65

Patient develops dyspnea 2 days after beginning course of antibiotics for pyelonephritis. What is the diagnosis and why?

Acute respiratory distress syndrome (ARDS) --> 1-2 days after Abx are given, if the organism is gram NEGATIVE, the lysis of the bacteria release the endotoxins --> these endotoxins cause pulmonary injury, leading to capillary leakage of fluid into pulmonary interstitial space ("capillary leakage")

66

What CMP component will be increased w/ a GI bleed and why?

BUN --> digested blood in the GI tract is a source of urea

67

69

Highest risk for diabetic foot ulcers?

Diabetic Peripheral Neuropathy

MOA: multifactorial and is thought to result from vascular disease occluding the vasa nervorum; endothelial dysfunction; deficiency of myoinositol-altering myelin synthesis and diminishing sodium-potassium adenine triphosphatase (ATPase) activity; chronic hyperosmolarity, causing edema of nerve trunks; and effects of increased sorbitol and fructose. Other etiologies of diabetic ulceration include arterial disease, pressure, and foot deformity.

89

Why do you get alkalosis w/ taking loop diuretics?

Loops cause excretion of Na (& H2O), K, and Cl in the urine and lower the blood levels --> decreased K+ levels cause the K/H cellular pumps to transport H+ INTO cells and K+ OUT of cells to normalize blood K levels --> the drop in blood H+ levels causes alkalosis

90

122

Why does serum Na drop during prolonged vomiting or diarrhea?

GI tract fluids have Na concentration similar to plasma; as these fluids are lost (vomiting or diarrhea), the Na levels will drop due to lack of absorption from GI tract --> these fluids should be replaced w/ isotonic, Na-containing fluids. However, most people drink water (hypotonic) --> the body retains this water b/c of its volume depletion --> results in dilutional hyponatremia

Dilutional hyponatremia --> when isotonic fluids are lost (vomiting/diarrhea) and replaced by hypotonic (water) fluids.

147

What is overflow/stress incontinence?

What is best initial treatment?

Why not 5a-reductase (-)?

Large prostate causes outlet obstruction and traps a large amount of urine in the bladder. The involuntary urine loss (during cough, sneeze) occurs when bladder pressure > urethral pressure.

Tx: alpha-blocker (doxazosin, terazosin, tamsulosin) --> these RELAX the sphincter, allowing easier voiding

5a-reductase (-) --> takes a LONG TIME to act (up to FULL YEAR) so not appropriate for immediate relief

148

What is urge incontinence?

2nd: 5a-recductase (-) (finasteride) --> blocks conversion of testosterone to dihydrotestosterone in the prostate --> DHT responsible for hormone-dependent enlargement of the prostate

170

Does Hgb or Hct change during acute blood loss?

NO --> Hct or RBC count only decreases as fluid from other body sources (ECF) enters intravascular space in response to a decreased intracapillary blood pressure. This takes about 4-6 hours for normalization to occur

If IV fluids are given, this causes a dilutional effect and Hct may decrease

How to distinguish R ventricular infarct vs cardiac tamponade?

Pulsus paradoxus

Tamponade: both ventricles already compressed -> during inspiration, venous return increases to R ventricle --> excess filling and expansion of R ventricle that further compresses and displaces the L ventricle --> LV ejection fraction and contraction very low and causes low systolic BP during inspiration

R vent infarct: heart not being compressed and any increase in RV volume is accommodated by pericardial sac
