The correct method for delivering a proper rescue breath involves pinching the nose, sealing the lips, and breathing into the mouth until you see the chest rise. This technique is critical because it ensures that the air you deliver is directed into the lungs, facilitating effective ventilation. By pinching the nose, you prevent air from escaping through the nasal passages, while sealing the lips around the patient's mouth ensures a tight fit so that air does not leak out.

The goal is to clearly observe the rise of the chest, which indicates that the breaths are being delivered effectively and that air is entering the lungs. This visual confirmation is essential to assure that the breaths are not only being administered but are also having the intended effect of providing oxygen to the patient.

The other methods mentioned do not effectively ensure that the air reaches the lungs or are less efficient in providing adequate ventilation. Proper technique is vital in emergency situations to maximize the chances of successful resuscitation and recovery.
