Which assessment information obtained by the nurse when caring for a COPD patient receiving mechanical ventilation indicates the need for suctioning?
The pulse oximeter shows a Sp02 of 90%.
The patient has not been suctioned for the last 6 hours.
The respiratory rate is 32 breaths/min.
The lungs have occasional audible expiratory wheezes.
The Correct Answer is C
In a patient receiving mechanical ventilation, a high respiratory rate can indicate increased work of breathing and potential airway obstruction. COPD patients, in particular, may have excessive mucus production and airway inflammation, leading to mucus plugging and compromised airway clearance. Suctioning may be necessary to remove excessive secretions and maintain a patent airway.
A. The pulse oximeter shows a SpO2 of 90% in (option A) is incorrect because While a SpO2 of 90% is suboptimal and may require intervention, it does not specifically indicate the need for suctioning. Other interventions, such as adjusting oxygen delivery or ventilation settings, may be more appropriate.
B. The patient has not been suctioned for the last 6 hours in (option B) is incorrect because The duration since the last suctioning episode alone does not necessarily indicate the need for suctioning. The need for suctioning should be based on the patient's clinical presentation, such as signs of airway obstruction or excessive secretions.
D. The lungs have occasional audible expiratory wheezes in (option D) which is incorrect because Occasional audible expiratory wheezes may be common in patients with COPD and may not specifically indicate the need for suctioning. Wheezing is more commonly associated with narrowing of the airways, and suctioning is typically performed to clear secretions or maintain airway patency.
C. Therefore, in a COPD patient receiving mechanical ventilation, a high respiratory rate (C) is the assessment information that would indicate the need for suctioning to help remove excessive secretions and ensure a patent airway

Correct Answer is A
Explanation
The QTc (corrected QT) interval is a measure of the time it takes for the ventricles to depolarize and repolarize during a cardiac cycle. It is corrected for heart rate (HR) to account for variations in the cardiac cycle length.
The normal range for the QTc interval varies depending on the calculation method used but generally falls within 0.36 to 0.44 seconds. In the given options, the range of 0.33 to 0.47 seconds for the QTc interval is wider than the normal range, suggesting a prolonged QTc interval, which can be indicative of a potential risk for arrhythmias, including ventricular tachycardia and torsades de pointes.
B. QT interval that varies with HR in (option B) is normal because The QT interval alone can vary with heart rate, and this is considered a normal physiological adaptation.
C. QRS interval <0.12 seconds in (option C) is normal because The QRS interval represents the time it takes for ventricular depolarization and is normally less than 0.12 seconds.
D. PR interval 0.12 to 0.24 seconds in (option D) is normal because The PR interval represents the time it takes for atrial depolarization and conduction through the AV node. The normal range is typically 0.12 to 0.20 seconds.
Correct Answer is B
Explanation
Cool, clammy skin, tachycardia, and hypotension are signs of shock, indicating inadequate tissue perfusion and oxygenation. The immediate priority is to ensure adequate oxygen delivery to the tissues. Providing oxygen at 100% via a non-rebreather mask helps increase the patient's oxygen saturation and improve tissue oxygenation.
While all the options mentioned are important in the management of a patient in shock, oxygenation takes priority as it directly addresses compromised tissue perfusion and oxygenation.
A. Inserting two large-bore IV catheters in (option A) is incorrect because: Establishing intravenous access is crucial for fluid resuscitation and administration of medications, but it can be done after ensuring adequate oxygenation.
C. Drawing blood to type and crossmatch for transfusions in (option C) is incorrect because Blood typing and crossmatching are important for potential blood transfusions but should not be the first action in this critical situation.
D. Initiating continuous electrocardiogram (ECG) monitoring in (option D) is incorrect because Continuous ECG monitoring is important for assessing cardiac rhythm and detecting any dysrhythmias, but ensuring oxygenation should be the initial priority.
Therefore, in a patient presenting with cool, clammy skin, tachycardia, and hypotension, the nurse should first provide oxygen at 100% via a non-rebreather mask to address inadequate tissue perfusion and oxygenation.
