A 70-year-old female client presents to the clinic with complaints of joint stiffness and pain. Which assessment finding would be most significant in identifying risk factors for osteoporosis?
1Body mass index of 28 kg/m²
2History of smoking 1 pack per day for 30 years✓ 정답
3Daily calcium intake of 800 mg
4Sedentary lifestyle with minimal weight-bearing exercise
해설
Smoking is a significant modifiable risk factor for osteoporosis, particularly in postmenopausal women. Other options (BMI 28, calcium intake 800 mg, sedentary lifestyle) are less concerning risk factors.
Clinical Judgment
This question is in the Recognize Cues stage, focusing on Risk Factor Assessment. The key is to identify the "most significant" risk factor for osteoporosis. Risk factors for osteoporosis in postmenopausal women are broadly divided into non-modifiable factors (age, sex, family history) and modifiable factors. Among these, smoking is the strongest independent risk factor, having a direct and significant negative impact on bone health. While the other options increase risk, their influence and immediate importance are lower than smoking.
Memory Tip:
To remember the major risk factors for osteoporosis, think of the acronym SALES, which stands for SMOKING, ALCOHOL, LOW WEIGHT, ESTROGEN LOSS, STEROIDS. Smoking (S) comes first.
KR vs US:
In Korea, osteoporosis risk assessments tend to focus more on insufficient calcium/vitamin D intake or low body mass index (BMI) rather than smoking. However, in NGN/US clinical practice, based on Evidence-Based Practice, smoking is emphasized as the top modifiable risk factor. Nurses must understand and educate patients beyond simply stating it is 'bad,' explaining the physiological mechanisms by which smoking leads to decreased bone density and increased fracture risk (e.g., disruption of estrogen metabolism, inhibition of osteoblast function, increased oxidative stress).

Clinical Practice Guide
A comprehensive assessment of bone health in postmenopausal women should include the following:
1. Risk factor screening: Assessment of 10-year major fracture risk using tools such as FRAX®.
2. Notify HCP! If high-risk factors such as smoking history, long-term steroid use, or abnormal weight loss are identified, report to the physician and discuss establishing an active intervention plan.
3. Education: Provide education on calcium (1200 mg/day) and vitamin D (800-1000 IU/day) intake, the importance of weight-bearing exercise, and fall prevention.
Caution:
Be careful of traps in SATA (Select All That Apply) questions. For the question "What are the risk factors for osteoporosis?", all options could be correct. However, if the question asks for the "most significant" factor, as in this case, you must judge the magnitude of impact based on evidence. Also, remember that a high BMI can be a protective factor.
핵심 개념
Osteoporosis — Osteoporosis. A metabolic bone disease in which the bone's microstructure deteriorates and bone density decreases, leading to weakened bones and an increased risk of fractures.
Postmenopausal — Postmenopause. A period when ovarian function ceases and estrogen production significantly decreases, marking a major turning point where rapid bone loss begins in women.
Risk Factor — Risk factor. A characteristic, behavior, or exposure that increases the likelihood of developing a particular disease or condition.
Bone Mineral Density — Bone density. A measurement of the amount of minerals (mainly calcium and phosphorus) per unit area of bone. A key criterion for diagnosing osteoporosis.
Estrogen Deficiency — Estrogen deficiency. This is the main hormonal change of menopause, where the protective effect of estrogen that suppresses the activity of osteoclasts (cells that absorb bone) disappears, leading to accelerated bone loss.
