Drugs that have an accepted use in the surgical setting are on the ____________ schedule.
rusak2 [61]

Drugs that have an accepted use in the surgical setting are on the <u>C-II </u>schedule.

Five drug schedules were created and categorised under the Controlled Substance Act in order to regulate their manufacturing and distribution. A requirement of the law states that pharmacists who fill prescriptions for scheduled substances must have a licence from the Drug Enforcement Administration.

The licences of health professionals include special licence numbers that make it possible to trace and associate restricted drug prescriptions with a particular practitioner or distributor.

Drugs in Schedule II are less likely than those in Schedule I to cause use disorders. They are more susceptible to developing physical and mental dependency. They are very susceptible to overuse as well as use disorders. They are frequently used to treat ADHD, sleeplessness, anxiety, and severe pain.

Hydromorphone (Dilaudid®), methadone (Dolophine®), meperidine (Demerol®), oxycodone (OxyContin®, Percocet®), and fentanyl (Sublimaze®, Duragesic®) are a few examples of Schedule II narcotics. Morphine, opium, codeine, and hydrocodone are further Schedule II drugs.

IF A CUBE IS 1CM ON A SIDE, CALCULATE ITS SURFACE AREA. HINT WRITE 2 points
frosja888 [35]

Answer:

Surface area of the cube = 6cm²

Volume of the cube = 1cm³

Explanation:

The surface area of a cube, which refers to the sum of all the areas of the faces of the cube can be calculated using the formula:

S.A = 6 × a²

That is; a² + a² + a² + a² + a² + a²

Where;

a = length of a side of a cube

a² = area of one side of a cube

Note that, a cube has 6 faces

According to this question, a cube has a length of 1cm on each side.

Hence, S.A = 6 × 1²

S.A = 6 × 1

S.A = 6cm²

Volume of the cube can be calculated using the formula: a³

Where a = 1

Volume = 1 × 1 × 1

Volume = 1cm³
