Q
10 communication barriers for situation awareness
A
- Hierarchy: the more people the message has to flow through, the more likely the message will get distorted
- Unexpected messages: if the message stuns the receiver, the brain can get bogged down and prevents new messages from being processed
- Multiple incoming cues: we can’t multitask listening, instead we interleave = single tasking in multiple succession
- Emotions: when something triggers a emotional memory you may zone out and miss some components of the current message
- Physical distance: the greater the distance between the sender and the receiver, the greater potential for miscommunications
- Conflicting messages: when a receiver hears 2 messages that are in conflict they have to device which one to believe, can be wrong
- Relationships: humans can favour messages communicated by people they have good relationships with
- Expected messages: when the message is expected, the receiver can tune out the message and the messenger
- Volume of information: the receiver can suffer from info overload, they then filter info and can filter out important points
- Source of information: we evaluate the trustworthiness of the sender and base whether we believe the info on whether we trust them

3. Partial (focal)
145
A change in the glascow scale score could be caused by what?
Intracranial pressure
146
Common characteristics of CVCs?
- rigid material for placement that also lowers the incidence of blood clots
- radiopaque strips at the distal end to allow verification of placement
- single or double lumen
- distal tips rest in vena cava near right atrium of heart
147
3 different categories of "getting information"
1. The nature of the information: patient, environment, task, time, static vs. dynamic
2. Info Delivery: active vs. passive
3. Source of information
4. Collecting info
148
Characteristics of a PAC?
- can be quadruple lumen depending on purpose
- often seen in ICU or CCU patients who require intensive monitoring
- considered a CVC or central line
149
What does a healthy blood vessel feel like compared to a normal one?
Healthy: soft
Unhealthy: hard
150
Classification of CVCs?
1. Short or long term, non tunneled external catheters (PICC)
2. Long term, tunneled external catheters (Hickman, Groshong, Raaf)
3. Long term, implanted infusion ports (Port-a-cath)
151
What is the most important rule when it comes to crash carts?
Never borrow anything from a crash cart
152
What is anaphylactic shock? Most common causes?
Result of an exaggerated hypersensitivity reaction, releasing histamine and bradykinin in the body = widespread vasodilation and peripheral pooling of blood
- most common causes: meds, iodinated contrast, insect venoms
- signs/symptoms depend on severity
- more abrupt onset = more severe
- contraction of nonvascular muscles (respiratory tract)
153
Chest tube location
For air: anterior and superior
| For fluid: posterior and inferior
154
What is usually the first sign of respiratory distress?
Sudden onset of shallow, rapid breathing
155
Radiographer's response to nausea and vomiting
1. Support the patient by sitting them up or placing in lateral recumbent, airway clear
2. Reassure the patient by talking to them
3. Don't rush their recovery
4. Provide simple breathing instructions
5. Provide emesis basin and replace often with a clean one, give moist wash cloth to patient
156
Why do we take a radiograph after tube insertion?
To ensure it has been correctly placed and did not go into the lungs
157
Why do we "tunnel" the catheters?
Tunneling under the skin helps hold the catheter in place and prevent infection
158
What are electrodes?
Electrical contacts that can receive electric signals produced by the patient's heart
159
Mild to moderate contrast reaction signs/symptoms?
- itchy skin
- development of urticaria (hives) or skin rash
- nasal congestion, sneezing, watery eyes
- coughing with possible laryngeal swelling
- peripheral tingling
- tachycardia (>100BPM) or bradycardia (<60BPM)
- hypotension
- feeling of fullness or tightness in chest, mouth, or throat
- feeling of anxiety or nervousness
160
What are the four ways to gather information you need
1. Scan and search
2. Pay attention
3. Remain watchful
4. Communicate
161
3 main functions of a NE tube?
1. Decompression
2. Radiographic exams
3. Feeding
162
What is a weak pulse a sign of?
- problems with the heart's ability to pump as much blood as the body needs
- shock
- circulation problems (partially blocked, narrowed vessel)
163
Why do we "tunnel" the catheters?
Tunneling under the skin helps hold the catheter in place and prevent infection
164
Indications for chest tube insertion?
- hemothorax: blood in the pleural cavity
| - pneumothorax: air in the pleural cavity
165
Physical evaluation includes assessing what?
- Skin colour
- Skin temperature
- Breathing
- Level of consciousness
166
What medical procedure can cause and pneumo/hemothorax?
Thoracotomy: performed to diagnose or treat disease or injury to the lungs or pleura
167
When you are getting information, what things should you consider?
- The nature of the information: PETT, is it static or continuously dynamic
- Information delivery: are you collecting it passively or actively, don't rely on passive info-ask questions
- Information source: people, tools, devices, and documents
- Collecting information: scan and search, pay attention, remain watchful, communicate
168
Why do we take a radiograph after tube insertion?
To ensure it has been correctly placed and did not go into the lungs
169
Recognizing shock
- sense of apprehension
- may be restless
- change in ability to think
- change in skin appearance/colour
- pallor accompanied by weakness
- increased pulse rate
- drop in BP of 30mm HG below baseline systolic pressure
- decrease in urination
- increased and shallow respirations
170
Steps of collecting information
- Scan and search
- Pay attention
- Remain watchful
- Communicate
