(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:

Encouraging using sterile instruments for cutting umbilical cords is important in preventing tetanus as contaminated instruments can introduce the

C. tetani spores, leading to infection.

Choice B rationale:

Promoting safe delivery practices in clean facilities is crucial to prevent tetanus in newborns. Clean delivery facilities reduce the risk of exposure to

C. tetani spores, which can enter through unclean delivery practices.

Choice C rationale:

Advising against disposing of animal feces properly is not directly related to preventing tetanus. Tetanus is primarily caused by the introduction of

C. tetani spores into wounds, not through exposure to animal feces.

Choice D rationale:

Educating on avoiding contact with soil or feces that may contain

C. tetani spores is essential in preventing tetanus. The spores can be found in soil and feces, and direct contact with these sources increases the risk of infection.

Choice E rationale:

Suggesting regular booster doses of DTP vaccine during adulthood is an effective measure in preventing tetanus. The DTP vaccine provides immunity against tetanus, and regular boosters are recommended to maintain protection throughout life.
