A client's telemetry monitor indicates ventricular fibrillation (VF). After delivering one counter shock, the nurse resumes chest compression. After another minute of compressions, the client's rhythm converts to supraventricular tachycardia (SVT) on the monitor. At this point, what is the priority intervention for the nurse?
- A. Prepare for transcutaneous pacing
- B. Deliver another defibrillator shock
- C. Administer IV Epinephrine per ACLS protocol
- D. Give IV dose of adenosine rapidly over 1-2 seconds
Correct Answer: D
Rationale: SVT can be treated by rapidly administering adenosine to restore normal sinus rhythm.

The school nurse has been following a child who frequently complains of dizziness and headache. Today, she is brought in after fainting in the cafeteria following a nosebleed. Her BP is 122/85, and her radial pulses are bounding. The nurse suspects she has:
- A. Transposition of the great vessels
- B. Coarctation of the aorta (COA)
- C. Aortic stenosis (AS)

While assessing a newborn with respiratory distress, the nurse auscultates a machine-like heart murmur. Other findings are a wide pulse pressure, periods of apnea, increased PaCO2, and decreased PO2. The nurse suspects that the newborn has:
- A. Pulmonary hypertension
- B. Patent ductus arteriosus (PDA)
- C. Ventricular septal defect (VSD)
- D. Bronchopulmonary dysplasia
Correct Answer: B
Rationale: A machine-like murmur is the hallmark of a PDA.
Hypoglycemia in an infant is defined as whole blood glucose level less than
