1
Q

Definition of diagnosis

A

identification of a disease or condition by a scientific evaluation of physical signs, symptoms, history, lab test results and procedures

2
Q

Types of diagnostics

A
Clinical 
Differential 
Lab 
Nursing
Physical
3
Q

Clinical Diagnosis definition

A

made on the basis of medical history and physical examination without the benefit of lab tests, x-rays and other forms of diagnostic testing

4
Q

Differential Diagnosis definition

A

distinguishing between two or more similar disease with similar symptoms by systematically comparing their signs and symptoms

5
Q

Lab Diagnosis

A

study secretions, excretions or tissue

Conducted through chemical, microscopic or bacterialogic means

6
Q

Nursing Diagnosis

A

Clinical judgement about individual, family or community experiences/responses to actual or potential health problems
Identifies problems that result from a disorder

7
Q

Physical Diagnosis

A

Physical manifestations of health, disease and illness revealed in the physical examination, as guided by the patient’s complete history and supported by various lab tests

8
Q

Clinical Practise definition

A

sound and consistent info gathered from pt

9
Q

Clinical thinking definition

A

info interpreted and put into theoretical/knowledge context

10
Q

pt treatment definition

A

applied on the basis of clinical evidence, guidelines and EBP

11
Q

Reassessment

A

has the treatment worked, is it appropriate, is the pt presenting with a different condition

12
Q

Type 1 error

A

false positive (false alarm)

13
Q

Type II error

A

false negative

14
Q

Sensitivity

A

If a person has a disease, how often will the test be positive.
If the test is highly sensitive and the test result is negative, you can be nearly certain that they don’t have the disease

15
Q

Specificity

A

The ability of the test to correctly identify pts without the disease.
If the test result for a highly specific test is positive you can be nearly certain that they actually have the disease

16
Q

Positive Predictive Value (PPV)

A

How likely is it that the pt has the disease given that the test result is positive?
true positives over true positive + false positives

17
Q

Negative Predictive Value (NPV)

A

How likely is it that the pt has the disease given that the test result is negative?
True negatives over true negatives + false negatives

18
Q

likelihood ratio

A

How much more likely it is that a pt who tests positive has the disease compared with one who tests negative
Sensitivity over 1-specificity
