A patient with diabetic peripheral neuropathy has been taking pregabalin for the past four days. Which finding would indicate to the nurse that the medication is effective?

Choice A rationale
A potassium level of 4.4 mEq/L (4.4 mmol/L) is within the normal range. Potassium is a critical electrolyte in the body, playing key roles in cellular metabolism, protein synthesis, and electrical action potential regulation across cell membranes. Normal potassium levels typically range from 3.5 to 5.1 mmol/L1. Therefore, a potassium level of 4.4 mEq/L indicates that the patient’s potassium level is within the normal range, which is a safe condition for the administration of vancomycin.
Choice B rationale

The use of antibiotics for prophylaxis, or prevention, is a common practice in healthcare, particularly in surgical procedures such as pacemaker insertion. This is done to prevent potential infections that could occur during or after the procedure. Vancomycin is a type of antibiotic that is often used for prophylaxis against infections caused by gram-positive bacteria, including methicillin-resistant Staphylococcus aureus (MRSA)3. Therefore, if the antibiotic is being used for prophylaxis, it would be safe to administer vancomycin.
Choice C rationale
A blood urea nitrogen (BUN) level of 17 mg/dL (6.07 mmol/L) is within the normal range. The BUN test measures the amount of urea nitrogen in the blood, which can provide important information about kidney function. Urea nitrogen is a waste product that is created in the liver when protein is metabolized. It is then transported through the blood to the kidneys, which filter out most of the urea nitrogen, leaving a small amount in the blood. Normal BUN levels typically range from 6 to 20 mg/dL4. Therefore, a BUN level of 17 mg/dL indicates that the patient’s kidney function is within the normal range, which is a safe condition for the administration of vancomycin.
Choice E rationale
The absence of known allergies in a patient is a crucial factor in determining the safety of administering any medication, including vancomycin. Allergic reactions to medications can range from mild symptoms such as rash and itching to severe and life-threatening conditions such as anaphylaxis. Therefore, if a patient has no known allergies, it would be safe to administer vancomycin.
Choice D rationale

While it’s true that the dosage of the antibiotic should be within the safe range, the specific dosage of vancomycin for the patient isn’t provided in the question. Therefore, we cannot definitively say that this condition is met based on the information given.
Choice F rationale
Although vancomycin can be administered via a peripheral IV in a large vein, it’s important to note that vancomycin has a low pH and may cause venous irritation and tissue damage in cases of extravasation. Therefore, while it’s possible to administer vancomycin this way, it’s not necessarily an indicator of safety.

Choice A rationale

The unlicensed assistive personnel (UAP) is providing care to a client with influenza, a respiratory illness that can be transmitted through droplets when the client coughs or sneezes. Therefore, it is crucial for the UAP to wear a face mask while in close contact with the client to prevent the transmission of the virus. This is in line with the standard precautions for infection control, which recommend the use of personal protective equipment (PPE) such as gloves, gowns, and masks when providing care to clients with infectious diseases.
Choice B rationale
Reassigning the UAP to another client and assuming full care of the client is not the most appropriate action in this situation. While it is the nurse’s responsibility to ensure that the UAP is competent and understands the care needs of the client, it is not necessary to reassign the UAP unless there are specific concerns about their ability to provide safe and effective care.
Choice C rationale
While it is important for the UAP to alert the nurse of any changes in the client’s respiratory status, this is not the most immediate action that the nurse should take in this situation. The priority is to ensure that the UAP is wearing appropriate PPE to prevent the transmission of influenza.
Choice D rationale
A fitted respirator mask is typically used when caring for clients with airborne diseases, such as tuberculosis. Influenza is primarily spread through droplets, so a regular face mask is usually sufficient for protection.
