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

Choice A rationale:

Chickenpox and shingles are viral infections, and while they can cause systemic symptoms, they are not directly linked to heart disease.

Choice B rationale:

The complications of chickenpox go beyond bacterial skin infections. While bacterial superinfections are possible, the more severe complications are associated with the virus itself.

Choice C rationale:

Shingles is characterized by a localized rash along the distribution of a sensory nerve, not a generalized vesicular rash.

Choice D rationale:

Complications of both chickenpox and shingles include pneumonia, encephalitis (inflammation of the brain), and postherpetic neuralgia (persistent nerve pain following shingles) These complications can be serious and require medical attention.

Choice A rationale:

(Incorrect) The herpes zoster vaccine (shingles vaccine) is not administered to patients with chickenpox. The vaccine is recommended for those aged 50 years and older to prevent shingles in individuals who have previously had chickenpox.

Choice B rationale:

(Incorrect) Encouraging contact with immunocompromised individuals is not appropriate when caring for a patient with chickenpox. Immunocompromised individuals are more susceptible to severe complications from the varicella-zoster virus, so close contact should be avoided.

Choice C rationale:

(Correct) Using cool compresses is an essential comfort measure for patients with chickenpox. Cool compresses can help soothe the itching and discomfort caused by the chickenpox rash.

Choice D rationale:

(Incorrect) Providing educational materials only to the patient is not sufficient. It is important for the nurse to educate the patient's family members or caregivers about chickenpox precautions and care to prevent further transmission of the virus.
