Which of the following is an appropriate nursing intervention for a patient with a pulmonary artery catheter?

Assist with ambulation

Administer a diuretic medication

Administer a vasopressor medication

Monitor central venous pressure

Answer and Explanation

The Correct Answer is D

D. Monitoring central venous pressure (CVP) is an appropriate nursing intervention for a patient with a pulmonary artery catheter. While the pulmonary artery catheter primarily provides information about pulmonary artery pressures and cardiac output, it can also be used to measure central venous pressure. Monitoring CVP can help assess the patient's fluid status, right ventricular function, and response to fluid resuscitation. This intervention is directly relevant to the presence of the pulmonary artery catheter and helps guide patient management.

A. Assist with ambulation: It's not typically appropriate to assist a patient with ambulation while they have a pulmonary artery catheter in place. This catheter is inserted into the pulmonary artery and is used to monitor various hemodynamic parameters such as pulmonary artery pressure, cardiac output, and mixed venous oxygen saturation. Ambulation could disrupt the catheter placement or lead to complications such as bleeding or dislodgement.

B. Administering a diuretic medication may not be directly related to the presence of a pulmonary artery catheter. The use of diuretics is typically based on the patient's clinical condition and the healthcare provider's assessment of their fluid status and renal function. While information obtained from the pulmonary artery catheter, such as pulmonary artery pressure and cardiac output, may inform the decision-making process regarding diuretic therapy, the catheter itself does not dictate the administration of diuretics.

C. Administering a vasopressor medication may be appropriate for a patient with a pulmonary artery catheter if they are experiencing hypotension or shock. However, the decision to administer vasopressors should be based on the patient's hemodynamic parameters as assessed through the pulmonary artery catheter monitoring, along with clinical judgment and consideration of the underlying cause of the hypotension.

Correct Answer is B

Explanation

B. Endotracheal intubation and positive pressure ventilation are indicated in patients with respiratory failure who are unable to maintain adequate oxygenation or ventilation with non-invasive interventions. Intubation allows for the delivery of positive pressure ventilation, oxygenation, and airway protection. It also facilitates the clearance of secretions and administration of medications. Given the patient's severe hypoxemia, impending respiratory distress, and deteriorating condition, endotracheal intubation and positive pressure ventilation are the most appropriate interventions to ensure adequate oxygenation and prevent further deterioration.

A. CPAP is a non-invasive ventilation modality that provides a continuous positive pressure to the airways throughout the respiratory cycle. While CPAP may be beneficial in certain cases of respiratory failure, it may not be sufficient for a patient with severe hypoxemia (SpO2 of 80%) and impending respiratory distress. CPAP is typically indicated for patients with conditions such as obstructive sleep apnea or mild to moderate respiratory failure.

C. Mini-tracheostomy may be considered in certain cases of upper airway obstruction or inadequate airway clearance. However, in this scenario, the patient's hypoxemia is likely due to severe respiratory failure rather than upper airway obstruction. While suctioning may be necessary to clear secretions, it does not address the underlying cause of hypoxemia or provide ventilatory support.

D. While administration of supplemental oxygen is important in the management of hypoxemia, a non- rebreather mask may not be sufficient for a patient with severe hypoxemia and impending respiratory distress. Non-rebreather masks can deliver high concentrations of oxygen but may not provide adequate positive pressure support or airway protection. In this case, endotracheal intubation and positive pressure ventilation are more appropriate to ensure adequate oxygenation and ventilation.

A. The patient's IV infusion site is cool and pale. B. The patient's extremities are warm and dry. C. The patient's urine output is 28 ml, over the past hour. D. The patient's heart rate is 58 beats/min.

Correct Answer is A

Explanation

A. In a patient receiving a dobutamine infusion, which is a vasopressor medication used to increase cardiac output, a cool and pale IV infusion site could indicate inadequate perfusion despite treatment. This finding requires immediate action to assess the patient's hemodynamic status and ensure adequate tissue perfusion.

B. Warm and dry extremities are typically indicative of adequate tissue perfusion. In neurogenic shock, vasodilation can lead to warm extremities due to decreased systemic vascular resistance. While this finding may be expected in neurogenic shock, it does not necessarily indicate a need for immediate action if other parameters are stable.

C. Decreased urine output can be indicative of inadequate renal perfusion and impaired kidney function. In a patient with neurogenic shock, maintaining adequate renal perfusion is crucial to prevent acute kidney injury. While decreased urine output warrants close monitoring and intervention, it may not require immediate action unless other signs of worsening perfusion are present.

D. A heart rate of 58 beats/min may be within the normal range for some patients, especially those who are receiving dobutamine, which can have a chronotropic effect. However, in the context of neurogenic shock, bradycardia may indicate a compensatory response to hypotension and decreased tissue perfusion. While bradycardia alone may not always require immediate action, it should prompt further assessment of the patient's hemodynamic status and response to treatment.
