Senior nurses use diverse strategies for drug calculations, focusing more on understanding the problem than solving it. Nurse educators should ensure calculation questions reflect real clinical scenarios.
Area of Science:
- Nursing Education
- Cognitive Psychology
- Pharmacology
Background:
- Accurate drug calculations are critical for patient safety in nursing.
- Understanding the cognitive processes behind drug calculation is essential for effective teaching.
Purpose of the Study:
- To investigate the cognitive strategies senior nurses employ when solving written drug calculation problems.
- To identify the key cognitive steps involved in nurse-led drug dosage calculations.
Main Methods:
- Utilized verbal protocol methodology with eight senior nurses in an educational setting.
- Employed verbal protocol analysis to examine the cognitive processes during problem-solving.
Main Results:
- Nurses employed a variety of strategies beyond the standard nursing formula.
- Cognitive processes revealed a significant emphasis on problem representation over direct calculation.
- A majority of cognitive steps were dedicated to interpreting and structuring the problem.
Conclusions:
- Nurse educators must prioritize teaching problem representation skills for drug calculations.
- Assessment questions for drug calculations should closely mirror authentic clinical practice scenarios.
- Improving problem representation can enhance nurses' accuracy in medication dosage calculations.
