A client is seeking information about the varicella vaccine (Varivax) What should the nurse inform the client about the vaccine?
Varivax is administered as a single dose during adulthood.
The vaccine is not effective in preventing shingles.
Varivax is a live attenuated vaccine.
The vaccine is recommended only for healthcare workers.
The Correct Answer is C
Choice A rationale:
Varivax is not administered as a single dose during adulthood. The vaccine is given as two doses, usually separated by 4 to 8 weeks, to ensure adequate protection.
Choice B rationale:
Varivax can reduce the risk of developing shingles, especially in individuals who had chickenpox and received the vaccine. While it may not completely prevent shingles, it can lessen its severity.
Choice C rationale:
This is the correct response. Varivax is a live attenuated vaccine, which means it contains weakened forms of the varicella-zoster virus that causes chickenpox. It stimulates the immune system to produce a protective response without causing the disease.
Choice D rationale:
Varivax is not recommended only for healthcare workers. It is recommended for certain groups, including children, adolescents, and adults who have not had chickenpox or received the vaccine. Healthcare workers might be among the targeted groups due to their increased risk of exposure, but it is not limited to them.

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:
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.
