The practical nurse (PN) is preparing cefazolin 400 mg IM for a client with a gram-positive infection. The available vial is labeled, "Cefazolin 1 gram," and the instructions for reconstitution state, for IM use, add 2 mL sterile water for injection. The total volume after reconstitution is 2.5 mL.

After reconstitution, how many mL should be administered to the client?

(Enter numeric value only. If rounding is required, round to the whole number, nearest tenths/hundredth).

Answer and Explanation

The Correct Answer is ["1"]

The concentration of cefazolin after reconstitution can be calculated as follows: Concentration = Total amount of drug / Total volume after reconstitution

Since the available vial contains 1 gram (1000 mg) of cefazolin and the total volume after reconstitution is 2.5 mL, we can calculate the concentration:

Concentration = 1000 mg / 2.5 mL = 400 mg/mL

Therefore, after reconstitution, the concentration of cefazolin is 400 mg/mL.

To administer a dose of 400 mg, we divide the desired dose by the concentration: Volume to administer = Desired dose / Concentration

Volume to administer = 400 mg / 400 mg/mL = 1 mL

Correct Answer is D

Explanation

Gently blowing the nose helps to clear any mucus or debris from the nasal passages, allowing for better delivery and absorption of the medication. It also helps to ensure that the nasal passages are clear and open, allowing the medication to reach its intended target.
A. Deep breathing and coughing are unrelated to the administration of nasal spray and are not necessary before using the medication.
B. Checking glucose levels before and after administration is not relevant for fluticasone furoate nasal spray. Glucocorticoid nasal sprays are not typically associated with significant effects on blood glucose levels.
C. Exhaling through the mouth is not a specific action required before using the nasal spray. It may be a general instruction for some other respiratory therapies or procedures, but it is not directly related to the administration of the nasal spray.

A. Apply gloves and empty the drainage bag. B. Remove the looped tubing from the bed. C. Measure the urinary output in the bag. D. Attach the drainage bag to the bed frame.

Correct Answer is D

Explanation

This is the action that the PN should implement when assessing a client with an indwelling urinary catheter and observing that the catheter drainage bag, which is half-full, is attached to the side rail and the tubing is looped on the bed. Attaching the drainage bag to the bed frame ensures that the bag is below the level of the bladder and prevents backﬂow of urine, which can cause infection or obstruction. The PN should also straighten the tubing and avoid any kinks or loops that may interfere with the drainage.
