NR 511 WEEK 2 STUDY GUIDE, DEFINITIONS AND
ANSWERS
● Identify thhe most common type of pathogen responsible for acute
gastroenteritis.
-Viral: Norovirus (Leading cause for adults)
-Rotovirus (Leading cause for peds up to 2 years old)
● Recognize that assessing for prior antibiotic use is a critical part of
thhe history in patients presenting with diarrhea.
-Order stool studies
● Describe thhe difference between Irritable Bowel Disease (IBS) &
Inflammatory Bowel Disorder (IBD).
-IBS (Irritable bowel syndrome): disorder of bowel function not from
anatomic abnormality
+S/S: result from disordered sensation or abnormal function of
thhe small & large bowel
-IBD (Inflammatory bowel disease): chronic immunologic disease that
manifests in intestinal inflammation
● Discuss two common Inflammatory Bowel Diseases.
-Ulcerative colitis (UC): thhe mucosal surface of thhe colon is inflamed
& ultimately results in friability, erosions, & bleeding.
-Crohns (CD): thhe inflammation extends deeper into thhe intestinal
wall & can involve all or any layer of thhe bowel wall & any portion of
thhe GI tract from thhe mouth to thhe anus.
● Discuss thhe difference between sensorineural & conductive hearing
loss.
- Sensorineural: Results from deterioration of cochlea
-Loss of hair cells form thhe organ of Corti
-Gradual & progressive
-Not correctable but preventable
- Conductive: Obstruction between middle & outer ear
-Most types are reversible
, ● Identify thhe triad of symptoms associated with Meniere's disease.
-Meniere’s Disease: Sensory disorder of labyrinth (semi-circular canal
system) & cochlea
-S/S:
-Vertigo
-Hearing loss
-Tinnitus
● Identify thhe symptoms associated with peritonsilar abcess.
-increasing unilateral ear & throat pain ipsilateral to thhe affected
tonsil
-dysphagia
-drooling
-trismus
-erythhema
-edema of thhe soft palate with fluctuance on palpation
● Identify thhe most common cause of viral pharyngitis.
-adenovirus: MOST common
-RSV
-Influenza A&B
-Epstein-Barr
-coxsackie
-enteroviruses
-herpes simplex
● Identify thhe most common cause of acute nausea & vomiting.
-Gastroenteritis: AGE
● Describe thhe differences between medical billing & medical coding.
-Medical coding: is thhe use of codes to communicate with payers
about which procedures were performed & why.
-Medical billing: is thhe process of submitting & following up on claims
made to a payer in order to receive payment for medical services
rendered by a healthcare provider.
● Compare & contrast thhe two coding classification systems that are
currently used in thhe U.S. healthcare system.
-Thhe CPT system offers thhe official procedural coding rules &
guidelines required when reporting medical services & procedures
performed by physician & non-physician providers.
