A charge nurse is conducting an in-service about smallpox with a group of nurses. Which of the following statements should the nurse include in the teaching?

"Smallpox lesions appear similar those of the varicella zoster virus”

"Smallpox is infectious prior to the development of the maculopapular rash”

"Healthcare workers should receive a yearly vaccination for smallpox “

"Smallpox is a current epidemic in third-world countries”

Answer and Explanation

The Correct Answer is B

A. "Smallpox lesions appear similar to those of the varicella zoster virus": Smallpox lesions are typically round, deep, and well-defined, whereas chickenpox lesions are more superficial and tend to appear in different stages simultaneously. The two are distinguishable.

B. "Smallpox is infectious prior to the development of the maculopapular rash": Smallpox is contagious during the incubation period and before the appearance of the rash, particularly during the early febrile phase when the virus is present in respiratory secretions.

C. "Healthcare workers should receive a yearly vaccination for smallpox": Routine vaccination for smallpox is no longer recommended for healthcare workers since smallpox was declared eradicated. The vaccine is typically administered to those at high risk of exposure in the event of an outbreak, but not annually.

D. "Smallpox is a current epidemic in third-world countries": Smallpox was declared eradicated in 1980 by the World Health Organization, and there are no current epidemics of smallpox in any country.

Correct Answer is B

Explanation

A. CPR: CPR is indicated if the client becomes pulseless or unresponsive, but it is not the first-line treatment for ventricular tachycardia (VT) if the client still has a pulse. In VT with a pulse, the priority is to treat the arrhythmia through defibrillation or medications, not CPR.

B. Defibrillation: Defibrillation is the most appropriate action for VT, especially if the client becomes pulseless or unstable. VT can deteriorate into ventricular fibrillation (VF), which is life-threatening. Immediate defibrillation is required to restore normal rhythm.

C. Radiofrequency catheter ablation: Radiofrequency catheter ablation is a long-term treatment option for VT, but it is not the immediate intervention for an acute episode. It is used to target and eliminate the arrhythmogenic focus after stabilization.

D. Elective cardioversion: Elective cardioversion is used for arrhythmias like atrial fibrillation or stable supraventricular tachycardias, not for life-threatening VT. In the case of VT with a pulse, if the client is unstable, defibrillation would be more appropriate.

A. Atrial Fibrillation (A-fib) B. Ventricular Fibrillation C. Ventricular Tachycardia D. Atrial Flutter (A-Flutter)

Correct Answer is B

Explanation

A. Atrial Fibrillation (A-fib): While Atrial Fibrillation is irregularly irregular and lacks discrete P waves, its QRS complexes are typically narrow and uniform, reflecting normal ventricular conduction. The QRS complexes in this strip are wide, bizarre, and highly irregular.

B. Ventricular Fibrillation: Ventricular fibrillation is characterized by rapid, chaotic electrical activity in the ventricles, resulting in no discernible P waves, QRS complexes, or T waves. The EKG appears as a disorganized, wavy line, indicating that the ventricles are merely quivering and not effectively pumping blood.

C. Ventricular Tachycardia: Ventricular tachycardia is typically a regular or slightly irregular rhythm with wide identifiable QRS complexes, and a rate usually between 100-250 bpm. While this rhythm is fast, it is completely chaotic and disorganized with no identifiable QRS complexes.

D. Atrial Flutter (A-Flutter): Atrial flutter is characterized by a "sawtooth" pattern of atrial activity (flutter waves) and typically a regular ventricular rhythm. This strip shows chaotic, disorganized ventricular activity, not organized flutter waves.
