A nurse is caring for a client who has heart failure.
Which of the following manifestations should the nurse expect?

The correct answer is choice C: Initiate continuous cardiac monitoring.

Choice A rationale:

Implementing fluid restrictions is not recommended for a child with diabetic ketoacidosis (DKA). DKA is characterized by severe dehydration due to osmotic diuresis, and fluid replacement is a critical component of treatment to restore hydration and circulatory volume.

Choice B rationale:

Monitoring vital signs every 8 hours is not sufficient for a child with DKA. DKA is an acute, life-threatening condition that requires close monitoring of vital signs to detect changes in the patient’s condition promptly. Vital signs should be monitored more frequently, typically every 1 to 2 hours, depending on the severity of the DKA and institutional protocols.

Choice C rationale:

Continuous cardiac monitoring is recommended for a child with DKA. DKA can lead to serious electrolyte imbalances, such as hypokalemia, which can cause cardiac arrhythmias. Continuous cardiac monitoring allows for the early detection and treatment of these potential complications.

Choice D rationale:

Administering subcutaneous insulin 30 minutes before meals is not appropriate for the acute management of DKA. In DKA, insulin is typically administered intravenously to rapidly decrease blood glucose levels and correct metabolic acidosis. Subcutaneous insulin is not used until the patient is stable and able to eat.
