Complete the diagram by dragging from the choices below to specify what condition the client is most likely experiencing, 2 actions the nurse should take to address that condition, and 2 parameters the nurse should monitor to assess the client's progress.

Answer and Explanation

The Correct Answer is []

AF is characterized by irregular, rapid heartbeat (100 to 175 beats per minute (bpm) and the absence of distinct P waves.

Management of unstable atrial fibrillation include immediate pharmacological or electrical cardioversion and anticoagulation.

Atrial fibrillation leads to ineffective pumping and stasis of blood in the heart which increases the risk of stroke.

On initiating anticoagulation, PTT/INR is important to ensure that the drug is administered at doses that achieve the optimal therapeutic effect.

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. Prone Position B. Positioning supine with head elevated to 30-45 degrees C. Infusion of Albumin D. Transfusion of PRBC

Correct Answer is A

Explanation

A. Prone positioning involves turning the patient onto their abdomen to improve ventilation-perfusion matching by redistributing ventilation to the dorsal lung regions, where perfusion is typically better in ARDS patients.

B. Semi-recumbent positioning may be used to prevent aspiration and reduce the risk of VAP but is not as effective as prone positioning for improving V/Q matching.

C. Albumin infusion is not specific interventions for improving ventilation-perfusion matching in ARDS and should be considered based on other clinical indications.

D. Transfusion of packed red blood cells (PRBC) may be indicated in cases of severe anemia or hypoxemia due to inadequate oxygen-carrying capacity. However, it is not a primary intervention for improving ventilation-perfusion matching in ARDS

A patient with respiratory failure has a respiratory rate of 26 breaths/min and an oxygen saturation (SpO2) of 80%. The patient is increasingly pale and restless but follows commands. Which intervention will the nurse anticipate?

Correct Answer is B

Explanation

A client with acute respiratory distress syndrome (ARDS) shows no improvement despite increases in concentration in oxygen administered. What intervention should the nurse attempt which may improve ventilation-perfusion matching?

Correct Answer is A

Explanation

Which information about a patient who is receiving cisatracurium (Nimbex) to prevent asynchronous breathing with the positive pressure ventilator requires action by the nurse?

A nurse is conducting a primary survey of a client who has sustained life-threatening injuries due to a motor-vehicle crash. Identify the sequence of actions the nurse should take. (Move the actions into the box on the right, placing them in the selected order of performance. Use all the steps.)

Which of the following factors can directly affect cardiac output?

An older patient with cardiogenic shock is cool and clammy. Hemodynamic monitoring indicates a high systemic vascular resistance (SVR). Which intervention should the nurse anticipate?

A nurse is suctioning the endotracheal tube of a client who is on a ventilator. The client's heart rate increases from 86/min to 110/min and becomes irregular. Which of the following actions should the nurse take?
