The nurse is reviewing the chart of a client who has a traumatic below-the-knee amputation. Which client should the nurse see first?
- A. Female client who had an arthroscopic rotator cuff repair with sling immobilization and reports moderate swelling and tingling of the hand and fingers
- B. Female client who has a new cast and reports stinging of the hand and fingers and inability to move the toes
- C. Male client who has two new prosthetic legs applied after traumatic below-the-knee amputation and reports crushing pain in the amputated areas
- D. Male client who has a hematocrit of 37% (0.37) and hemoglobin of 12.5 g/dL (125 g/L) and is prescribed enoxaparin 1 day after a total hip arthroplasty
Correct Answer: A
Rationale: Stinging and inability to move toes in a new cast suggest compartment syndrome, a surgical emergency. Phantom limb pain and normal hematocrit/enoxaparin are less urgent.

- B. Apply an occlusive dressing over the insertion site
- C. Assist the client to high Fowler position
- D. Monitor vital signs and respiratory effort

The nurse is assessing a client who had a thyroidectomy 12 hours ago and is reporting anxiety, tingling around the mouth, and muscle twitching in the hand. Which of the following actions would be a priority for the nurse to take?
- A. Check the area around the incision site for edema
- B. Review the client’s most recent arterial blood gas results
- C. Evaluate the client’s vocal quality and strength
- D. Obtain a blood specimen to check the serum calcium level
Correct Answer: D
Rationale: Anxiety, tingling, and twitching suggest hypocalcemia from parathyroid damage during thyroidectomy, requiring urgent calcium level assessment. Edema, blood gases, and vocal quality are less urgent.
