A nurse is caring for a patient with acute respiratory distress syndrome (ARDS) who is receiving mechanical ventilation using synchronized intermittent mandatory ventilation (SIMV). The settings include fraction of inspired oxygen (FIO2) of 80%, tidal volume of 450, rate of 16/minute, and positive end- expiratory pressure (PEEP) of 5 cm. Which assessment finding is most important for the nurse to report to the health care provider?
Respiratory rate 22 breaths/min
Heart rate 106 beats/min
02 saturation of 99%
Crackles audible at lung bases
The Correct Answer is D
D Crackles audible at the lung bases indicate the presence of pulmonary edema or fluid accumulation in the alveoli, which can compromise gas exchange and exacerbate respiratory distress. In a patient with ARDS, crackles suggest worsening pulmonary status and may indicate inadequate ventilation or oxygenation despite mechanical ventilation. Therefore, crackles at the lung bases are the most important finding to report to the healthcare provider as they may indicate a need for adjustments to the ventilator settings or additional interventions to optimize respiratory function and prevent further deterioration.
A respiratory rate of 22 breaths/min may be within an acceptable range, particularly considering that the patient is receiving mechanical ventilation. However, any significant deviation from the baseline respiratory rate or signs of respiratory distress, such as increased work of breathing or accessory muscle use, should be closely monitored and reported promptly.
B A heart rate of 106 beats/min may be within an acceptable range, although it is slightly elevated. Tachycardia can occur due to various factors, including pain, anxiety, fever, or hypoxemia. While tachycardia warrants close monitoring, it may not be the most critical finding to report unless it is associated with hemodynamic instability or other concerning symptoms.
C An oxygen saturation of 99% indicates adequate oxygenation, which is reassuring, particularly in a patient with acute respiratory distress syndrome (ARDS). However, oxygen saturation alone may not reflect the adequacy of ventilation or the severity of the underlying lung injury. Therefore, while oxygen saturation should be monitored closely, it may not be the most critical finding to report unless it declines significantly or is accompanied by other concerning symptoms.

Correct Answer is A
Explanation
A. Dobutamine is a positive inotropic agent that increases myocardial contractility, leading to improved cardiac output. Enhanced cardiac output can result in improved renal perfusion and increased urine output, which is a positive indicator of improved cardiac function in clients with heart failure.
B. Decreased blood glucose level is not typically associated with the effectiveness of dobutamine. Dobutamine primarily affects cardiac contractility and does not directly influence blood glucose levels.
C. Decreased blood pressure would not typically indicate the effectiveness of dobutamine. While dobutamine can increase cardiac output, it does not necessarily lead to a decrease in blood pressure.
D. Increased heart rate may occur as a compensatory mechanism in response to increased cardiac output due to dobutamine administration. However, increased heart rate alone may not reliably indicate the effectiveness of dobutamine.
Correct Answer is D
Explanation
D. Asystole represents the absence of electrical activity in the heart and is not amenable to defibrillation. Therefore, the RRT would continue cardiopulmonary resuscitation (CPR) with chest compressions and may administer medications or other interventions as indicated. This statement provides accurate information to the family about the patient's condition and the actions being taken by the RRT.
A. Defibrillation is not indicated for asystole. Asystole represents a flatline on the cardiac monitor, indicating the absence of electrical activity in the heart. Defibrillation is only effective for certain types of cardiac rhythms, such as ventricular fibrillation or pulseless ventricular tachycardia. Therefore, the RRT would not use defibrillation for a patient in asystole.
B. It does not provide the family with information about the patient's condition or the actions being taken by the RRT. Moreover, excluding the family from the patient's care may cause additional distress and prevent them from being present to support their loved one during a critical situation.
C. Cardiopulmonary resuscitation (CPR) is performed to maintain blood flow and oxygenation to vital organs during cardiac arrest. However, it does not restore normal blood flow or circulation. The goal of CPR is to provide temporary support until advanced interventions can be initiated or until return of spontaneous circulation (ROSC) is achieved.
