B. Schedule II: Schedule II drugs have accepted medical uses but also have a high potential for abuse and dependence (e.g., oxycodone, morphine).
C. Schedule III: Schedule III drugs have accepted medical uses and a lower potential for abuse compared to Schedule II (e.g., ketamine, anabolic steroids).
D. Schedule IV: Schedule IV drugs have accepted medical uses and an even lower potential for abuse (e.g., diazepam, lorazepam).

Correct Answer is B
Explanation
A. Aim the discharge at the top of the fire: The correct action is to aim at the base of the fire, not the top.
B. Move the extinguisher from side to side: This is the correct technique for using a fire extinguisher (PASS method: Pull, Aim, Squeeze, Sweep). Sweeping the extinguisher from side to side helps cover the area of the fire.
C. Shake the extinguisher before using: Shaking is not necessary and might not be recommended; instead, you should ensure the extinguisher is in working order.
D. Squeeze the handle before pulling the pin: The pin should be pulled first to unlock the extinguisher before squeezing the handle.
Correct Answer is D
Explanation
A. Take the patient's pulse for 5 seconds and multiply by 10: Measuring for 5 seconds and multiplying by 10 is less accurate due to the short measurement time.
B. Take the patient's pulse for 15 seconds and multiply by 2: While this method is more accurate than taking it for 5 seconds, the recommended practice is to measure for 30 seconds for better accuracy.
C. Take the patient's pulse for 30 seconds and multiply by 4: This would be used to determine a pulse rate per minute from a 15-second measurement, not 30 seconds.
D. Take the patient's pulse for 30 seconds and multiply by 2: This method provides a precise measurement of the pulse rate, as taking the pulse for 30 seconds and then multiplying by 2 gives the number of beats per minute.
