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”
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. Prepare to administer Albuterol to aid the patient's breathing: Albuterol is used for bronchodilation in asthma or COPD. The priority is addressing the potential life-threatening condition, such as a pneumothorax or hemothorax, indicated by the patient's tracheal deviation and labored breathing.
B. Prepare for chest tube insertion: The tracheal deviation, falling blood pressure, and labored breathing suggest a possible tension pneumothorax or hemothorax, both of which require immediate chest tube insertion. This is necessary to relieve pressure in the chest and allow the lungs to re-expand, addressing the respiratory and circulatory distress.
C. Prepare to apply oxygen via non-rebreather mask at 8L/Min: While oxygen is necessary, simply applying oxygen will not resolve the underlying mechanical issue of a tension pneumothorax. The pressure in the chest needs to be relieved for the lung to re-expand and effectively take up oxygen.
D. Sit the patient up in high-fowler's position: While sitting the patient up may help with breathing in some conditions, the most likely cause of the patient’s symptoms is a traumatic injury that requires chest tube insertion, not just positioning.
Correct Answer is ["0.8"]
Explanation
Desired dose = 3,800 units.
Available concentration = 5,000 units/mL.
- Calculate the volume to administer.
Volume (mL) = Desired dose (units) / Available concentration (units/mL)
= 3,800 units / 5,000 units/mL
= 0.76 mL.
- Round the answer to the nearest tenth.
= 0.8 mL.
