should be discussed with the patient's provider in conjunction with other medications.

are regulated by the government and are determined to be safe.

aren't usually effective but are generally harmless.

Answer and Explanation

The Correct Answer is B

a) Herbs are not classified as medications under the Dietary Supplement Health and Education Act of 1994. The law classifies them as dietary supplements, which are not subject to the same rigorous safety and efficacy standards as medications.

b) Discussing herbal remedies with the patient's provider is essential. Herbs can interact with prescribed medications, and their safety and effectiveness can vary. It is important for providers to be aware of any herbal remedies the patient is using to avoid potential harmful interactions.

c) Herbs are not regulated by the government in the same way as pharmaceuticals. The FDA does not determine their safety before marketing, and manufacturers are not required to prove safety or efficacy before selling them.

d) Herbs are not harmless. Some herbs may be ineffective, but others can cause adverse effects, especially when taken alongside other medications. Therefore, it's important to consider their safety in the context of the patient’s overall treatment plan.

Correct Answer is A

Explanation

a) Bioavailability refers to the proportion of the drug that reaches systemic circulation when administered by a particular route. The oral route typically has lower bioavailability than the intravenous route due to the first-pass metabolism in the liver. Therefore, when switching from an IV form to an oral form, the dose often needs to be higher to achieve the same therapeutic effect.

b) Pinocytosis is a form of endocytosis where cells absorb fluids and small molecules. While important in drug absorption, it is not the reason why oral doses are higher than IV doses.

c) Tachyphylaxis is a rapid tolerance to a drug after its administration, often requiring higher doses over time, but it does not directly explain the need for a higher oral dose.

d) Protein binding refers to how drugs bind to proteins in the blood, which can affect their distribution. However, this is not the main reason why oral doses are higher than IV doses.

A. Applying the medication liberally B. Cleaning skin with alcohol before applying C. Using sterile technique D. Wearing gloves

Correct Answer is D

Explanation

a) Applying the medication liberally is incorrect because the amount of medication applied should be based on the prescribed dose. Overapplication can lead to excessive absorption and potential systemic effects.

b) Cleaning the skin with alcohol before applying the medication is not always necessary and can cause irritation. Some medications require specific preparation, but alcohol is not a universal requirement.

c) Using sterile technique is generally unnecessary for topical medication application unless the skin is broken or there is an open wound requiring sterility.

d) Wearing gloves is essential to prevent medication absorption through the nurse’s skin and to reduce the risk of contamination or infection.
