irritation and insomnia. Which of the following should the respiratory
therapist first recommend? Answer: frequently rotate the site and
discontinue at night

everything went black. Which of the following is a likely cause?
Answer: the light source is disconnected
⩥ A patients blood pressure monitored through an arterial catheter is
126/78 mm Hg. The transducer is mounted on a free-standing IV pole.
The bed is lowered to permit routine patient care. How will this affect
the measured blood pressure Answer: decrease systolic, decrease
diastolic
