Problem 88 - Cliffs Test Prep NCLEX-RN

Question

The physician orders furosemide (Lasix) 40 mg intravenous push times one dose for a patient in congestive heart failure. A drug reference states that the rate of administration should not exceed 5 mg per minute. Based on this reference, how long should it take the nurse to administer the furosemide? 1\. 5 minutes 2\. 40 minutes 3\. 8 minutes 4\. 20 minutes

Step-by-Step Solution

Answer

8 minutes

Step 1: Understand the Problem

The physician orders a 40 mg dose of furosemide to be administered intravenously. According to the guidelines, the administration should not exceed 5 mg per minute. We need to calculate how long it will take to administer 40 mg at this rate.

Step 2: Set Up the Equation

To find out the time it will take to administer the furosemide, we can use the formula: \( \text{Time (minutes)} = \frac{\text{Total Dose (mg)}}{\text{Rate (mg/minute)}} \). Our total dose is 40 mg, and we are administering at a rate of 5 mg per minute.

Step 3: Perform the Calculation

Substitute the values into the equation: \( \text{Time (minutes)} = \frac{40 \text{ mg}}{5 \text{ mg/minute}} \). Simplifying this expression gives: \( \text{Time (minutes)} = 8 \text{ minutes} \).

Step 4: Interpret the Result

The calculation shows that at a rate of 5 mg per minute, it would take the nurse 8 minutes to administer a 40 mg dose of furosemide.

Key Concepts

Medication Administration

Medication administration is a critical task performed by nurses and healthcare providers. It involves the process of giving medications to patients and ensuring the correct drug is delivered at the right time, dose, and method.
The process not only includes dispensing the medication but also assessing the patient's condition prior to administration. Nurses should review the physician's orders, verify the patient's identity, and consider factors like allergies or potential drug interactions.
In addition, proper documentation is essential. The nurse must accurately record each medication given, including the time, dosage, and any reactions.

• Ensure you understand the medication's purpose
• Check for any contraindications
• Follow the "Five Rights" of medication administration: right patient, right drug, right dose, right route, and right time

This vigilance helps maintain patient safety and prevents errors.

Dosage Calculation

Dosage calculation is an essential skill for nurses to provide safe and effective care. This involves calculating the right amount of medication the patient needs.
Typical calculations involve understanding prescriptions, converting units, and using formulas to ensure precise dosing.
The key to mastering dosage calculations is to familiarize oneself with basic mathematical operations and unit conversions.

• Assess the medication order and extract relevant numbers
• Convert units if necessary (e.g., mg to g, mL to L)
• Use the formula: \[ \text{Dose} = \left( \frac{\text{Desired dose}}{\text{Available dose}} \right) \times \text{Volume} \]

Accuracy in dosage calculation is crucial as even small errors can lead to adverse patient outcomes.

Intravenous Drug Administration

Intravenous (IV) drug administration is a common method used to deliver medications directly into a vein. This allows for rapid drug action and precise control over the drug's dosage and timing.
When administering IV drugs, it's essential to understand the specific guidelines for each medication, as the rate and method can vary significantly.
Furosemide, for example, should be administered slowly and carefully to avoid complications like ototoxicity. Nurses must be cautious to adhere to prescribed rates, as seen in the exercise where furosemide should not exceed 5 mg per minute.

• Confirm the IV site is patent and well-functioning
• Calculate the rate of administration using the formula: \[ \text{Time (minutes)} = \frac{\text{Dose (mg)}}{\text{Rate (mg/minute)}} \]
• Monitor for any signs of infiltration or adverse reactions

These steps are vital for safe and effective IV drug administration.

Patient Safety in Nursing

Patient safety is the cornerstone of nursing practice. It involves the prevention of harm to patients through both proactive measures and prompt response to issues.
In medication administration, patient safety is about ensuring the right drug is given under the right circumstances.
To reinforce safety, nurses should implement various strategies:

• Adhere to standardized protocols and procedures
• Engage in continuous education to stay informed about the latest practices
• Communicate effectively with both the healthcare team and patients

Regularly reviewing the steps for safe medication administration and remaining vigilant about potential side effects and reactions are fundamental practices to maintain patient safety.
The deliberate prevention of errors not only improves patient outcomes but also fosters trust and confidence in healthcare systems.
