A nurse is attending to a client with a peripheral vascular access device who is experiencing pain, redness, and swelling at the site. What action should the nurse take to alleviate the pain after removing the device?

Choice A rationale:
Utilizing a respirator when handling urine output is not the most appropriate action for a nurse caring for a patient with MRSA.
MRSA is not typically transmitted through the air, but rather through direct contact with infected wounds or contaminated surfaces.
While a respirator may offer some protection against airborne particles, it is not necessary for routine care of a patient with MRSA.
It is more important to focus on hand hygiene and other infection control measures.
Choice B rationale:
Restricting visitors strictly to immediate family members only is not necessary for a patient with MRSA.
While it is important to limit the number of visitors to reduce the risk of spreading infection, there is no need to restrict visitors to immediate family members only.
Visitors should be instructed on proper hand hygiene and other infection control measures, and they should avoid contact with the patient's wounds or dressings.
Choice C rationale:
Washing hands only after removing gloves post-care is not sufficient for preventing the spread of MRSA. It is important to wash hands before and after any contact with the patient, even when wearing gloves.
This is because gloves can become contaminated with bacteria, and hand washing helps to remove any bacteria that may have gotten on the hands.
Choice D rationale:
Preparing to administer vancomycin is the most appropriate action for a nurse caring for a patient with MRSA. Vancomycin is an antibiotic that is effective against MRSA.
It is often used to treat MRSA infections, and it can help to prevent the infection from spreading.

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.
