56 is the difference between the systolic and diastolic pressure and is called the pulse pressure, which is an indicator of the tone of the arterial blood vessel walls. 212 is not the pulse pressure. 134 is the systolic pressure. 78 is the diastolic pressure.

A researcher who has just submitted a trimmed-down version of her doctoral dissertation to a journal editor receives the following. What type of letter is it? (Select all that apply.) Dear Ms. Smith:
We have received your manuscript and are returning it to you. Our journal's focus is exclusively quantitative research, and your manuscript uses a mixed methodology. Despite notable strengths of the quantitative portion, which contains cutting-edge information about medication errors and their correlates, our peer reviewers feel that you might be better served in seeking a venue that allowed both aspects of the study to be presented. The Nursing Journal of Mixed Methodologies springs to mind. Nonetheless, if you should wish to resubmit only the quantitative portion, essentially as it stands, we should be quite interested in returning it to the peer reviewers. Please see the one accompanying suggestion for table insertion. a. An outright rejection b. An acceptance c. An acceptance with minor revisions d. A rejection of the manuscript as currently written e. A suggestion for an alternative avenue of publication f. A compliment
