A nurse is educating a new mother about umbilical cord care and how to prevent omphalitis, sepsis, and tetanus.
Which of the following statements by the mother indicates an understanding of the teaching?
“I should wash my hands before and after handling the cord stump.”
“I should apply petroleum jelly or ointment to the cord stump after each diaper change.”
“I should use a cotton swab dipped in hydrogen peroxide to clean around the base of the cord stump.”
“I should fold down the top of the diaper below the cord stump until it falls off.”
The Correct Answer is A
The correct answer is choice A. Washing hands before and after handling the cord stump can prevent the transmission of bacteria that can cause omphalitis, sepsis, and tetanus.
Choice B is wrong because applying petroleum jelly or ointment to the cord stump can delay its drying and increase the risk of infection.
Choice C is wrong because using hydrogen peroxide to clean the cord stump can damage the healthy tissue and delay healing.
Choice D is wrong because folding down the diaper below the cord stump can expose it to urine and feces, which can contaminate it and cause infection.
The normal range for umbilical cord separation is 5 to 15 days after birth.
