[R] Right tailed test. BETTER = Rt. tail(better)

What is a Right Tailed Test?

A right tailed test (sometimes called an upper test) is where your hypothesis statement contains a greater than (>) symbol. In other words, the inequality points to the right. For example, you might be comparing the life of batteries before and after a manufacturing change. If you want to know if the battery life is greater than the original (let’s say 90 hours), your hypothesis statements might be:
Null hypothesis: No change (H0 = 90).
Alternate hypothesis: Battery life has increased (H1) > 90.
The important factor here is that the alternate hypothesis(H1) determines if you have a right tailed test, not the null hypothesis.

[CK] Stress-dose gluticocorticoid(steroid) [v ] read and sum! (50mcg IVP solucortef vs 125mg solumedrol=for steroid user>5mg pred.)

STRESS DOSE Solucortef 50mg q6hr ! or Solumedrol 60-125mg iv q6-8hr !(severe sepsis shock or known prednisone user !) https://www.uptodate.com/contents/glucocorticoid-therapy-in-septic-shock?topicRef=1613&source=see_link Summary ● Random <10 but don't rely on lab test. => just do it if it's indicated in critically ill patient.s  ● "functional" adrenal insufficiency, "relative" adrenal insufficiency,  "critical illness-related corticosteroid insufficiency (CIRCI)."  =But a clear definition is lacking ● Less severe septic shock: restored by fluid and pressor = corticosteroid therapy does not appear to be beneficial. ● Severe septic shock: sBP <90 with adequate fluid + vasopressor (more than 1 hr, NE >0.5) .=> may need to add 2nd dose or...  = reduces weaning pressor quicker. => start within 24hours for severe septic shock.   ●   ACTH stimulation testing is not clinically useful.
