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 C

Explanation

Choice A rationale
While lean beef, salads, and baked potatoes can be part of a balanced diet, they do not specifically target the prevention of colon and rectal cancers. Red meat, in particular, has been associated with an increased risk of colorectal cancer.
Choice B rationale
Potatoes, low-fat breads, and applesauce can be part of a balanced diet, but they do not specifically target the prevention of colon and rectal cancers. A diet rich in whole grains, fruits, and vegetables is more beneficial.
Choice C rationale
A diet rich in oatmeal, raisins, and fruit with skin is high in fiber and antioxidants, which can help reduce the risk of colon and rectal cancers. This is especially important for clients with a strong family history of these cancers.
Choice D rationale
Chicken, rice, and wheat products can be part of a balanced diet, but they do not specifically target the prevention of colon and rectal cancers. A diet rich in whole grains, fruits, and vegetables is more beneficial.

Correct Answer is ["0.4"]

Explanation

Step 1 is to determine the amount of penicillin in each milliliter (mL) of the available solution. The vial is labeled as “Penicillin 500,000 units/mL”.

Step 2 is to divide the prescribed dose by the concentration per mL. So, the calculation is 200,000 units ÷ 500,000 units/mL. The result is 0.4 mL.
