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.)
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 A
Explanation
A. Palpating the femoral pulse is an essential part of assessing the neurovascular status of a client with a femur fracture. The presence and strength of the femoral pulse can indicate adequate blood flow to the lower extremity.
B. While measuring the circumference of the thigh can provide some information about swelling or changes in the size of the limb, it does not directly assess neurovascular status.
C. Monitoring the client's calf for edema is important for assessing for signs of deep vein thrombosis (DVT) or venous insufficiency, but it is not the primary technique for assessing neurovascular status.
D. Instructing the client to wiggle his toes is a way to assess motor function and nerve function, which is part of the neurovascular assessment. However, it is not the initial step in assessing neurovascular status in a client with an unrepaired femur fracture. The femoral pulse should be assessed first to ensure adequate blood flow.
Correct Answer is D
Explanation
A. Rowing - This activity can put strain on the lower back and may exacerbate low back pain.
B. Tennis - This sport involves a lot of twisting and sudden movements, which can potentially worsen low back pain.
C. Canoeing - While generally a low-impact activity, it still requires core stability which could potentially aggravate low back pain.
D. Swimming - Swimming is a highly recommended exercise for individuals with low back pain. It is a low-impact activity that helps strengthen the muscles in the back, as well as other parts of the body, without putting excessive strain on the spine. Additionally, the buoyancy of water provides support, reducing the impact on the joints.
