46
Q

what is a food frequency questionnaire

A

you ask the client to identify a number of times per day, week, month a particular food group is eaten
provides a broadened view of the patients nutritional intake
accuracy is a problem because it relies on recall

47
Q

what is a food record

a patient keeps a record of measured/weighed amounts of food over a 3-day period
allows the nurse to get the total Kcal and nutrient content
it is the most accurate

48
Q

what is a full liquid diet

A

contains all the liquids in the clear liquid dietplus any food that are liquid at room temperature

49

53
Q

what is basal metabolic rate? (BMR)
