(C). At least 100/min
(D). As many as you can

The basics of CPR has changed since 2010. Major changes for all rescuers, all of which are intended to simplify CPR for rescuers and improve bystander response, include:

• A change in the CPR sequence, from Airway-Breathing-Compressions (A-B-C) to Compressions-Airway-Breathing (C-A-B)
• Continued emphasis on providing high-quality chest compressions:Push hard, push fast. Minimize interruptions. Allow full chest recoil. Avoid excessive ventilation.
• Chest should be depressed at least 2 inches (as opposed to approximately 1 ½ to 2 inches, recommended in 2005)
• Chest compressions should be performed at a rate of at least100/min (the 2005 recommendation was to “compress at a rate of about 100/min”)

Answer: (C). At least100/min

When solving this problem, did you choose “(B). 100/min?” The difference between “(B). 100/min” and “(C). At least 100/min” is minor. However, for an exam, this one question can determine your PASS or FAIL, so we need to pay attention. As we have reviewed, the correct answer is “at least” 100/min. This question illustrates how important it is to pay attention to every single word you see not only in the question but also in the answer choices. It takes a lot of effort to go through the dental hygiene board exams (NBDHE, NDHCE) that takes 4+ hours. Staying focused for the entire length of the exam and paying attention to every detail is extremely difficult. It is like running a marathon. So the best thing you can do is to practice the mock exam. StudentRDH has timed mock exams for both the Canadian and US national dental hygiene boards. If you join the course, you will be able to prepare yourself for this big day so much better. All students who have taken the mock boards with StudentRDH felt so much more confident. But enough about StudentRDH – the point today was to know the basics of CPR. Have another fabulous day!
