In a post-surgical unit, the nurse cares for many patients experiencing pain. Which situation is likely to lower a patient’s pain threshold?

Choice B rationale:

Phlebitis is the inflammation of a vein, often caused by an IV catheter. It's characterized by redness, swelling, warmth, and pain along the vein.

Promptly discontinuing the IV infusion is crucial to prevent further irritation and potential complications such as: Thrombophlebitis (inflammation with clot formation)

Infection

Infiltration (leakage of fluids into surrounding tissues) Extravasation (leakage of vesicant or damaging medications)

Continuing the infusion could exacerbate the inflammation and increase the risk of these complications.

Choice A rationale:

Elevation of the extremity can help reduce swelling, but it does not address the underlying inflammation. It's often used as an adjunct measure after discontinuing the IV.

Choice C rationale:

Warm, moist compresses can provide some comfort and potentially promote blood flow, but they are not recommended as a first-line treatment for phlebitis. They may even worsen inflammation in some cases.

Choice D rationale:

Inserting an IV catheter in the opposite extremity is necessary if the patient still requires IV therapy, but it should not be done before addressing the phlebitis in the current site. This could lead to multiple sites of inflammation and increased risk of complications.

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.
