A nurse is caring for a 24-week-old infant whose mother requests additional information about sudden infant death syndrome (SIDS). Which of the following responses should the nurse make?

“Sleep apnea is the main cause of SIDS.”.

“You should place your baby on her back when sleeping to decrease the risk of SIDS.”.

“SIDS rates have been rising over the last 10 years.”.

“SIDS is directly correlated to diphtheria, tetanus, and pertussis vaccines.”. .

Answer and Explanation

The Correct Answer is B

Choice A rationale

While sleep apnea has been associated with SIDS, it is not considered the main cause. SIDS is a complex syndrome that is likely caused by a combination of genetic, environmental, and physiological factors.

Choice B rationale

Placing a baby on their back to sleep is one of the most effective ways to reduce the risk of SIDS. This position allows for optimal oxygenation and minimizes the risk of suffocation.

Choice C rationale

SIDS rates have actually been decreasing over the last 10 years due to increased awareness and education about safe sleep practices.

Choice D rationale

There is no evidence to suggest that the diphtheria, tetanus, and pertussis vaccines are directly correlated with SIDS. In fact, immunizations are an important part of maintaining a baby’s health and reducing the risk of serious illness. Down syndromeDown syndrome Explore

Correct Answer is B

Explanation

Choice A rationale

While some babies may experience rapid growth and double their birth weight within the first 3 months, this is not typically expected. Most infants are expected to double their birth weight by 5 to 6 months of age.

Choice B rationale

Most infants are expected to double their birth weight by 5 to 6 months of age. Therefore, by the age of 6 months, it would be expected for an infant to have doubled their birth weight.

Choice C rationale

By 9 months, most infants would have already doubled their birth weight. The typical expectation is for infants to double their birth weight by 5 to 6 months of age.

Choice D rationale

By 12 months, most infants would have already doubled their birth weight and are on their way to tripling their birth weight. Therefore, expecting an infant to double their birth weight by 12 months would be beyond the typical timeframe.

A. “My baby will be placed under special lights if the test is elevated.”. B. “Sometimes the test is repeated in the doctor’s office at the 2-week check-up.”. C. “My baby must take formula or breast milk before the test is done.”. D. “This test checks for a genetic disorder that can be corrected by diet.”.

Correct Answer is A

Explanation

Choice A rationale

The statement “My baby will be placed under special lights if the test is elevated” indicates a need for further teaching. This statement is incorrect because phototherapy (special lights) is not used to treat phenylketonuria (PKU). PKU is a genetic disorder that results in the body’s inability to metabolize the amino acid phenylalanine. If left untreated, it can lead to intellectual disability and other serious health problems. The treatment for PKU involves a special diet that is low in phenylalanine. Therefore, the parent’s statement about using special lights for treatment indicates a misunderstanding about the nature of PKU and its treatment.

Choice B rationale

The statement “Sometimes the test is repeated in the doctor’s office at the 2-week check-up” is correct. PKU is usually diagnosed through a routine newborn screening test, and if the initial test results are positive or unclear, the test may be repeated.

Choice C rationale

The statement “My baby must take formula or breast milk before the test is done” is correct. For accurate results, the PKU test is done after the baby is 24 hours old and after the baby has had some protein in the diet.

Choice D rationale

The statement “This test checks for a genetic disorder that can be corrected by diet” is correct. PKU is a genetic disorder that can be managed with a special diet low in phenylalanine.
