Dennis Quaid Settles With
Cedars

Cedars-Sinai Medical Center is looking to clear up any bad
blood with Dennis Quaid.
Quaid and his wife Kimberly have accepted a settlement
from the Los Angeles hospital, which last year took
responsibility for giving the babies a life-threatening
overdose of blood thinners.
Zoe Grace and Thomas Boone Quaid, now both 1, were
being treated at Cedars for staph infections in November
2007 when an employee accidentally administered
dosages of heparin (commonly used to flush out I.V.s) that
were 1,000-times the recommended amounts for newborns,
10,000 units per milliliter apiece instead of the standard 10.
Take-Home Lesson:
 On
the exam, you will need to write some
of your answers on the paper exam and
some answers on the scantron.
 If the right answer is on the wrong line, it is
like writing down a patient’s morning
medicine administration on the evening
medication line. The next person will think
the pm dose has already been given and
the patient could die!
Muscle Lab Rules
 NO
open toe shoes!
 Wipe off your counter top with the brown
germicidal disinfectant BEFORE AND AFTER class.
Pour some from the bottle and wipe with paper
towels.
 Frequently spray the cats with preservative in the
spray bottles, especially after class. Place the cat in
a plastic bag, then into the grey bin with the same
number as the label on the cat.
Muscle Lab Rules
 You
almost NEVER need to use a scalpel in lab.
 Almost ALL dissection is done with your fingers and a
probe.
 Make sure you have a good supply of gloves and
BRING THEM each week!
