Q

desired location of pleural drainage tube (chest tube) for air

A

anteriorly within pleural space at level of midclavicle

18
Q

desired location of CVC

A

inserted into subclavian or jugular vein and extends to superior vena cava, about 2.5 cm above right atrial junction

19
Q

desired location of pulmonary arterial catheter

A

inserted into subclavian, internal or external jugular, or femoral vein and advanced through right atrium into pulmonary artery

20
Q

desired location of UAC

A

inserted into umbilicus and coursed to midthoracic aorta or below level of renal arteries, at about L1-L2

21
Q

desired location of UVC

A

inserted into umbilicus and advanced to junction of right atrium and inferior vena cava

22
Q

desired location of pacemaker

A

implanted in subcutaneous fat in anterior chest wall and catheter tip(s) directed to right atrium or right ventricle

23
Q

desired location of automatic ICD

A

implanted in subcutaneous fat in anterior chest wall and catheter tip(s) directed to right atrium or right ventricle

24
Q

tracheotomy

A

a surgical procedure that creates an opening into the trachea to provide an airway

25
Q

ETT is

A

a large, stiff plastic, thick-walled tube inserted through the nose or mouth into the trachea

26
Q

ETT

A

endotracheal tube

27
Q

ETT is used to

A

manage the airway, for mechanical ventilation, and for suctioning

28
Q

pleural drainage tube is

A

a 1.25-cm diameter thick-walled tube used to remove fluid or air from the pleural space that could result in atelectasis

29
Q

atelectasis

A

collapse of the lung

30
Q

CVC

A

central venous catheter

31
Q

CVC is

A

a small radiopaque catheter used to allow infusion of substances that are too toxic for peripheral infusion

32
Q

the pulmonary arterial catheter is also known as

A

swan-ganz catheter

33
Q

pulmonary arterial catheter is used to

A

measure atrial pressures, pulmonary artery pressure, and cardiac output

34
Q

UAC

A

umbilical artery catheter

35
Q

UAC is used to

A

measure oxygen saturation

36
Q

UVC

A

umbilical vein catheter

37
Q

UVC is used to

A

deliver fluids and medications

38
Q

the UAC and UVC are only seen in neonates because

A

the cord has dried up and fallen off in older infants

39
Q

pacemaker is used to

A

regulate the heart rate by supplying electrical stimulation to the heart

40
Q

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

A

24 hours

41
Q

ICD

A

implantable cardioverter defibrillator

42
Q

ICD is used to

A

detect heart arrhythmias and then deliver an electrical shock to the heart to convert it to a normal rhythm
