Medications classified due to their potential for misuse or addiction are known as:
OTC
Therapeutic
Adjuvant
Controlled
The Correct Answer is D
A. OTC: Over-the-counter medications are available without a prescription and are generally considered safe when used as directed. They are not regulated for potential misuse or addiction.
B. Therapeutic: Therapeutic medications are classified by their intended use or pharmacologic effect, not by their potential for abuse. The classification focuses on treatment purpose rather than regulatory control.
C. Adjuvant: Adjuvant medications are used to enhance the effect of primary therapy, such as pain adjuvants in neuropathic pain. They are not inherently controlled or associated with misuse potential.
D. Controlled: Controlled substances are regulated by federal law due to their potential for misuse and addiction. These medications require specific prescribing, dispensing, and documentation practices to ensure safe use and prevent diversion.

Correct Answer is C
Explanation
A. Severe: The term “severe” describes the intensity or seriousness of an adverse reaction, not a reaction opposite to the intended therapeutic effect. It refers to magnitude rather than the direction of the response.
B. Allergic: An allergic reaction is an immune-mediated response to a medication, such as rash, anaphylaxis, or urticaria. It does not describe a response that produces effects opposite to the drug’s intended action.
C. Paradoxical: A paradoxical reaction occurs when a medication produces an effect opposite to that expected, such as a sedative causing agitation or insomnia. This response may be due to individual variation in metabolism, receptor sensitivity, or central nervous system effects.
D. Toxic: Toxicity refers to harmful effects caused by excessive drug levels or accumulation, leading to organ damage or systemic harm. Toxic effects may be exaggerated but are not inherently opposite to the intended therapeutic outcome.
Correct Answer is C
Explanation
A. Hypertonic: Hypertonic solutions have a higher solute concentration than human blood, causing water to move out of cells and leading to cellular shrinkage. These solutions are used in specific clinical situations such as reducing cerebral edema. They do not match normal plasma osmolality.
B. Hyperosmolar: Hyperosmolar refers to a solution with increased total osmoles per liter, which may or may not be equal to blood concentration. This term describes osmotic strength rather than equivalence to plasma. It does not specifically indicate the same solute concentration as blood.
C. Isotonic: Isotonic solutions have the same solute concentration and osmotic pressure as human blood plasma. They do not cause net fluid movement into or out of cells, maintaining normal cell size and function. Common examples include 0.9% normal saline and lactated Ringer’s.
D. Hypotonic: Hypotonic solutions have a lower solute concentration than blood, causing water to move into cells and potentially leading to cellular swelling. These fluids are used cautiously due to the risk of edema. They do not match plasma solute concentration.
