Question 2

Gastric Tube (common) (G tube)
Jejunostomy Tube (less common) (J tube)

Answer 2

• long-term feeding

- presence of difficulty swallowing/avoid risk of aspiration.

Question 3

Intravenous System (IV)

Answer 3

• sterile fluid source, a pump, a clamp, and a catheter to insert into a vein.
• superficial veins (basilica, cephalic, or antecubital)

Question 4

Arterial Line

Answer 4

• monitoring device
• measure blood pressure, obtain blood samples.
• if displaced, apply direct pressure and get assistance

Question 5

Central Venous Pressure Catheter

Answer 5

• measures pressures in right atrium/superior vena cava

- evaluates right ventricular function, right atrial filling pressure, and circulating blood volume

Question 6

Indwelling right atrial catheter (hickman)

Answer 6

• inserted through cephalic or internal jugular vein.
• threaded into superior vena cava and R atrium.
• long term administration of substances (ex: chemo, total parenteral nutrition, antibiotics)

Question 7

Intracranial Pressure Monitor

Answer 7

• measures pressure exerted against skull, placed in skull.

- types of monitors (epidural, subarachnoid, intraventricular)

Question 8

Oximeter

Answer 8

• a photoelectric device used to determine oxygen saturation of blood.
• finger/ear
• monitor changes during exercise & position changes.

Question 9

Pulmonary Artery Catheter (Swan-Ganz)

Answer 9

• inserted into pulmonary artery
• soft/flexible
• provides continuous measurements of pulmonary artery pressure
• avoid excessive movement of head, neck, and extremities.

Question 10

Types of Oxygen Therapy (4)

Answer 10

1. Nasal Cannula: up to 6L/min
2. Oronasal Mask:
3. Tent: placed over head/shoulders; higher level of O than normal.
4. tracheostomy mask: placed over tracheostomy/stoma.

Question 11

Arteriography (Diagnostic Test)

Answer 11

• injected radiopaque dye in an artery.

- Shows: Arteriosclerosis, tumors, or blockages.

Question 12

Arthrography (Diagnostic Test)

Answer 12

• invasive test
• contrast medium provides visualization of joint structures through radiographs.
• soft tissue disruption = leakage

Question 13

Bone Scan (Diagnostic Test)

Answer 13

• invasive
• isotopes
• shows stress fractures, infections, and tumors
• can show with as little as 4-7% bone loss

Question 14

Computed Tomography (Diagnostic Test)

Answer 14

• cross sectional images based on x-ray attenuation.

- diagnose spinal lesions and brain

Question 15

Doppler Ultrasonography (Diagnostic Test)

Answer 15

• non-invasive
• ## evaluates blood flow in major veins, arteries, and cerebrovascular system.
