A nurse is caring for a client who is 8 hr postoperative following a left hip arthroplasty. Which of the following laboratory values indicates the nurse should notify the provider?

Choice A reason: Using NSAIDs for pain relief is not a risk factor for osteoporosis. NSAIDs are nonsteroidal anti-inflammatory drugs that are used to treat pain and inflammation. They do not affect bone density or calcium metabolism.

Choice B reason: Age 45 years is not a risk factor for osteoporosis. Osteoporosis is more common in older adults, especially postmenopausal women, but it can affect anyone at any age. The risk of osteoporosis increases with age, but it is not determined by a specific age.

Choice C reason: Smoking cigarettes is a risk factor for osteoporosis. Smoking can reduce bone mass and increase bone loss by interfering with the production and activity of estrogen, which is a hormone that protects bone health. Smoking can also impair blood circulation and oxygen delivery to the bones, which can affect their growth and repair.

Choice D reason: Regular aerobic exercise is not a risk factor for osteoporosis. Aerobic exercise is a type of physical activity that increases the heart rate and improves cardiovascular fitness. Aerobic exercise can also benefit bone health by stimulating bone formation and increasing bone density. Aerobic exercise can also prevent falls and fractures by improving balance and coordination.

Choice A reason: Restricting the client's calorie intake to no more than 2,000 calories per day is not an appropriate action, as it can impair wound healing and increase the risk of infection or malnutrition. The nurse should provide adequate calories and protein to meet the increased metabolic demands and support tissue repair and regeneration.

Choice B reason: Changing sterile gloves between caring for wounds on different areas of the body is an appropriate action, as it can prevent cross-contamination and infection of the burn wounds, which are susceptible to bacterial colonization and sepsis.

Choice C reason: Limiting movement or bending of the client's affected extremities is not an appropriate action, as it can cause contractures, joint stiffness, or muscle atrophy in the burned areas. The nurse should encourage early and frequent range of motion exercises and use splints or positioning devices to maintain functional alignment and mobility.

Choice D reason: Administering a diuretic if the client's urine output falls below 30 mL/hr is not an appropriate action, as it can worsen dehydration, electrolyte imbalance, or renal failure that can occur after severe burns. The nurse should monitor fluid status and urine output closely and administer intravenous fluids as prescribed to maintain adequate hydration and perfusion.
