A nurse is taking care of a patient who has just had a central venous access line inserted. What is the next step the nurse should ensure is completed?

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:
Planning activities to prevent fatigue is a valid self-care strategy for SLE patients. Fatigue is a common symptom of SLE, and it can be exacerbated by overexertion. By planning activities and pacing themselves, patients can help to manage their fatigue and conserve energy.
Fatigue management strategies include:
Prioritizing tasks and delegating when possible.
Breaking down large tasks into smaller, more manageable ones. Taking frequent rest breaks throughout the day.
Maintaining a regular sleep schedule. Engaging in moderate exercise, as tolerated.
Avoiding caffeine and alcohol, which can interfere with sleep.
Addressing any underlying health conditions that may be contributing to fatigue, such as anemia or depression.
Choice B rationale:
Prioritizing rest is another essential self-care strategy for SLE patients. Rest allows the body to conserve energy and repair itself. Patients with SLE may need more rest than healthy individuals, especially during flares.
Resting strategies include:
Getting enough sleep at night. Napping during the day, as needed.
Taking breaks from activities throughout the day.
Practicing relaxation techniques, such as deep breathing or meditation.
Choice C rationale:
Sunbathing is not recommended for SLE patients, as it can trigger flares. Ultraviolet (UV) radiation from the sun can damage skin cells and exacerbate inflammation in SLE patients. This can lead to a flare-up of symptoms, such as skin rash, joint pain, and fatigue.
Sun protection strategies include:
Avoiding direct sunlight, especially during the middle of the day when UV rays are strongest. Wearing protective clothing, such as long-sleeved shirts, pants, and wide-brimmed hats.
Using sunscreen with an SPF of 30 or higher on a daily basis.
Applying sunscreen liberally and reapplying it every two hours, or more often if sweating or swimming.
Choice D rationale:
Avoiding direct sunlight is a correct self-care strategy for SLE patients.
