Practice questions
- What was the central hypothesis tested in the rabbit thoracic arthrodesis study?
- Which animals were included in the study?
- How were the rabbits allocated between the intervention and comparison groups?
- Which procedure defined the experimental intervention?
- What was the role of the sham-operated group in this experiment?
- At what postoperative time point were echocardiographic images obtained?
- Which echocardiographic methods were used to assess the rabbits?
- When and from where were blood samples obtained for blood-gas analysis?
- Which statement correctly describes the timing and setting of thoracic CT?
- Which set lists the thoracic measurements reported from CT?
- A rabbit has a chest depth of 4 cm and chest width of 8 cm. Using the study's definition, what is its thoracic index?
- Which combination of morphometric outcomes was reported as lower in operated rabbits than in sham-operated rabbits?
- Which conclusion best reflects the reported cardiopulmonary findings in the operated rabbits?
- What is the most appropriate interpretation of a lower thoracic index in an operated rabbit?
- The study states that echocardiographic variables were higher than values reported in anesthetized rabbits. Which comparison does this describe?
- In what sequence were blood-gas sampling, echocardiography, CT, and euthanasia performed?
- What was done with the heart and lungs after the animals were euthanized?
- Which conclusion would exceed the evidence from this study?
- Which statement best captures the distinction between the study's structural and functional endpoints?
- A reader claims that the study proved all cardiopulmonary outcomes were equivalent between operated and sham-operated rabbits. Which response is most accurate?
- Which option correctly describes the thoracic index used in the study?
- Which feature of the study most directly supports comparing thoracic measurements after arthrodesis with measurements after a procedure-control condition?
- Which statement about the study's follow-up and developmental context is accurate?
- An investigator wants to cite this experiment as evidence that an altered thoracic cage necessarily impairs cardiac function. Which assessment is most defensible?
- Which outcome was assessed by blood-gas analysis rather than by CT morphometry?
- Which conclusion is justified by the reported thoracic morphometry?
