A nurse is caring for a client who is postoperative hip arthroplasty and has a new prescription for enoxaparin 1 mg/kg/dose subcutaneously every 12 hr. The client weighs 95 lbs. How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["43.2"]

- To calculate the dose of enoxaparin, first convert the client's weight from pounds to kilograms by dividing by 2.2.

- 95 lbs / 2.2 = 43.18 kg

- Then, multiply the weight in kilograms by the prescribed dose of 1 mg/kg. - 43.18 kg x 1 mg/kg = 43.18 mg

- Finally, round the answer to the nearest tenth of a milligram.

- 43.18 mg ≈ 43.2 mg

- Therefore, the nurse should administer 43.2 mg of enoxaparin per dose subcutaneously every 12 hours.

Correct Answer is B

Explanation

A. Drying time is typically shorter with a synthetic cast compared to a plaster cast. Synthetic casts are designed to set faster, reducing the time the patient needs to remain immobilized during casting.

B. A synthetic cast is generally lighter in weight than a plaster cast. This can be more comfortable for the patient and may reduce the risk of muscle atrophy or discomfort associated with the cast's weight.

C. A plaster cast does not necessarily require expensive equipment for application, and both plaster and synthetic casts can be applied using relatively simple and cost-effective methods.

D. The effectiveness of immobilization is not significantly different between plaster and synthetic casts. Both types of casts can provide adequate immobilization for bone fractures, and the choice between them may depend on factors like patient preference, the type of fracture, and other clinical considerations.

A. Fat embolism syndrome B. Pulmonary embolism C. Acute compartment syndrome D. Osteomyelitis

Correct Answer is C

Explanation

A. Fat embolism syndrome - This is characterized by respiratory distress, altered mental status, and petechial rash. It is not associated with increasing edema.

B. Pulmonary embolism - This occurs when a blood clot (usually from the legs) travels to the lungs and can present with symptoms like chest pain, shortness of breath, and rapid heart rate. It is not associated with increasing edema around a fracture site.

C. Acute compartment syndrome - This is a serious condition that occurs when increased pressure within a muscle compartment impairs blood supply, leading to tissue ischemia and necrosis. Increasing edema is an early sign of compartment syndrome.

D. Osteomyelitis - This is an infection of the bone and is not typically associated with increasing edema around a fracture site. It may present with local signs of infection like warmth, redness, and tenderness.
