Principles of Pharmacology Quizlet Questions
Question 1 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 2 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 3 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.
Question 4 of 5
A 4-year-old patient is discharged on an oral liquid drug suspension of 4
Correct Answer: D
Rationale: The correct answer is D: Household teaspoon. A household teaspoon is commonly found in most households, making it convenient for caregivers to use for administering oral liquid medications accurately. It is important to use a standardized measuring device like a household teaspoon to ensure the correct dosage is given. Measuring spoons and graduated medicine cups may vary in accuracy and are not as commonly available in households as household teaspoons, increasing the risk of dosage errors. Using these alternatives may lead to under or overdosing the medication, posing a risk to the child's health. Therefore, the household teaspoon is the most suitable option for accurate home administration of the drug.
Question 5 of 5
The Principle of Atraumatic Care includes: (Select all that apply.)
Correct Answer: A
Rationale: The correct answer is A: Pain management. The Principle of Atraumatic Care focuses on minimizing physical and psychological distress during healthcare procedures. Pain management is essential to promote comfort and reduce trauma for the patient. Choice B, collaborative care with family members, is important for holistic care but not directly related to atraumatic care. Choice C, glomerular filtration rate, is a measure of kidney function and not relevant to atraumatic care. Choice D, flashbacks from LSD use, is unrelated to atraumatic care and pertains to substance abuse issues. Therefore, the correct answer is A as it aligns with the principles of reducing trauma and promoting comfort during healthcare procedures.
