Mr Jones came to the ER complaining of chest palpitations. He states his heart feels like it is "racing". The nurse found the following rhythm on the monitor. What is the next step would the nurse expect to take first?
Defibrillate
Ask him to blow into a syringe
Draw troponins
Give amiodarone
The Correct Answer is B
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.

Correct Answer is ["B","C","D","E","F"]
Explanation
B. Continuous monitoring of vital signs, including blood pressure, heart rate, respiratory rate, and oxygen saturation, is essential for assessing the patient's hemodynamic status and response to treatment.
Additionally, continuous electrocardiographic (ECG) monitoring allows for real-time assessment of cardiac rhythm and conduction abnormalities.
C. This is an important nursing action to provide comfort and reduce anxiety for the patient. Transcutaneous pacing is often used as a temporary measure to stabilize heart rate and cardiac output until more definitive treatment, such as insertion of a permanent pacemaker, can be performed.
D. Atropine is another medication commonly used in ACLS protocols for symptomatic bradycardia and heart block. It acts to increase heart rate by blocking vagal tone. However, its effectiveness in third- degree heart block may be limited, and transcutaneous pacing is often the preferred intervention in this situation.
E. Correct placement of transcutaneous pacemaker pads is crucial for effective pacing. The pads should be placed on the chest over the heart to deliver electrical impulses and stimulate myocardial contraction. Proper placement ensures optimal pacing effectiveness and patient safety.
F. This nursing action addresses the patient's comfort and pain management following the placement of the transcutaneous pacemaker. The procedure may cause discomfort or pain, and appropriate analgesia should be provided to alleviate any discomfort and promote patient comfort.
A. Epinephrine is a medication commonly used in advanced cardiac life support (ACLS) protocols for bradycardia and heart block. In this scenario, the patient's heart rate has decreased to 40 beats/minute, indicating symptomatic bradycardia and potential hemodynamic instability. Epinephrine may be administered to increase heart rate and improve cardiac output.
Correct Answer is A
Explanation
A Adequate fluid administration is essential before giving vasopressors to patients with hypovolemic shock. The patient’s low central venous pressure indicates a need for more volume replacement. The other patient data are not contraindications to norepinephrine administration.
B Low dose dopamine is not a contraindication to epinephrine administration.
C A sinus tachycardia is not a contraindication to epinephrine administration
D Lack of urine output is not a contraindication to epinephrine administration
