An infant with an unrepaired tetralogy of Fallot defect is becoming extremely cyanotic during a routine blood draw. Which interventions should the nurse implement? Place in order from the highest-priority intervention to the lowest-priority intervention. Provide the answer using lowercase letters separated by commas (e.g., a, b, c, d).

Correct Answer: B

Correct Answer: B

Rationale: Hypernatremia is a condition characterized by high levels of sodium in the blood. When hypernatremia is treated too rapidly or aggressively, a rapid decrease in serum sodium levels may occur. This rapid change in serum sodium concentration can cause water to move into brain cells, leading to cerebral edema. Cerebral edema is a dangerous complication associated with the potential to cause increased intracranial pressure, neurological deficits, and even death. It is crucial to correct hypernatremia slowly and carefully to prevent such complications.

Correct Answer: D

Rationale: Too rapid infusion of hyperalimentation solutions can lead to circulatory overload due to the rapid volume expansion, which can strain the heart and lead to fluid overload. This can manifest as symptoms such as shortness of breath, crackles in the lungs, and edema. Additionally, a rapid infusion rate can cause a sudden surge in glucose levels, potentially leading to hypoglycemia due to increased insulin release in response to the elevated glucose levels. It is important for the nurse to maintain a careful and appropriate infusion rate to prevent these complications and ensure patient safety.

Correct Answer: C

Rationale: When suctioning a patient, it is important to limit the suctioning time to avoid hypoxia and tissue trauma. The maximum recommended time for suctioning an adult patient is usually around 10-15 seconds. However, in some cases, such as when dealing with thick or excessive secretions, the maximum time can be extended up to 30 seconds. In this particular case, where James is likely experiencing respiratory distress due to his symptoms, it would be appropriate for Wilma to suction him for a maximum of 30 seconds to effectively clear his airways while minimizing the risk of complications.

Correct Answer: D

Rationale: A potassium level of 6.3 mEq/L indicates hyperkalemia, which can have significant effects on the heart. The heart is one of the most sensitive organs to changes in potassium levels. In hyperkalemia, elevated serum potassium levels can lead to various cardiac manifestations, including dysrhythmias, conduction abnormalities, and eventually cardiac arrest. Monitoring and managing potassium levels are crucial in preventing life-threatening cardiac complications in patients with hyperkalemia. While the kidneys and other organs can also be affected by high potassium levels, the heart is the most critical organ to consider in this scenario.
