The patient is a 75-year-old female who has been admitted to the preoperative area in preparation for pacemaker insertion.
She reports that she is undergoing this procedure because her heart rate has been consistently low, she feels constantly fatigued, and she has experienced one episode of fainting due to a low heart rate.
The patient has a history of progressively worsening symptomatic bradycardia and a history of atrial fibrillation, which is controlled by medication.
She has been off anticoagulants for four days in preparation for the procedure.
As the nurse prepares the patient’s plan of care, which four findings would indicate that it would be safe to administer the antibiotic vancomycin?
Potassium level is 4.4 mEq/L (4.4 mmol/L).
The antibiotic is being used for prophylaxis.
Blood urea nitrogen level is 17 mg/dL (6.07 mmol/L).
The dosage of the antibiotic is within the safe range.
The patient has no known allergies.
The patient has a peripheral IV in a large vein.
Correct Answer : A,B,C,E
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.

Correct Answer is B
Explanation
Choice A rationale
Osteoarthritis is a type of arthritis that occurs when the cartilage that cushions the ends of your bones in your joints gradually deteriorates. Osteoarthritis symptoms often develop slowly and worsen over time. They can include: Pain in the joint during or after use, or after periods of inactivity, Tenderness in the joint when you apply light pressure to or near it, Stiffness in the joint, that may be most noticeable when you wake up in the morning or after a period of inactivity, Loss of flexibility in the joint, Grating sensation or sound when you use the joint. But in this case, the client’s symptoms do not align with those of osteoarthritis.
Choice B rationale
Rheumatoid Arthritis is a chronic inflammatory disorder that can affect more than just your joints. In some people, the condition can damage a wide variety of body systems, including the skin, eyes, lungs, heart and blood vessels. Signs and symptoms of rheumatoid arthritis may include: Tender, warm, swollen joints, Joint stiffness that is usually worse in the mornings and after inactivity, Fatigue, fever and loss of appetite. The client’s symptoms align with those of Rheumatoid Arthritis.
Choice C rationale
Carpal Tunnel Syndrome is a condition that causes numbness, tingling and other symptoms in the hand and arm. Carpal tunnel syndrome is caused by a compressed nerve in the carpal tunnel, a narrow passageway on the palm side of your wrist. The anatomy of your wrist, health problems and possibly repetitive hand motions can contribute to carpal tunnel syndrome. But in this case, the client’s symptoms do not align with those of Carpal Tunnel Syndrome.
Choice D rationale
Gout is a common and complex form of arthritis that can affect anyone. It’s characterized by sudden, severe attacks of pain, swelling, redness and tenderness in the joints, often the joint at the base of the big toe. An attack of gout can occur suddenly, often waking you up in the middle of the night with the sensation that your big toe is on fire. The affected joint is hot, swollen and so tender that even the weight of the sheet on it may seem intolerable. But in this case, the client’s symptoms do not align with those of Gout.
Correct Answer is ["A","D"]
Explanation
Choice A rationale
A chest x-ray is a critical diagnostic tool for a patient presenting with flu-like symptoms, fever, chest congestion, and increased breathing difficulties. It can help identify conditions such as pneumonia or other lung diseases, which could be causing the patient’s symptoms.
Choice B rationale
While hydration is important, running a 0.9% sodium chloride IV infusion at 150 mL/hour is not the most immediate need for this patient. The patient’s symptoms are primarily respiratory, and there is no indication of dehydration.
Choice C rationale
A sputum culture could be useful for diagnosing bacterial infections of the respiratory tract. However, it is not the most immediate need for this patient, as the results of a culture test can take time to come back.
Choice D rationale
This is the correct answer. Given the patient’s increased breathing difficulties, starting oxygen therapy can help improve the patient’s oxygen levels and ease their breathing.
Choice E rationale
Starting a peripheral IV might be necessary for administering medications or fluids, but it is not the most immediate need in this scenario.
Choice F rationale
While controlling the patient’s fever is important, it is not as immediate a need as performing a chest x-ray and starting oxygen therapy.
