Key Concepts in Psychopharmacology
11. The PMHNP knows the relationship between drug concentration and effect on 90 the
body is known as:
A. Pharmacology
B. Pharmacokinetics
C. Pharmacodynamics
D. Physiology
12. A patient who had previously reported feeling much better on her antidepressant
suddenly says the “drug seems to have stopped working. This is known as:
A. Tolerance
B. Tachyphylaxis
C. Side effect
D. Adverse effect
13. A medication that works by receptor activation to produce a biological response is
an:
A. Agonist
B. Enzyme inhibitor
C. Inverse agonist
D. Antagonist
14. A drug that binds to a receptor but does not fully activate it, producing a muted
biological response, is a(n):
A. Agonist
B. Enzyme inhibitor
C. Partial agonist
D. Antagonist
Revised Text with Enhanced Transition Words
- A drug that binds to the same receptor as an agonist, yet induces an opposite biological response, is classified as a(n) inverse agonist. In contrast, an antagonist blocks the receptor without triggering any biological activity. Therefore, it is crucial to differentiate between these two types of drugs, as they have distinct effects on the body.
- Moreover, a drug that effectively blocks receptors, thereby inhibiting a biological response, is referred to as a(n) antagonist. Additionally, it is important to note that a partial agonist can bind to the same receptor but only partially activates it, resulting in a muted biological response. Thus, understanding these classifications can significantly impact treatment decisions.
- Furthermore, one of the most common electrolyte abnormalities associated with the use of psychotropic medication is hyponatremia. In contrast, conditions such as hyperkalemia and hypercalcemia are less frequently observed in this context. It is essential for healthcare providers to monitor these electrolyte levels closely to ensure patient safety.
- When a patient who has been stable on his long-acting injectable medication expresses a desire to quit smoking, the best response is critical. For instance, one option could be, “I am glad you have decided to quit smoking.” However, it is also important to consider the practical aspects of this decision. Therefore, responding with, “Let us make an appointment as your medication dose may need to be lowered,” could be more appropriate to ensure proper management.
- Lastly, if a patient has been taking valproic acid for mood stabilization following a manic episode but still struggles with sleep, it raises concerns. His last drug level was noted to be 50 mcg/mL. Additionally, if the PMHNP observes that the patient appears disoriented to time and is flapping his wrists, it is crucial to take immediate action. Consequently, the PMHNP should assess the situation further to determine the next appropriate steps in management.? APA
