Increased heart rate.

Discomfort at the puncture site.

A nurse is monitoring a client following a thoracentesis. The nurse should identify which of the following manifestations as a complication and contact the provider immediately?

Choice A rationale
Hypercyanotic spells, also known as “tet spells,” are typically associated with Tetralogy of Fallot, a congenital heart defect. The child in this scenario has congenital mitral stenosis, not Tetralogy of Fallot, making hypercyanotic spells less likely.
Choice B rationale
A murmur is a sound made by turbulent blood flow within the heart. While the child may have a murmur due to congenital mitral stenosis, it is not a direct risk associated with the exacerbation of heart failure. The primary concern here is the risk of digitalis toxicity due to the administration of furosemide.
Choice C rationale
Digitalis toxicity is a significant risk for this child. Furosemide, a diuretic, can cause electrolyte imbalances, particularly hypokalemia, which increases the risk of digitalis toxicity. Symptoms of digitalis toxicity include nausea, vomiting, dizziness, and arrhythmias.
Choice D rationale
Dependent rubor is a reddish-blue discoloration of the extremities, typically associated with peripheral arterial disease. It is not directly related to heart failure or the administration of furosemide.
Choice E rationale
Fever is not a typical complication of heart failure or the administration of furosemide. It is more commonly associated with infections or inflammatory conditions.
Choice F rationale
Carditis, or inflammation of the heart, is not a direct risk associated with the exacerbation of heart failure or the administration of furosemide. The primary concern remains digitalis toxicity.

Choice A rationale
The skin assessment reveals bruising and petechiae, which are signs of thrombocytopenia, a condition where the blood has a lower than normal number of platelets. This is significant in a child with leukemia as it may indicate a relapse or bone marrow suppression. The presence of petechiae and unexplained bruising should be reported to the provider as they can be indicative of bleeding disorders or a decrease in platelet count.
Choice B rationale
Oxygen saturation of 92% on room air is below the normal range (95-100%) for a child. This indicates hypoxemia, which can be a sign of respiratory distress or other underlying conditions. Given the child’s history of an upper respiratory infection and leukemia, this finding is critical and should be reported to the provider to ensure appropriate interventions are taken to improve oxygenation.
Choice C rationale
The WBC count is crucial in a child with leukemia. An abnormal WBC count can indicate an infection, relapse, or bone marrow suppression. Monitoring the WBC count helps in assessing the child’s immune status and the effectiveness of the leukemia treatment. Any significant changes in the WBC count should be reported to the provider for further evaluation and management.
Choice D rationale
Subcostal retractions are a sign of increased work of breathing and respiratory distress. This finding, along with the child’s statement of feeling like they can’t breathe, indicates that the child is struggling to maintain adequate ventilation. Reporting this to the provider is essential for timely intervention to prevent further respiratory compromise.
Choice E rationale
An ongoing upper respiratory infection for the last 2 months that has not resolved is concerning, especially in a child with a history of leukemia. This could indicate an underlying immunodeficiency or a more serious infection that requires further investigation and treatment. Reporting this to the provider is necessary to address the persistent infection and prevent complications.
Choice G rationale
The respiratory rate is an important vital sign that can indicate respiratory distress or other underlying conditions. An abnormal respiratory rate, whether too high or too low, can be a sign of respiratory or metabolic issues. Monitoring and reporting the respiratory rate to the provider helps in assessing the child’s respiratory status and determining the need for further intervention.
