24
Q

Precautions for methotrexate (Rheumatrex)

Hepatic fibrosis
Bone marrow suppression (risk for bleeding, infection, anemia)
GI ulceration
Pneumonitis

26
Q

Nursing considerations for methotrexate (Rheumatrex)

A

Assess vital signs
GI assessment (monitor for diarrhea, pain, stomatitis)
Signs of bone marrow suppression → bleeding gums, bruising, petechiae, melon, hematuria, hematemesis, fatigue shortness of breath

Administer antiemetic prophylactically
Liver enzymes, CBC

27
Q

Tumour necrosis factor

A

In rheumatoid arthritis, tumour necrosis factor (TNF) plays a large role in promoting infiltration of neutrophils and macrophages which results in inflammation and joint destruction

28
Q

Infliximab (Remicade) classification

A

Disease Modifying Antirheumatic Drug (DMARD)
Tumor Necrosis Factor Antagonist

29
Q

Infliximab (Remicade) MOA

A

Neutralizes TNF, an immune mediator in RA, thereby suppressing inflammation

30
Q

Infliximab (Remicade) indications

A

Active rheumatoid arthritis, active Crohn’s disease, psoriasis, ankylosing spondylitis

31
Q

Therapeutic effect of infliximab (Remicade)

A

Decreased pain and swelling, decreased rate of joint destruction and improved physical function

32
Q

Additional info of infliximab (Remicade)

A

Often used in combination with Methotrexate
IV administered

33
Q

Adverse effects of infliximab (Remicade)

A

Immunosuppression → increased risk of serious infections (especially infections caused by M. Tuberculosis), fungal infections, and opportunistic infections
-Because TNF normally plays a role in response to infection, drugs that neutralize this factor, risk of infection increases
-Diabetes, HIV, and concurrent immunosuppressant drug use will increase the developing an infection while on the drug

Heart failure

34
Q

Contraindications of infliximab (Remicade)

A

Hypersensitivity to Infliximab
Active infection
Use cautiously in patients with a history of tuberculosis, patients with recurrent infections

35
Q

Nursing considerations for infliximab (Remicade)

A

Infusion reaction
- Continuous monitoring of IV site
- Minor vs Severe

Infection
- Signs of new onset
- Fever/ chills

Neutropenia
- CBC monitored frequently

Heart failure
- Edema, weight gain, SOB, crackles

36
Q

A nurse teaches a patient who is to start taking infliximab (Remicade) for rheumatoid arthritis. Which of these cardiac findings should the nurse instruct the patient to report as a complication of this treatment?
a. Calf pain
b. Pedal edema
c. Cool, pale toes
d. Clubbed fingernails

A

b. Pedal edema

37
Q

A patient is taking methotrexate (Rheumatrex) for rheumatoid arthritis. Which therapeutic action should a nurse expect if the medication is having the desired effect?
a. Selective inhibition of cyclooxyrgenase
b. Neutralization of tumour necrosis factor
c. Inhibition of T-cell activation
d. Suppression of T and B lymphocytes

A

d. Suppression of T and B lymphocytes

38
Q

Allopurinol (Zyloprim) classification

A

39
Q

Allopurinol (Zyloprim) MOA

A

Xanthine oxidase is an enzyme required for uric acid formation. By inhibiting this enzyme, thereby reducing the production of uric acid in the body

Indication for allopurinol (Zyloprim)

A

Gout

41
Q

Therapeutic effect of allopurinol (Zyloprim)

A

Dissolve uric crystals, prevent new crystal formation, prevent disease progression, reduce frequency of attacks, improve quality of life

42
Q

Adverse effects of allopurinol (Zyloprim)

A

Generally, well tolerated
Hypersensitivity → rash, fever, liver and kidney dysfunction
Mild GI upset
May initially worsen gout attack
Kidney stones

43
Q

Contraindications of allopurinol (Zyloprim)

A

Use with caution in patients with kidney dysfunction
Discontinue immediately if signs of hypersensitivity
Encourage fluid intake

44
Q

Normal function of calcium

A

Nervous system
MSK system
Cardiovascular system

45
Q

Where is vitamin D and calcium absorbed?

A

In the small intestine

46
Q

Hypercalcemia

A

3-4g a day over long periods of time
Most likely in those also receiving large amounts of vitamin D
GI disturbance: N/ V/ constipation
Renal dysfunction (polyuria, nephrolithiasis)
CNS effects (lethargy, depression)
Cardiac dysrhythmias
Risk of vascular calcification, MI and stroke

47
Q

Role of vitamin D for calcium

A

Increases plasma calcium levels
- Increases calcium reabsorption from bone
- Decreases calcium excretion by the kidney
- Increases calcium absorption from the intestine
Produced naturally in humans when our skin is exposed to sunlight
Vitamin D2 is a form of vitamin D that occurs in plants and is used for medications and supplements and to fortify foods

48
Q

Alendronate (Fosamax) classification

A

Bisphonate

49
Q

Alendronate (Fosamax) MOA

A

Reduces the number and activity of osteoclasts

50
Q

Contraindications for alendronate (Fosamax)

A

OP in postmenopausal women, GIOP, OP in men

51
Q

Therapeutic effects of alendronate (Fosamax)

A

Strengthens bone and reduces risks of fractures associated with osteoporosis

52
Q

Adverse effects of alendronate (Fosamax)

A

Esophagitis: occurs with prolonged contact with the esophageal mucosa if the drug fails to pass completely into the esophagus
MSK pain: can occur with initial dose or month after. Not a reason to stop - notify the prescriber and manage the pain. Often resolves with time
RARE: ocular inflammation, atypical femur fractures

53
Q

Administration of alendronate (Fosamax)

A

Maximize bioavailability (morning, empty stomach, before breakfast, with only water, no food or drink for 30 mins after)

Minimize risk of esophageal injury:
Take with a full glass of water
Remain upright (sitting or standing) for at least 30 mins
Avoid chewing or sucking on alendronate tablets
