Principles of Pharmacology Questions
Question 1 of 5
When developing an individualized medication teaching plan, which topics will the nurse include? (Select all that apply.)
Correct Answer: A
Rationale: Rationale: A is correct because adherence to the prescribed drug regimen is crucial for treatment success. It ensures the patient takes the right dose at the right time. B is incorrect as different drugs may have different routes of administration. C is incorrect as not all side effects need to be reported. D is incorrect as doubling a missed dose can be dangerous and should not be advised.
Question 2 of 5
The foundation of clinical trials, Good Clinical Practice, is a helpful resource for nurses. The nurse is correct in choosing Good Clinical Practice as a reference for standards in which areas? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: Design. Good Clinical Practice (GCP) provides guidelines for the design of clinical trials to ensure ethical conduct, data integrity, and participant safety. It covers aspects such as study protocol development, participant selection, and informed consent procedures. Monitoring and auditing (B) are also covered by GCP, but they focus on oversight rather than design. Analyses (C) and reporting (D) are more related to data management and interpretation, which are not the primary focus of GCP's design guidelines. Therefore, the nurse should choose GCP as a reference for standards in the design of clinical trials.
Question 3 of 5
The nurse is reviewing a patient’s list of medications and notes that several have the highest abuse potential. According to US standards, the highest potential for abuse of drugs with accepted medical uses is found in drugs included in which schedule?
Correct Answer: A
Rationale: The correct answer is A: II. Schedule II drugs in the US have the highest potential for abuse among drugs with accepted medical uses. This is because they have a high potential for psychological and physical dependence. These drugs have strict regulations for prescribing and dispensing to minimize the risk of abuse. Schedule III, IV, and V drugs have lower abuse potential compared to Schedule II drugs. Schedule III drugs have a moderate to low potential for abuse, while Schedule IV and V drugs have even lower potential for abuse and are considered to have accepted medical uses with lower risk of dependence.
Question 4 of 5
Which components of pharmacokinetics does the nurse need to understand before administering a drug? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A because drugs with a smaller volume of distribution tend to stay in the bloodstream longer, leading to a longer half-life. This is important for determining dosing intervals. Option B is incorrect because oral drugs are usually absorbed through passive diffusion or active transport, not pinocytosis. Option C is incorrect because patients with kidney disease may actually have more protein-binding sites, leading to potential drug accumulation. Option D is incorrect because rapid absorption typically increases the bioavailability of the drug, not decreases it.
Question 5 of 5
A Native American patient is newly diagnosed with type 2 diabetes mellitus and is prescribed the antidiabetic drug metformin 500 mg by mouth with morning and evening meals. Which statement best indicates to the nurse that the patient will adhere to the therapeutic regimen?
Correct Answer: A
Rationale: The correct answer is A because it demonstrates understanding of the importance of dietary modifications in managing diabetes. By stating "I will no longer put sugar on my cereal because that will help me be healthier," the patient shows a willingness to make lifestyle changes to improve their health. This indicates a commitment to adhering to the prescribed treatment plan. Choice B is incorrect because it suggests the patient expects immediate relief and may stop taking the medication prematurely. Choice C is incorrect as it focuses on fear-based motivation rather than understanding the benefits of medication adherence. Choice D is incorrect as it reflects a fatalistic attitude that may hinder the patient's engagement in self-care.
