The nurse is initiating a prescription for Dextrose 2.5% in 0.45% Sodium Chloride (D2.5W, 0.45% NS) at 45 mL/hour for a child with dehydration. The nurse attaches a volume-control administration set with a microdrip chamber to the bag of solution. How many microdrops/minute should the nurse regulate the infusion? (Enter the numerical value only. If rounding is required, round to the nearest whole number.)

Answer and Explanation

The Correct Answer is ["45"]

To find the answer, we can use the following formula:

(microdrops/minute) = (mL/hour) x (microdrops/mL) / 60

Substituting the given values, we get:

(microdrops/minute) = (45) x (60) / 60

Simplifying, we get:

(microdrops/minute) = 45

Therefore, the nurse should regulate the infusion to deliver 45 microdrops/minute of Dextrose 2.5% in 0.45% Sodium Chloride.

Correct Answer is ["38.1"]

Explanation

To find the answer, we can use the following formula:

(Celsius) = (Fahrenheit - 32) x (5 / 9)

Substituting the given value, we get:

(Celsius) = (100.6 - 32) x (5 / 9)

Simplifying, we get:

(Celsius) = 68.6 x (5 / 9)

(Celsius) = 38.111

(rounded Celsius) = 38.1

Therefore, the nurse should document the oral temperature as 38.1 C in the medical record.

Correct Answer is ["1"]

Explanation

First, we need to find out how many mg of warfarin are in one vial. Since the vial is labeled 5 mg/single-use, we can assume that it contains 5 mg of warfarin.

Next, we need to find out how many mL of solution are in one vial. Since the instructions say to reconstitute with 2.7 mL of sterile water for injection to yield 2 mg/mL, we can use the following formula:

Amount of solution= amount of water + amount of warfarin

Substituting the given values, we get:

Amount of solution = 2.7 + 5 =7.7 mL

Now, we need to find out how many mL of solution contain 2 mg of warfarin, which is the prescribed dose for the patient. We can use the following formula:

mL of solution = mg of warfarin/ concentration of warfarin

Substituting the given values, we get:

mL of solution = 2/2 = 1 mL

Therefore, the nurse should administer 1 mL of solution to the patient.
