Maxton, F.J.C., Justin, L. & Gillies, D. (2004). Estimating core temperature in infants and children after cardiac surgery: a comparison of six methods. Journal of Advanced Nursing 45(2): 214-22.

What is the research question? If it is not explicitly written, but is implicit in the article, suggest null and alternative hypotheses.

Which temperature-taking site yields the most accurate readings in babies and young children following cardiac surgery? Temperature is usually measured using the pulmonary artery as a "gold standard." However, the authors hypothesize that because the pulmonary artery cannot be used in the majority of the patients in the target population, other methods can and should be used. In addition to pulmonary artery temperature, the temperatures can be taken at the rectal, bladder, nasopharyngeal, axillary, and tympanic sites.

List the variables used in the study and identify each of them as either independent or dependent variables. Also describe the level...
