A nurse is collecting data from a client following removal of the client’s endotracheal tube. What findings should the nurse report to the provider?
Crackles
Stridor
Strong cough
Deep breathing
The Correct Answer is B
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.

Correct Answer is B
Explanation
Choice A rationale:
Metabolic alkalosis is characterized by a high pH (above 7.45), high bicarbonate (HCO3-) levels, and normal or low PaCO2. The patient's ABGs show a low pH (7.26), low bicarbonate (14 mEq/L), and low PaCO2 (30 mm Hg), which are not consistent with metabolic alkalosis.
Choice C rationale:
Respiratory alkalosis is characterized by a high pH (above 7.45), low PaCO2, and normal or slightly elevated bicarbonate levels. The patient's ABGs do show a low PaCO2, but the pH is low (acidic) and the bicarbonate is low, which are not consistent with respiratory alkalosis.
Choice D rationale:
Respiratory acidosis is characterized by a low pH (below 7.35), high PaCO2, and normal or slightly elevated bicarbonate levels. The patient's ABGs do show a low pH, but the PaCO2 is also low, which is not consistent with respiratory acidosis.
Rationale for the correct answer, B:
Metabolic acidosis is characterized by a low pH (below 7.35), low bicarbonate levels, and normal or low PaCO2. The patient's ABGs are consistent with metabolic acidosis because they show a low pH (7.26), low bicarbonate (14 mEq/L), and low PaCO2 (30 mm Hg).
Acute kidney injury is a common cause of metabolic acidosis. The kidneys play a vital role in regulating acid-base balance by excreting acids and reabsorbing bicarbonate. When the kidneys are damaged, they are unable to excrete acids effectively, leading to an accumulation of acids in the blood and a decrease in bicarbonate levels.
Additional Information:
It's important to note that the patient's low PaCO2 is likely a compensatory mechanism for the metabolic acidosis. In response to acidosis, the respiratory system tries to increase ventilation to blow off more carbon dioxide, which helps to raise the pH. However, this compensatory mechanism is often not enough to fully correct the acidosis.
Correct Answer is A
Explanation
The correct answer is Choice A.
Choice A rationale: Encouraging increased fluid intake helps maintain blood volume and reduces viscosity, promoting circulation and lowering the risk of venous stasis and clot formation postoperatively.
Choice B rationale: Keeping the affected knee flexed impairs venous return and increases stasis, elevating the risk of thrombosis. Proper positioning with extension promotes circulation and reduces clot risk.
Choice C rationale: Prolonged bed rest contributes to immobility-induced venous stasis, a major risk factor for DVT. Early ambulation and leg exercises are essential to prevent thromboembolic events.
Choice D rationale: Massaging the calf of a postoperative patient is contraindicated due to the risk of dislodging a thrombus, potentially leading to a life-threatening pulmonary embolism.
