achieved return of spontaneous circulation (ROSC).

2 minutes of CPR has just been completed and the below rhythm is on the monitor screen. A  pulse check is performed, and no pulse is found. Which describes the next best step (s) which should be performed?

The patient is complaining of dizziness and shortness of breath with a blood pressure of 68/48. Which best describes the patients presentation and recommended urgent treatment?

Hyperventilation can cause a decrease in cardiac output which can then result in an anoxic event to the victim.

Notice how all of the dots (P- waves and are indicated with both the black and white dots above the P-waves for a total of 6 dots on this strip) march out at a regular rate.

The black dot P-waves have normal QRS-T waves which follow them. These beats are normal, regular and will all look alike. Now notice the white dot P-waves (difficult to see the white dots- there are 3 of them- above these “stand alone” P-waves),they have no QRS-T which follows them. This is a called a “dropped beat”, meaning no impulse goes through the junction and creates a ventricular contraction and repolarization also known as the QRS-T.

The R-R interval is very irregular in this block due to the white P-wave dropping beats at no predictable pattern or time. What type of block of dangerous, unpredictable block is this example?

Treatment of this rhythm includes early defibrillation, high quality CPR, Epinephrine and a choice between Amiodarone or Lidocaine for the anti-arrhythmic therapy. Which one of the two lethal, shockable rhythms is this?
