Osteoporosis Risk Factors

Low calcium and vitamin D intake, Age (women after menopause), lifestyle factors such as smoking, excessive alcohol intake, sedentary life, immobility, Caucasian and Asian women, family history, underweight/malabsorption disorder, Long-term use of corticosteroids, anticonvulsants, levothyroxine, or PPIs.

Osteoporosis Testing

Bone Density Test- Dual-Energy X-Ray Absorptiometry (DEXA), this process takes X-Ray images, measuring calcium, and other minerals in the bones.

Topical diclofenac sodium gel has been FDA approved for the use of osteoarthritic joint pain in the hands and knees

Methotrexate & Colchicine

typically prescribed for treating RA and gout, respectively, may also be considered for some patients with OA who are refractory to other treatments. The pathophysiologic antecedents of these diseases are like those in OA, and it is believed that may explain the effectiveness of these medications in some select patients with OA

Visco supplementation

the injection of gel-like substances (hyaluronates) into a joint (intra-articular), is thought to supplement the viscous properties of synovial fluid. These Viscos supplements aim to prevent the loss of cartilage and repair chondral defects but lack strong evidence that support their use

Diclofenac

Reversibly inhibits COX-1 and COX-2 to produce an anti-inflammatory response. 99% bound to albumin. Transdermal patch has half-life of 12 hours. Oral preparation is 1-2 hours. Used to relieve inflammatory symptoms of RA, OA, and ankylosing spondylitis

Foods to Avoid in Gout

Alcohol, large meals, especially red meat can lead to increases in free fatty acid concentrations and trigger gout attacks

Probenecid

Uricosuric Agent that inhibits renal reabsorption of urates and increases the urinary excretion of uric acid. Prevents tophi formationBe alert for nausea and rash

Colchicine (Mitigare, Colcrys)

Antigout agent.MOA: Lowers the deposition of uric acid and interferes with leukocyte infiltration, thus reducing inflammation. Does not alter serum or urine levels of uric acid. Used for both acute and chronic managementFor acute management - administer when attack begins. Dosage increased until pain is relieved, or diarrhea develops - then stop med. For Chronic Management - Causes GI upset in most patientsRelieves acute attacks and prevents future but DOES NOT decrease inflammation.Side effects include vomiting, abdominal pain, and diarrhea BLACK BOX WARNING OF RISK OF BONE MARROW SUPPRESSIONPatient education is to take with full glass of water, increase fluid intake to 2-3 L/day (may produce urine output of 2 L/day), avoid organ meats, and it does take several months to work

Allopurinol (Aloprim, Zyloprim, Lopurin), & Febuxostat

Uric acid inhibitor/Xanthine oxidase inhibitorsMOA: Interrupt the breakdown of purines before uric acid is formed. Inhibit xanthinoxidase because uric acid formation is blocked. Prevents gout attacks but does not help with acute attacks.Side effects include nausea, vomiting, abdominal pain, diarrhea, and skin rashes (may indicate SJS - stop med)Patient education is to take with full glass of water, increase fluid intake to 2-3 L/day (may produce urine output of 2 L/day), avoid organ meats, and it does take several months to work. Uric acid deposits can cause kidney stones (fluids help prevent this)BLACK BOX WARNING Taking this med with aspirin increase uric acid levels TAKE ACETAMINOPHEN INSTEAD

Environmental factors such as pollution and smoking, family history of first-degree relatives, and illnesses such as bacterial and viral illnesses.

Nursing Education for Rheumatoid Arthritis (RA)

Pain, fatigue, and depressive symptoms can interfere with the patients ability to learn. They should be addressed before education is began.

Patient Education & Self-Care for Rheumatoid Arthritis (RA)

Maintain as much independence as possible. Joint pain will be worse in the morning but will improve with movement. - Take meds accurately and safely. Teach side effects, and how to use meds (topic is sparingly, avoiding open skin). Use adaptive devices correctly. - Provide genetic counseling for young women. - Exercise should be scheduled with periods of rest in between activities and avoid high impact exercise. Water exercises are good. - Maintain skin integrity - give sleep tips (avoid caffeine and heavy meals close to bedtime) - Anemia - helps to eat dark leafy green veggies and protein from meat.

Azathioprine (Imuran)

Decreases the production of antibodies at the cellular level. Directly effects the disease. The one that really makes a difference in the disease process where others just treat symptoms.

Infiltration

Can occur from the IV cannula dislodging, or perforation of the vein wall. Characterized by edema around insertion site, leakage of IV fluid from the insertion site, discomfort and coolness in the affected area, and significant decrease in flow rate. Sloughing can occur when solution is really irritating.

Extravasation

Often caused by vasopressors, K+, and calcium preparations or chemotherapeutic agents. Characterized by pain, burning, redness, blistering, inflammation, and necrosis.

Thrombophlebitis

The presence of clot plus inflammation in the vein. Evidenced by localized swelling around insertion site or along the path of a vein. Immobility of the extremity may occur because of swelling, discomfort, and sluggish flow rate, fever, malaise, and leukocytosis

Hematoma

Blood leaks into tissues surrounding the IV insertion site. Results if the vein wall is perforated during venipuncture, the needle slips out of the vein, or the cannula is too large. Symptoms include ecchymosis, immediate swelling at the site, and leakage of blood at the insertion site.

Respiratory Buffer Systems

Hyperventilation. The increase RR helps blow out excessive hydrogen ions (decreases hydrogen ions). Hypoventilation occurs to increase hydrogen ions.

Kidney Buffer Systems

Produce more bicarbonate if needed. If there are high hydrogen ions, bicarbonate reabsorption and production occurs. If there is low hydrogen ions, bicarbonate excretion occurs
