Extract:
Question 1 of 5
Which law(s) govern all drug administration by nurses?
Correct Answer: C
Rationale: The correct answer is C: Nurse Practice Acts. Nurse Practice Acts are state laws that regulate nursing practice, including drug administration. These acts outline the scope of nursing practice, including the administration of medications. The other choices are incorrect because: A is specific to drug regulation, B is related to FDA regulations, and D focuses on controlled substances, not all drugs. Overall, Nurse Practice Acts are the most comprehensive and directly relevant laws governing drug administration by nurses.
Question 2 of 5
What concept is considered when generic drugs are substituted for brand-name drugs?
Correct Answer: A
Rationale: The correct answer is A: Bioavailability. Bioavailability refers to the rate and extent at which the active ingredient in a drug is absorbed and becomes available at the site of action. When generic drugs are substituted for brand-name drugs, it is crucial to ensure that they have the same bioavailability to produce the same therapeutic effect. Critical concentration, distribution, and half-life are important pharmacokinetic concepts but are not directly related to the substitution of generic drugs. Critical concentration is the amount of drug needed to produce a therapeutic effect, distribution refers to the movement of drugs within the body, and half-life is the time it takes for the drug concentration to decrease by half in the body.
Question 3 of 5
The nurse is developing a teaching plan for an elderly patient who will begin taking an antihypertensive drug that causes dizziness and orthostatic hypotension. Which nursing diagnosis is appropriate for this patient?
Correct Answer: D
Rationale: The correct answer is D: Risk for injury related to side effects of the medication. This nursing diagnosis is appropriate because the patient is at risk for injury due to the potential side effects of dizziness and orthostatic hypotension from the antihypertensive drug. The nurse should assess the patient's risk factors, provide education on fall prevention, and implement interventions to minimize the risk of injury.
Choice A is incorrect because it focuses solely on knowledge deficit without addressing the actual risk for injury.
Choice B is incorrect as it generalizes health maintenance issues to age without addressing the specific medication side effects.
Choice C is incorrect as it assumes the patient is ready for enhanced knowledge without first addressing the risk for injury.
Question 4 of 5
The nurse is preparing to administer an oral medication and wants to ensure a rapid drug action. Which form of the medication will the nurse administer?
Correct Answer: C
Rationale: The correct answer is C: Liquid suspension. A liquid suspension form of medication will lead to a rapid drug action compared to other forms. This is because liquid suspensions are already in a partially dissolved state, allowing for quicker absorption and onset of action. Capsules, enteric-coated pills, and tablets all need to be broken down in the gastrointestinal tract before absorption can occur, which can delay the drug action. Liquid suspensions are also easier to swallow, making them ideal for patients who have difficulty swallowing solid dosage forms. In summary, liquid suspensions provide faster drug action due to their pre-dissolved state and ease of administration compared to capsules, enteric-coated pills, and tablets.
Question 5 of 5
A patient is prescribed a medication and asks the nurse if the drug is available in a generic form. The nurse understands that a generic medication will have a name that (select all that apply):
Correct Answer: C,D
Rationale: The correct answer is C and D.
Choice C is correct because generic medications typically have names that describe the drug's chemical structure, making it easier to identify the active ingredient.
Choice D is correct because generic medications are non-proprietary, meaning they are not brand-name drugs and do not have exclusive rights or trademarks associated with them.
Choices A, B, and E-G are incorrect.
Choice A is incorrect because generic medications do not have registered trademarks.
Choice B is incorrect because generic medication names are not always capitalized.
Choice E-G are not applicable as they are not provided in the question or do not align with the characteristics of generic medications.
In summary, generic medication names are based on the drug's chemical structure and are non-proprietary, distinguishing them from brand-name medications.
