In Wolff-Parkinson-White syndrome:
- A. The abnormal pathway is between the atrial and ventricular myocardium
- B. Wide QRS complexes occur more frequently than narrow QRS
- C. Narrow QRS complexes are regular
- D. Verapamil is the treatment of choice for atrial fibrillation
Correct Answer: B
Rationale: In Wolff-Parkinson-White syndrome, a wide QRS complex is often seen due to the presence of an accessory pathway that bypasses the normal conduction system.

A nurse is teaching nursing students the physiology of congenital heart defects. Which defect results in decreased pulmonary blood flow?
- A. Atrial septal defect
- B. Tetralogy of Fallot
- C. Ventricular septal defect
- D. Patent ductus arteriosus
Correct Answer: B
Rationale: Tetralogy of Fallot results in decreased blood flow to the lungs. The pulmonic stenosis increases the pressure in the right ventricle, causing the blood to go from right to left across the ventricular septal defect. Atrial and ventricular septal defects and patent ductus arteriosus result in increased pulmonary blood flow.
In truncus arteriosus, all the following are true EXCEPT
- A. VSD is always present
- B. clinical manifestations are characterized by severe cyanosis and the degree of cyanosis are high
- C. both ventricles fail clinically
- D. cyanosis is usually mild
Correct Answer: B
Rationale: Cyanosis is usually mild initially in truncus arteriosus.
The nurse is assessing a client who has tinea pedis. Which question will allow the nurse to gather further information about this condition?
- A. Do you see any improvement when using tolnaftate?
- B. Have you been avoiding wearing tight-fitting shoes?
- C. Are you experiencing pain or itching in your feet?
- D. How often do you wash your feet and change socks?

Xanthomas within palmar creases are seen characteristically in
- A. Pseudoxanthoma elasticum
- B. Type II hyperlipoproteinemia
- C. Type IIl hyperlipoproteinemia
- D. Hypothyroidism
Correct Answer: C
Rationale: Xanthomas within palmar creases are characteristic of Type III hyperlipoproteinemia.
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.
