A nurse is caring for an infant who has necrotizing enterocolitis. Which of the following findings should the nurse expect?

The correct answer is Choice B.

Choice A rationale

Applying a cool pack to the heel prior to the procedure is not recommended as it can constrict blood vessels and make it more difficult to obtain a blood sample.

Choice B rationale

Puncturing the outer aspect of the heel is the correct technique for collecting a capillary blood specimen from an infant. This area has fewer nerve endings and is less likely to cause pain or injury.

Choice C rationale

Using a surgical blade to obtain the specimen is not appropriate for a capillary blood draw. A lancet should be used instead to make a small puncture in the skin.

Choice D rationale

Wiping the site with alcohol after the puncture is not recommended as it can cause irritation and discomfort. The site should be cleaned with alcohol before the puncture and then covered with a sterile gauze pad after the procedure. .

The correct answer is D. Varicella.

Choice A rationale

Rotavirus vaccination is typically administered in infancy, not at 5 years of age. The rotavirus vaccine is given to infants to protect against rotavirus infections, which can cause severe diarrhea and dehydration in young children. By the age of 5, children have usually completed the rotavirus vaccination series.

Choice B rationale

Hepatitis B vaccination is also typically completed in infancy. The hepatitis B vaccine is given to infants to protect against hepatitis B virus infection, which can cause chronic liver disease and liver cancer. By the age of 5, children who are up-to-date with their immunizations have usually completed the hepatitis B vaccination series.

Choice C rationale

Haemophilus influenzae type b (Hib) vaccination is typically completed by 15 months of age. The Hib vaccine protects against infections caused by Haemophilus influenzae type b, such as meningitis, pneumonia, and epiglottitis. By the age of 5, children who are up-to-date with their immunizations have usually completed the Hib vaccination series.

Choice D rationale

The second dose of the varicella vaccine is usually given at 4-6 years of age. The varicella vaccine protects against chickenpox, a highly contagious viral infection that causes an itchy

rash and fever. Administering the second dose of the varicella vaccine at this age helps ensure that the child has adequate immunity against chickenpox.
