possible tests today

**UPDATE TO THIS POST**  i am so grateful that God saw it fit to answer my prayer today about these tests.  ken's lung function was well enough to perform a CT scan, and that went well enough that they were able to do the lumbar puncture just a bit ago.  thank you thank you for praying.  i prayed specifically that God would be a shield around kenny, so i want to acknowledge His goodness for experiencing that tonight. 
 
today the doctors have changed the ventilator settings on ken - not necessarily for better or worse, just a different mode - to see if he could tolerate a lumbar puncture (a procedure done to better understand the source of his fevers).

they would also like him to undergo a CT scan for most of his body (also to gain more knowledge about why the fevers may be happening.)

right now, we are waiting for bloodwork to come back to determine how well he's tolerated the new ventilator settings which will help the trauma doctors make their decision about the lumbar puncture procedure.

i am praying for God to speak clearly and powerfully to the doctors who are making this decision for ken.  i look forward to getting some necessary answers from these tests, but of course only if his body (mainly lungs) can tolerate it beautifully.  whatever the doctors choose for ken, i want it to be God's decision for his son - whatever God sees best for him.  i would so appreciate your prayers with this.  thank you

from the message, lamentations 3

i'll never forget the taste of trouble, the utter lostness,
the taste of ashes, the utter poison i've swallowed.
i remember it all - oh, how well i remember
the feeling of hitting the bottom.
but there's one thing i remember,
and remembering, i keep a grip on hope:

god's loyal love couldn't have run out,
his merciful love couldn't have dried up.
they're created new every morning.
how great is your faithfulness!
i'm sticking with god (i say it over and over)
he's all i've got left.

god proves to be good to the man who patiently waits
to the woman who diligently seeks.
it's a good thing to quietly hope,
quietly hope for help from god.
it's a good thing when you're young
to stick it out through the hard times.

when life is heavy and hard to take,
go off by yourself.  enter the silence.
bow in prayer.  don't ask questions:
wait for hope to appear.
don't run from trouble.  take it full-face.
the "worst" in never the worst.

why? because the Master won't ever walk out
and fail to return.
if he works so severely, he also works tenderly.
his stockpiles of loyal love are immense.
he takes no pleasure in making life hard,
in throwing roadblocks in the way.
