Osteoporosis Reference
Osteoporosis is silent until a bone breaks — often from a fall that shouldn’t have broken anything, or no fall at all. The nursing levers are screening awareness, medication teaching that actually gets followed, and fall prevention, because the first fragility fracture predicts the next one.
Educational use only. Screening intervals, medication selection, and supplement dosing are provider-directed; this reference covers nursing knowledge and teaching points. This material supports nursing education and exam review. It is not medical advice and is not a substitute for clinical judgment, institutional policy, or medical direction. Always follow facility protocols and current provider orders.
Risk Factors
| Non-Modifiable | Modifiable | Medications & Disease |
|---|---|---|
| Female sex; postmenopausal estrogen loss; age; small frame; White or Asian ancestry; family history | Low calcium/vitamin D intake; sedentary lifestyle; smoking; excess alcohol; low body weight | Long-term corticosteroids (the big one); PPIs; some anticonvulsants; hyperthyroidism; CKD; RA; malabsorption |
Diagnosis & Presentation
DXA (bone density) scan reports a T-score: −1.0 and above is normal, −1.0 to −2.5 is osteopenia, −2.5 and below is osteoporosis. Screening is standard for women 65 and older, earlier with risk factors.
Clinically, osteoporosis announces itself as a fragility fracture — a break from standing height or less — most often hip, vertebra, or wrist. Vertebral compression fractures may present only as height loss (more than an inch), progressive kyphosis, or sudden mid-back pain with ADLs. New back pain in a thin, older adult deserves that thought.
Bisphosphonates — The Teaching That Matters
Oral administration rules (alendronate, risedronate)
First thing in the morning, empty stomach, with a full glass of plain water only — then remain upright (sitting or standing) and take nothing else by mouth for at least 30 minutes (60 for ibandronate). Food, coffee, juice, and other medications block absorption; lying down risks esophageal irritation and erosion.
Report immediately
New difficulty or pain with swallowing, retrosternal burning (esophagitis); jaw pain or numbness (osteonecrosis of the jaw — rare, dental work raises risk); new thigh or groin pain (atypical femoral fracture — also rare). Dental check-ups before starting long-term therapy are commonly advised.
Other agents you’ll see
Denosumab (subcutaneous every 6 months — missing a dose risks rebound vertebral fractures, so adherence is the teaching), raloxifene (VTE risk — report calf swelling), teriparatide (anabolic daily injection), and calcitonin. Calcium and vitamin D ride alongside nearly all of them.
Prevention & Lifestyle Teaching
Weight-bearing and resistance exercise — walking, stair climbing, light weights — signals bone to remodel; swimming and cycling, good as they are for the heart, do not load bone. Adequate dietary calcium (dairy, fortified foods, leafy greens) and vitamin D, smoking cessation, and moderating alcohol round out the bone side.
The fall side is just as important: home hazard sweep (rugs, cords, lighting, grab bars), vision checks, footwear with grip, medication review for sedating or orthostatic agents, and balance work like tai chi. In the patient who already has osteoporosis, a fall prevented is a fracture prevented.
NCLEX Pearls
- ✦Oral bisphosphonate = empty stomach, full glass of plain water, upright and NPO for 30+ minutes. Every element appears on exams.
- ✦T-score −2.5 or below = osteoporosis; −1.0 to −2.5 = osteopenia.
- ✦Long-term corticosteroid therapy is the highest-yield medication risk factor for secondary osteoporosis.
- ✦Weight-bearing exercise builds bone; swimming does not — a favorite distractor.
- ✦Height loss and kyphosis suggest silent vertebral compression fractures.
