A nurse is preparing to administer cefazolin 500 mg IM to a client. Available is cefazolin powder 500 mg vial. After reconstitution, the concentration available is cefazolin 330 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation

The Correct Answer is ["1.5"]

The nurse should administer 1.5 mL of cefazolin solution.

Here's the calculation:

Desired dose: 500 mg

Concentration after reconstitution: 330 mg/mL

We can find the volume to administer by dividing the desired dose by the concentration and rounding to the nearest tenth:

Volume to administer (rounded to nearest tenth) = Dose / Concentration

= 500 mg / 330 mg/mL

= 1.5 mL (rounded to nearest tenth)

Therefore, the nurse should administer 1.5 mL of the reconstituted cefazolin solution.

Correct Answer is D

Explanation

A) As a square, white tablet:
The medication label indicates that furosemide 20 mg is a white, round tablet, not a square one. Therefore, this option is incorrect based on the label provided.

B) As a multicolored capsule:
The medication label specifies that furosemide 20 mg is a white, round tablet, not a multicolored capsule. Thus, this option does not match the description on the label.

C) With "Furosemide 20 mg" printed on one side of the capsule:
The label does not indicate that "Furosemide 20 mg" is printed on the medication. It describes the appearance as a white, round tablet with specific markings, but not with the dosage printed directly on it in this manner.

D) With "EP 116" stamped on one side of the tablet:
The label indicates that the furosemide 20 mg tablets are white, round tablets with "EP 116" stamped on one side. This option accurately matches the description provided on the medication label.

Correct Answer is ["1.9"]

Explanation

Here’s the calculation for your reference:

To find out how many mL the nurse should administer, we can use the formula:

Volumetoadminister= Doserequired/Concentrationavailable

Substituting the given values:

Volumetoadminister=187mg/100mg/mL =1.87mL

However, the question asks to round the answer to the nearest tenth. So, the nurse should administer 1.9 mL of Isoniazid
