A nurse is teaching the parents of a school-age child who is newly diagnosed with juvenile idiopathic arthritis. Which of the following interventions should the nurse include in the teaching?

Choice A reason:

"Repeat the dose if your child vomits within 1 hour after taking the medication." This statement is incorrect. If a child vomits within 1 hour after taking digoxin, the parents should not repeat the dose. The reason is that the child may have already absorbed a sufficient amount of the medication before vomiting, and an additional dose could lead to digoxin toxicity.

Choice B reason:

"You can add the medication to a half-cup of your child's favourite juice." This statement is incorrect. Adding digoxin to juice or any other food or drink is not recommended. Digoxin should be administered separately and not mixed with food or liquids to ensure accurate dosing and prevent potential interactions with other substances.

Choice C reason:

"Have your child drink a small glass of water after swallowing the medication." This statement is correct. Giving a small glass of water after administering digoxin helps ensure that the medication is fully swallowed and goes into the stomach, reducing the risk of it being retained in the mouth or throat.

Choice D reason:

"Limit your child's potassium intake while she is taking this medication." This statement is not accurate. Digoxin is often prescribed in conjunction with other heart failure medications, some of which may impact potassium levels. However, the parents should not arbitrarily limit the child's potassium intake without specific instructions from the healthcare provider. The healthcare provider will monitor the child's potassium levels and adjust the treatment plan as necessary.

The client is at risk for experiencing electrolyte imbalance due to the vomiting. Persistent vomiting during pregnancy, especially with significant weight loss, can lead to electrolyte imbalances such as hypokalemia, hyponatremia, or metabolic alkalosis. This can result from the body's inability to retain essential minerals and fluids. The client’s reported diet of minimal food intake, primarily consisting of toast and pretzels, indicates inadequate nutrition and potential for further exacerbation of these imbalances.

The significant weight loss of 6.8 kg (15 lb) within a month and continuous nausea and vomiting are concerning symptoms that warrant immediate medical evaluation. The nurse’s advice to seek a provider’s assessment underscores the need for timely intervention to address potential complications, ensure maternal and fetal health, and possibly prescribe antiemetic medications or other treatments to manage symptoms.
