An interventional study of Peer-supported medication calculation training in Student and Nursing, sponsored by Lokman Hekim University. Completed at 1 site in Turkey (Türkiye). Open to participants aged 18 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2025-12-09.
Sponsored by Lokman Hekim University · Not applicable, Interventional, and Other
This experimental study aims to evaluate the effect of peer-assisted education on nursing students' numerical and drug calculation skills. A randomized controlled pretest-posttest design will be conducted with 55 first-year nursing students (27 in the experimental group and 28 in the control group). The experimental group will participate in a three-week peer education program focusing on numerical problem-solving and medication dosage calculations, led by trained mentor students.
Lokman Hekim University is the lead sponsor of 41 studies on the registry; 16 are open to participants now.

Participants who received traditional lecture-based instruction
The intervention consisted of a peer-supported education program on medication dosage calculation, implemented over three weeks with five 60-minute sessions. In Week 1, four mentor students-senior nursing students with prior training in medication calculations and a GPA above 3.0-received refresher instruction from the course instructor. The training covered decimals, percentages, unit conversions, weight-based and non-weight-based dose calculations, and infusion pump adjustments, followed by sample problem-solving activities. The intervention group was divided into four subgroups, each consisting of 7-8 students, and each was assigned a consistent mentor. Each session included 30 minutes of individual and peer problem-solving followed by 30 minutes of guided mentoring. The course instructor provided supervision and feedback throughout the sessions. During Weeks 2 and 3, students practiced numerical and medication dosage calculations through peer-supported exercises.
The Medication Calculation Ability
Medication Calculation Ability Assessment Form (Pre-Test, Post-Test): The pre-test consisted of eight questions. The posttest consisted of twenty questions, including additional questions similar to those in the pretest. The questions covered the following categories: * Dosage calculation for solid and liquid oral medications (3 questions in the pretest, 8 questions in the posttest), * Dosage calculation for injections (3 questions in the pretest, 7 questions in the posttest), * Calculation of percentage solutions and intravenous fluids (2 questions in the pretest, 5 questions in the posttest). Each correct answer was scored; the participants' correct answers were averaged to convert the score into a percentage. Thus, a medication calculation skill score ranging from 0% to 100% was obtained for each participant.
Time frame: They were evaluated before the intervention and after 3 weeks of intervention.
The Numerical Skills
Numerical Skills Assessment Form (Pre-Test, Post-Test): The pre-test consisted of five questions. The post-test consisted of 10 questions, including additional questions similar to those in the pre-test. The questions covered basic numerical skills, including addition, subtraction, multiplication, division, fractions, decimals, percentage calculations, and unit conversions. Each correct answer was scored, and the percentage score was converted by averaging the number of correct answers. Thus, a numerical skill score ranging from 0% to 100% was obtained for each participant.
Time frame: They were evaluated both before and after the 3-week intervention.
