How many drops per minute should the nurse set for the infusion? The patient has been prescribed 1 liter of 0.9% sodium chloride, USP to be administered intravenously (IV) over a period of 4 hours.

The IV administration set delivers 10 drops/mL. If rounding is required, round to the nearest whole number.

Answer and Explanation

The Correct Answer is ["42"]

Step 1: Convert the volume from liters to milliliters. 1 liter = 1000 mL. Step 2: Convert the time from hours to minutes. 4 hours = 240 minutes.

Step 3: Calculate the rate in mL per minute. Rate = Volume ÷ Time = 1000 mL ÷ 240 min = 4.17 mL/min.

Step 4: Calculate the drops per minute. Drops per minute = Rate × Drop factor = 4.17 mL/min

× 10 gtt/mL = 41.7 gtt/min.

Step 5: Round off the result to the nearest whole number. 41.7 gtt/min rounds off to 42 gtt/min.

Correct Answer is D

Explanation

Choice A rationale
Antibiotics are typically used to treat bacterial infections, not fungal infections like athlete’s foot. Therefore, using antibiotics would not be effective in this case.
Choice B rationale
While it’s important to use treatments for the full recommended duration to ensure the infection is completely eradicated, using an antibiotic ointment for a fungal infection like athlete’s foot would not be effective.
Choice C rationale
While it’s true that applying too much ointment can deter its effectiveness, the main issue here is that an antibiotic ointment is not the correct treatment for a fungal infection like athlete’s foot.
Choice D rationale
Athlete’s foot is a fungal infection that thrives in warm, moist environments. Therefore, keeping the feet dry and clean is an important part of managing and preventing athlete’s foot. This includes wearing clean socks and allowing the feet to dry completely before putting on shoes.

A. Shoes should be worn outside the house, but it is fine to be barefoot inside. B. Family members can assist with regular foot exams. C. Heating pads are useful if used on the lowest setting. D. Aching feet may be soaked in lukewarm water for one hour or more.

Correct Answer is B

Explanation

Choice A rationale
While it’s important for patients with peripheral neuropathy to protect their feet, it’s recommended that they wear shoes at all times to prevent injury. Being barefoot, even inside the house, can increase the risk of foot injuries.
Choice B rationale
Regular foot exams are crucial for patients with peripheral neuropathy. Family members can assist with these exams, helping to identify any changes or injuries that may require medical attention.
Choice C rationale
Heating pads are not typically recommended for patients with peripheral neuropathy. Due to the loss of sensation in their feet, they may not realize if the pad is too hot, which could lead to burns.
Choice D rationale
Soaking feet in lukewarm water for extended periods is not typically recommended for patients with peripheral neuropathy. Prolonged exposure to water can dry out the skin and increase the risk of injury.
