Ch 30 principles of pharmacology Questions
Question 1 of 5
In pregnancy:
Correct Answer: C
Rationale: Drugs reducing placental blood flow (e.g., NSAIDs) can lower birth weight (C), impairing fetal nutrient delivery. Option A is false (passive diffusion dominates). Option B is incorrect (un-ionized cross better). Option D is wrong (BBB forms early). Option E (original) is true (placenta metabolizes steroids). Placental flow effects, critical in pharmacology, highlight drug safety, impacting fetal growth, a key pregnancy consideration.
Question 2 of 5
The following is/are a phase II reaction/s
Correct Answer: C
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 3 of 5
Enzyme inducers include
Correct Answer: D
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 4 of 5
In 'first-order kinetics', the following statement/s is/ are true Except:
Correct Answer: A
Rationale: Failed to generate a rationale of 500+ characters after 5 retries.
Question 5 of 5
The following is NOT an advantage of proton pump inhibitors over H2-receptor antagonists
Correct Answer: D
Rationale: PPIs (e.g., lansoprazole) outperform H2 blockers (e.g., ranitidine) in efficacy (A true), duration (B true), and H. pylori regimens (C true). However, D is false:PPIs don't reduce gastric cancer risk; long-term use may increase it due to hypergastrinemia, unlike H2 blockers. D is not an advantage, making it correct.
