Answer to Question 1

Answer: 2
Explanation: The drug's ability to bind to a particular receptor site is referred to as its selectivity. Affinity refers to how strong an interest or attraction a drug might have for a particular receptor. The drug's ability to produce a response once it has been bound or attached itself to the receptor is called its intrinsic activity. Hyperosmolarity refers to particularly high concentrations of a substance.

Answer to Question 2

Answer: 2
Explanation: Psychiatric medications work by targeting specific neuronal cells and synapses in the central nervous system. Although some psychotropic medications may affect neurotransmitters in the stomach, this is not a target effect. To say that the medication will target the entire central nervous system is incorrect. To say that the medication will enter the bloodstream and find the targeted area is vague and misleading.
