A patient with diabetes has been diagnosed with osteomyelitis. The nurse notes that the patient's right foot is pale and mottled, cool to touch, with a capillary refill of greater than 3 seconds. The nurse should suspect what type of osteomyelitis?
- A. Hematogenous osteomyelitis
- B. Osteomyelitis with vascular insufficiency
- C. Contiguous-focus osteomyelitis
- D. Osteomyelitis with muscular deterioration
Correct Answer: B
Rationale: Osteomyelitis is classified as hematogenous osteomyelitis (i.e., due to blood-borne spread of infection); contiguous-focus osteomyelitis, from contamination from bone surgery, open fracture, or traumatic injury (e.g., gunshot wound); and osteomyelitis with vascular insufficiency, seen most commonly among patients with diabetes and peripheral vascular disease, most commonly affecting the feet. Osteomyelitis with muscular deterioration does not exist.

A nurse is reviewing the care of a patient who has a long history of lower back pain that has not responded to conservative treatment measures. The nurse should anticipate the administration of what drug?
- A. Calcitonin
- B. Prednisone
- C. Aspirin
- D. Cyclobenzaprine
Correct Answer: D
Rationale: Short-term prescription muscle relaxants (e.g., cyclobenzaprine [Flexeril]) are effective in relieving acute low back pain. ASA is not normally used for pain control, due to its antiplatelet action and associated risk for bleeding. Calcitonin and corticosteroids are not used in the treatment of lower back pain.
An elderly female with osteoporosis has been hospitalized. Prior to discharge, when teaching the patient, the nurse should include information about which major complication of osteoporosis?
- A. Bone fracture
- B. Loss of estrogen
- C. Negative calcium balance
- D. Dowager's hump
Correct Answer: A
Rationale: Bone fracture is a major complication of osteoporosis that results when loss of calcium and phosphate increases the fragility of bones. Estrogen deficiencies result from menopause, not osteoporosis. Calcium and vitamin D supplements may be used to support normal bone metabolism, but a negative calcium balance is not a complication of osteoporosis. Dowager's hump results from bone fractures. It develops when repeated vertebral fractures increase spinal curvature.
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.
A nurse is teaching a patient with osteomalacia about the role of diet. What would be the best choice for breakfast for a patient with osteomalacia?
- A. Cereal with milk, a scrambled egg, and grapefruit
- B. Poached eggs with sausage and toast
- C. Waffles with fresh strawberries and powdered sugar
- D. A bagel topped with butter and jam with a side dish of grapes
Correct Answer: A
Rationale: The best meal option is the one that contains the highest dietary sources of calcium and vitamin D. The best selection among those listed is cereal with milk, and eggs, as these foods contain calcium and vitamin D in a higher quantity over the other menu options.
An older adult woman's current medication regimen includes alendronate (Fosamax). What outcome would indicate successful therapy?
- A. Increased bone mass
- B. Resolution of infection
- C. Relief of bone pain
- D. Absence of tumor spread
Correct Answer: A
Rationale: Bisphosphonates such as Fosamax increase bone mass and decrease bone loss by inhibiting osteoclast function. These drugs do not treat infection, pain, or tumors.
