A nurse is reinforcing discharge teaching with a client who has angina and a prescription for sublingual nitroglycerin tablets. Which of the following statements by the client indicates an understanding of the teaching?

Answer: B. Client isolates themselves from their family and friends

Rationale: A crisis is a situation that overwhelms a person's usual coping mechanisms and causes psychological distress. A client who isolates themselves from their family and friends is showing a sign of impaired social functioning, which indicates a crisis. The other options are not specific to a crisis and could be manifestations of anxiety or depression.

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.
