A nurse is assessing a toddler who has suspected lead poisoning. Which of the following findings should the nurse expect the client to manifest with acute lead poisoning?

A. 3 months:

By 3 months of age, infants typically experience rapid growth, but their birth weight usually does not double by this time. Infants usually gain weight at a steady rate during the first few months of life, but doubling birth weight typically occurs later in infancy.

B. 9 months:

By 9 months of age, infants continue to grow and develop, but their birth weight usually doubles before this age. While infants may have more than doubled their birth weight by 9 months, it's generally expected to occur earlier in infancy.

C. 6 months:

Correct. Birth weight typically doubles by around 6 months of age. This milestone reflects the rapid growth and development that occurs during the first half-year of life. By 6 months, infants have typically established feeding routines and experienced significant weight gain since birth.

D. 12 months:

By 12 months of age, infants have completed their first year of life, and their growth and development continue at a slightly slower pace compared to earlier months. Doubling birth weight usually occurs earlier, around 6 months, rather than by 12 months.

Answer:

below 90 beats per minute (bpm)

Rationale:

For infants, especially those receiving digoxin, the heart rate is a critical parameter to monitor due to the medication's potential to affect cardiac function.

The general guideline for withholding digoxin in infants is if the apical heart rate is below 90 beats per minute (bpm) in infants. Therefore, the nurse should withhold the dose if the infant's apical heart rate is less than 90 bpm.

It's important to note that specific institutional protocols may vary, so nurses should always adhere to the guidelines established by their facility. Additionally, if the infant's heart rate is below the threshold, the nurse should promptly notify the healthcare provider for further evaluation and guidance.
