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. Many of the herbal preparations are helpful primarily because of their placebo effect:
While placebo effects can play a role, many herbal preparations, including echinacea, have been studied for their potential therapeutic benefits beyond placebo effects. This statement oversimplifies and may dismiss valid efficacy.

B. This product is essentially harmless but also is not very beneficial in treating skin infections:
Echinacea is generally considered safe for topical use and has been used for various infections, including canker sores. This statement underestimates the potential benefits of echinacea in treating certain conditions.

C. Topical echinacea is usually used to soothe burns and can cause damage to the skin:
Topical echinacea is commonly used for various skin conditions, but it is not typically associated with causing skin damage. The statement may create unnecessary concern.

D. Echinacea seems to be useful in the treatment of some infections, such as canker sores:
Echinacea has been used traditionally and in some studies for its antimicrobial properties, which may be beneficial for certain infections, including canker sores. This statement acknowledges its potential utility without dismissing its benefits.

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.
