Choice A rationale:
Hourly neurologic checks are not the priority intervention for a client with hypokalemia. While hypokalemia can cause neuromuscular changes, such as muscle weakness and cramps, these are not typically the most immediate or life-threatening concerns.
Cardiac monitoring is crucial to detect and manage potentially fatal arrhythmias promptly.

Neurologic checks can be implemented as part of the overall assessment and monitoring plan, but they should not supersede cardiac monitoring in this situation.
Choice C rationale:
Seizure precautions are not routinely initiated for clients with hypokalemia unless there is a specific seizure history or other neurological concerns.
Hypokalemia can cause neuromuscular irritability, but it does not directly trigger seizures in most cases. The priority remains cardiac monitoring due to the significant risk of arrhythmias.
Choice D rationale:
Administering oxygen via face mask might be considered if the client exhibits respiratory distress or hypoxemia. However, it's not the immediate priority intervention for hypokalemia without accompanying respiratory compromise.
Hypokalemia primarily affects cardiac conduction, necessitating prompt cardiac monitoring.
Oxygen therapy can be administered if clinically indicated, but it does not address the underlying electrolyte imbalance.
Rationale for the correct answer, B:
Initiating cardiac monitoring is the most crucial nursing action for a client with a serum potassium level of 2.8 mEq/L. Here's a detailed explanation:
Hypokalemia's significant cardiac effects:
Potassium is essential for normal cardiac conduction and muscle contraction. Hypokalemia disrupts the electrical activity of the heart, potentially leading to:
Arrhythmias (irregular heartbeats), including potentially fatal ones like ventricular tachycardia or fibrillation. Electrocardiogram (ECG) changes, such as ST segment depression, T wave flattening or inversion, and prominent U waves. Cardiac monitoring's role:
Continuously tracks the heart's electrical activity. Enables early detection of arrhythmias.
Facilitates prompt intervention to prevent life-threatening complications. Specific benefits of cardiac monitoring in hypokalemia:

Allows for early identification and treatment of arrhythmias, potentially preventing cardiac arrest. Guides electrolyte replacement therapy, ensuring appropriate potassium administration.
Assesses the effectiveness of interventions, ensuring the patient's stability.

Choice A rationale:
Anaphylaxis risk: A history of allergy to bee and wasp stings indicates a potential risk for anaphylaxis, a severe and life- threatening allergic reaction. This information is crucial for the surgical team to be aware of, as it can influence their choice of anesthesia, medications, and other interventions during the surgery. They will need to be prepared to manage any potential allergic reactions promptly and effectively.
Cross-reactivity potential: Allergies to insect stings can sometimes cross-react with other substances, such as medications used during surgery (e.g., antibiotics, muscle relaxants, latex). It's essential for the surgical team to be aware of these potential cross-reactions to take necessary precautions and avoid triggering an allergic reaction.
Preoperative planning: Knowing about the patient's allergy to bee and wasp stings allows the surgical team to make informed decisions regarding:
Premedication: The patient may need to receive antihistamines or corticosteroids before surgery to reduce the risk of an allergic reaction.
Monitoring: The patient's vital signs and symptoms will be closely monitored during and after surgery for any signs of an allergic reaction.
Emergency preparedness: The surgical team will have medications and equipment readily available to treat anaphylaxis if it occurs.
Choice B rationale:
Lactose intolerance is not typically a significant concern during surgery. It's a digestive issue that can cause discomfort after consuming dairy products, but it doesn't typically pose immediate risks during surgical procedures. The surgical team may adjust the patient's diet after surgery to accommodate lactose intolerance, but it's not crucial information for the immediate surgical planning.
Choice C rationale:
Herb and supplement use is important to communicate to the surgical team. Some herbs and supplements can interact with medications used during surgery, increasing the risk of bleeding, heart problems, or other complications. However, it's not as immediately critical as an allergy to bee and wasp stings, which carries a risk of life-threatening anaphylaxis.
Choice D rationale:
While a patient's previous experience with surgery can be helpful for the surgical team to understand their anxiety levels and expectations, it's not as critical as information about allergies or potential medication interactions.
