A client experiencing withdrawal from the benzodiazepine alprazolam is demonstrating severe agitation and tremors. Which is the best initial nursing action?

Semi Fowler's position:

- This position involves raising the head of the bed to an angle of 30 to 45 degrees. It is

commonly used to improve respiratory function and comfort in patients who are experiencing

difficulty breathing. By elevating the head and torso, this position facilitates better lung expansion, helping to improve oxygenation.

Promote lung expansion:

- In patients with respiratory issues such as pneumonia, positioning that enhances lung expansion is critical. Semi Fowler's position helps to reduce pressure on the diaphragm, allowing for more effective lung expansion and improved oxygenation. This is particularly important for a patient with decreased breath sounds and consolidation in the lungs, as it aids in alleviating respiratory distress and improving gas exchange.

A. Increase the fractional concentration of Inspired oxygen: As the partial pressure of oxygen (PaO) has decreased to 64 mm Hg from 99 mm Hg, and the oxygen saturation may drop, it's necessary to increase the fraction of inspired oxygen (FiO2) to maintain adequate oxygenation.
B. Change the ventilator settings to continuous positive airway pressure (CPAP): CPAP is not typically used in patients who are intubated. CPAP is a non-invasive ventilation mode used for patients with respiratory distress who are breathing spontaneously. In this case, the patient is intubated and requires mechanical ventilation, so CPAP is not appropriate.
C. Increase the respiratory rate: While the respiratory rate has decreased from 15 to 13 breaths/minute, it's important to maintain a careful balance when adjusting ventilator settings. Increasing the respiratory rate may not be necessary at this point, especially if the patient is still oxygenating adequately. Moreover, the primary concern appears to be hypoxemia rather than hypoventilation.
D. Continue weaning the ventilator as ordered: While weaning the patient off the ventilator is a goal, it may not be appropriate at this time, especially with the worsening blood gas values
indicating respiratory insufficiency. Continuing the weaning process could potentially exacerbate respiratory failure.

E. Decrease the tidal volume: Decreasing the tidal volume could worsen ventilation-perfusion matching and exacerbate hypoxemia. This approach might be considered in certain cases of acute respiratory distress syndrome (ARDS) or in patients with severe lung injury, but it's not typically indicated in this scenario without further assessment.

F. Alert the provider of the blood gas values: The nurse should inform the provider about the changes in blood gas values, especially the decrease in PaO2 and the increase in PaCO2, which indicate worsening respiratory status and potential respiratory acidosis.

G. Switch the ventilator to pressure control: Given the deterioration in respiratory status with an increase in PaCO2 and decrease in PaO2, switching to pressure control ventilation may provide better control over the patient's ventilation and oxygenation, especially in cases of acute
respiratory failure.
