Chapter 3 Flashcards
SID for chest projections
72 inches
chest breathing instructions
take exposure after the second full inspiration
chest breathing instructions for unconscious patient
observe the chest moving and take the exposure after the patient takes a deep breath
chest breathing instructions for ventilated patient
observe the ventilator’s pressure manometer to determine when full lung aeration has occurred
chest breathing instructions for ventilated patient with high-frequency ventilator
exposure may be made at any time; this ventilator maintains the lung expansion at a steady mean pressure
pneumothorax or pneumectomy may be indicated if
no lung markings are present
excessive lung markings may suggest conditions such as
fibrosis, interstitial or alveolar edema, or compression of the lung tissue
technical factors if pneumothorax is suspected
decrease kVp 8%
technical factors if pneumectomy is indicated
do not select AEC chamber that is positioned beneath the removed lung or saturation of the opposite lung may present
a patient with suspected pleural effusion should be positioned how
take with patient upright and the x-ray beam horizontal
technical factors if suspected pleural effusion
increase mAs by 35%
what is free intraperitoneal air
air within the abdominal cavity
how must a chest projection be taken if free intraperitoneal air is suspected
take with patient upright and the CR horizontal
desired location of tracheostomy
distal tip is placed 1-2 inches superior to carina
desired location of ETT
distal tip is placed 1-2 inches superior to carina when neck is in neutral position
desired location of pleural drainage tube (chest tube) for fluid
laterally within pleural space at level of the fifth or sixth intercostal space
desired location of pleural drainage tube (chest tube) for air
anteriorly within pleural space at level of midclavicle
desired location of CVC
inserted into subclavian or jugular vein and extends to superior vena cava, about 2.5 cm above right atrial junction
desired location of pulmonary arterial catheter
inserted into subclavian, internal or external jugular, or femoral vein and advanced through right atrium into pulmonary artery
desired location of UAC
inserted into umbilicus and coursed to midthoracic aorta or below level of renal arteries, at about L1-L2
desired location of UVC
inserted into umbilicus and advanced to junction of right atrium and inferior vena cava
desired location of pacemaker
implanted in subcutaneous fat in anterior chest wall and catheter tip(s) directed to right atrium or right ventricle
desired location of automatic ICD
implanted in subcutaneous fat in anterior chest wall and catheter tip(s) directed to right atrium or right ventricle
tracheotomy
a surgical procedure that creates an opening into the trachea to provide an airway
ETT is
a large, stiff plastic, thick-walled tube inserted through the nose or mouth into the trachea
ETT
endotracheal tube
ETT is used to
manage the airway, for mechanical ventilation, and for suctioning
pleural drainage tube is
a 1.25-cm diameter thick-walled tube used to remove fluid or air from the pleural space that could result in atelectasis
atelectasis
collapse of the lung
CVC
central venous catheter
CVC is
a small radiopaque catheter used to allow infusion of substances that are too toxic for peripheral infusion
the pulmonary arterial catheter is also known as
swan-ganz catheter
pulmonary arterial catheter is used to
measure atrial pressures, pulmonary artery pressure, and cardiac output
UAC
umbilical artery catheter
UAC is used to
measure oxygen saturation
UVC
umbilical vein catheter
UVC is used to
deliver fluids and medications
the UAC and UVC are only seen in neonates because
the cord has dried up and fallen off in older infants
pacemaker is used to
regulate the heart rate by supplying electrical stimulation to the heart
care should be taken when lifting the arm of a patient whose pacemaker was inserted within _____ of the examination, because elevation may dislodge the pacemaker and catheter
24 hours
ICD
implantable cardioverter defibrillator
ICD is used to
detect heart arrhythmias and then deliver an electrical shock to the heart to convert it to a normal rhythm
