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. Holding the wrist at a 90-degree flexion is known as Phalen's maneuver, which is a test for carpal tunnel syndrome. This position puts pressure on the median nerve, potentially reproducing the client's symptoms.

Explanation
A. Cool extremities are not typically associated with carpal tunnel syndrome. They may be a sign of poor circulation, but this is not a specific finding for carpal tunnel syndrome.
B. Decreased radial pulse is not a characteristic finding of carpal tunnel syndrome. It may indicate issues with blood flow to the hand but is not specific to this condition.
C. Positive Chvostek's sign is associated with hypocalcemia and involves facial muscle twitching when the facial nerve is tapped. It is not related to carpal tunnel syndrome.
