A nurse is preparing to measure an infant's vital signs. The nurse should use which of the following sites to assess a heart rate?

A. An anxiety reaction: The toddler's behavior of sitting quietly, sucking her thumb, and turning away from the nurse when approached after her mother leaves the room suggests anxiety. These

behaviors are common signs of distress or discomfort in young children, especially when separated from their primary attachment figure (in this case, the mother).

B. Regression: Regression involves reverting to earlier, more immature behaviors in response to stress or discomfort. While thumb sucking can be considered a form of regression, the behavior observed in this scenario is more indicative of anxiety rather than a broader regression in

developmental milestones.

C. Resentment toward the mother: There is no evidence in the scenario to suggest that the toddler is expressing resentment toward the mother. The behaviors observed are more likely related to

the child's emotional response to separation and hospitalization.

D. Developing autonomy: Developing autonomy typically involves asserting independence and exploring one's environment. The behaviors observed in the scenario are more indicative of anxiety and distress rather than autonomous behavior.

A. "His average daily intake should be about 3,000 calories.": This statement is incorrect because the average daily calorie intake for a toddler is much lower, typically ranging from 1,000 to 1,400 calories, depending on factors such as age, weight, and activity level.

B. "The quality of food I provide him is more important than the quantity.": This statement reflects an understanding of the importance of nutrient-dense foods in a toddler's diet rather than focusing solely on the quantity of calories consumed.

C. "Because he is such a picky eater, I will give him one of my vitamins each day.": While offering a vitamin supplement may seem like a solution to address nutritional gaps, it's important for toddlers to receive essential nutrients from a variety of foods rather than relying solely on supplements.

D. "I should expect him to have an increased appetite.": While toddlers may experience fluctuations in appetite, expecting a consistently increased appetite may not be accurate or indicative of healthy eating habits.
