question 3

a 9 - month - old infant has developed two teeth since the 6 - month checkup. the local water supply contains fluoride. what will the primary care nurse practitioner do to promote healthy dentition at this visit?

Explanation:

Question 1

To determine the correct answer, we analyze each option:

• "Height growth accelerates during this period": Height growth slows after infancy, so this is incorrect.
• "Usual weight gain is 4 pounds per month starting at 12 months": Weight gain slows, not 4 pounds monthly, so incorrect.
• "Most infants have transitioned to 3 meals with two snacks": By 12 months, infants typically move to this meal pattern, which is correct.
• "Infants should be introduced to peanuts at this age": Peanut introduction can be earlier (around 6 months with guidance), so incorrect.

Step 1: Calculate weight loss

First, find the weight loss: Initial weight = 3.56 kg, Final weight = 3.25 kg. Weight loss = \( 3.56 - 3.25 = 0.31 \) kg.

Step 2: Calculate percentage weight loss

Use the formula \( \text{Percentage weight loss} = \frac{\text{Weight loss}}{\text{Initial weight}} \times 100 \). Substitute values: \( \frac{0.31}{3.56} \times 100 \approx 8.71\% \), which is approximately 9%.

If local water has fluoride, the nurse practitioner would likely recommend no fluoride supplement (or monitor, as water fluoridation is beneficial). If the question is about promoting healthy dentition with fluoride - containing water, the action would be to confirm water fluoridation is adequate and advise on oral hygiene. (Since the full question is not visible, but based on context: If water has fluoride, no additional fluoride supplement is needed, and advise on brushing, diet, etc. to promote dental health.)

Answer:

Most infants have transitioned to 3 meals with two snacks.
