NSG 6420_QUIZ 2 REVIEW NOTES
CAD major risk factors
HTN, smoking, obesity, physical inactivity, dyslipidemia, diabetes, Microalbuminuria, GFR <60, age (>55men, >65 women), Fam hx of premature cardiac dx
Etiology of AS
Congenital and senile calcifications
AR etiologies
HTN, aortic dissection, syphilis, collagen vascular disorders
MR etiologies
rupture chordae tendinae, CAD, MVP, infectious endocarditis
AS characteristics
*increased with pt leaning forward
*crescendo-decrescendo/diamond shaped murmur
*radiates to neck
*Early systolic "click"
Most common cause of AS?
calcification of a normal trileaflet or congenital bicuspid valve
MR characteristics Radiates to chest and axilla
*high pitch with blowing quality
*pansystolic regurg murmur with thrill
Standing will decrease murmur, squeezing both hands will increase murmur
MR complications
afib - affects approx 75% with MR systolic embolization
bacterial endocarditis
Most common cause of MR? MVP
Prophy antibiotics?
invasive procedures and dental cleaning if MR and MVP
CHF s/sx
Cough at first nonproductive at night, progressing to frequent cough productive of pink frothy sputum
orthopnea
What is diabetes equitable to? Heart disease
-assumed the patient with DM already has microvascular dx processes in place
HDL, Triglyceride levels
>40 in males, >50 in females
Trigs <150
Secondary hyperlipidemia causes? identifiable diseases or conditions:
DM, metabolic syndrome- reversible with control or eradication
Primary hyperlipidemia causes?
Hereditary or sporadic genetic disorder of lipoprotein metabolism
Not modifiable hyperlipidemia causes?
genetic predisposition, fam hx of atherosclerotic dx, male sex, and age (men >45, women>55)
LDL goal for highest risk patients Known CVD, DM, CVA, PVD, AAA
70
Gold standard test for PAD and values ABI
1.0-1.4 normal
0.9-1.0 acceptable
0.8-0.9 some dx
0.5 and less; refer Greater than 1.4 refer
Dx of diabetes? A1c >/6.5%
FPG >/126 (at least 8 hours NPO) 2 hour PP glucose >/ 200
Random plasma glucose >/200 with classic symptoms
DM cholesterol guidelines LDL <100
HDL men >40 women>50 TG <150
MOA of Biguanides METFORMIN (glocophage)
-reduces glucose production by liver
-enhances insulin sensitivity at tissues MOA of alpha glucosidase inhibitors
PRECOSE
-slows down absorption of carbs in small intestine
MOA of Thiazolidinediones Pioglitazone (ACTOS)
-Improves insulin sensitivity, transport and utilization at target issues
DPP4 inhibitor MOA JANUVIA, JANUMET
enzyme that destroys hormone incretin
*Meds block that action
Sx and labs of DKA
Hyperglycemia, ketosis, acidosis, dehydration
-lethargy/weakness, dehydration (dry MM, tachy, orthostatic hypotension), abd pain (N/V), Kussmaul respirations
Labs: BG >300, PH <7.3, bicarb < 15, ketones in blood and urine
HHS sx and labs BG >400
absent/minimal ketone bodies Fewer sx in earlier stages
h/o inadequate fluid intake, increasing mental depression, polyuria
PUD causes and risk factors
causes: H.pylori, NSAIDs, ETOH, steroids
Risk factors: ETOH, smoking, male, >40, fam hx
Duodenal ulcer causes
h.pylori associated with 95% of duodenal ulcers
Hep C diagnosis
Neg anti hcv eia and hcv rna= not infected
+EIA and - RNA=resolved infection
-EIA and +RNA=early acute infection or chronic infection in immune compromised person
++= acute or chronic infection
What indicates a dx of pancreatitis? elevated amylase and lipase
What is elevated in acute cholecystitis? alkaline phosphatase and bili
High WBC
acute appendicitis pain
begin in periumbilical and then localize to rt lower quad
Perforated duodenal ulcer pain
epigastrium initially, then migrates to the lower quadrants
Biguanides MOA Metformin (Glucophage)
-Decreases amount of glucose released from liver
Sulfonylureas MOA
Glimepiride, Glyburide, Glipizide
-Stimulated pancreas to release more insulin, right after a meal and then over several hours
Thiazolidinediones MOA Actos
-makes the body more sensitive to the effects of insulin
-Keeps the liver from overproducing glucose
DPP-4 inhibitors MOA Januvia
-Improves insulin level after a meal and lowers amount of glucose made by your body
Meglitinides MOA Prandin, Starlix
-non-sulfonylurea
-resembles sulfonylureas in MOA
