_________ angina occurs when there is clean coronary arteries that produce ischemia due to vasospasm. Treatment is ______
Prinzmetal’s; CCBs
What additional bone finding is associated with primary hyperparathyroidism?
Osteitis fibrosa cystica (“brown tumor”) — from overstimulated osteoclasts creating large bone lesions
Which of the following commonly cause elevated aminotransferases? Select all that apply
A. Carbamazepine B. Gabapentin C. Isoniazid D. Metformin E. Phenytoin F. Statins
A. Carbamazepine
C. Isoniazid
E. Phenytoin
F. Statins
What do you do if a pt on warfarin has a supratherapeutic INR that is <5 and there is no evidence of bleeding?
Hold a dose
Crescendo decrescendo murmur heard best at aortic region
Aortic stenosis
Symptoms of hypercalcemia
Stones (calcium nephrolithiasis)
Bones (fracture, osteopenia)
Abdominal groans (n/v, pain)
Psychic moans (AMS)
Symptoms of aortic stenosis
Angina (especially on exertion)
Syncope
Active CHF
Management of postrenal failure
The goal is to alleviate the obstruction
Insertion of a catheter can relieve obstruction of the distal GU
Stenting, nephrostomy tubes, and rarely open surgery are used for proximal GU system
Ventricular tachycardia is a wide complex and regular tachycardia. Look for “tombstone” pattern. Since it’s ventricular, there are no p waves at all - just QRS complexes. It responds to __________ (newer/better) or _______ (older/cheaper)
Amiodarone; lidocaine
Management based on kidney stone size
<5 mm = hydration and pain control
<7 mm = medical expulsive therapy (CCBs like amlodipine, alpha blockers like terazosin)
<1.5 cm = ureteroscopy for distal stones, lithotripsy for proximal stones
> 1.5 cm = laparoscopic exploration for proximal stones, percutaneous anterograde nephrolithotomy for distal stones
Initial treatment in the ED for asthma exacerbation
O2
Albuterol/ipratropium nebulizers (to reverse bronchoconstriction)
Corticosteroids (to reverse inflammation)
—Repeat peak flow, CO2 retention, O2 sat, and lung assessment after initial intervention
Pleural effusions are diagnosed on chest x-ray and first become apparent with blunting of the costophrenic angles, which requires at least 250 ccs of fluid. If more than that is present, the air-fluid level rises. In that case, a __________ is needed to assess if the fluid is free moving (not loculated) and in sufficient quantity (greater than ______ from chest wall to fluid level) to do a thoracentesis
Recumbent x-ray; 1 cm
[note that CT scan or bedside ultrasound can also assess for loculation]
Heart rhythm characterized by regularly prolonged PR interval. There’s no interval change between beats but each is prolonged. There are no dropped beats
First degree AV block
2 high intensity statins
Atorvastatin 40, 80
Rosuvastatin 20, 40
Why do patients with DKA often present with hyperkalemia?
- The acidosis drives K+ out of cells into the serum
- Insulin deficiency inhibits K+ transport into cells
Even though they appear hyperkalemic, DKA pts are actually K+ deficient. With the diuresis that results from hyperglycemia, K+ is lost in the urine. When insulin is started and K+ is driven back into cells, serum K+ can drop precipitously. As soon as this happens, K+ needs to be added to the IV fluids and monitored closely during course of tx. If serum K+ is <3.3 mEq/L you must replace that BEFORE starting insulin therapy.
In patients that meet the criteria, screening for lung cancer is done with what test?
Annual low dose CT scan of the chest
What will CXR, EKG, and ABG usually show in the setting of PE?
Normal CXR
EKG shows S1Q3T3 = right heart strain
ABG shows hypoxemic respiratory alkalosis
Pericarditis presents as pleuritic chest pain that improves with leaning forward. It will have a multiphasic friction rub. What is the characteristic finding on ECG?
Diffuse ST elevation with PR segment depression
Causes of obstruction in postrenal failure
Stones and cancer can cause obstruction throughout, but are most often in the ureters
BPH, Neurogenic bladder, and kinked catheters most often affect the distal GU system
Best test for dx of kidney stones
Non-contrast CT
[use US in pregnancy]
Granulomatous disease (sarcoid, TB) can turn on _________ independently of kidneys, which increases calcium and turns off PTH, resulting in phosphate being unable to be renally excreted. Use _______ to treat the underlying disease
Vitamin D
Steroids
Treatment for pericarditis
NSAIDs + Colchicine
Define CVA permissive HTN
> 220 systolic and/or >120 diastolic
Adjustment of risk factors for acute coronary syndrome relating to LDL includes statin therapy with LDL goal of ______ and HDL goal of ______
<70; >40
