NURS 752 Exam 3 (Final) Questions with
Guaranteed Pass Solutions Edition.
1. Big 3 Category- Top Misdiagnosis: stroke, sepsis, lung cancer
•
2. #1 cause of malpractice: Misdiagnosis
What helps form hypotheses and create your diagnostic
3.
reasoning?: Epidemiol- ogy
4. Clinical diagnosis requires: info from pt (subjective) 75%
Use that info with ur knowledge of understanding disease + PE is 15%
5.Likelihood Ratios: Weights that help you understand how much a physical sign
argues for or against a diagnosis
Possible weights of 0 to infinity
>1 means increased probability of disease
<1 means decreased probability of disease
6. Specificity: Proportion of patients without the diagnosis who have the physical sign (e.g.
positive finding)
Ex: me for celiac disease
7. Sensitivity: Proportion of patients without the diagnosis who lack the physical sign (i.e.,
, have a negative result)
8.Likelihood Ratio Definition: probability of finding in pts with disease /
probability of same finding in pts without disease
9.2 approaches to clinical decision-making Metacognition
(thinking about thinking): Intuitive vs Analytical
10.Experts vs. Novices: experts gather less data, but better data, organize better =
shorter time to make accurate diagnosis
What makes a good clinical diagnostician? Asking right questions
11.Article: Diagnostic Excellence and Patient Safety - Strategies
and Opportuni- ties: PC- cancer screening (colonoscopy 10 years, FOBT 2 years =
survival rate up)
ED- sepsis (more deaths than some cancers) good improvements but more needed
Inpatient- PE (over tested but under diagnosed) better with clinical decision tools and plasma
dimer measurement
, Article: Big 3 diagnostic errors and serious misdiagnoses
12.
related harms are: · 5 vascular events: stroke, MI, venous thromboembolism, aortic
aneurysm/dissection, arterial thromboembolism
·5 infections: sepsis, meningitis/encephalitis, spinal abscess, pneumonia, endocarditis
·5 cancers- lung, breast, colorectal, prostate, melanoma
Video: Catherine Lucey- Good clinical diagnosticians:: o Eflciently
13.
obtain enough infor- mation from patient to make initial ditterential diagnosis
o Search memory/resources to identify possible causes of patient's symptoms
o Prioritize the likelihood that a possible disease explains patient's concerns
o Use tests (carefully) to evaluate their assessments have to be careful and know and get
correct proper information because some tests are harmful, expensive, wasteful, timely
o Always continue to analyze the success of their diagnoses to improve accuracy going forward
Video: Catherine Lucey- experts:: reorganize their knowledge in a relational
14.
way- S&S to syndromes to disease
15. ACL Article:: common knee injury in athletes
Clinical diagnostic tests and MRI are 2 methods of
evaluating ACL injuries evidence supports clinical diagnostic
tests, faster, sooner, cheaper too gold standard:
diagnostic arthroscopy
, 16. Screening tests: to detect asymptomatic and early stage disease
Should be highly sen/spec to pick up most cases of true disease and avoid
false positives targeted toward pop with higher disease prevalence (high
positive predictive value)
Safe, cost ettective
Should screen for diseases in which early identification and treatment have been demonstrated
to improve clinical outcomes
17. HIV: Grade A- ages 15-65
18. Cervical Cancer: Grade A- ages 21-65
