Before marketing a new drug that has been approved for use based on clinical effectiveness and safety, the manufacturer wishes to study the potential new uses for the drug. This is an example of which phase of study?
Phase I
Phase II
Phase III
Phase IV
The Correct Answer is D
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.

Correct Answer is B
Explanation
A. Washing hands before handling medications is essential for infection control but is not the priority action in this scenario. Ensuring drug compatibility is crucial to prevent adverse interactions.
B. When administering two drugs simultaneously, the nurse’s priority is to determine if they are compatible, particularly for IV medications. Some medications can precipitate or cause harmful interactions when mixed, leading to reduced efficacy or adverse effects. Consulting a drug guide ensures safe administration.
C. Checking for drug allergies is important before giving any medication, but it is not the priority in this specific situation. Compatibility must be assessed first to ensure the drugs can be given together safely.
D. Identifying the patient is always necessary for safe medication administration, but in this case, ensuring drug compatibility is the first step before proceeding with administration. If the drugs are incompatible, the nurse must take alternative actions before giving them to the patient.
Correct Answer is B
Explanation
a) Assessment involves gathering and analyzing data about the patient, such as their living situation, memory issues, and medication regimen, but it does not include developing a strategy to address these concerns.
b) Planning is the phase where the nurse develops interventions to help the patient manage their medications safely. By creating a medication chart and involving a family member, the nurse is ensuring adherence to the prescribed regimen.
c) Evaluation occurs after implementation to assess the effectiveness of the plan, such as checking if the patient is taking the medications correctly.
d) Implementation involves carrying out the planned interventions, such as physically setting up the pill organizer or educating the patient on medication use.
