Q

describe how cellular injury leads to the inflammatory cascade

Q

what are the differences in acute and chronic inflammation

A

acute:
- pain
- redness
- swelling

Q

what chemical are part of inflammatory response? select all that apply

1) bradykinin
2) prostaglandins
3) histamine
4) glucocorticoids

A

1) bradykinin
2) prostaglandins
3) histamine

these all play a part in the systemic reaction after tissue injury. glucocorticoid is a steroid hormone released by the adrenal gland

63
Q

what are the effects of corticosteroids

A

prednisone

(-one is important)

decerase inflammatory and immune response

A

symptom control but not cure

treat broad spctrum of inflammatory and immune conditions like…

71
Q

a nurse is teaching a petient about taking acetaminophen for arthritis pain. which of the following statements is most appropriate?

1) it will only help relieve pain but not the inflammation from arthritis
2) it is appropriate for the treatment of inflammation from arthritis
3) your PCP should consider a narcotic prescription
4) the acetaminophen should be taken on an empty stomach

A

1) it will only help relieve pain but not the inflammation from arthritis

acetaminophen is commonly taken for ateoarthritis, it works as an analgesic but does NOT have any anti-inflammatory properties

72
Q

a patient is taking systemic corticosteroids. which of the following nursing interventions is the most important?

1) assess for s/sx of adrenocortical excess
2) hold cortisone before surgery
3) assess for fluid volum deficit
4) decrease intake of vitamin C

A

1) assess for s/sx of adrenocortical excess

these are stronger and will influence the entire body. s/sx of excess are skin probs (poor wound healing), high BP (fluid retention), bone weakness (osteoporosis), and high glucose. remember you would want to give steroids in times of stress like surgery

73
Q

a patient is receiving prednisone 10mg orally every day to reduce the sx of crohns. which of the following side effects is associated with daily prednisone?

1) atrophy of adrenal gland
2) decrease serum glucose
3) weight loss
4) fluid volume deficit

A

1) atrophy of adrenal gland

taking daily corticosteroids will make the adrenal glands stop producing their own hormones leading to shrinking of the gland. thats why its important to taper off the steroid doses down gradually
