Principles of Pharmacology Quizlet Questions
Question 1 of 5
Which of the following variables is a factor in drug absorption?
Correct Answer: B
Rationale: The correct answer is B: A rich blood supply to the area of absorption leads to better absorption. A rich blood supply enhances drug absorption by allowing for faster diffusion of the drug into the bloodstream. This is because a greater blood flow increases the concentration gradient, facilitating quicker absorption. Explanation for why the other choices are incorrect: A: The statement that the smaller the surface area for absorption, the more rapidly the drug is absorbed is incorrect. Larger surface area typically leads to faster absorption due to increased contact with absorbing surfaces. C: The statement that the less soluble the drug, the more easily it is absorbed is incorrect. Solubility affects dissolution, not absorption. D: The statement that ionized drugs are easily absorbed across the cell membrane is incorrect. Ionized drugs have lower permeability across cell membranes compared to non-ionized drugs.
Question 2 of 5
The nurse is developing goals in collaboration with a patient. Which is the best goal statement?
Correct Answer: C
Rationale: The correct answer is C because it is specific, measurable, achievable, relevant, and time-bound (SMART). It clearly states the goal of independently self-administering the prescribed dose of albuterol by the end of the second teaching session. This goal is clear and concrete, allowing for easy evaluation of progress. Choice A is not the best because it lacks specificity regarding independence. Choice B lacks the clarity of when the goal should be achieved. Choice D is irrelevant to the specific task of self-administering albuterol. In summary, choice C is the best goal statement as it meets the criteria of a well-defined and achievable goal in collaboration with the patient.
Question 3 of 5
The Nursing Alliance for Quality Care’s focus is for health care providers to strive for which goal?
Correct Answer: C
Rationale: The correct answer is C: Development of a patient relationship/family engagement. The Nursing Alliance for Quality Care aims to promote patient-centered care, which includes building strong relationships with patients and engaging their families in the care process. This approach leads to better health outcomes and patient satisfaction. Choice A focuses on medication safety, which is important but not the primary goal of the alliance. Choice B highlights confidentiality, which is crucial but doesn't capture the alliance's main focus. Choice D emphasizes patient independence within the family, which is not directly related to the alliance's goal of patient-centered care.
Question 4 of 5
The clinical research nurse knows that only a small proportion of drugs survive the research and development process. An appreciation of the process and associated costs grows when the nurse is aware that approximately one in how many potential drugs is approved by the US Food and Drug Administration?
Correct Answer: B
Rationale: The correct answer is B: 1000. The approval rate by the FDA is around 1 in 1000 potential drugs. This means that out of a large number of drug candidates, only a very small percentage actually make it through the rigorous research and development process to receive FDA approval. Choice A (100) is too low and would imply a much higher approval rate. Choices C (10,000) and D (100,000) are too high, suggesting an even lower approval rate, which is not the case based on industry standards. Thus, the most accurate representation of the approval rate is 1 in 1000, making option B the correct answer.
Question 5 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.
