LVN Pharmacology & Medication Administration

Question 1

What is the primary route of drug administration that ensures 100% bioavailability?

Accepted Answer

Intravenous

Answer

Intravenous (IV) administration ensures 100% bioavailability because the drug is delivered directly into the bloodstream, bypassing any absorption barriers. This means the entire dose immediately enters systemic circulation, making it the fastest and most complete route for drug delivery.

Question 2

Which organ is primarily responsible for metabolizing medications?

Accepted Answer

Liver

Answer

The liver is the primary organ responsible for metabolizing (breaking down) most medications through various enzymatic processes. This detoxification process converts drugs into more water-soluble forms, facilitating their excretion from the body and preventing accumulation of active drug.

Question 3

What does the 'five rights' of medication administration include?

Accepted Answer

Right patient, drug, dose, route, and time

Answer

The 'five rights' of medication administration are fundamental safety checks designed to prevent medication errors. Ensuring the right patient receives the right drug, in the right dose, via the right route, at the right time significantly reduces the risk of harm and promotes patient safety.

Question 4

Which of the following is considered a high-alert medication?

Accepted Answer

Insulin

Answer

Insulin is considered a high-alert medication because it carries an increased risk of causing significant patient harm when used in error. Errors with insulin, such as incorrect dosing, can lead to severe hypoglycemia or hyperglycemia, which can be life-threatening.

Question 5

Why is it important to review a patient's allergies before administering medication?

Accepted Answer

To avoid adverse reactions

Answer

Reviewing a patient's allergies before administering medication is critically important to prevent severe adverse reactions, including anaphylaxis, which can be life-threatening. This crucial step ensures patient safety by avoiding exposure to known allergens and selecting appropriate alternative medications.
