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.

Correct Answer is B
Explanation
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 ["6"]
Explanation
Step 1 is to set up the equation to solve for the unknown, which is the volume in mL. The equation is (300 mg ÷ 250 mg) × 5 mL.
Step 2 is to perform the calculation: (300 mg ÷ 250 mg) × 5 mL = 6 mL. So, the nurse should administer 6 mL of amoxicillin oral solution.
