After completing a course on pharmacology for nurses, what will the nurse know?
Everything necessary for safe drug administration.
General drug information; the nurse can consult a drug guide for specific drug information.
The drug actions that are associated with each classification of medication.
Current pharmacologic therapy; the nurse will not require ongoing education for 5 years.
The Correct Answer is B
Choice A rationale
Knowing everything necessary for safe drug administration would imply complete knowledge and expertise, which is an unrealistic expectation for any nurse after just one course. Safe drug administration requires continuous learning and staying updated with new guidelines, drug interactions, and patient-specific factors.
Choice B rationale
General drug information includes understanding drug classes, mechanisms of action, and common side effects. Nurses can consult a drug guide for specific information such as dosage, contraindications, and interactions. This approach ensures they can safely and effectively administer medications while remaining adaptable to new drugs and evolving guidelines.
Choice C rationale
Understanding drug actions associated with each classification of medication is crucial, but it is only one aspect of pharmacology. Nurses also need to know about side effects, contraindications, and patient-specific considerations. Comprehensive drug knowledge requires ongoing education and consultation of reliable resources.
Choice D rationale
Current pharmacologic therapy knowledge is essential, but it is not static. Medical and pharmaceutical fields are constantly evolving, with new drugs, research, and guidelines emerging regularly. Nurses must engage in ongoing education to maintain their competence and provide the best care for their patients. .

Correct Answer is D
Explanation
Choice A rationale
This choice is incorrect. A complete occlusion of a coronary vessel results in a myocardial infarction (heart attack), not unstable angina. Unstable angina occurs when there is a significant narrowing or partial blockage of a coronary artery, leading to reduced blood flow and oxygen supply to the heart muscle, causing pain or discomfort. Complete occlusion would cause permanent damage to the heart muscle, which is not the case with unstable angina.
Choice B rationale
This choice is correct. While unstable angina is mainly caused by narrowing of the coronary arteries, it can also be caused by a spasm of the blood vessel. This spasm, also known as vasospasm, reduces the amount of blood flow to the heart muscle, resulting in pain. These spasms can occur even if the coronary arteries do not have significant plaque buildup, adding another layer of complexity to the condition.
Choice C rationale
This choice is partially correct. The body’s response to a lack of oxygen (ischemia) in the heart muscle does result in pain, known as angina. However, this choice does not fully capture the specific nature of unstable angina, which involves episodes of pain that occur more frequently and are more severe than those associated with stable angina, and can occur at rest or with minimal exertion, indicating a higher risk for a heart attack.
Choice D rationale
This choice is correct. Unstable angina is characterized by a serious narrowing of a coronary artery that reduces oxygen supply to the heart. This narrowing is typically due to atherosclerotic plaque and can be complicated by blood clots or spasms. Unlike stable angina, the pain of unstable angina is more unpredictable and can occur without a triggering factor like exercise or stress, signaling a higher risk of a heart attack.
Correct Answer is D
Explanation
Choice A rationale
The half-life of a drug refers to the time it takes for the plasma concentration of a drug to reduce by half. It is not a primary consideration when substituting generic drugs for brand-name drugs.
Choice B rationale
Critical concentration is the amount of a drug needed to achieve therapeutic effects. While important, it is not the main factor in generic substitution.
Choice C rationale
Distribution describes how a drug is dispersed throughout the body's tissues and fluids. This factor is crucial for drug efficacy but not directly related to substituting generic drugs.
Choice D rationale
Bioavailability is the degree and rate at which an active drug ingredient is absorbed and becomes available at the site of action. Generic drugs must have the same bioavailability as brand-name drugs to ensure they are just as effective.
