Principles of Pharmacology Questions
Question 1 of 5
Which of the following substances is the most likely to be absorbed in the intestines rather than in the stomach?
Correct Answer: D
Rationale: The correct answer is D, Glucose. Glucose is a small molecule that is primarily absorbed in the small intestine through active transport mechanisms, where most nutrient absorption occurs. The small intestine has a larger surface area and more specialized transport mechanisms for nutrient absorption compared to the stomach. A, Sodium bicarbonate, is mainly absorbed in the stomach as it helps neutralize stomach acid. B, Ascorbic acid, is primarily absorbed in the stomach and the small intestine. C, Salicylic acid, is absorbed in the stomach and upper small intestine. Therefore, D is the most likely substance to be absorbed in the intestines rather than the stomach.
Question 2 of 5
During a medication review session, a patient states, “I do not know why I am taking all of these pills.” Based on this piece of subjective data, which problem will the nurse identify?
Correct Answer: B
Rationale: The correct answer is B: Knowledge. The patient's statement indicates a lack of understanding about their medications. This can lead to non-adherence, mismanagement, or harm. Pain (A), fatigue (C), and anxiety (D) are not directly related to the patient's lack of knowledge about their medications. Pain and fatigue may be addressed separately, while anxiety may be a result of the patient's confusion but is not the primary issue identified by the nurse in this scenario.
Question 3 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 4 of 5
The research nurse is meeting with a patient and determines, based on the assessment, that the patient meets inclusion criteria for clinical research. The patient agrees to participate in the clinical trial. The nurse advises the patient that which member of the health care team has the responsibility to explain the study and respond to questions?
Correct Answer: D
Rationale: The correct answer is D: Health care provider. The health care provider, typically the physician or principal investigator, is responsible for explaining the study details and addressing any questions the patient may have. As the primary individual overseeing the patient's care and treatment, the health care provider is best equipped to provide comprehensive information about the research study. Registered nurses (choice A) may assist in conveying information, but the ultimate responsibility lies with the health care provider. Pharmacists (choice B) play a crucial role in medication management but are not typically involved in explaining research studies. Research associates (choice C) may aid in study coordination but do not have the same level of medical expertise as the health care provider.
Question 5 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.
