The nurse is caring for a patient on contact precautions. Which action will be most appropriate to prevent the spread of disease?

A) "Would you like to talk about your concerns?": This response acknowledges the client's feelings and offers support and an opportunity to discuss their concerns further. It respects the client's autonomy and allows them to express their thoughts and feelings about the situation.
B) "Why don't you want to tell your partner your diagnosis?": This response may come across as confrontational and judgmental, potentially making the client feel defensive. It does not facilitate open communication or address the client's concerns in a supportive manner.
C) "If I were you, I would tell my partner.": This response imposes the nurse's values and beliefs on the client, which may not be helpful or appropriate. It undermines the client's autonomy and decision-making process.
D) "Most people find it helpful to talk to their partner.": While this statement may be true for some individuals, it assumes that the client's situation is the same as others and does not take into account the client's unique circumstances and preferences. It does not encourage open dialogue or address the client's concerns directly.

Potassium Levels: The postoperative potassium level for the client is 3.0 mEq/L, which falls below the normal range of 3.5 to 5 mEq/L. Potassium is a critical electrolyte necessary for the proper functioning of cardiac muscles. It plays a pivotal role in maintaining the electrical conductivity of the heart. Hypokalemia, or low potassium levels, can disrupt this electrical conductivity, leading to abnormal heart rhythms or arrhythmias. Arrhythmias can manifest as palpitations, irregular heartbeats, or more severe cardiac events, which can be life-threatening if not addressed promptly.

Importance of Potassium in Cardiac Function: Potassium is essential for the repolarization phase of the cardiac action potential. It helps in the return of the cell to its resting state after each heartbeat. A deficiency in potassium disrupts this balance, increasing the risk of erratic heartbeats and arrhythmias. Low potassium can prolong the QT interval on an electrocardiogram (ECG), which is a marker for potential arrhythmic events.

Clinical Implications: For a postoperative client, maintaining electrolyte balance is crucial. Surgery and anesthesia can affect fluid and electrolyte levels, making it essential to monitor and correct any imbalances. The decrease in potassium levels from 3.5 mEq/L preoperatively to 3.0 mEq/L postoperatively highlights a trend that must be addressed to prevent complications such as arrhythmias.

Preventative Measures: To mitigate the risk of arrhythmias, the healthcare team should consider interventions to correct the hypokalemia. This may include administering potassium supplements orally or intravenously, depending on the severity and clinical context. Continuous cardiac monitoring may also be warranted to detect and manage any emerging arrhythmic events promptly.
