A nurse is caring for a group of toddlers receiving digoxin therapy. For which of the following toddlers should the nurse revise the plan of care?
A toddler who has vomited 2 times in the last hour
A toddler who has a digoxin level of 1.2 ng/mL (0.8 to 2 ng/mL)
A toddler who has an apical pulse of 100/min
A toddler who has a potassium level of 4.0 mEq/L (3.4 to 4.7 mEq/L)
The Correct Answer is A
Vomiting can lead to decreased absorption of digoxin, potentially resulting in subtherapeutic levels and inadequate therapeutic effect. The plan of care should be revised to address the vomiting and consider alternative routes of administration or doses.
A digoxin level within the therapeutic range indicates adequate drug absorption and effectiveness.
An apical pulse of 100/min is within the expected range for toddlers and does not necessarily require a revision of the plan of care related to digoxin therapy.
A potassium level within the normal range is desirable and does not necessarily require a revision of the plan of care related to digoxin therapy.

Correct Answer is D
Explanation
A. Assessing both eyes together first, then separately, is not a typical method for assessing visual acuity in children.
B. Positioning the child 4.6 meters (15 feet) from the chart is not practical for testing visual acuity in a clinical setting.
C. Testing the child without glasses before testing with glasses may be appropriate but is not specifically related to the method of visual acuity assessment.
D. Using a tumbling E chart is appropriate for assessing visual acuity in young children who may not recognize letters. The tumbling E chart uses a series of "E" shapes facing different directions, allowing the child to indicate the direction the "E" is facing, thus assessing visual acuity.
