QUESTION 3

Your hospital unit is divided up into four pods, each containing six patient beds. To keep track of the census of patient volume, the charge nurse collects information each morning on patient diagnoses, length of stay for each patient, acuity level (1-5), and nurses’ reports of likelihood of being discharged (i.e., not at all likely, somewhat likely, likely, very likely, definite). Which of these variables is categorical?

Length of stay

Likelihood of discharge

Patient diagnoses

Age and BMI are quantitative variables

Gender and marital status are categorical variables

Number of sessions is a discrete variable

All of the above

1. Right answer is :All of the above. Age and BMI are continous numbers. Gender and marital status are categorical and no. of session is discrete nos.

2. No of full time facult holding a PHD can't be in fractions. It is discrete / full as always. So, C is right answer - Number of full time faculty holding a PhD

3.likelihood of being discharged takes categorical values - i.e., not at all likely, somewhat likely, likely, very likely, definite.So, C is right
