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?

C) Incorrect. Dairy products rich in calcium are not contraindicated with enalapril use. Calcium and ACE inhibitors do not have direct interactions.

D) Incorrect. Foods high in vitamin B12 are not contraindicated with enalapril use. There is no specific dietary restriction regarding vitamin B12 intake for clients taking this medication.

A) The answer is A. Before administering furosemide, it is essential to assess the child's respiratory rate because this medication is a loop diuretic that can lead to fluid and electrolyte imbalances, including hypokalemia. Respiratory rate assessment helps monitor for signs of respiratory distress, especially in clients with heart failure.

B) Incorrect. While monitoring the child's blood pressure is essential, it is not the priority action before administering furosemide. Blood pressure may be affected by the diuretic action of the medication, but respiratory status is more critical to assess initially.

C) Incorrect. Although monitoring electrolyte levels is important when administering furosemide, it is not the priority action. Assessing the child's respiratory rate takes precedence to identify any respiratory distress.

D) Incorrect. Determining the child's weight is relevant in assessing the effectiveness of furosemide therapy. However, it is not the priority action before administering the medication. Respiratory assessment is more critical for immediate intervention.
