Correct Answer is A

Explanation

Correct answer: a) Opioids

Rationale: Opioids are controlled substances that act on opioid receptors to produce analgesia, euphoria, sedation, and respiratory depression. Nausea and vomiting are common adverse effects of opioids due to stimulation of the chemoreceptor trigger zone in the brain.

Incorrect choices:
b) Stimulants: Stimulants are controlled substances that increase alertness, energy, mood, and heart rate. Nausea and vomiting are not typical adverse effects of stimulants.
c) Depressants: Depressants are controlled substances that reduce anxiety, agitation, and insomnia. Nausea and vomiting are not typical adverse effects of depressants.
d) Hallucinogens: Hallucinogens are controlled substances that alter perception, cognition, mood, and behavior. Nausea and vomiting are not typical adverse effects of hallucinogens.

A. Controlled substances B. Legend drug C. Over-the-counter drug D. Herbal supplement

Correct Answer is B

Explanation

Correct answer: b) Legend drug

Rationale: Lithium carbonate is a legend drug, which means that it requires a prescription from a licensed provider and has a label that states "Caution: Federal law prohibits dispensing without prescription." Legend drugs are not classified as controlled substances unless they have a potential for abuse or dependence.

Incorrect choices:
a) Controlled substances: Controlled substances are drugs that have a potential for abuse or dependence and are regulated by the Drug Enforcement Administration (DEA). They are classified into five schedules based on their medical use and abuse potential.
c) Over-the-counter drug: Over-the-counter drugs are drugs that do not require a prescription and can be purchased by consumers without supervision from a health care provider. They have labels that state "Drug Facts" and provide information about their ingredients, uses, warnings, directions, and other information.
d) Herbal supplement: Herbal supplements are products that contain plant extracts or other natural ingredients that are intended to supplement the diet or promote health. They are not regulated by the Food and Drug Administration (FDA) as drugs but as dietary supplements. They have labels that state "Supplement Facts" and provide information about their ingredients, serving size, amount per serving, and other information
