Question

Which finding is the best indication that a client with ineffective airway clearance needs suctioning? A. Oxygen saturation B. Respiratory rate C. Breath sounds D. Arterial blood gases

Short answer

Answer: Breath sounds.

Step-by-step solution

Oxygen Saturation

Oxygen saturation, or SpO2, is the percentage of oxygen-bound hemoglobin compared to the total amount of hemoglobin in the blood. While low oxygen saturation can indicate inadequate oxygenation due to airway obstruction, it can also be caused by other factors unrelated to the airway clearance. Therefore, solely relying on oxygen saturation may not be the best indicator for suctioning.

Respiratory Rate

The respiratory rate refers to the number of breaths taken per minute. An abnormal respiratory rate could indicate respiratory distress but cannot pinpoint the exact cause of the problem, nor can it determine whether suctioning is required.

Breath Sounds

Breath sounds are the noises produced by the respiratory system during breathing. Abnormal breath sounds, such as wheezing, crackling, or gurgling, can indicate the presence of mucus, secretions, or foreign bodies in the airway. These sounds can be heard through a stethoscope during a physical examination and can provide a more direct and specific indication for the need for suctioning.

Arterial Blood Gases

Arterial blood gas (ABG) test measures the levels of oxygen and carbon dioxide in the blood, along with other parameters like pH and bicarbonate levels. While the ABG test can provide an overall picture of a client's respiratory and metabolic status, it does not provide a direct indication of airway clearance or a need for suctioning. In addition, the test is invasive and not applicable as a routine assessment.

Conclusion

Among the given options, the best indication that a client with ineffective airway clearance needs suctioning is breath sounds (option C). Abnormal breath sounds provide a more direct and specific indication of airway obstruction, which is better suited to guide the decision for suctioning.

Key concepts

Airway Clearance

Airway clearance is a critical aspect of respiratory health, particularly for individuals with conditions that lead to an accumulation of mucus and secretions in the airways. Effective airway clearance is vital to maintain an open and clear pathway for air to move in and out of the lungs. It involves various techniques, including positioning, chest physiotherapy, and suctioning to remove obstructions, allowing the patient to breathe easier. Suctioning, which is often utilized in nursing, is a direct method to clear secretions when the patient cannot do so independently. Understanding the signs that indicate a need for suctioning, such as abnormal breath sounds or visible accumulation of secretions, is essential.When evaluating whether a patient requires airway clearance interventions like suctioning, healthcare providers perform assessments focusing on several indicators of respiratory function. These indicators help to differentiate between the need for immediate intervention and regular monitoring.

Suctioning in Nursing

Suctioning is a nursing intervention used to clear airway obstructions caused by accumulations of mucus, saliva, blood, or vomit. This procedure helps maintain a patent airway, promotes gas exchange, and prevents aspiration. It may be necessary in various settings, such as for patients with neuromuscular disorders, following surgery, or during severe illness when coughing is insufficient to clear secretions.

In the context of suctioning, ensuring that the procedure is carried out correctly is essential to prevent potential complications. These may include tissue trauma, hypoxia, or infection. As such, nurses must pay attention to the patient's breath sounds and oxygen saturation before, during, and after suctioning to assess its effectiveness and to determine the patient's tolerance to the procedure.

Breath Sounds Assessment

Breath sounds assessment is a key component of respiratory examination and provides invaluable information about the condition of a patient's airways and lungs. The sounds heard can include normal breath sounds and adventitious or abnormal sounds such as wheezing, crackles, or stridor. These abnormal sounds often represent the presence of secretions, fluid, or foreign objects that are impeding the passage of air. Nurses use a stethoscope to listen to these sounds at various points on the chest and back. The findings from a breath sounds assessment can help nurses to determine the immediacy and type of intervention required, such as suctioning, to improve a patient's airway clearance.

Oxygen Saturation

Oxygen saturation, typically measured with a pulse oximeter, is a non-invasive way to monitor the amount of oxygen carried by hemoglobin in the blood. The normal range for a healthy individual is typically between 95% and 100%. A reading below this range can suggest hypoxemia, which may result from respiratory conditions, circulatory issues, or an inability to effectively clear the airway. While a low oxygen saturation indicates that a patient may be experiencing respiratory compromise, it does not specifically identify airway blockages, so it should be considered alongside other clinical signs such as breath sounds, respiratory rate, and responsiveness to treatments like suctioning.

Respiratory Rate

Respiratory rate is the count of breaths taken per minute and is a vital sign that can indicate the general state of respiratory health. Normal rates typically range from 12 to 20 breaths per minute for a resting adult. Deviations from this range, either tachypnea (increased rate) or bradypnea (decreased rate), can signal distress or dysfunction within the respiratory system. Tachypnea, for example, might suggest an effort to increase oxygen uptake or to compensate for a partially obstructed airway. While important to note, the respiratory rate alone cannot confirm the need for airway clearance interventions, such as suctioning, without additional assessment data.

Arterial Blood Gases

Arterial blood gases (ABGs) are a series of tests performed on blood taken from an artery. They measure oxygen and carbon dioxide levels, pH balance, and other parameters like bicarbonate. These measurements provide insight into respiratory efficacy and metabolic processes. ABGs can help diagnose and monitor conditions like chronic obstructive pulmonary disease (COPD), asthma, and respiratory failure. Although ABGs offer a detailed picture of a patient's ventilatory status, they are an invasive procedure and not typically used for routine assessments of airway clearance. Due to the complexity and invasiveness, ABGs are generally reserved for critically ill patients or those with severe alterations in respiratory function.
