A nurse is discussing the transmission cycle of VZV with a nursing student. Which statement by the student indicates a need for further education?
"Primary infection occurs when a person comes into contact with respiratory droplets.”
"Reactivation of VZV in the nerve cells leads to the onset of chickenpox.”
"The incubation period of VZV ranges from 10 to 21 days.”
"The risk of transmission is lower during reactivation compared to primary infection.”
The Correct Answer is B
Choice A rationale:
The primary infection of VZV occurs through respiratory droplets, not when a person comes into contact with them. The virus is highly contagious and spreads through respiratory secretions.
Choice B rationale:
Reactivation of VZV in the nerve cells leads to the onset of shingles, not chickenpox. Chickenpox is the primary infection, and after recovery, the virus remains dormant in nerve cells and can reactivate as shingles later in life.
Choice C rationale:
The incubation period of VZV for chickenpox ranges from 10 to 21 days, which is accurate information.
Choice D rationale:
The risk of transmission during reactivation (shingles) is higher than during primary infection (chickenpox) Shingles can cause the development of vesicles containing the virus, which can be contagious if someone comes into direct contact with the fluid from the vesicles. Primary chickenpox, on the other hand, spreads through respiratory droplets and is more widespread during the initial infection.

Correct Answer is D
Explanation
Choice A rationale:
Pregnant women should receive the Tdap vaccine during each pregnancy. This is a correct statement as vaccination during pregnancy helps provide protection to both the mother and the newborn against tetanus, diphtheria, and pertussis.
Choice B rationale:
The recommended vaccination schedule for adults includes a single dose of Tdap (tetanus, diphtheria, and acellular pertussis) vaccine, followed by a Td (tetanus and diphtheria) booster every 10 years. Three doses of DTP vaccine during adulthood are not part of the recommended schedule.
Choice C rationale:
Tetanus prophylaxis should be given to patients with all types of wounds, not just severe wounds. This statement is incorrect.
Choice D rationale:
The Tdap vaccine is not administered every 5 years during adulthood. As mentioned earlier, adults receive a single dose of Tdap and then a Td booster every 10 years.
Correct Answer is B
Explanation
Choice A rationale:
Administering the Td vaccine only if the wound is severe is not the correct response. Tetanus prophylaxis is recommended based on wound type and vaccination history, not just the severity of the wound.
Choice B rationale:
This is the correct response. Tetanus prophylaxis involves giving Tetanus Immunoglobulin (TIG) for immediate protection against tetanus toxin, along with the Tetanus and Diphtheria (Td) vaccine to promote long-term immunity. The decision to administer TIG and Td vaccine depends on the patient's wound type and their vaccination history.
Choice C rationale:
Tetanus prophylaxis is necessary even if the client received the DTP vaccine in childhood. The immunity from childhood vaccines may wane over time, and tetanus prophylaxis is recommended after potential exposure to the tetanus-causing bacteria.
Choice D rationale:
Giving the Td vaccine every 5 years is not the correct approach. The recommended schedule for Td booster doses is every 10 years, not every 5 years.
