A nurse is monitoring a patient's temperature after surgery. The patient has a fever of 38.5°C (101.3°F) and chills. What is the most likely cause of the fever?

Choice A reason:

Tingling in the fingers and toes is a sign of paresthesia, which is a common symptom of hypocalcemia. Hypocalcemia occurs when the blood calcium level is too low, which can happen after a thyroidectomy if the parathyroid glands are damaged or removed. The parathyroid glands produce parathyroid hormone, which regulates calcium balance in the body. Without enough parathyroid hormone, calcium levels drop and cause neuromuscular irritability and numbness or tingling sensations.

Choice B reason:

Difficulty swallowing and speaking is not a specific sign of hypocalcemia, but rather a possible complication of a thyroidectomy due to injury to the recurrent laryngeal nerve. This nerve innervates the muscles of the larynx, which control voice production and swallowing. Damage to this nerve can cause hoarseness, weak voice, or vocal cord paralysis.

Choice C reason:

Dry mouth and increased thirst are not signs of hypocalcemia, but rather signs of dehydration. Dehydration can occur for various reasons, such as fluid loss, inadequate fluid intake, or increased fluid needs. Dehydration can affect the electrolyte balance in the body, but it does not directly cause hypocalcemia.

Choice D reason:

Muscle weakness and fatigue are not specific signs of hypocalcemia, but rather general signs of malaise. Malaise can occur for various reasons, such as infection, inflammation, stress, or chronic illness. Malaise can affect the physical and mental well-being of a person, but it does not directly cause hypocalcemia.

Choice A reason:

This is a correct statement by the client. Using a pillow between the legs when sleeping helps to maintain the hip in abduction and prevent dislocation of the prosthesis.

Choice B reason:

This is also a correct statement by the client. Avoiding crossing the legs or bending forward prevents excessive flexion of the hip and reduces the risk of dislocation.

Choice C reason:

This is another correct statement by the client. Reporting any signs of infection or bleeding to the doctor is important to prevent complications such as wound infection, hematoma, or sepsis.

Choice D reason:

This is an incorrect statement by the client that indicates a need for further teaching. Resuming normal activities as soon as the client feels better is not advisable, as it may cause excessive stress on the joint and lead to loosening or fracture of the prosthesis. The client should follow a gradual rehabilitation program and avoid activities that involve high impact, twisting, or lifting.

Choice E reason:

This is also an incorrect statement by the client that indicates a need for further teaching. Taking anticoagulant medication as prescribed is not enough to prevent thromboembolic events after a total hip replacement. The client should also wear compression stockings, use intermittent pneumatic compression devices, and perform ankle and foot exercises as instructed. The client should also monitor for signs of bleeding or bruising and report any abnormal findings to the doctor.
