A nurse is preparing to collect a capillary blood specimen from the heel of a 4-month-old infant. Which of the following actions should the nurse take?

A. Soy milk is not recommended for infants under one year of age. It does not provide the necessary nutrients for their growth and development.

B. Commercially prepared infant formula is specifically designed to meet the nutritional needs of infants. It is the best alternative to breast milk for infants having difficulty eating.
C. While warming milk might be comforting, it does not address the underlying issue of goat milk being an inappropriate nutritional source for a 10-month-old infant.
D. Breast milk is the best source of nutrition for infants. However, if breastfeeding is not possible, formula is the next best option.

A. The Tumbling E chart is a suitable tool for assessing visual acuity in young children who may not yet know their letters. It uses the letter "E" in various orientations (up, down, left, right), and the child is asked to identify the direction the "E" is facing. This method is appropriate for children who are at least 3 years old and can follow simple directions.
B. In a visual acuity assessment, it is typically standard to test each eye separately after assessing both eyes together. Testing both eyes together initially can help gauge how the child performs with their full visual capability, but it’s essential to test each eye individually to accurately determine if there is a difference in visual acuity between the two eyes.
C. For a visual acuity test using a standard Snellen chart, positioning the child 4.6 meters (15 feet) away from the chart is correct. However, younger children, especially those who might not be able to focus or remain still at that distance, may sometimes be tested from a shorter distance. For preschool-aged

children, the testing distance can be adapted to accommodate their ability to focus and understand the task.
D. Testing visual acuity without glasses first is not the recommended approach if the child already wears corrective lenses. If the child uses glasses or other corrective lenses, you should assess their visual acuity with the glasses on, as this provides the most accurate representation of their vision with their current correction.
