Mobile radiography is defined as
Radiographic procedures performed at the patients bedside
What are some different situations where bedside radiography might be preferable to imaging in the main department?
Patients in special care units
Orthopedic traction
patient in isolation
What is orthopedic traction?
Mechanical method that uses weights to provide constant pull on the part of the body for therapeutic reasons.
Appropriate procedure for gathering info before bedside x-ray.
Call nurse ask about cond.

Three reasons why X-rays are ordered for patients in PACU?
1) Check line placement
2) Rule out pneumothorax or atelectasis
3) Check orthopedic hardware placement

Special unit for care ob babies who are premature, low birth weight, or have a health issue
neonatal intensive care unit (NICU)
Why are mobile exams often performed while an infant is in an incubator?

The right of left pulmonary artery
An implanted device that electrically stimulates the heart to control its rate is called a:
Pacemaker
A Swanz-Ganz is what type of catheter?
Pulmonary artery flow-directed catheter that measure cardiac output.
If a patient has recently had a pacemaker put in what resctricions are placed on the patient for 24 hours after surgery to prevent dislodging it.

Yes

"Fluoro-capable" (radiolucent)
What is the PACU?
post anesthesia care unit
Designed and staffed to closely observe and care for patients after operative procedures that require anesthesia
Common complaint of patients in the PACU
being cold
This is because of the anesthesia, premedication and the cool atmosphere of the operating suite and PACU
altered state of consciousness
a type of consciousness other than normal waking consciousness
Confused, drowsy, or comatose
What kind of pediatric health problems might require radiographs
Pediatric respiratory distress syndrome (PRDS)
Newborn atelectasis (failure of the lungs to expand completely)
What are neonates at risk placed in?
An incubator under a radiant warmer or an enclosed incubator
Enclosed incubators
provide a closed environment with extra warmth, moisture and oxygen while reducing exposure to airborne infection
Should you open a closed incubator or handle a newborn unless a nurse of physician is present?
No
T or F: The neonate at risk must remain within the enclosed incubator for radiographs,
True
Why might some patients need to lie on an alcohol or water filled pad?

tracheotomy
The opening through which a tube may be placed is called
A tracheostomy
Where are patients with a new tracheostomy monitored?
The ICU
Why are the tapes that hold the tracheostomy tube never untied?
Because a sudden cough can expel the tube, and the edges of the tracheostomy may close sufficiently to obstruct respiration
What are nasogastric (NG) or nasoenteric/nasoenteral (NE) tubes?
Tubes passed through the nose and down into the stomach or small intestine
Purposes of NG tubes

remove air
Tubes placed through the posterior inferior chest wall......
drain fluid that collects at the base of the pleural space
Where must the chest drainage unit remain?
below the level of the patients chest to avoid reverse flow from the unit
A central line may be referred to as a
central venous catheter (CVC)
What is a PICC?
peripherally inserted central catheter
Pulmonary artery flow directed catheters
measure cardiac output, the pressures on the right side of the heart and indirectly the left heart and lung pressures
Pulmonary artery flow directed catheters diagnose
right and left ventricular failure and monitor the effects of specific medications, stress, and exercise on heart function
CVC facilitate
the administration of chemotherapy or another long term drug therapy, total Parenteral nutrition, dialysis, or blood transfusions
Central venous catheters (CVC) can be classified as:
Short or long term nontunneled external catheters
Long term tunneled external catheters
Long term implanted infusion ports
Where are short or long term nontunneled external catheters usually delivered and where do they go?
They're usually inserted at the bedside
They are placed through the skin and directly into a vein in the neck, shoulder, groin, or antecubital fossa
Where is the PICCA inserted?
Into a vein in the patients arm, at or superior to the antecubital fossa, and advanced until it's tip lies in the superior vena cava
Long term implanted infusion ports are used for
Patients who need intermittent infusion of medication or chemo. Blood transfusions, or the sampling of blood from the superior vena cava
The port, enclosed in plastic or metal, and an attached venous catheter are surgically implanted and sutured under the skin of the upper chest or arm
The artificial pacemaker is
an electromechanical device that regulates the heart rate by providing low levels of electrical stimulation to the heart muscle to replace the stimulation that is normally provided by nerve impulses
The pacemaker consists of
a battery powered energy source and a wire or catheter delivering electrical stimulation to the heart
Internal pacemakers are
surgically implanted inside the patients chest
External pacemakers
Are usually temporary, and the bulk of the instrument remains outside the chest in a "pocket" under the skin
Restriction placed on patients following the insertion of a pacemaker
Patient should avoid abducting or elevating the left arm for 24 hours after surgery to prevent dislodging the pacemaker and catheter
