(ATI/HESI MCQ) Which laboratory test is useful in confirming the diagnosis of chickenpox?

Choice A rationale:

Anemia is not a complication typically associated with shingles. Shingles is caused by the varicella-zoster virus, and it primarily affects the nerves and skin, leading to a painful rash.

Choice B rationale:

Migraine headaches are not directly related to shingles. Shingles affects sensory nerves and typically presents with localized pain and a rash along the affected nerve's pathway.

Choice C rationale:

The nurse should monitor for postherpetic neuralgia in this client. Postherpetic neuralgia is a common complication of shingles that involves persistent and severe pain in the area where the rash was present. It occurs due to nerve damage caused by the virus, and the pain can last for weeks to months after the rash has healed.

Choice D rationale:

Asthma is not a complication associated with shingles. Shingles is a viral infection that primarily affects the skin and nerves and does not involve the respiratory system.

Choice A rationale:

(Incorrect) Shingles, caused by the varicella-zoster virus, can be transmitted through direct contact with the fluid from the vesicles (blisters) of a person who has active shingles. However, it is important for the nurse to provide correct information to the client.

Choice B rationale:

(Correct) Shingles can only occur in individuals who have previously had chickenpox. After a person recovers from chickenpox, the virus remains dormant in the nerve tissues. Later in life, the virus can reactivate, leading to shingles. It is crucial for the nurse to emphasize this point to prevent any misunderstandings.

Choice C rationale:

(Incorrect) While the shingles vaccine is effective in reducing the risk of developing shingles, it does not have a 100% efficacy rate. The vaccine can, however, reduce the severity and duration of the illness if shingles still occur after vaccination.

Choice D rationale:

(Incorrect) The herpes zoster vaccine (shingles vaccine) is not given to children under 10 years old. It is recommended for adults aged 50 years and older or for individuals with certain risk factors.
