The healthcare provider prescribes metoclopramide 7.5 mg/mL IM every 3 hours PRN vomiting for a client who is receiving chemotherapy. The nurse prepares an injection using a 2 mL prefilled syringe cartridge labeled, "metoclopramide 5 mg/mL." How many mL should the nurse administer?
(Enter numeric value only. If rounding is required, round to the nearest tenth.)

Answer and Explanation

The Correct Answer is ["1.5"]

The correct answer is 1.5 mL. To find the answer, we can use the following formula:

(mL to be administered) = (mg prescribed) / (mg per mL)

Substituting the given values, we get:

(mL to be administered) = (7.5) / (5)

Simplifying, we get:

(mL to be administered) = 1.5

Therefore, the nurse should administer 1.5 mL of metoclopramide from the prefilled syringe cartridge to the client.

Correct Answer is ["2"]

Explanation

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

- Calculate the number of tablets needed to provide the prescribed dose of amoxicillin by dividing the dose in mg by the amount of amoxicillin in one tablet

- Calculate the number of tablets needed to provide the prescribed dose of clavulanate by dividing the dose in mg by the amount of clavulanate in one tablet

- Compare the two numbers and choose the larger one as the number of tablets to be administered

Using these steps, we get:

- (number of tablets for amoxicillin) = (2000) / (1000) = 2

- (number of tablets for clavulanate) = (125) / (62.5) = 2

- (number of tablets to be administered) = max(2, 2) = 2

Therefore, the nurse should administer 2 tablets of amoxicillin/clavulanate to the client.

Correct Answer is ["8.3"]

Explanation

The correct answer is 8.3 hours. To find the answer, we can use the following formula:

(hours) = (mL of IV) / (mL/hour)

Substituting the given values, we get:

(hours) = (500) / (60)

Simplifying, we get:

(hours) = 8.333

(rounded hours) = 8.3

Therefore, the IV should infuse for 8.3 hours.
