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
Explanation
B. This is advised to prevent hypoxemia, which can manifest as tachycardia and arrhythmia, conditions indicated by an increased and irregular heart rate. Pre-oxygenation helps maintain adequate oxygen levels in the blood, which can be compromised during the suctioning process.
A. Obtaining a cardiology consult might be necessary if the client's heart rate increases and becomes irregular. However, it's not the immediate action the nurse should take. This option is more appropriate for addressing the underlying cause of the client's dysrhythmia rather than the immediate management during suctioning.
C. Suctioning the client less frequently might be appropriate if the client's response to suctioning is causing distress or physiological changes like increased heart rate. However, if suctioning is necessary due to secretions in the airway, simply reducing the frequency might not be sufficient to address the client's cardiovascular response.
D. Administering an antidysrhythmic medication should be considered if the client's heart rate increases and becomes irregular during or after suctioning, especially if the dysrhythmia persists or worsens.
However, this should be done under the guidance of a healthcare provider and after assessing the client's overall condition, including potential causes of the dysrhythmia.
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
