A nurse is caring for a client who is being transferred from ER to ICU
The Correct Answer is []
In respiratory acidosis, there is an accumulation of carbon dioxide (CO2) in the blood due to inadequate ventilation, leading to an increase in the partial pressure of arterial carbon dioxide (PaCO2) and a decrease in pH.
This is often caused by conditions that impair ventilation, such as airway obstruction, respiratory muscle weakness, lung diseases (e.g., chronic obstructive pulmonary disease, pneumonia), or central nervous system depression (e.g., drug overdose, head injury).
Management of respiratory acidosis include bronchodilators, sodium bicarbonate, adequate ventilation, and treatment of underlying causes.

Correct Answer is B
Explanation
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 B
Explanation
B This maneuver, called the Valsalva maneuver, can sometimes help to restore normal heart rhythm in cases of SVT. It involves blowing forcefully into a syringe or performing a similar action that increases intra-abdominal pressure, which can stimulate the vagus nerve and help to slow down the heart rate.
A Defibrillation is a treatment used for life-threatening cardiac arrhythmias, particularly ventricular fibrillation or pulseless ventricular tachycardia. It involves delivering a therapeutic dose of electrical energy to the heart with a device called a defibrillator.
C Drawing troponin levels may be appropriate if there is suspicion of myocardial infarction as the cause of chest palpitations or if there are other symptoms suggestive of acute coronary syndrome. However, in the context of SVT presenting with chest palpitations and a racing heart, the priority is to address the arrhythmia first
D Amiodarone is an antiarrhythmic medication used to treat various types of cardiac arrhythmias, including ventricular and supraventricular arrhythmias. While it can be effective in certain cases of SVT, it is not typically the first-line treatment or the immediate next step in managing SVT in the emergency department.
