How many milliliters per minute should the nurse administer to the patient?

A.

0.008 mL

B.

1 mL

C.

5 mL

D.

300 mL

Answer and Explanation

The Correct Answer is C

The patient is ordered to receive 5 mg of Lopressor over 60 seconds, which is equivalent to 1 minute. The concentration of Lopressor is 1 mg/1 mL, which means there is 1 mg of Lopressor in 1 mL of solution. To calculate how many milliliters per minute the nurse should administer, we can use the following formula:

5 mg / 1 mg per 1 mL = X mL X = 5 mL per minute.

Correct Answer is C

Explanation

To dilute the enteral feeding formula to half strength, we need to add an equal volume of water to the formula. Therefore, we need to add 250 mL of water to the 250 mL of full strength formula to make a total volume of 500 mL at half strength..

So the nurse should add 250 mL of water to the formula to dilute it to half strength.

Correct Answer is C

Explanation

A. 5ML: One tablespoon is equivalent to 15 milliliters, so 5 milliliters is too little for the prescribed dose.
B. 10ML: This amount is also insufficient, as it does not match the standard conversion of one tablespoon to milliliters.
C. 15ML: This is the correct conversion, as one tablespoon is equal to 15 milliliters.
D. 30ML: This amount is double the correct dose, which could lead to overmedication and potential side effects.
