Q

therapuetic Mg concentrations for Pre E? When does it become toxic? What is the first sign

A

5-8
>8= toxic
first sign = delayed reflexes –> HA, lethargy –> respiratory failure –> coma

20
Q

adverse effects of oxytocin

A

Oxytocin is similar to ASH –> as such, infusions can cause HYPONATREMIA –> seizures

can als cause hypotension and tachysystole

21
Q

NAAT comes up positive for chlamydia and negative for gonnorrhea. How do you treat?

A

azithromycin only!

but you treat with both if its gonorrhea +

22
Q

two sample t test for….

chi square for…

A

t test= two means
chi square= categorized outcomes (think of a 2x2 table where even though there are only tw variables, there are 4 combinations)

23
Q

what is the murmur involved with tricuspid valve endocarditis

A

holoSYSTOLIC tricuspid regurg that increases on inspiration

24
Q

“mid diastolic sound”

A

pericardial knock –> ventricles expanding against restrictive pericardium

25
Next step after non reactive non stress test?
BPP or Contraction stress test CI to CST= placenta previa, prior mymectomy
26
most common presentations of CP and greatest risk factor
Presentation: spastic paraplegia in lower extremities with downward pointing toes (equinovarus deformity) Risk: premie <32 weeks
27
prolactinoma vs nonfunctioning adenoma vs antpsychotic med
Antipsychotic will ONLY effect PRL Prloactinoma will have high PRL (ie > 200) Non functioning adenoma likely has CENTRAL hypothyroid (low TSH and T4), low test, high Prl
28
After low uptake RAIU scan, how can you distinguish if this is preformed (thyroiditis) vs exogenous
Thyroglobulin! High thyroglobulin= endogenous
29
elevated alpha subunit:TSH ration suggests?
pituitary adenoma TSH, LH, FSH, bHCG share common alpha subunit
30
whats the parkinsons gate
short, narrow, shuffling
31
congenital hypothyroidism
infants appear normal at birth but then develop: apathy, weakness, large tongue, abdominal movement, umbilical hernia, jaundice SCreen at birth!
32
why labetalol (or esmolol) for acute aortic dissection?
decrease BP and reduce LV contractility (reduces wall stress) (hydral and nitrprusside can cause paradoxical rise in HR/ contractility)
33
t/f: primary hyperPTH can cause htn
true, but unclear way. maybe associated with MEN
34
nephrolithiasis in sarcoid
granulomas produces 1a-OH--> inc vit D --> inc calcium --> inc calcium in urine
35
presentation of CMV retinitis vs HSV/VZV
CMV= painless, does not hvae associated conjunctivitis, fluffy lesions with retinal hemorhages on exam HSV/VZV= rapidly progressive conjunctivitis/kerititis/uveitis . Fundoscopic exam shows pale areas with central retinal necrosis
36
decreased activity/poor feeding in neonate
always have sepsis high!! - can be hyper/hypothermic - can have jaundice
37
care recommendation forplacenta previa
pelvic rest | -no sex, no cervical exams, no vaginal delivery
38
HepC in pregnancy
vax against HepB/HepA (safe) breast feeding is safe
39
avascular necrosis of hip
- pain on weight bearing/ hip abduction/ internal rotation - pain in groin, thigh, butt that's worse with activity - no CXR findings early, no ESR MRI is best test! common in SLE+ long term steroid use
40
HIV prophylaxis in CD4<50
azithromycin for MAC TMP-SMX= - PCP <200 - Toxo <100
41
physiologic tremor is one that...
you can't see at rest, very low freq can acutely onset/worsen with triggers like coffee, anxiety, thyroid
42
two biggest risks for RDS of newborn
maternal diabetes and premie
43
valgus stress=
MCL
44
urge incontinence tx
detrusor over activity --> after bladder training and kegles, use anticholinergic like OXYBUTININ
45
tx for AIHA
high dose steroids
46
SGA most likely to cause prolactin sx and infertility?
risperdal
47
how to treat flash pulm edema in MI
furosemide **do not BB in bradycardia/acute decmpensated heart failure
