In these cases asking patients about their symptoms is important, and the nurses must know what to ask for. This leads to both the problem and purpose of this study, where the nurses' perceptions about their abilities to assess and advise these patients are not known and hence need to be studied. This is a suffieciently narrow yet sigbificant problem in palliative care nursing where the disease needing palliative care has many problems per se, and depression is a common occurrence as an association that may be neglected easily. The population is thus about to die due to any cause where treatment fails, settiing become palliative care, and the variables become the nurses' perceptions about their knowledge and confidence about depression in these patients, and depressive symptoms. This also clarifoes the aim of the study which is to gather information about these variables. As evident, this problem is relevant to nursing care, since if they are proved to be having string perceptions about the depression and its effect on these patients, they can engage these patients into discussion about their depression, and that can be additional responsibility of these nurses while delivering palliative care. This study was very feasible in terms of money commitment and with certainty of availability of subjects in the palliatice care settings. This would not add to the extra cost since existing facilities and services would be used, and no extra equipment would be necessary. Ethically this was a sound hypothesis, and there are no reasons for it to be not ethically cleared by the appropriate authority. The authors are qualified and they are, although not categorically mentioned it seems, professors of university nursing schools.
