Final answer:
The medical assistant demonstrated the 'Right time' of medication administration by ensuring the medication is given at an optimal time after the patient has eaten to avoid interactions that could affect drug effectiveness or increase toxicity.
Step-by-step explanation:
A medical assistant asking a patient when they last ate before administering a medication that should be taken at least two hours after a meal is demonstrating the Right time of medication administration. This is one of the critical 'rights' to ensure patient safety and the effectiveness of the medication. Factors like the half-life of the drug, the route of administration, dosage, patient's age, and specific time instructions like the one under consideration are crucial in determining the Right time to administer medication to a patient.
When considering dosage and route of administration, it's important to select the optimum dosage to minimize the risk of side effects while achieving clinical cure. For patients with liver or kidney dysfunction, reduced drug metabolism or clearance can lead to toxicity, making it even more critical to adhere to timing instructions. Similarly, knowing whether a drug's effectiveness is dose dependent or time dependent also influences the time at which it's administered.
In the context of Right time, the objective is to optimize therapeutic drug levels at the site of infection, without causing significant toxicity, by giving the medication at times that align with its pharmacokinetics and the patient's needs.
