Final answer:
Without specific information about the content of Lesson 3 in a CPR course, it is challenging to determine which supplies are not needed. Typically, a bag-valve-mask, latex-free gloves, CPR breathing barriers, and AED Training Pads are used in comprehensive CPR training.
Step-by-step explanation:
To determine which materials, equipment, and supplies are not required for Lesson 3 on CPR breathing, we must consider the typical components of a CPR course. Generally, a bag-valve-mask (BVM) is used to provide ventilation to a patient in a controlled manner. Latex-free nitrile gloves are essential to protect the rescuer and the victim from potential cross-contamination. CPR breathing barriers, such as face shields or masks, are crucial in preventing direct contact with the patient's bodily fluids during resuscitation. Lastly, AED Training Pads are used to simulate the use of an Automated External Defibrillator during CPR training. Without specific information on the content of Lesson 3, it is difficult to accurately identify which items are not required. If Lesson 3 deals solely with the techniques of hands-only CPR, for instance, then a BVM and CPR breathing barriers might not be necessary. However, if Lesson 3 encompasses the full scope of CPR training, including both chest compressions and ventilation, all these items could be necessary.
