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 C
Explanation
Choice A rationale
Anticholinergic drugs do not cause pupil restriction; they relax the muscles around the eye, leading to dilation.
Choice B rationale
Decreased lacrimal secretions are a secondary effect of anticholinergics and not their primary purpose in ophthalmology.
Choice C rationale
Anticholinergics cause pupil dilation (mydriasis) by relaxing the muscles that constrict the pupil, allowing for a better examination of the eye's interior.
Choice D rationale
Sedation is not a primary effect of anticholinergics used in ophthalmology.
Correct Answer is A
Explanation
Choice A rationale
Oral morphine typically reaches peak activity at around 45 minutes after administration. This allows time for the medication to be absorbed through the gastrointestinal tract and enter the bloodstream to provide pain relief.
Choice B rationale
10 minutes is too short for oral morphine to reach peak activity. This timeframe is more consistent with intravenous administration, which allows for rapid onset of action.
Choice C rationale
30 minutes is a bit too short for oral morphine to reach peak effect, although some patients may start to feel relief. However, peak plasma concentrations generally occur closer to 45-60 minutes.
Choice D rationale
While morphine can continue to have effects up to 60 minutes and beyond, the peak activity is typically observed around the 45-minute mark. Waiting for 60 minutes may underestimate the peak timeframe.
