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 B
Explanation
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 C
Explanation
C. its use in hypovolemic shock is generally not appropriate because the primary treatment for hypovolemic shock is fluid resuscitation to address the volume loss.
A. Dopamine is often used in neurogenic shock to increase systemic vascular resistance and improve blood pressure. Therefore, dopamine is an appropriate choice for the management of hypotension due to neurogenic shock.
B. Dopamine is commonly used in septic shock to improve cardiac output and systemic vascular resistance. It helps to support blood pressure and perfusion in septic shock patients.
D. It is indicated for cardiogenic shock as it increases cardiac contractility.
