A toddler who has been hospitalized for vomiting due to gastroenteritis is sleeping and difficult to wake up. Assessment reveals: HR: 220 beats per minute (regular) Respiratory rate: 30 per minute BP: 84/52 Capillary refill: 3 seconds Which dysrhythmia does the nurse suspect in this child?
- A. Rapid pulmonary flutter
- B. Sinus bradycardia
- C. Rapid atrial fibrillation
- D. Supraventricular tachycardia (SVT)
