When admitting a patient with possible respiratory failure and a high PaCO2, which assessment information should be immediately reported to the health care provider?
The patient's blood pressure is 164/98.
The patient appears somnolent.
The patient's oxygen saturation is 90%.
The patient reports feeling weak.
The Correct Answer is B
B Somnolence, or excessive sleepiness, can indicate respiratory depression, hypercapnia (elevated PaCO2), or impending respiratory failure. Somnolence in this context is concerning as it may suggest worsening respiratory status and impending respiratory compromise. Therefore, it should be immediately reported to the healthcare provider for further evaluation and intervention.
A blood pressure of 164/98 mmHg is elevated but may not necessarily require immediate intervention, especially if the patient is not exhibiting signs of acute hypertensive crisis or end-organ damage.
However, it should be closely monitored and managed as appropriate. While hypertension may contribute to respiratory distress, it may not be the most critical finding to report immediately in a patient with possible respiratory failure and a high PaCO2.
C An oxygen saturation of 90% indicates hypoxemia, which can exacerbate respiratory failure and contribute to respiratory distress. While hypoxemia requires prompt intervention to improve oxygenation, it may not be the most critical finding to report immediately if the patient is not showing signs of severe respiratory distress or impending respiratory failure. However, it should be closely monitored and managed to prevent further deterioration.
D Weakness is a nonspecific symptom and may be related to various underlying causes, including respiratory failure, electrolyte imbalances, or systemic illness. While weakness warrants further assessment and management, it may not be the most urgent finding to report immediately in a patient with possible respiratory failure and a high PaCO2 unless it is accompanied by other concerning symptoms or signs of impending respiratory compromise.

Correct Answer is B
Explanation
B. Checking the left hand for pallor can help assess peripheral perfusion and determine if there is adequate blood flow distal to the arterial line insertion site. Pallor in the left hand could indicate decreased perfusion, which may contribute to the low-pressure alarm.
A. Re-zeroing the monitoring equipment may be necessary to ensure accurate pressure readings. However, it should not be the first action taken when the low-pressure alarm sounds. Before re-zeroing, the nurse should assess the patient's condition to ensure there are no immediate issues affecting arterial pressure.
C. Fast flushing the arterial line is not typically the first action to take when the low-pressure alarm sounds. Fast flushing may increase the risk of dislodging the catheter or causing air embolism if there is a problem with the line.
D. Assessing for dysrhythmias should be part of the overall assessment but may not be the first action taken in response to the alarm.
Correct Answer is B
Explanation
B. The QT interval represents ventricular depolarization and repolarization. It starts at the beginning of the QRS complex and ends at the end of the T wave. The QT interval reflects the total time it takes for both ventricular depolarization and repolarization to occur. Prolongation of the QT interval can be associated with an increased risk of arrhythmias, including torsades de pointes.
A. The QRS complex represents ventricular depolarization, which is the electrical activation of the ventricles. The duration of the QRS complex provides information about the time it takes for ventricular depolarization to occur. A prolonged QRS complex can indicate abnormalities in ventricular conduction, such as bundle branch blocks or ventricular hypertrophy.
C. The ST segment represents the early part of ventricular repolarization. It starts at the end of the QRS complex and ends at the beginning of the T wave. Changes in the ST segment, such as elevation or depression, can indicate myocardial ischemia or injury.
D. The PR interval represents the time it takes for the electrical impulse to travel from the atria to the ventricles. It includes atrial depolarization, atrial contraction, and the delay at the atrioventricular node. The PR interval does not specifically provide information about ventricular depolarization and repolarization.
