A nurse is reviewing the pathophysiology that may underlie a patient's decreased bone density. What hormone should the nurse identify as inhibiting bone resorption and promoting bone formation?
- A. Estrogen
- B. Parathyroid hormone (PTH)
- C. Calcitonin
- D. Progesterone
Correct Answer: C
Rationale: Calcitonin inhibits bone resorption and promotes bone formation, estrogen inhibits bone breakdown, and parathyroid increases bone resorption. Estrogen, which inhibits bone breakdown, decreases with aging. Parathyroid hormone (PTH) increases with aging, increasing bone turnover and resorption. Progesterone is the major naturally occurring human progestogen and plays a role in the female menstrual cycle.

A nurse is providing care for a patient who has a recent diagnosis of Paget's disease. When planning this patient's nursing care, interventions should address what nursing diagnoses?
- A. Impaired Physical Mobility
- B. Acute Pain
- C. Disturbed Auditory Sensory Perception
- D. Risk for Injury
- E. Risk for Unstable Blood Glucose
Correct Answer: A,B,C,D
Rationale: Patients with Paget's disease are at risk of decreased mobility, pain, hearing loss, and injuries resulting from decreased bone density. Paget's disease does not affect blood glucose levels.
A nurse is caring for an adult patient diagnosed with a back strain. What health education should the nurse provide to this patient?
- A. Avoid lifting more than one-third of body weight without assistance.
- B. Focus on using back muscles efficiently when lifting heavy objects.
- C. Lift objects while holding the object a safe distance from the body.
- D. Tighten the abdominal muscles and lock the knees when lifting of an object.
Correct Answer: A
Rationale: The nurse will instruct the patient on the safe and correct way to lift objects using the strong quadriceps muscles of the thighs, with minimal use of the weak back muscles. To prevent recurrence of acute low back pain, the nurse may instruct the patient to avoid lifting more than one-third of his weight without help. The patient should be informed to place the feet a hip-width apart to provide a wide base of support, the person should bend the knees, tighten the abdominal muscles, and lift the object close to the body with a smooth motion, avoiding twisting and jerking.
An older adult patient sought care for the treatment of a swollen, painful knee joint. Diagnostic imaging and culturing of synovial fluid resulted in a diagnosis of septic arthritis. The nurse should prioritize which of the following aspects of care?
- A. Administration of oral and IV corticosteroids as ordered
- B. Prevention of falls and pathologic fractures
- C. Maintenance of adequate serum levels of vitamin D
- D. Intravenous administration of antibiotics
Correct Answer: D
Rationale: IV antibiotics are the major treatment modality for septic arthritis; the nurse must ensure timely administration of these drugs. Corticosteroids are not used to treat septic arthritis and vitamin D levels are not necessarily affected. Falls prevention is important, but septic arthritis does not constitute the same fracture risk as diseases with decreased bone density.
An 80-year-old man in a long-term care facility has a chronic leg ulcer and states that the area has become increasingly painful in recent days. The nurse notes that the site is now swollen and warm to the touch. The patient should undergo diagnostic testing for what health problem?
- A. Osteomyelitis
- B. Osteoporosis
- C. Osteomalacia
- D. Septic arthritis
Correct Answer: A
Rationale: When osteomyelitis develops from the spread of an adjacent infection, no signs of septicemia are present, but the area becomes swollen, warm, painful, and tender to touch. Osteoporosis is the most prevalent bone disease in the world. Osteomalacia is a metabolic bone disease characterized by inadequate mineralization of bone. Septic arthritis occurs when joints become infected through spread of infection from other parts of the body (hematogenous spread) or directly through trauma or surgical instrumentation.
An orthopedic nurse is caring for a patient who is postoperative day one following foot surgery. What nursing intervention should be included in the patient's subsequent care?
- A. Dressing changes should not be performed unless there are clear signs of infection.
- B. The surgical site can be soaked in warm bath water for up to 5 minutes.
- C. The surgical site should be cleansed with hydrogen peroxide once daily.
- D. The foot should be elevated in order to prevent edema.
Correct Answer: D
Rationale: Pain experienced by patients who undergo foot surgery is related to inflammation and edema. To control the anticipated edema, the foot should be elevated on several pillows when the patient is sitting or lying. Regular dressing changes are performed and the wound should be kept dry. Hydrogen peroxide is not used to cleanse surgical wounds.
