A nurse is caring for a patient receiving IV therapy in the left forearm and notices that the site is red, swollen, and warm.
What action should the nurse take first?

Choice A rationale:

Respiratory acidosis is characterized by a low pH (less than 7.35), a high PaCO2 (greater than 45 mm Hg), and a normal or high HCO3 (22-26 mEq/L). It occurs when there is a buildup of carbon dioxide in the blood due to impaired ventilation.

The patient's ABGs do not align with respiratory acidosis because the pH is elevated (7.6), and the PaCO2 is within the normal range (40 mm Hg).

Choice B rationale:

Respiratory alkalosis is characterized by a high pH (greater than 7.45), a low PaCO2 (less than 35 mm Hg), and a normal or low HCO3 (22-26 mEq/L). It occurs when there is excessive loss of carbon dioxide through hyperventilation.

The patient's ABGs do not align with respiratory alkalosis because the HCO3 is elevated (32 mEq/L), which is not typical for this condition.

Choice C rationale:

Metabolic acidosis is characterized by a low pH (less than 7.35), a normal or low PaCO2 (less than 40 mm Hg), and a low HCO3 (less than 22 mEq/L). It occurs when there is an excess of acid in the body or a loss of bicarbonate.

The patient's ABGs do not align with metabolic acidosis because the pH is elevated (7.6), and the HCO3 is elevated (32 mEq/L).

Choice D rationale:

Metabolic alkalosis is characterized by a high pH (greater than 7.45), a normal or high PaCO2 (40-45 mm Hg), and an elevated HCO3 (greater than 26 mEq/L). It occurs when there is an excess of bicarbonate in the body or a loss of acid.

The patient's ABGs align with metabolic alkalosis because of the high pH (7.6), normal PaCO2 (40 mm Hg), and elevated HCO3 (32 mEq/L).

Rationale for Choice A:

Ineffective airway clearance is the most immediate and life-threatening concern in the postoperative period following a radical neck dissection. This procedure involves extensive removal of lymph nodes and tissues in the neck, which can significantly disrupt normal respiratory function and airway patency. Here's a detailed explanation of the factors contributing to this risk:

Altered Respiratory Anatomy: The surgical resection of tissues and lymph nodes can directly impact the structure and function of the airway. This includes potential narrowing of the trachea, vocal cord dysfunction, and impaired laryngeal movement, all of which can hinder effective airflow.

Thick, Copious Secretions: The surgical trauma and manipulation of tissues often lead to increased production of thick, tenacious secretions in the respiratory tract. These secretions can obstruct the airway, making it difficult for the patient to clear them effectively.

Impaired Cough Reflex: The surgical dissection may disrupt the nerves involved in the cough reflex, which is a crucial mechanism for clearing secretions from the airway. This further impedes the patient's ability to maintain a patent airway.

Risk of Aspiration: Accumulation of secretions in the airway elevates the risk of aspiration, which can lead to pneumonia and other serious complications.

Potential for Edema: Postoperative swelling in the neck tissues can further compress the airway, exacerbating the risk of obstruction.

Nursing Interventions for Ineffective Airway Clearance:

Prompt recognition and management of ineffective airway clearance are essential to prevent respiratory compromise and ensure patient safety. Here are key nursing interventions that should be prioritized:

Frequent Assessment: Continuously monitor respiratory rate, effort, breath sounds, oxygen saturation, and level of consciousness for any signs of respiratory distress.

Positioning: Elevate the head of the bed to 30-45 degrees to promote lung expansion and facilitate drainage of secretions. Suctioning: Regularly suction the airway to remove secretions, using aseptic technique and proper suctioning pressure.

Deep Breathing and Coughing Exercises: Encourage and assist the patient with deep breathing and coughing exercises to mobilize secretions.

Humidification: Provide humidified oxygen or use a nebulizer to help thin secretions and make them easier to expectorate.

Chest Physiotherapy: Perform chest physiotherapy techniques, such as percussion and vibration, to loosen secretions and promote their removal.

Monitoring Fluid Balance: Maintain adequate hydration to help thin secretions, while closely monitoring fluid intake and output to prevent fluid overload.

Addressing Other Choices:

While the other choices may also be relevant concerns in the postoperative period, they do not pose the same immediate threat to life as ineffective airway clearance.
