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. .

Related Questions
Correct Answer is C
Explanation
Choice A rationale
Class I antiarrhythmic drugs block sodium channels, affecting phase 0 of the action potential, not phase 3.
Choice B rationale
Class IV antiarrhythmic drugs block calcium channels, which affects phase 2 of the action potential and slows heart rate and conduction.
Choice C rationale
Class III antiarrhythmic drugs block potassium channels, prolonging phase 3 of the action potential. This results in a prolonged repolarization period, reducing the risk of arrhythmia.
Choice D rationale
Class II antiarrhythmic drugs are beta-blockers that primarily affect phase 4 of the action potential, reducing heart rate and conduction, but they do not block potassium channels.
Correct Answer is D
Explanation
Choice A rationale
The Drug Enforcement Agency (DEA) primarily focuses on the enforcement of controlled substances laws and regulations, not the approval and testing of medications.
Choice B rationale
The Joint Commission on Accreditation of Healthcare Organizations (JCAHO) accredits and certifies healthcare organizations and programs, but it does not control medication testing.
Choice C rationale
The Centers for Disease Control and Prevention (CDC) focuses on public health and disease prevention, not the scientific testing of medications.
Choice D rationale
The Food and Drug Administration (FDA) is responsible for protecting public health by ensuring the safety, efficacy, and security of human and veterinary drugs, biological products, and medical devices through rigorous scientific testing. .
