chapter 11 patient preparation Flashcards
CT history forms seek to
- patient safety
- correct selection of protocol
- providing information useful for interpreting the examination
questions on medical history regarding ____,_____and ____ help determine id patient will revive IV contrast
- renal function
- allergies
- thyroid conditions
lab values most frequently reviewed before CT exam
blood urea nitrogen (BUN)
serum creatinine
normal range for BUN
7 and 25 milligrams per deciliter
normal range for serum creatinine
0.6 to 1.7 mg/dl
If the BUN is higher then ___IV contrast cannnot be given
30mg/dl
If the serum creatinine is higher then ___IV contrast cannnot be given
2 mg/dl
the lb vales for BUN and creatine provide information about
patient renal function
the labs values for PT and PTT provide information about
blood’s coagulation ability
prothrombin (PT) range is
11 to 14 seconds
partial thromboplastin time (PTT) range is
25 to 35 seconds
platelet count range is
150,000 to 400,000 cubic millimeter mm3
common anticoagulant medications
warfin(coumadin) ,heparin,plavix, and aspirin
when the tech has not provided consent for an exam the tech who preforms the exam may be liable for

-treatment is given under the understanding that if the patient were able to give
consent they would want treatment.
Informed consent
usually get a written response
the best early indicator of physiologic change in a patient is
vital signs
vital signs are
- body temperature
- pulse
- respirations
- blood pressure
pulse
the alternate expansion and recoil of an artery
the average adult pulse rate range from
60 to 100 beats per min
pulse for athletic adults
45 to 60 beats per min
pulse for children
95 to 110 beats per min
pulse for infants
100 to 160 beats per min
respiratory rate
the number of breaths a person takes per min
blood pressure
the pressure exerted by circulating on the walls of the vessels
systolic pressure
the peak pressure in the arteries : which occurs near the beginning of the cycle
diastolic pressure
is the lowest pressure (at the resting phase of the cardiac cycle
hypertension
refers to blood pressure that is abnormally high
hypotension
refer to blood pressure that is abnormally low
a healthy blood pressure is
120/80 mmhg
