Basic Principles of Pharmacology Quizlet Questions
Question 1 of 5
Which of the following permeation processes mediated the man's intestinal absorption of ethanol?
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 2 of 5
Which of the following terms best defines a beta-blocker that binds reversibly to beta receptors?
Correct Answer: D
Rationale: A noncompetitive antagonist best defines a beta-blocker that binds reversibly to beta receptors because it binds to a site on the receptor that is not the same as the agonist binding site, thereby preventing the receptor from being activated by the agonist. This type of antagonist does not compete with the agonist for binding to the receptor, making it an effective blocker of receptor activation. In this case, the drug had no intrinsic activity and only bound reversibly to beta receptors, indicating its role as a noncompetitive antagonist.
Question 3 of 5
Which of the following terms best defines this tolerance pattern where the first cigarette of the day causes tachycardia?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
This patient's disease was most likely mediated by genetic polymorphism of which of the following enzymes?
Correct Answer: B
Rationale: Glucose-6-phosphate dehydrogenase (G6PD) deficiency is associated with hemolytic anemia triggered by certain drugs like chloroquine. The patient's presentation with hemolytic anemia after chloroquine treatment suggests a G6PD deficiency, making it the most likely enzyme involved in this patient's disease.
Question 5 of 5
What percentage of the drug valproic acid is most likely lipid soluble in the patient's duodenal lumen?
Correct Answer: B
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
