A client with a congenital heart disease is undergoing diagnostic testing. The client asks the nurse about the purpose of the tests. What is the nurse's best response?

A) Incorrect. Taking an over-the-counter pain reliever may not address the underlying cause of the symptoms and is not the appropriate action in this situation.

B) Incorrect. Deep breathing exercises may not alleviate the symptoms of shortness of breath and chest pain. The client should seek medical attention for proper evaluation and management.

C) Incorrect. While resting quietly is generally advisable, it may not be sufficient to address the client's symptoms. Seeking medical attention is essential to identify and manage the cause of the symptoms.

D) The answer is D. Shortness of breath and chest pain can be signs of a cardiac event or worsening of the congenital heart disease. The client should seek medical attention immediately to receive appropriate evaluation and treatment.

A) Correct answer. Weight gain and edema in the lower extremities can be signs of worsening heart failure in children with congenital heart defects. Fluid retention occurs due to the heart's inability to effectively pump blood, leading to fluid accumulation in the body.

B) This option is incorrect. While decreased heart rate and blood pressure within the normal range may be indicative of stable heart function, they are not specific indicators of worsening heart failure.

C) This option is incorrect. Improved appetite and increased physical activity level are positive indicators but do not specifically reflect the child's heart failure status.

D) This option is incorrect. Resolution of cyanosis and pink coloration of the lips and nail beds are positive signs of improved oxygenation and may indicate effective management of the heart defect but not the potential worsening of heart failure.
