Unit 1

Question 1

Describe some of the personal and emotional consequences of IRDS

Answer 1

1. Toll on Child:
   * Brain Damage (little to no oxygen entering the blood to the brain)

• Developmental disorders (eg: possible onset of blindness)
  2. Toll on parents: guilt associated w/ genetic-associated syndrome
• Financial stress on parents
• Emotional pain: onset of syndrome in premature babies, child immediately taken to ICU

Question 2

What is the Pathology of IRDS?

Answer 2

Pulmonary cells lack sufficient amount of surfactants which makes the lungs less flexible (decreased compliance) so the alveoli don’t open correctly.
Comprised alveoli causes hypoxia, pulmonary anemia, blood acidity

Question 3

What are some ways IRDS treated in a preterm (premature) baby?

Answer 3

1. Glucocorticoids delivered to mother to aid in the development of surfactants
2. Surfactant Replacement Therapy- artificial surfactant administered through Endotracheal Tube (ET) to the infant
   - Continuous Positive Airway Pressure (CPAP) is a Mechanical airway machine that delivers a continuous flow of oxygen into the baby’s lungs to keep airway open

Question 4

What role does lung surfactant play in normal breathing?

Answer 4

Pulmonary Surfactant is a mixture of phospholipids (PL) and Proteins (SP) that reduce surface tension at the air-liquid interface in the alveolus.

Surfactant allows the lungs to properly expand

Question 5

What is the link between IRDS and BIOC 4580 Membrane Biochemistry?

Answer 5

Pulmonary surfactant creates a membrane in the alveoli

Secretion of surfactant is mediated by membrane transport (exocytosis, lipoproteins)

Question 6

Long terms effects of IRDS on those who survive the condition

Answer 6

1. Broncho-pulmonary Dysplasia(chronic lung disease): scarring of the lung
2. Increased likelihood of asthma, impaired vision, learning/ behaviour problems, developmental abnormalities

Question 7

Tuckman’s 4 stages of Team Growth: 1st Stage

Answer 7

Forming: the team is being formed and members are getting to know each other, decide roles and define strengths

Feelings: members feel excitement, optimism and some anxiety about the work at hand

Behaviour: team is defining the task; how task will be accomplished, group behaviour.
At the forming stage little is accomplished towards group’s goal

Question 8

Tuckman’s 4 stages of Team Growth: 2nd Stage

Answer 8

Storming- Understanding phase, there is dysfunction between members

Feelings: members feel frustrated towards difficulty of task
Members become Impatient and take the lead doing things their way.

Behaviour: team may play less attention to details
Team is Arguing and Increased Tension, Competitive
Members become defensive and be resistant towards the task

Question 9

Tuckman’s 4 stages of Team Growth: 3rd Stage

Answer 9

Norming- Team learns to work together

Feelings: members feel they are able to provide constructive criticism
Members begin to feel accepted by the team and has willingness to be part of the team.

Behaviour: Establishing/Maintaining team ground rules
Avoiding conflict
Sharing of personal and professional issues

Question 10

Tuckman’s 4 stages of Team Growth: 4th Stage

Answer 10

Performing- team has settled the relationship and expectations and can perform effectively

Feelings: understanding of team members strengths and weaknesses to reach group’s goal
*Members can Reflect on both their own and groups process/progress

Behaviour: team members work towards preventing or works through team conflict
A Bond has been made with the team
