Musculoskeletal Disorders

• Rheumatoid Arthritis - autoimmune

• Osteoarthritis - age, injury, heredity

• Osteoporosis - age, lifestyle, heredity

DMARDs

• Slows RA progression & joint degeneration

• Immunosuppress

• Methotrexate

  • Increase risk of infection, bone marrow suppression

  • Avoid NSAIDs, but take folic acid

  • Can take 3-6 weeks for therapeutic effect

  • Hydration

Multiple Choice

A client taking methotrexate for rheumatoid arthritis reports mouth sores and fatigue. Recent labs show:

WBC 2,800/mm³ (normal: 4,500–11,000)

ALT 110 U/L (normal: 7–56)

Which nursing action is most appropriate?

• Administer methotrexate with food to reduce nausea

• Hold the dose and notify the provider

• Encourage the client to drink extra water

• Schedule the next dose as prescribed

​Resorption vs Reabsorption

SERMs

• Prevent and treat postmenopausal osteoporosis

• Raloxifene

  • Activates and blocks estrogen receptors

  • Increases hot flashes and risk for stroke or DVT

  • Take extra calcium and Vitamin D

  • Monitor bone density, for blood clots, and cholesterol

Bisphonates

• Prevent and treat postmenopausal osteoporosis

• Alendronate

  • Decreases bone resorption

  • Esophagitis, vision changes, osteonecrosis of jaw

  • Take with water, sit/stand for 30m, analgesic for mild pain

  • Avoid if difficulty swallowing, unable to sit/stand, renal insufficiency, upper GI disorder

Fill in the Blanks

A

study should be performed prior to starting alendronate.

Calcitonin

• Treats postmenopausal osteoporosis and hypercalcemia

• Calcitonin-Salmon

  • Decreases bone resorption; inhibits osteoclasts and increases calcium excretion

  • Hypersensitivity; hypocalcemia; epistaxis; site irritation

  • Allergy test before admin; rotate inj sites and nares

  • Diet high in calcium and Vitamin D

The client should monitor and report a

while taking calcitonin.

Calcium Supplements

• Calcium deficiency

• Calcium Citrate

  • Dietary supplement

  • Take with Vitamin D to increase absorption

  • Hypercalcemia -> kidney stones

  • Monitor urine output, flank pain, hematuria, decreased GI motility

Pain & Inflammation

• Migraines

Adjuvant Meds for Pain

Adjuvant meds are used with a primary pain medication to increase pain relief.
Reduces the amount of opioids necessary to achieve pain relief, thereby reducing adverse effects (respiratory depression, sedation, constipation).

  • Ibuprofen

  • Aspirin

  • Celecoxib

• Acetaminophen - relieves pain & fever

​Non-opioid

• Tramadol - analgesic for mild-to-moderate pain

• Morphine - mod - severe pain

• ​"I should take the medicine on an empty stomach."
  

• "I will expect to develop a fever while taking this medicine."
  

• ​Stops the production of uric acid, reducing future attacks

• Allopurinol

  • Hypersensitivity, GI upset, thrombocytopenia

  • Monitor uric acid, liver & kidney function

  • Drink water!

  • Increases anticoag effects

​Antigout

• ​Delay RA progression; anti-inflammatory effects

• Prednisone

  • Hyperglycemia; immunosuppression; bone loss; cataracts

  • Monitor BS, vitals, K and Na

  • Weight-bearing exercises

  • Report s/s of infection, weight gain & edema

  • Take with food, taper dose slowly

​Glucocorticoid (cortisol)
