The client is a 75-year-old female admitted to the preoperative area to prepare for pacemaker insertion. Client reports she is having this done because her heart rate has been staying very low, she is always tired, and she has passed out once from low heart rate. Client has history of worsening symptomatic bradycardia. History of atrial fibrillation controlled. The nurse is preparing the client's plan of care. Select 4 findings that would indicate to the nurse that the administration of the vancomycin antibiotic would be safe to administer.

A. No known allergies:
Having no known allergies is a significant factor in determining the safety of administering vancomycin, as it reduces the risk of an allergic reaction. Vancomycin can cause allergic reactions or hypersensitivity, so it’s important to ensure the client is not allergic to this medication.

B. Peripheral IV in large vein:
Vancomycin should be administered through a large vein because it can be irritating to smaller veins and potentially cause thrombophlebitis or vein damage. Using a large vein helps to minimize these risks and ensure safe administration.

C. Potassium 4.4 mEq/L (4.4 mmol/L):
While potassium levels are important to monitor, they are not directly related to the safety of administering vancomycin. Vancomycin does not have a direct impact on potassium levels, so this finding does not specifically indicate the safety of vancomycin administration.

D. Used for prophylaxis:
Vancomycin is often used as prophylaxis in certain surgical procedures to prevent infection, especially in cases where there is a high risk of methicillin-resistant Staphylococcus aureus (MRSA) infection. The use of vancomycin for prophylaxis is a common practice and indicates it is being administered for an appropriate reason.

E. Blood urea nitrogen 17 mg/dL (6.07 mmol/L):
A blood urea nitrogen (BUN) level of 17 mg/dL is slightly elevated but not necessarily a contraindication for vancomycin administration. However, vancomycin can impact kidney function, so it is important to monitor renal function but not the sole factor in determining safety.

F. Dosage in safe range:
Ensuring the dosage of vancomycin is within the safe range is crucial for preventing toxicity and achieving therapeutic efficacy. This is an essential consideration when administering the medication to avoid adverse effects and ensure effective treatment.
