The best answer is D, 1 and 3 only.

Here's Why: Lidocaine is administered at 1.0 - 1.5 mg/kg IV boluses. These can be repeated at one half the initial dose up to a total of 3.0 mg/kg. If lidocaine is effective, a continuous infusion can be initiated at 40 mcg/kg/minute. (50 kg pt. = 2 mg/min; 75 kg pt. = 3 mg/min; and 100 kg pt. = 4 mg/min)

The best answer is C, Morphine sulfate.

Here's Why: Many practitioners mistakenly reach for benzodiazepam agents such as diazepam or midazolam. Neither of these drugs provide analgesia for the patient. The TCP produces significant pain in many patients, thus, the use of carefully titrated IV narcotic analgesia is recommended. In unstable patients, oral drugs should not be given.

The best answer is A, True.

Here's Why: Best treatment of ventricular fibrillation or unstable or pulseless ventricular tachycardia is electrical counter-shock. Although some patients with ventricular tachycardia will convert when a fist crashes down on their chest at high velocity, the poor number of conversions coupled with the potential for chest trauma makes shocking the patient more sensible.
