150-500
vs
^1000
and what is initial goal of therapy when triglycerides ^1000
150-500 - lifestyle Weight Loss, Alcohol decrease, Exercise increase, High Dose Statin IF CAD or High Risk
^1000 (initial goal Prevent Pancreatitis)
-Fibrates, Fish Oil, Abstain from Alcohol
166
triglycerides 465 in CAD patient -- what to do other than start high dose statin?
150-500 - lifestyle Weight Loss, Alcohol decrease, Exercise increase, High Dose Statin IF CAD or High Risk
^1000 (initial goal Prevent Pancreatitis)
-Fibrates, Fish Oil, Abstain from Alcohol
167
most effective pharmacologic therapy for lowering triglyceride levels
when to use it
Fibrates most effective for lowering triglycerides
use for SEVERE Hypertriglyceridemia ^1000 -- otherwise risky for myopathy and statins more effective by evidence so statins first-line for most CAD and moderate triglyceridemia

75yo DM and HTN, with cupping of optic disk on exam, loss of peripheral / tunneling of vision, why?
treat
OPEN Angle Glaucoma - cupping of optic disk
BB (Timolol) eye drops initial mgmt
Laser Trabeculoplasty as adjunct
Trabeculotomy if refractory
169
presentation of open vs closed angle glaucoma
Open - gradual loss of peripheral vision / tunneling, cupping of optic disk
Closed - Sudden onset Blurred Vision, Severe eye Pain, Nausea, Vomiting, Red eye with Hazy Cornea and Fixed Dilated Pupil
170
20yo with atypical chest pain and short systolic murmur at the apex that shortens with squatting... diagnosis?
MVP mirtal valve prolapse
squat, increase venous return... larger LV volume, delayed prolapse? per UWorld... thinking.... better stretched... less distance to prolapse....
MVP gets SOFTER with squat
MR gets LOUDER with squat
171
which gets louder with squatting and which gets softer MR vs MVP
MR gets LOUDER with squat
(more LV volume to regurge)
MVP gets SOFTER with squat
(more LV stretch, tighter chordae... less distance to flick back)
172
1st and 2nd most common Murmurs caused by Rheumatic Heart Disease
RHD
MS Mitral Stenosis #1
MR Mitral Regurge way less often

4 risk settings for ARDS
vent settings to treat with
how to avoid mortality
infection
trauma
massive transfusion
acute pancreatitis
treat with Mechanical Ventilation
-LOW TV, high PEEP, Permissive HyperCapnia
AVOID alveolar OVERDISTENSION (barotrauma) (low TV)
GOAL SpO2 ^88%
175
Pt put on vent for ARDS
what is the MOST important treatment strategy to avoid mortality?
Avoid Alveolar OverDistension (barotrauma) (low TV)
| GOAL SpO2 ^88%
176
most common causes of Malignant pleural effusions
lung carcinoma
breast carcinoma
lymphoma
177
top 4 ddx for hypokalemia with alkalosis and normotension
how does urine chloride help you differentiate
surreptitious vomiting - low urine chloride
diuretic abuse
Bartter syndrome (renal protein mutation)
Gitelman's syndrome (renal protein mutation)
(all high urine chloride)
178
what kind of acid/base disturbance in chronic diarreha
metabolic ACIDOSIS
| from loss of bicarb in stool
179
How can COPD exacerbation lead to seizure
and how can over-supplementation of oxygen contribute? Guidelines for use?
Seizure by HYPERCAPNIA (causes brain metabolite signaling changes) and reflex cerebral VasoDILATION
use Oxygen Cautiously with Goal SpO2 90-93% or PaO2 60-70mmHg
Too Much can Worsen HyperCapnia by:
- Loss of Hypoxic pulmonary Vasoconstriction and worsening V/Q mismatch.. increased deadspace perfusion
- Decreased CO2 reuptake because more O2 saturation
- Suppressed Hypoxic Respiratory Drive
180
Goal SpO2 and PaO2 in oxygen supplementation for COPD exacerbation
In COPD exacerbation, use Oxygen Cautiously
with Goal SpO2 90-93% or PaO2 60-70mmHg
Too Much can Worsen HyperCapnia by:
- Loss of Hypoxic pulmonary Vasoconstriction and worsening V/Q mismatch.. increased deadspace perfusion
- Decreased CO2 reuptake because more O2 saturation
- Suppressed Hypoxic Respiratory Drive
181
how can Zollinger-Ellison syndrome cause impaired fat absorption?
Gastrin producin tumor
high Acid
Impaired Pancreatic Enzyme Activation by duodenal base and Injury to the Mucosal Brush Border
182
workup of Zollinger-Ellison Syndrome
Gastrin level ^1000
Gastric pH v4
Endoscopy for ulcers (duodenal and maybe jejunal)
CT MRI SomatoStatin Receptor Scintigraphy to ID Pancreatic tumors (tumor often located in pancreas) and Mets
once confirmed, screen for MEN1 with PTH, Ca, PRL levels
