A nurse is preparing to administer nitroglycerin topical ointment to a client. Which of the following actions should the nurse plan to take?
Measure the dosage of medication using the applicator paper.
Spread the medication over a 12.7 cm (5 in) area of the client's skin.
Cover the medication on the client's skin with a sterile gauze pad.
Apply the medication to the same site for three consecutive days.
The Correct Answer is B
Choice A Reason:
Using the applicator paper is appropriate for measuring the dosage accurately, but simply measuring the dosage is not the only step; the medication needs to be spread over the specified area of the skin.
Choice B Reason:
Spread the medication over a 12.7 cm (5 in) area of the client's skin. Nitroglycerin ointment is typically measured using a specific paper or measuring tape provided with the medication to ensure accurate dosing. The ointment is spread thinly and evenly over a specific measured area of the skin, usually about 12.7 cm (5 inches) in length, to maintain consistent dosing.
Choice C Reason:
Covering the medication with a sterile gauze pad is not typically done with nitroglycerin ointment. The ointment is meant to be absorbed through the skin, and covering it may interfere with its absorption.
Choice D Reason:
Nitroglycerin ointment is often applied to different sites to prevent skin irritation and tolerance from developing at one site. It's usually rotated to different clean areas of the skin to prevent skin irritation and tolerance buildup. Applying it to the same site for three consecutive days is not standard practice.

Correct Answer is ["60"]
Explanation
Step 1: Determine the Lidocaine Concentration
- The solution contains 2 grams (2000 mg) of lidocaine in 500 mL.
- To find the amount of lidocaine per mL:
2000 mg ÷ 500 mL = 4 mg/mL
Step 2: Calculate the Total Dose per Hour
- The prescribed infusion rate is 4 mg per minute.
- In 1 hour (60 minutes), the total dose is:
4 mg/min × 60 min = 240 mg/hr
Step 3: Determine the Infusion Rate in mL/hr
- Since each mL contains 4 mg of lidocaine:
240 mg ÷ 4 mg/mL = 60 mL/hr
The nurse should set the IV pump to 60 mL/hr for the continuous IV infusion of lidocaine at a rate of 4 mg/min.
Correct Answer is C
Explanation
Choice A Reason:
INR (International Normalized Ratio) is incorrect. INR is a measurement used to monitor the effects of anticoagulants like warfarin. It assesses the blood's ability to clot. Filgrastim does not directly affect INR levels, so monitoring INR would not provide information about the effectiveness of filgrastim in stimulating white blood cell production.
Choice B Reason:
BUN (Blood Urea Nitrogen) is incorrect. BUN levels primarily indicate kidney function and hydration status. They are not directly influenced by filgrastim treatment. Monitoring BUN is essential for assessing kidney function but does not reflect the effectiveness of filgrastim therapy in increasing white blood cell counts.
Choice C Reason:
WBC count is correct. Filgrastim is a medication that stimulates the production of white blood cells (WBCs), particularly neutrophils. Therefore, the key laboratory value to monitor for assessing the effectiveness of filgrastim therapy is the WBC count. An increase in the WBC count, particularly in the neutrophil count, signifies the intended therapeutic effect of filgrastim in boosting the immune system's response by increasing the production of these infection-fighting cells.
Choice D Reason:
Potassium level is incorrect. Potassium levels are crucial for heart and muscle function. While certain medications might affect potassium levels, filgrastim's primary action is on stimulating white blood cell production and does not directly impact potassium levels. Monitoring potassium levels is essential for overall health but does not specifically indicate the effectiveness of filgrastim treatment.
