5 Relate the diagnosis of pneumonia to the two stages of respiration - external respiration and gas transport. Include the following in your answer.
a Describe what occurs during normal:
1 external respiration
2. gas transport.
b Mr Marconi’s blood results indicate that he has a low oxygen and high carbon dioxide, relate this finding to the effects of pneumonia on external respiration and gas transport. (150 words)
6 Relate the pathophysiology of his condition to the reason for his elevated respiratory rate. Describe the steps involved in homeostasis of respiratory rate including the following aspects in your answer:
a Name the 2 respiratory gases detected in the blood,
b Name the receptor sites where these gases are detected.
c The location of the control centre
d Why Mr Marconi would have an increased respiratory rate due to pneumonia. (200 words)
7 A sputum test is ordered for culture and sensitivity (also called susceptibility). Describe what each of these tests are evaluating and how the results relate to medication prescription. (50-100 words)
You are administering 08:00 medications to Mr Marconi, You note that the Registered Nurse in Emergency has already administered his morning Lantus at 07:30. He is due for his Ramipril.
8 Describe the steps in the renin-angiotensin-aldosterone pathway (RAAS) and how Ramipril affects this process. (100-150 words)
Include in your answer the following factors:
a What triggers the release of renin in the kidneys?
b What substance does renin target in the liver?
c How is angiotensinogen converted to angiotensin I?
d What is the enzyme that converts angiotensin I to angiotensin II and where is this normally found?
e Discuss two effects that angiotensin II has on blood pressure.
f What action does Ramipril have on the RAAS pathway?
During the morning Mr Marconi seems quite despondent, sleeping most of the time. He is refusing to eat saying that he feels too sick and just wants to sleep. At 09:15 he suddenly becomes diaphoretic, the Enrolled Nurse records the vital signs on the ADDS chart. His bedside glucometer test measures the blood sugar level as 3.1mmol
9 Explain the effects of insulin on blood sugar. Include the target sites and function of insulin (100-
150 words)
10 Review the observation chart and events leading up to his deterioration (information in the grey boxes in the case study). Answer the following in relation to Mr Marconi’s deterioration at 09:15
a List the vital signs recorded and identify the readings that are abnormal. (You only need to list the vital signs at the time he deteriorated Review both pages of the ADDS vital signs chart)
b Review the events that have occurred during the morning (information in the grey boxes on this case study) and discuss the factors that contributed to his decreased level of consciousness (AVPU scale).
c Discuss the medication that may have caused him to deteriorate.
The Registered Nurse convinces Mr Marconi to drink orange juice and eat a sandwich and his symptoms resolve. The doctor reviews Mr Marconi and changes his insulin to a sliding scale. He is commenced on Lantus again 2 days later when he is feeling better.
