Patient Data
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.
No known allergies
Dosage in safe range
Potassium 4.4 mEq/L (4.4 mmol/L)
Peripheral IV in large vein
Used for prophylaxis
Blood urea nitrogen 17 mg/dl (6.07 mmol/L)
Correct Answer : A,B,D,E
Choice A: No known allergies
Reason: The absence of known allergies is crucial when administering any medication, including antibiotics like vancomycin. Allergic reactions to antibiotics can range from mild rashes to severe anaphylaxis, which can be life-threatening. In this case, the patient has reported no known allergies, which significantly reduces the risk of an adverse reaction to vancomycin. This makes it safer to proceed with the administration of the antibiotic. Ensuring that the patient has no known allergies is a standard precaution in medical practice to prevent potential allergic reactions.
Choice B: Dosage in safe range
Reason: The dosage of vancomycin must be within a safe range to avoid toxicity. Vancomycin is typically dosed based on the patient’s weight and renal function. For adults, the usual dose is 15-20 mg/kg, administered every 8-12 hours, depending on the severity of the infection and the patient’s renal function. In this scenario, the prescribed dose is 1 gram in 250 mL of 0.9% sodium chloride, which is within the safe range for an adult patient. Administering the correct dosage is essential to ensure the effectiveness of the antibiotic while minimizing the risk of nephrotoxicity and ototoxicity, which are potential side effects of vancomycin.
Choice C: Potassium 4.4 mEq/L (4.4 mmol/L)
Reason: While the potassium level of 4.4 mEq/L is within the normal range (3.5-5.0 mEq/L), it is not directly related to the safety of administering vancomycin. Potassium levels are more relevant to the overall electrolyte balance and cardiac function but do not specifically impact the administration of vancomycin. Therefore, this choice is not as pertinent to the safety of vancomycin administration as the other options.
Choice D: Peripheral IV in large vein
Reason: Administering vancomycin through a peripheral IV in a large vein is important to reduce the risk of phlebitis and irritation. Vancomycin is known to be irritating to veins, and using a large vein helps to dilute the medication more effectively, reducing the risk of vein inflammation. In this case, the peripheral IV was started in the right antecubital with a 20-gauge catheter, which is appropriate for the administration of vancomycin. Ensuring proper IV placement and using a large vein can help prevent complications associated with IV administration of this antibiotic.
Choice E: Used for prophylaxis
Reason: Vancomycin is being used as a prophylactic measure to prevent endocarditis in this patient. Prophylactic use of antibiotics is common in patients undergoing certain surgical procedures, especially those with a history of heart conditions, to prevent bacterial infections. In this case, the patient is undergoing pacemaker insertion, and the use of vancomycin as prophylaxis is appropriate to prevent potential infections. Prophylactic administration of antibiotics like vancomycin is a standard practice to reduce the risk of postoperative infections, particularly in patients with a higher risk of complications.
Choice F: Blood urea nitrogen 17 mg/dl (6.07 mmol/L)
Reason: The blood urea nitrogen (BUN) level of 17 mg/dL is within the normal range (7-20 mg/dL). While BUN levels are important indicators of renal function, they are not directly related to the safety of administering vancomycin in this context. Vancomycin dosing does need to consider renal function, but the BUN level alone does not provide sufficient information to determine the safety of administration. Therefore, this choice is not as directly relevant as the other options.

Correct Answer is B
Explanation
Choice A reason:
Performing a bladder scan is useful for assessing urinary retention, which can be a symptom of benign prostatic hyperplasia (BPH). However, it is not the primary method for monitoring adverse reactions to tamsulosin. Tamsulosin is an alpha-1 blocker that relaxes the muscles in the prostate and bladder neck, improving urine flow. While it can help reduce urinary retention, the primary concern with tamsulosin is its effect on blood pressure.
Choice B reason:
Monitoring blood pressure is crucial because tamsulosin can cause orthostatic hypotension, a condition where blood pressure drops significantly when a person stands up from a sitting or lying position. This can lead to dizziness, lightheadedness, and even fainting. Regular monitoring of blood pressure helps detect and manage this potential adverse reaction, ensuring the client’s safety.
Choice C reason:
Obtaining daily weights is important for monitoring fluid balance and detecting conditions like heart failure or kidney disease. However, it is not directly related to the adverse reactions of tamsulosin. The primary concern with tamsulosin is its impact on blood pressure, not fluid retention.
Choice D reason:
Assessing urine output is important for evaluating the effectiveness of tamsulosin in relieving urinary symptoms associated with BPH. However, it is not the primary method for monitoring adverse reactions. The main adverse reaction to be aware of with tamsulosin is its potential to cause orthostatic hypotension, making blood pressure monitoring the priority.
Correct Answer is D
Explanation
Choice A reason:
Requesting a prescription to change the route of administration and use the available heparin is not appropriate. Low molecular weight heparin (LMWH) and unfractionated heparin (UFH) are not interchangeable on a unit-for-unit basis. They have different pharmacokinetics and dosing requirements. Changing the route without proper guidance can lead to incorrect dosing and potential complications.
Choice B reason:
Calculating and administering the equivalent dose of the available low molecular weight heparin is incorrect. LMWH and UFH have different dosing protocols and are not directly interchangeable. Administering LMWH instead of UFH without proper conversion and guidance can result in inappropriate anticoagulation.
Choice C reason:
Diluting the available heparin in 250 ml of normal saline solution prior to IV administration is not appropriate. The prescription specifies heparin 5000 units IV STAT, which indicates an immediate need for intravenous administration. Diluting and administering it in this manner does not align with the urgency of the order.
Choice D reason:
Advising the pharmacy of the need to deliver a vial of heparin to the nursing unit immediately is the correct action. This ensures that the client receives the prescribed medication in the correct form and dosage as ordered by the healthcare provider. It is crucial to follow the specific instructions for heparin administration to ensure patient safety and effective anticoagulation.
