Principles of Pharmacology Questions
Question 1 of 5
Labeling of herbal products is important. Which is an appropriate claim for an herbal product?
Correct Answer: B
Rationale: The correct answer is B: Helps increase blood flow to the extremities. This claim is appropriate because herbal products can indeed have vasodilatory effects that promote better blood circulation, potentially benefiting extremities. Choices A, C, and D make absolute claims that cannot be substantiated or guaranteed, making them inappropriate for labeling herbal products. Choice A oversimplifies the potential benefits and risks associated with diabetes prevention. Choice C falsely claims a cure for a complex and incurable condition like Alzheimer's disease. Choice D wrongly generalizes the safety of herbal products, as individual reactions can vary.
Question 2 of 5
The nurse is reviewing a patient’s list of drugs. The nurse understands that the older adult’s slower absorption of oral drugs is primarily because of which phenomenon?
Correct Answer: C
Rationale: The correct answer is C: Decreased gastric blood flow. In older adults, there is a decrease in gastric blood flow, which results in reduced absorption of oral drugs. This is due to age-related changes in the gastrointestinal system, leading to a decrease in blood flow to the stomach. This slowed blood flow affects the delivery of drugs to the site of absorption, resulting in slower absorption rates. Incorrect choices: A: Decreased cardiac output - While decreased cardiac output can affect overall drug distribution in the body, it does not directly impact the absorption of oral drugs in the stomach. B: Increased gastric emptying time - This would result in faster absorption, not slower absorption. D: Increased gastric acid secretion - While excessive gastric acid secretion can affect drug absorption, it does not explain the slower absorption in older adults.
Question 3 of 5
The nurse is developing teaching materials for an 82-year-old African American man with macular degeneration, who is being discharged on two new drugs. Which strategies would be best to use to impart the information? (Select all that apply.)
Correct Answer: A
Rationale: Step 1: Limiting distractions in the room is crucial for the elderly with impaired vision to focus on learning. Step 2: Macular degeneration affects visual acuity, making it essential to create an optimal learning environment. Step 3: Removing distractions enhances attention and retention of information. Step 4: Waiting until discharge is not ideal as it may lead to forgetfulness and lack of immediate clarification. Step 5: Augmenting teaching with audio material may not be effective if visual impairment affects hearing as well. Step 6: Using terms of familiarity like "Honey" may be inappropriate and disrespectful.
Question 4 of 5
Which treatments will the nurse anticipate administering to a patient who has been admitted with alcohol toxicity? (Select all that apply.)
Correct Answer: B
Rationale: The correct answer is B: Thiamine. Thiamine is essential in treating alcohol toxicity to prevent Wernicke-Korsakoff syndrome. Naloxone (A) is used for opioid overdose, not alcohol toxicity. Intravenous fluids (C) are given to treat dehydration but not specific to alcohol toxicity. Naltrexone (D) is used for alcohol dependence, not acute toxicity. Therefore, Thiamine is the most appropriate choice for treating alcohol toxicity.
Question 5 of 5
The Joint Commission recommends which of the following abbreviations for the “Do Not Use” list?
Correct Answer: A
Rationale: The correct answer is A: qd. The abbreviation "qd" is listed in the Joint Commission's "Do Not Use" list because it can be misinterpreted as "qd" (every day) or "qd" (every other day). This ambiguity can lead to dosing errors. Choice B: NPO is not recommended for the "Do Not Use" list by the Joint Commission. Choice C: Subling is not an abbreviation commonly associated with dosing instructions. Choice D: bid is a standard abbreviation for "twice a day" and is not on the "Do Not Use" list.
