The nurse is preparing to administer a schedule II injectable drug and is drawing up half of the contents of a single-use vial. Which nursing action is correct?

Ask another nurse to observe and cosign wasting the remaining drug from the vial.

Keep the remaining amount in the patient’s drawer to give at the next dose.

Record the amount unused in the patient’s chart.

Dispose of the vial with the remaining drug into a locked collection box.

Answer and Explanation

The Correct Answer is A

A. Schedule II drugs are controlled substances with a high potential for abuse. Proper disposal requires a witness, usually another nurse, to verify and cosign the waste to ensure accountability and prevent diversion.

B. Keeping the remaining drug in the patient’s drawer is unsafe and violates controlled substance regulations. Single-use vials should not be stored for later use.

C. While documentation of administered medication is necessary, simply recording the unused amount in the patient’s chart is insufficient. Controlled substances require proper disposal with a witness.

D. Controlled substances cannot be discarded in a general locked collection box without proper witnessing and documentation. The correct procedure is to have another nurse verify and cosign the waste before disposal.

Correct Answer is B

Explanation

a) Decreased drug effects are unlikely in liver disease because impaired liver function reduces drug metabolism, leading to higher drug concentrations in the bloodstream.

b) Increased drug effects occur because the liver is responsible for metabolizing many drugs. In liver disease, drug metabolism is slowed, leading to prolonged drug action and potential toxicity.

c) Decreased therapeutic range is not the primary concern. The therapeutic range refers to the safe and effective drug concentration, but liver disease mainly affects drug metabolism and clearance.

d) Increased therapeutic range is incorrect because liver disease does not widen the range of safe drug levels; instead, it increases the risk of drug accumulation and toxicity.

A. Phase I B. Phase II C. Phase III D. Phase IV

Correct Answer is D

Explanation

a) Phase I studies focus on assessing the safety, dosing, and side effects of a drug in healthy volunteers, not its clinical effectiveness or potential new uses.

b) Phase II studies evaluate the drug's effectiveness and safety in a small group of patients with the targeted condition but do not focus on potential new uses.

c) Phase III studies are large-scale trials conducted to confirm the drug's effectiveness and safety before approval but do not typically involve studying new uses of the drug.

d) Phase IV studies occur after a drug has been approved and marketed. These studies, often called post-marketing surveillance, evaluate the drug's effectiveness and safety in the general population and investigate new potential uses or long-term effects.
