The nurse is caring for a client with a history of heart failure and notes a new onset of the following rhythm on the client's telemetry monitor. Which action would the nurse take first?

Administer the prescribed daily dose of metoprolol

Obtain the client's blood pressure and pulse

Notify the health care provider about the rhythm

Print a rhythm strip to document the changes in the health record

Answer and Explanation

The Correct Answer is B

B. Assessing the client's vital signs, including blood pressure and pulse, provides critical information about the client's hemodynamic status and response to the new rhythm. Atrial fibrillation can lead to rapid, irregular heart rates and hemodynamic instability, so obtaining vital signs promptly helps the nurse determine the severity of the situation and whether immediate intervention is needed.

A. This action is not the priority when the nurse observes a new onset of atrial fibrillation. While beta- blockers such as metoprolol may be part of the client's long-term management for heart failure and atrial fibrillation, initiating medication administration without further assessment could delay appropriate intervention for the acute change in rhythm.

C. While it is important to communicate changes in the client's condition to the healthcare provider, this action should occur after the nurse has assessed the client's vital signs and determined the urgency of the situation. If the client is stable and responsive to initial interventions, the nurse can then contact the healthcare provider to discuss the new onset of atrial fibrillation and collaborate on further management.

D. Documenting the changes in the client's rhythm is important for continuity of care and communication among healthcare team members. However, obtaining a rhythm strip should not be the first action when a new onset of atrial fibrillation is observed. Assessing the client's vital signs and initiating appropriate interventions to address any hemodynamic instability take precedence.

Correct Answer is C

Explanation

C. Hypovolemia, or low blood volume, can lead to decreased venous return to the heart and reduced filling pressures. Consequently, CVP may decrease in hypovolemic states. Low CVP may indicate inadequate preload and reduced cardiac output, which are characteristic of hypovolemia.

A. Left ventricular failure typically results in elevated filling pressures rather than low CVP. In left ventricular failure, blood backs up into the pulmonary circulation, leading to increased pulmonary venous pressure and potentially elevated pulmonary capillary wedge pressure (PCWP), which is a surrogate marker for left atrial pressure. This elevated pressure is reflected in the CVP as well, resulting in increased CVP rather than low CVP.

B. Fluid overload typically results in elevated filling pressures and increased CVP rather than low CVP. Excess fluid volume increases venous return to the heart, leading to increased pressure within the central veins and elevated CVP.

D. Intracardiac shunts may cause alterations in cardiac pressures, but they typically do not result in consistently low CVP. Depending on the type and severity of the shunt, the direction and magnitude of pressure changes may vary. However, in the absence of other pathophysiological factors, intracardiac shunts are less likely to cause consistently low CVP.

A. Apply restraints if the client becomes agitated. B. Verify the prescribed ventilator settings daily. C. Reposition the endotracheal tube to the opposite side of the mouth daily. D. Administer pantoprazole as prescribed. E. Elevate the head of the bed to at least 30".

Correct Answer is ["B","D","E"]

Explanation

B. This is an essential nursing intervention to ensure that the ventilator is delivering the appropriate settings as ordered by the healthcare provider. Ventilator settings may need to be adjusted based on the client's condition, so daily verification is important for patient safety and optimal ventilator management.

D. Pantoprazole is a proton pump inhibitor commonly used to prevent stress ulcers in critically ill patients receiving mechanical ventilation. It helps reduce gastric acid secretion and can prevent complications such as gastrointestinal bleeding. Administering pantoprazole as prescribed is an appropriate intervention to prevent complications related to stress ulcers in ventilated patients.

E. Elevating the head of the bed to at least 30 degrees is a crucial intervention to prevent ventilator- associated pneumonia (VAP) by reducing the risk of aspiration. This position helps promote drainage of oral and gastric secretions, reducing the likelihood of aspiration into the lungs. It's considered a standard practice in ventilated patients to minimize the risk of pulmonary complications.

A. Apply restraints if the client becomes agitated: While it may be necessary to use restraints in certain situations to ensure the safety of the client and prevent self-extubation or injury, they should be used judiciously and only when other measures to manage agitation have failed. Restraints should not be the first-line intervention and should be used in accordance with facility policies and regulations.

C. Repositioning the endotracheal tube to the opposite side of the mouth daily is not a standard nursing intervention. Once the endotracheal tube is properly positioned and secured, it should not routinely need to be repositioned unless clinically indicated due to complications such as mucosal irritation or tube displacement.
