A nurse is caring for a patient who is supposed to receive two drugs at the same time. What is the nurse's priority action?

Wash her hands before handling the medications.

Consult a drug guide for compatibility.

Question the patient concerning drug allergies.

Answer and Explanation

The Correct Answer is B

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 A

Explanation

a) Phase III clinical trials involve large groups of human participants and focus on confirming the drug's effectiveness and monitoring for adverse effects. The nurse plays a key role in observing and documenting any side effects experienced by the patients.

b) Working with animals is part of preclinical trials, not phase III studies. By the time a drug reaches phase III, it has already undergone animal testing.

c) While data collected in phase III trials contribute to determining a drug’s effectiveness, the decision-making is primarily done by researchers and regulatory agencies, not individual nurses.

d) Selection of appropriate clients for a drug study is generally determined by researchers and trial coordinators based on inclusion and exclusion criteria, rather than by nurses directly.

A. Duration of action. B. Onset of action. C. Peak action time. D. Time response curve.

Correct Answer is B

Explanation

A. Duration of action refers to the length of time a drug remains effective after reaching the MEC, but it does not describe the time required to reach this threshold.

B. Onset of action is the time it takes for a drug to reach the minimum effective concentration (MEC) and begin producing a therapeutic effect. This is influenced by factors such as drug absorption and distribution.

C. Peak action time refers to the time at which the drug reaches its highest concentration in the bloodstream, not the time required to reach the MEC.

D. The time response curve is a graphical representation of a drug's effects over time but does not specifically define the time needed to reach the MEC.
