Q

A
  • hypersensitivity
  • immunosuppression
  • hepatic impairment
  • pregnancy/breast feeding

Precautions: renal impairment, active infection

24
Q

What are the nursing considerations and assessments for Methotrexate (Rhematrex)?

A

assess:
- vital signs
- GI –> monitor for diarrhea, pain, stomatitis
- signs of pulmonary toxicity (dry cough - early sign !!)

monitor:
- signs of bone marrow suppression (bleeding gums, bruising, petechiae, melena, hematuria, hematemesis, fatigue, SOB)
- I/Os, weight
- liver enzymes, CBC

Nursing consideration: administer antiemetic prophylactically

25
What are the classifications of Infliximab (Remicade)?
DMARD, tumor necrosis factor antagonist (TNF)
26
What is the role of TNF in RA?
promotes infiltration of neutrophils and macrophages --> resulting in inflammation and joint destruction
27
What is the MOA of Infliximab (Remicade)?
neutralizes TNF (immune mediator in RA) --> suppresses inflammation
28
What are the indications for Infliximab (Remicade)?
active RA, active crohn's disease, psoriasis, ankylosing spondylitis
29
What is the therapeutic effect of Infliximab (Remicade)?
decreased pain/swelling, decreased rate of joint destruction, and improved physical function
30
What are the adverse effects of Infliximab (Remicade)?
- increased risk of serious infections --> M. tuberculosis, fungal infection, opportunistic infections - usage of diabetes, HIV, concurrent immunosuppressant drug will increase the risk of developing an infection while being on this drug - heart failure
31
What are the CI of Infliximab (Remicade)?
- hypersensitivity to Infliximab - active infection Precautions: - pts with a history of tuberculosis, or recurrent infections
32
What are the nursing considerations and assessments for Infliximab (Remicade)?
Assess: - infusion reaction (continuous monitoring of IV site) - monitor CBC frequently --> neutropenia - s/s of infection (fever chills) - edema, weight gain, SOB, crackles --> heart failure Nursing consideration: often used in combo w/ Methotrexate, IV administered
33
What is the classification of Allopurinol (Zyloprim)?
Xanthine oxidase inhibitor
34
What is the MOA of Allopurinol (Zyloprim)?
inhibits the enzyme, Xanthine oxidase (needed for uric acid formation) --> reduces uric acid production in the body
35
What is the indication for Allopurinol (Zyloprim)?
gout
36
What is the therapeutic effect of Allopurinol (Zyloprim)?
- dissolve urate crystals - prevent new crystal formation - prevent disease progression - reduce the frequency of attacks - improve quality of life
37
What are the adverse effects of Allopurinol (Zyloprim)?
well tolerated - hypersensitivity (rash, fever, liver/kidney dysfunction) - mild GI upset - may initially worsen gout attack - kidney stones (increase risk)
38
What are the CI of Allopurinol (Zyloprim)?
caution in pts w/ kidney dysfunction
39
What are nursing considerations and assessments of Allopurinol (Zyloprim)?
discontinue immediately if signs of hypersensitivity, encourage fluid intake
40
What is the normal function of calcium?
nervous system, msk system, cardiovascular system bone: structural integrity of bone
41
Where is calcium usually found in diet?
dairy, non dairy vegetables, calcium fortified processed foods
42
Which group do not get enough of calcium to meet their DRI?
postmenopausal women --> put on supplements
43
Where is calcium stored?
98% in bone - bones are continuously remodeling (resorption and new bone formation)
44
How is calcium absorbed and excreted?
small intestine (vit. D increases absorption), kidneys excrete left over calcium
45
What are the adverse effects of too much calcium?
Hypercalcemia --> 3-4g over a long of periods of time, mostly in those receiving large amounts of vitamin D - GI disturbances (N/V, constipation) - renal dysfunction (polyuria, nephrolithiasis) - CNS effects (lethargy, depression) - change in skeletal muscle tone - cardiac dysrhythmias - risk of vascular calcification, MI, stroke
46
What are the nursing considerations of calcium?
variety of supplements --> consider the amount of elemental calcium and the pts dietary intake - administration
47
What is the function of vitamin D?
increases plasma calcium levels - increase calcium resorption from bone - decrease calcium excretion by the kidneys - increase calcium absorption from the intestine
48
How do we get vitamin D?
sunlight (produced naturally), vitamin D2 (found in plants) used in medicine, supplements, and fortification of foods
49
What is the adverse effect of vitamin D?
hypercalcemia
50
What is the classification of Alendronate (Fosamax)?
Bisphosphonate
51
What is the MOA of Alendronate (Fosamax)?
reduces the number and activity of osteoclasts
52
What are the indications for Alendronate (Fosamax)?
osteoporosis in postmenopausal women, glucocorticosteroids induced OP, OP in men
53
What are the therapeutic effect of Alendronate (Fosamax)?
reversal of the progression of OP with decreased fractures NOTE: often used for less than 5yrs --> effects can last 10 yrs
54
What are the adverse effects of Alendronate (Fosamax)?
- esophagitis (occurs with prolonged contact w/ esophageal mucosa if the drug fails to pass completely into the esophagus) - MSK pain (can occur with initial dose/month after --> not a reason to stop) -- notify the prescriber to manage time - RARE: ocular inflammation, atypical femur fractures (increase with long term use
55
What are the nursing considerations of Alendronate (Fosamax)?
- administration: morning, empty stomach, before breakfast, with only water, no food or drinks for 30 mins after (maximize bioavailability) - minimize risk of esophageal injury: full glass of water, remain upright (sitting/standing) at least 30 mins, avoid chewing or sucking on alendronate tablets
