2024 PN NCLEX Questions Nursing Practice Question
Narrow therapeutic index medications:
Correct Answer: C
Rationale: Narrow therapeutic index (NTI) medications are characterized by a small margin between their minimum effective concentration and minimum toxic level, making careful monitoring crucial.
Option A is incorrect as NTI medications are known for significant pharmacokinetic variability, which can lead to adverse effects if not monitored closely. Option B is misleading; NTI drugs require frequent monitoring of blood levels to ensure safety and efficacy, contradicting the claim of having no monitoring needs. Option D is also wrong; NTI medications may have potent effects and significant side effects, emphasizing the importance of careful management rather than limited potency.
