- B.
Medications given orally bypass the portal circulatory system.
- C.
A large percentage of an intravenously administered drug is metabolized into inactive metabolites in the liver.
- D.
Drugs administered intravenously enter the portal system prior to systemic distribution.
Correct Answer
A. Medications given intravenously are not affected by the first-pass effect.Explanation
The nurse will draw on their knowledge of pharmacokinetics to respond to the patient. The first-pass effect refers to the metabolism of a drug that occurs in the liver before it reaches systemic circulation. When a medication is given orally, it must pass through the liver first, which can result in a significant portion of the drug being metabolized and therefore reducing its effectiveness. However, medications given intravenously bypass the liver and are directly delivered into the bloodstream, avoiding the first-pass effect. This allows for a more potent and predictable effect compared to oral administration.Rate this question:

Specific medications are classified as "high-alert" because they have a higher potential for causing harm to patients. These medications may have a narrow therapeutic index, meaning that the difference between a therapeutic dose and a toxic dose is small. They may also have a higher risk of adverse effects, drug interactions, or medication errors. Therefore, healthcare providers need to exercise extra caution when prescribing, dispensing, and administering these medications to minimize the risk of harm to patients.Rate this question:

This is important because herbs can have potential interactions with prescribed medications, which can lead to adverse effects or reduce the effectiveness of the medication. It is crucial for patients to consult their healthcare provider to ensure the safe and effective use of herbs alongside their prescribed medications. Understanding the use of herbs, reading directions and labels, and stopping the use of herbs if adverse effects are noted are also important, but confirming interactions with prescribed medications takes priority.Rate this question:
