NCAC II EXAM 2 2025 QUESTIONS WITH ANSWERS RATED
A+
✔✔*11. How does a drug enter the user's bloodstream when snorted or sniffed?*
a. by entering a blood vessel directly
b. through the membrane lining of the nasal passages
c. through the stomach wall
d. by passing through the small intestine - ✔✔*B: Through the membrane lining of the
nasal passages*
When a drug is snorted or sniffed, it collects directly upon the inner lining of the nose.
These nasal passages have sensitive membranes that then absorb the drug and pass it
into the user's system.
✔✔*12. Why do some users prefer the route of injection for drug administration?*
a. It provides a fast and high-peak effect.
b. It is easier to inject a drug than to take it other ways.
c. Needles are safer to use than other routes.
d. Injection has a lower chance of overdose. - ✔✔*A: It provides a fast and high-peak
effect*
Some users prefer injection for two main reasons. Injection not only provides a fast
means of getting the drug into the user's system, but it also allows for a higher peak
intensity.
✔✔*13. How does the route of inhalation pass the drug into the user's bloodstream?*
a. by the stomach lining
b. through a nasal membrane
c. directly via a blood vessel
d. through the lungs - ✔✔*D: Through the lungs*
When the user inhales a drug, it enters the bloodstream through the user's lungs. There
can be a rapid peak effect with this method of administration, but it is far more difficult to
use unnoticed.
✔✔*14. A user's expectation of how a drug will make the user feel...*
a. is of little significance.
b. can diminish a drug's intensity, but not enhance it.
c. has a significant effect upon the user's experience of the drug.
d. can enhance a drug's intensity, but not diminish it. - ✔✔*C: Has a significant effect
upon the user's experience of the drug*
Studies have shown that one's expectation of what a drug will do has a significant effect
upon how that drug is experienced by the user. For example, if the user expects the
drug to have a relaxing effect, the user is likely to feel relaxed after ingesting the drug.
,✔✔*15. What do short-term effects of drug use refer to?*
a. effects while the drug is still in the user's body
b. psychological effects prior to drug ingestion
c. physiological effects of drug use only
d. only psychological effects of drug use after the drug enters the user's system - ✔✔*A:
Effects while the drug is still in the user's body*
The short-term effects of drug use can be either physiological or psychological, and vary
significantly from individual to individual.
✔✔*16. A commonly seen physical effect of drug use is changes in...*
a. hair growth.
b. pupil size.
c. personal ideation.
d. delusions. - ✔✔*B: Pupil size*
There are several physical effects of drug use commonly seen in users. A few of the
most common, and most obvious to the alert observer, are changes in pupil size,
respiration, and heart rate. Delusions and personal ideation changes are psychological
in nature, and hair growth is not a common effect.
✔✔*17. What response to a drug has developed when increasing dosages of the drug
are required over time to achieve the same effect as the original dosage?*
a. tolerance
b. magnitude effect
c. causative tolerance
d. clinical ambivalence - ✔✔*A:Tolerance*
When a user takes a drug over a long period of time, a tolerance can develop to the
drug. This tolerance makes it necessary for the dosage of the drug to be increased in
order to achieve the same effects as the previous dosage.
✔✔*18. The reliability of a drug refers to...*
a. a drug producing the expected effects when ingested by the user.
b. the drug's ability to produce consistently the desired effects.
c. the drug being what the user intended to purchase.
d. the consistency of the cost per dosage. - ✔✔*C: It being what the user intended to
purchase*
There are many look-alike drugs and disreputable dealers in the drug trade. Therefore,
it can be difficult to be assured of the quality of drugs purchased on the street. The
reliability of a drug refers to the drug meeting the expectations of the buyer.
✔✔*19. Can drug use affect pregnant mothers?*
, a. no, because drugs are carried only through the user's bloodstream
b. yes, because the mother's blood circulates to the unborn baby
c. yes, but only when drugs are ingested orally
d. yes, but only when drugs are used with a nasal route of administration - ✔✔*B: Yes,
the mother's blood circulates to the unborn baby*
Drug use by pregnant women can affect the unborn baby, as the blood can be carried
through the mother's bloodstream to the baby. The unborn baby can also become
addicted to a substance, and once born (and the drug connection removed) suffer
withdrawal symptoms.
✔✔*20. Intellectual disability and growth retardation and physical deformities are
common symptoms of...*
a. Fetal Alcohol Syndrome.
b. heroin post-birth addiction.
c. all prenatal drug use.
d. overuse of prenatal pain killers. - ✔✔*A: Fetal Alcohol Syndrome*
Women who habitually use alcohol while pregnant can cause permanent damage to
their children, including mental, growth, and physical issues.
✔✔*21. Which of the following is the MOST commonly used sedative-hypnotic drug?*
a. anti-anxiety drugs
b. barbiturates
c. alcohol
d. muscle relaxants - ✔✔*C: Alcohol*
Alcohol, in all its forms, slows down the body's processes and is therefore known as a
depressant. It is commonly used in one of three forms: beer, wine, or distilled spirits.
One of the reasons for its widespread use is that it is legally obtainable.
✔✔*22. Barbiturate drugs are derived from...*
a. the cocoa bean.
b. barbituric acid.
c. turpentine.
d. anaphylactic acid. - ✔✔*B: Barbituric acid*
Barbiturate drugs are derived from barbituric acid, and there are thousands of different
types. They are a type of sedative-hypnotic drug and used more often by females than
by males—possibly because women are more likely to seek medical attention than men
are.
✔✔*23. Why can an overdose of a barbiturate cause death?*
a. It targets the impulse-control centers of the brain.
b. It causes a fast-acting negative effect on the kidneys.
