Application of generalizability theory in the examination of introduction of nursing / 中国实用护理杂志

Objective To analysis the reliability of the examination of Introduction of Nursing by using the methods of generalizability theory and to give advice on how to modify examination paper.Methods Estimation value of variance component from different variations and precision indexes were calculated by applying the principle of generalizability theory.Results The generalizability coefficient and index of dependability were greater than 0.4 in choice question and terminology explanation,the generalizability coefficient of short-answer question was also greater than 0.4.Short-answer question's index of dependability and generalizability coefficient and index of dependability of comprehensive problem were less than 0.4.Conclusions Generalizability theory can be used in analysis the reliability of the examination of Introduction of Nursing.Its result is helpful to improve the framework of examination papers and the reliability of examination.

The evaluation of multi-project assessment of fundamental nursing skills / 中国实用护理杂志

Objective To illustrate the different levels of fundamental nursing skills of undergradu ate nursing students,and explore the characteristics of the assessment method.Methods With descriptive statistics,one-way analysis of variance after rank transformation,and multiple comparison (Scheffe),we made an analysis of 1 340 assessment records of fundamental nursing skills.Results The score distributions of all the skills,but the skill of measuring vital signs,conformed to Gaussian distribution.The overall distribution shaped in peak state and was negative skewness,showing bias towards 70 to 90 score levels.The score levels of 60 and 70 were significantly higher than that of their surrounding levels.The scores of aspiration of sputum,oxygenic therapy and aseptic technique were the lowest,while the scores of closed bed making and intramuscular injection were the highest.Conclusions The score distribution of fundamental nursing skills is rational,which shows the methods of teaching and assessment are generally believable.But the individual bias cannot be ignored.The majority of students get high grades.Different levels do exist among different skills because of abstract or concrete characteristics and principal matters.

An application of the S-P Chart analysis in examination item exam on fundamental nursing / 中国实用护理杂志

Objective To obtain a two-dimensional evaluation result of the quality of examination paper on fundamental nursing and the students' performance,so as to find the weakness and problems in teaching and learning,and to put forward some suggestions.Methods With the S-P chart analytic system which was designed by using the technology of Excel VBA,we made an analysis of 164 papers of fundamental nursing.Results Both the P-curve and S-curve were in the lower right corner.There wasn't any long vertical line in P-curve.There wasn't any long horizontal one in S-curve either.Caution index of 4 questions and 15 students exceed 0.75.The totality difficulty index of the paper was 0.79.The suitability index was 0.43.The stability index was 0.48.Conclusions Propositional contents about physician orders management,gastric lavage,administering medication,observation of disease and pain need to be reformed into both wide coverage and clear focuses.There are no faults in students' grades.Different learning levels do exist,but with little difference.S-P chart affords multiplex and huge amount of information.Its graphics and parameters help to analyze both the students' and teachers' performance from the macroscopic and microcosmic angle,so as to make teachers self-reflective on teaching fundamental nursing and producing papers from various aspects.

CT findings of melamine caused urinary calculi / 中华放射学杂志

Objective To analyze the CT findings of melamine induced urinary calculi.Methods Nineteen children with a history of ingestion of melamine contaminated infant formula milk were studied, including 12 males and 7 females, age ranged from 50 days to 5 years.Results CT demonstrated renal pelvic and ureteral stones in 13 cases, with urinary obstruction in 9 of them.The size of the stones ranged from 0.3 cm × 0.3 cm to stag-horn calculus.The density of the stones measured from a low of 40-70 HU up to a high of 410 HU with an average density of 160 HU.Conclusion CT scan is an excellent modality in demonstrating urinary tract calculi caused by melamine. It is the method of choice when ultrasound examinations are equivocal.
