A patient who experiences motion sickness when flying asks the nurse the best time to take the medication prescribed to prevent motion sickness for a flight.
The nurse will instruct the patient to take the medication at what time?
As needed at the first sign of nausea.
When seated just prior to takeoff.
At 0830 just prior to boarding the flight.
At 0700 before leaving for the airport.
The Correct Answer is D
Choice A rationale
Taking medication at the first sign of nausea may be too late to prevent motion sickness as it takes time for the medication to be absorbed and take effect.
Choice B rationale
Taking medication just prior to takeoff might not give the drug enough time to be absorbed and start working effectively.
Choice C rationale
Taking medication just prior to boarding the flight may not provide sufficient time for the drug to reach its peak effectiveness.
Choice D rationale
Taking the medication at 0700 before leaving for the airport allows enough time for the drug to be absorbed and reach its peak effect, which is essential for preventing motion sickness during the flight.

Correct Answer is C
Explanation
Choice A rationale
The small intestine is where nutrients are absorbed, but it is not where vitamin D is activated. Vitamin D is first converted in the liver and then activated in the kidneys to promote calcium absorption.
Choice B rationale
This is incorrect because vitamin D is activated into a form that promotes calcium absorption. The active form is crucial for maintaining calcium and phosphate levels in the blood.
Choice C rationale
The kidneys play a significant role in converting vitamin D to its active form, calcitriol. This activated form is essential for the absorption of calcium in the intestines.
Choice D rationale
The large intestine is involved in water absorption and waste formation but not in the activation of vitamin D. The activation process primarily occurs in the kidneys and liver. .
Correct Answer is B
Explanation
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. .
