A nurse is caring for a client ordered ceftazidime 1g IM every 6 hours. The drug comes in a vial with a powder which is reconstituted with 3mL of sterile water for a final concentration of 280 mg/mL. How many mi. will be drawn into the syringe for the dose ordered? Do not use leading zero (Round to the tenth)

Given:

Desired dose: Ceftazidime 1 g IM every 6 hours

Available concentration: Ceftazidime 280 mg/mL

To find:

Volume to administer (in mL)

Step 1: Convert desired dose to milligrams

1 gram (g) is equal to 1000 milligrams (mg).

Multiply by 1000:

Desired dose (mg) = Desired dose (g) x 1000

Desired dose (mg) = 1 g x 1000 = 1000 mg

Step 2: Set up the proportion

We can use the following proportion to solve the problem:

(Desired dose) / (Available concentration) = Volume to administer

Step 3: Substitute the values

Plugging in the given values, we get:

(1000 mg) / (280 mg/mL) = Volume to administer

Step 4: Simplify

To simplify, we can invert the denominator and multiply:

(1000 mg) x (1 mL / 280 mg) = Volume to administer

The "mg" units cancel out, leaving us with:

(1000 x 1 mL) / 280 = Volume to administer

Step 5: Calculate

Performing the multiplication and division, we get:

1000 mL / 280 = Volume to administer

3.57 mL ≈ Volume to administer

Step 6: Round to the nearest tenth

3.6mL

• Apply petrolatum to penis with each diaper change: Applying petrolatum prevents the healing circumcision site from adhering to the diaper, reducing pain and promoting proper healing.
• Use a diaper barrier cream that contains zinc oxid: Zinc oxide is used for diaper rash treatment but is not routinely necessary. It may interfere with circumcision healing by creating a barrier that retains moisture.
• Use alcohol-based baby wipes on the soiled genital area: Alcohol-based wipes can be too harsh on a newborn’s delicate skin and may cause irritation, especially on the healing circumcision site.
• Fold the diaper below the umbilical cord at all times: Folding the diaper below the umbilical cord keeps the area dry and exposed to air, promoting natural drying and reducing the risk of infection.
• Apply alcohol to the umbilical stump with a diaper change: Alcohol was previously used to dry the cord, but current guidelines recommend keeping it clean and dry, allowing it to fall off naturally.
• Use a soft-bristled brush with mild shampoo to wash the head: A soft-bristled brush helps loosen cradle cap (seborrheic dermatitis), preventing buildup of flaky skin without causing irritation.
• Bathe in a shallow warm tub every other day: Full immersion bathing should be avoided until the umbilical cord stump falls off to prevent moisture retention and infection. Sponge baths are recommended instead.
• Cover the hands with socks or sleeves at all times: While covering hands temporarily can prevent scratches, prolonged covering may interfere with newborn sensory development and exploration.
• Apply mildly scented lotion to face as needed: Newborn skin is sensitive, and scented lotions may cause irritation or allergic reactions. If needed, only fragrance-free moisturizers should be used.
