Name two drugs and example what they can do to your body if you misuse them?

Answers

Answer with Explanation:

1. Painkillers/Pain relievers = Painkillers are commonly over-the-counter medications which people take for headaches or fever. It can also be prescribed by doctors and it actually works with wonders if taken accordingly. However, if a person relies on it too often, this will lead to a higher tolerance for the drug. Thus, the person will need to increase his dosage every time in order to relieve himself from pain. A high dosage of pain reliever may lead to death.

2. Sedatives like "sleeping pills." = Sleeping pills are commonly given to people who have a hard time sleeping. Sometimes it makes people too dependent on them that they take it every day. This should only be used in a short-term period. This could lead to an abuse of using them and thereby increasing one's tolerance. This means that, the person will have to increase his dosage without the prescription of the doctor. In some cases, they seek medical help from other doctors to get an additional refill. If they ever decided to undergo rehabilitation, it will be hard for them to recover and they may experience the so-called "rebound insomnia."

Bloodborne diseases cannot be transmitted by any other means than
needlesticks.
TRUE
FALSE

Answers

Answer:

false

Explanation:

can also be transmitted through semen, cerebrospinal fluid, vaginal secretions

Answer:

False

Explanation:

bloodborne diseases can be transmitted through cross contamination of reused needles, but it can also be transmitted through a simple mixing of blood. Say person A and person B both have injured hands, and person A has a bloodborne disease, and they shake hands. if person A's blood gets into person B's blood, chances are person B will get the bloodborne disease as well, or they will be exposed to it none the less. it can be spread through contaminated blood donations (however, people are heavily tested and cleared before being allowed to donate blood). Any form of transmission of contaminated blood to non contaminated blood, can and will transmit bloodborne diseases.

I'm also semi sure that they can be spread through mixing other bodily fluids as well.
