Multinational validation of anxiety, hopelessness, and ineffective airway clearance.

The effective use of nursing diagnosis internationally depends in part on incorporating language and cultural difference into the common language of nursing. International validation studies can provide a basis for this effort. This study tested three diagnoses--anxiety, hopelessness, and ineffective airway clearance--through multinational validation. The Diagnostic Content Validity (DCV) model was used to collect data from critical care nurses in six countries. Defining characteristics rated as critical (greater than .80) by the total sample were dyspnea for ineffective airway clearance and panic and nervousness for anxiety. No critical defining characteristics for hopelessness were identified. DCV ratios for all defining characteristics are compared by country.

Morphometrics of the skeleton of Dermophis mexicanus (Amphibia: Gymnophiona). Part I. The vertebrae, with comparisons to other species.

Morphometric analysis of vertebral structure in caecilians (Amphibia: Gymnophiona) is presented. Ontogenetic variation in Dermophis mexicanus is analyzed through the 100+ vertebrae composing the column. Vertebral structure in adult D. mexicanus is compared with that in Ichthyophis glutinosus and Typhlonectes compressicauda. Centra of the atlas, second, tenth, 20th, and 50th vertebrae grow at allometrically different rates in D. mexicanus, though the 20th and 50th are not significantly different. Growth appears significantly slower in several dimensions of anterior and posterior vertebrae relative to midtrunk vertebrae in all three species. Mensural patterns throughout the entire column are similar in the terrestrail burrowers D. mexicanus and I. glutinosus; patterns in the aquatic T. compressicauda differ substantially from those of the burrowing species and are strongly influenced by allometry. Of the 112 D. mexicanus examined, 13.4% had vertebral anomalies, usually fusions.
