Final answer:
The information provided concerns the application of voltage using a defibrillator during cardiac events and the principles of Ohm's Law, rather than the dosing of Lidocaine.
Step-by-step explanation:
The student's question is about the appropriate dosing of Lidocaine for adult cardiac arrest in a clinical setting. However, the additional references provided do not speak directly to Lidocaine dosing but rather to the use of a defibrillator during cardiac events such as surgery or cardiac arrest, as well as safety considerations when using electric currents in a medical context. Specifically, calculating the voltage to apply based on resistance and current needs using Ohm's Law (V = IR) and understanding the impact of current on the human body are covered. For the mentioned defibrillator case, with a path resistance of 500 ohms and a needed current of 10.0 mA, the voltage required can be determined to be 5 volts (V = IR, so V = 0.01 A × 500 Ω = 5 V).
