A nurse is caring for a group of patients on an adult medical-surgical unit.
Which patient should the nurse identify as having the highest risk for aspiration?

Choice A rationale:

A colostomy is a surgical procedure that creates an opening in the colon (large intestine) to divert stool through the abdomen. While a colostomy can affect bowel function, it does not directly increase the risk of aspiration. This is because the colon is located further down the digestive tract and does not directly involve the airway.

Choice B rationale:

An ileostomy is a surgical procedure that creates an opening in the ileum (small intestine) to divert stool through the abdomen. Similar to a colostomy, an ileostomy does not directly increase the risk of aspiration because the ileum is also located further down the digestive tract and does not involve the airway.

Choice C rationale:

Enteral feedings, also known as tube feedings, involve delivering nutrients directly into the stomach or small intestine through a tube. Patients receiving enteral feedings through a nasogastric (NG) tube are at a significantly higher risk of aspiration for several reasons:

Impaired swallowing mechanisms: Many patients who require enteral feedings have impaired swallowing mechanisms, which can increase the risk of food or liquid entering the airway instead of the esophagus.

Tube placement: The NG tube itself can potentially irritate the esophagus or interfere with the normal closure of the upper esophageal sphincter, which can increase the risk of reflux and aspiration.

Feeding formula: Enteral feeding formulas are often thin and liquid-like, which can make them easier to aspirate than thicker liquids or solid foods.

Positioning: Patients receiving enteral feedings are often in a reclined position, which can make it easier for fluids to travel back up the esophagus and into the airway.

Choice D rationale:

A chest tube is a drainage tube inserted into the chest cavity to remove air or fluid. While a chest tube can affect respiratory function, it does not directly increase the risk of aspiration. This is because the chest tube drains fluid from the pleural space, which surrounds the lungs, and does not directly involve the airway or digestive tract.

Choice B rationale:

Stridor is a high-pitched, whistling sound that is heard during inspiration. It is a sign of upper airway obstruction, indicating a potentially life-threatening complication that requires immediate intervention.

Here's a detailed explanation of why stridor is the most concerning finding and why the other choices are not as indicative of a serious problem:

Stridor:

Mechanism: Stridor occurs when there is narrowing or obstruction of the upper airway, typically at the level of the larynx or trachea. This narrowing can be caused by various factors, including:

Laryngospasm: A sudden constriction of the vocal cords, often triggered by irritation or inflammation. Post-extubation edema: Swelling of the tissues in the airway after removal of the endotracheal tube.

Mucus plugging: Accumulation of thick secretions in the airway, which can partially block airflow.

Vocal cord dysfunction: Impairment of the vocal cords' movement, which can affect their ability to open and close properly.

Significance: Stridor is a serious sign because it indicates that airflow is significantly restricted. If left untreated, upper airway obstruction can lead to hypoxia (low oxygen levels) and respiratory failure.

Nursing intervention: If stridor is present, the nurse should immediately notify the provider and prepare for potential interventions to secure the airway, such as:

Reintubation: Reinserting the endotracheal tube to bypass the obstruction.

Nebulized racemic epinephrine: Medication to reduce swelling in the airway.

Heliox: A mixture of helium and oxygen that can improve airflow through a narrowed airway. Steroids: Medications to reduce inflammation in the airway.

Crackles (Choice A):

Description: Crackles are rattling, crackling sounds heard in the lungs, often during inspiration. They are typically associated with lower airway problems, such as pneumonia or pulmonary edema.

Significance: While crackles can indicate respiratory issues, they are not as immediately concerning as stridor in the context of post-extubation care.

Strong cough (Choice C):

Significance: A strong cough is generally a positive sign after extubation, as it indicates that the patient is able to clear secretions from their airway effectively.

Deep breathing (Choice D):

Significance: Deep breathing is also a positive sign, as it promotes lung expansion and oxygenation.
