A nurse is collecting data from an infant at a well-child visit.
The nurse should expect the infant to double his birth weight by which of the following ages?
3 months.
6 months.
9 months.
12 months.
The Correct Answer is B
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.

The correct order of Erikson’s stages of growth is B, D, A, C.
Correct Answer is C
Explanation
Choice A rationale
The ventrogluteal site is not typically used for immunizations in infants. This site is often used in older children and adults, but it is not the preferred site for infants due to their small muscle mass.
Choice B rationale
The deltoid site is not typically used for immunizations in infants. This site is often used in older children and adults, but it is not the preferred site for infants due to their small muscle mass.
Choice C rationale
The vastus lateralis is the preferred site for administering immunizations in infants. This muscle is located in the thigh and is large enough to accommodate the injection. It is also away from major nerves and blood vessels, making it a safe site for injections.
Choice D rationale
The dorsogluteal site is not recommended for immunizations in any age group. This site has a number of large blood vessels and nerves, as well as a layer of fat, which can make injections less effective and potentially harmful.
