A nurse is planning the discharge of an infant who has tetralogy of Fallot. The nurse anticipates the need for which of the following equipment?

A. Administering furosemide may also be appropriate for managing heart failure symptoms, but the priority action based on the client's condition is to withhold digoxin.

B. The client's vital signs indicate bradycardia (pulse 52/min), which is a common adverse effect of digoxin, especially in the setting of heart failure. Withholding digoxin is necessary to prevent further exacerbation of bradycardia and potential toxicity.

C. Withholding spironolactone may be considered if there are concerns about electrolyte imbalances, but it is not the priority action in this scenario.

D. Administering ferrous sulfate is not indicated based on the client's chart findings; there is no indication of anemia or iron deficiency.

A. Constipation is not typically associated with TPN because the client is receiving nutrients intravenously rather than through the gastrointestinal tract.

B. Respiratory depression is not a direct complication of TPN administration.

C. Hypotension is not a common complication of TPN unless associated with fluid shifts or infection.

D. Electrolyte imbalance is a potential complication of TPN due to the high concentrations of glucose, electrolytes, and other nutrients. Rapid infusion, improper formulation, or abrupt discontinuation can lead to imbalances in sodium, potassium, calcium, magnesium, and phosphate. Frequent monitoring of laboratory values is essential to prevent metabolic complications.
