A client had a total hip arthroplasty. Which of the following prescriptions should the nurse verify with the provider?
- A. Administer enoxaparin 30 mg subcutaneously every 12 hr
- B. Place a wedge or pillow between the client's legs when turning.
- C. Instruct the client to restrict flexion of the hip past 120°.
- D. Encourage the client to perform foot and calf exercises every 2 hr
Correct Answer: C
Rationale: The correct answer is C because restricting flexion of the hip past 120° is crucial to prevent dislocation of the prosthetic hip joint post-operatively. Excessive flexion can lead to instability and potential complications. The other options are important but do not directly relate to the risk of hip dislocation. Administering enoxaparin helps prevent blood clots, using a wedge or pillow between the legs promotes proper alignment and comfort, and performing foot and calf exercises aids in preventing blood clots as well. However, restricting hip flexion is the most critical for the client's safety and optimal recovery after a total hip arthroplasty.

- A. Ciprofloxacin
- B. Doxycycline
- C. Amoxicillin
- D. Penicillin G
Correct Answer: D
Rationale: The correct answer is D, Penicillin G. Anthrax is caused by Bacillus anthracis, which is susceptible to ciprofloxacin and doxycycline. Penicillin and amoxicillin are not recommended due to the potential for B. anthracis to produce beta-lactamase, which can make the bacteria resistant to penicillin-based medications. Penicillin G is not effective in treating anthrax and should not be expected as a common treatment option.
