Principles of Pharmacology Quizlet Questions
Question 1 of 5
The nurse researcher reviews the proposed informed consent form for a future clinical trial. The nurse expects to find which in the document? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A because the informed consent form should include a clear description of the benefits and risks associated with participating in the clinical trial. This information is crucial for participants to make an informed decision about their involvement. Option B is incorrect as it focuses on specific details rather than general benefits and risks. Option C is incorrect since outcomes are typically discussed after the trial, not in the initial informed consent form. Option D is incorrect as compensation details should not be included in the informed consent form to prevent coercion or inducement.
Question 2 of 5
The nurse will question the health care provider if a drug with a half-life ( t ½) of more than 24 hours is ordered to be given more than how often?
Correct Answer: A
Rationale: The correct answer is A: Once daily. A drug with a half-life of more than 24 hours takes longer to be eliminated from the body. To maintain therapeutic levels and avoid accumulation, the drug should be given less frequently than its half-life. Giving it once daily ensures a consistent level in the body. Choices B, C, and D are incorrect because they are less frequent dosing intervals than once daily, which could lead to subtherapeutic levels or accumulation of the drug.
Question 3 of 5
The nurse is aware that the rate of absorption can be changed by which actions? (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: Modifying gastric emptying time. Gastric emptying time affects the rate at which drugs are absorbed in the body. Slowing down or speeding up gastric emptying can alter the absorption rate of drugs. Changing gastric pH (choice B) can affect drug solubility but not necessarily absorption rate. Decreasing inflammation (choice C) may impact drug distribution but not absorption. Forming drug complexes (choice D) can affect drug stability but not absorption rate. Therefore, the correct answer is A as it directly influences the rate of drug absorption.
Question 4 of 5
The nurse is describing to a patient the synergistic effects of two of his medications. Which statement by the nurse is correct about synergistic drug effects?
Correct Answer: D
Rationale: The correct answer is D: A greater effect is achieved when two drugs are combined. Synergistic effects occur when two drugs work together to produce a greater effect than when used individually. This can lead to enhanced therapeutic benefits or increased side effects. Choice A is incorrect as antagonistic effects refer to drugs that counteract each other's effects. Choice B is incorrect as drug nullification occurs when one drug cancels out the effects of another. Choice C is incorrect as an antidote reverses the effects of a specific drug, not enhances its effects when combined with another.
Question 5 of 5
What provisions of the Dietary Supplement Health and Education
Correct Answer: A
Rationale: The correct answer is A because the Dietary Supplement Health and Education Act of 1994 is most important for nurses in terms of understanding regulations related to patient health teaching. This act outlines requirements for supplement labeling, safety, and efficacy information, ensuring that nurses can provide accurate information to patients. Choices B, C, and D are incorrect as they do not directly relate to the importance of the act for nurses in patient education. B clarifies marketing regulations, C reclassifies herbs, and D addresses marketing of herbal products, but they do not specifically focus on the nurse's role in patient education.
