Exhibits
Based on the client's status at 1400, the nurse should plan to do which of the following? Select all that apply.
Increase the fractional concentration of Inspired oxygen
Change the ventilator settings to continuous positive airway pressure (CPAP)
Increase the respiratory rate
Continue weaning the ventilator as ordered
Decrease the tidal volume
Alert the provider of the blood gas values
Switch the ventilator to pressure control
Correct Answer : A,F,G
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.

Correct Answer is D
Explanation
A. Verify the prothrombin time (PT).
While it is important to verify coagulation status in patients with atrial fibrillation to ensure they are not at high risk for bleeding, this is not the most critical step immediately prior to
cardioversion. The PT is more relevant if anticoagulation therapy is being managed.
B. Administer prescribed sedative.
Administering a sedative is important for patient comfort during the procedure, but it is not the most critical step that directly affects the success and safety of the cardioversion itself.
C. Select a monitor lead with a tall R wave.
Selecting a monitor lead with a tall R wave helps in accurately synchronizing the cardioversion shock with the R wave, but this is secondary to activating the synchronization mode which is critical to avoid delivering a shock during the vulnerable period of the cardiac cycle.
D. Activate the synchronization mode.
This is the correct answer. The most important action before deploying the current for cardioversion is to ensure the defibrillator is in synchronization mode. Synchronization ensures that the electrical shock is delivered at the correct time during the cardiac cycle, specifically on the R wave of the QRS complex, to avoid inducing ventricular fibrillation. This is crucial for
patient safety.
Correct Answer is A,B,C,D
Explanation
A. Elevate the head of the bed. This intervention is the highest priority to prevent aspiration and improve the client's comfort and breathing.
B. Complete focused assessment. A thorough assessment is necessary to gather more information about the client's condition and guide further interventions.
C. Send emesis sample to the lab. This helps in diagnosing the underlying cause of the dark brown emesis, which could indicate a serious gastrointestinal issue.
D. Offer PRN pain medication. Pain management is important but should be done after addressing immediate safety concerns and gathering sufficient assessment data.
