A nurse is assisting in the care of a group of clients in the preoperative unit. Which of the following clients can give informed consent?

• Hoarseness: Mild hoarseness is a common temporary effect after thyroid surgery due to irritation or swelling near the recurrent laryngeal nerve. While it needs monitoring, slight hoarseness alone is not necessarily a sign of a serious complication if it is not worsening or associated with airway compromise.
• Drainage: A moderate amount of serosanguineous drainage from the incision site is expected after surgery. Although the drainage should continue to be monitored for increase or color change, the amount described here is not immediately concerning for a postoperative complication.
• Sensation: The client reports tingling in the fingers, which suggests hypocalcemia due to accidental removal or damage to the parathyroid glands during surgery. Hypocalcemia is a serious complication of thyroidectomy that can progress to muscle cramps, tetany, and seizures if untreated.
• Vital signs: The client’s rising temperature, tachycardia, hypertension, and increased respiratory rate are concerning for a developing thyroid storm, a rare but life-threatening complication after thyroid surgery. These vital signs warrant immediate intervention to prevent rapid deterioration.
• Pain assessment: A pain score of 3 out of 10 is mild and expected following surgery. This level of discomfort is manageable and not indicative of a major complication, provided it does not rapidly escalate or localize severely around the surgical site.

A. The restraint is attached to the side rails of the bed: Restraints should never be attached to the side rails because moving the rails could cause injury to the client. Restraints must be secured to a stationary part of the bed frame to prevent tightening, which could lead to impaired circulation or nerve damage if the bed position changes.

B. The restraint strap is tied into a knot: Tying the restraint strap into a knot is unsafe because knots are difficult to untie quickly in an emergency. Quick-release ties or slipknots are recommended to ensure the client can be released rapidly if needed, reducing the risk of injury or complications from prolonged restraint.

C. The nurse can insert two fingers under the restraint: Being able to insert two fingers under the restraint indicates that it is properly applied—not too tight to impair circulation, and not too loose to be ineffective. This ensures client safety by allowing adequate blood flow and reducing the risk of skin breakdown or nerve injury.

D. The skin under the restraint is cool and has changed color: Coolness and discoloration under a restraint are signs of impaired circulation and require immediate intervention. These findings are abnormal and suggest that the restraint is too tight, potentially leading to tissue ischemia, nerve damage, or pressure injuries if not promptly addressed.
