Explanation:

Step1: Analyze question 146

Controlled substances are categorized by schedules. This is a standard classification in the field of medicine and health.

Step2: Analyze question 147

"i po bid" means one tablet by mouth twice a day. Each tablet is 150mg. So the daily dose is \(150\times2 = 300\)mg.

Step3: Analyze question 148

The abbreviation for grain is "gr". This is a common abbreviation in medical terminology.

Step4: Analyze question 149

For Demerol: The concentration is 100mg/mL and the required dose is 80mg. Using the formula \(V=\frac{D}{C}\) (where \(V\) is volume, \(D\) is dose, \(C\) is concentration), \(V_{Demerol}=\frac{80}{100}=0.8\)mL. For Vistaril: The concentration is 50mg/mL and the required dose is 50mg. \(V_{Vistaril}=\frac{50}{50} = 1\)mL. The total volume \(V = 0.8+1=1.8\)mL.

Step5: Analyze question 150

In Roman numerals, "D" represents 500.

Answer:

1. A. schedules
2. C. 300mg
3. B. gr
4. A. 1.8mL
5. D. 500
