Answer 1

The nurse should administer ceftazidime 1 g by intermittent IV bolus every 12 hr using the available ceftazidime injection 1 g in 0.9% sodium chloride (0.9% NaCl) 50 mL to infuse over 15 min.

Step-by-step explanation:

The prescribed dose of ceftazidime is 1 g to be administered every 12 hours. The available ceftazidime injection is in a 50 mL solution of 0.9% sodium chloride, and the infusion rate is specified to be over 15 minutes. To calculate the rate at which the nurse should administer the medication, we can use the formula:

`\[ Rate = (Volume)/(Time) \]`

Substituting the given values:

`\[ Rate = \frac{50 \, \text{mL}}{15 \, \text{min}} \]`

To make the units consistent, we can convert minutes to hours:

`\[ Rate = \frac{50 \, \text{mL}}{0.25 \, \text{hr}} \]`

Now, calculating the rate:

`\[ Rate = 200 \, \text{mL/hr} \]`

So, the nurse should administer ceftazidime at a rate of 200 mL/hr over 15 minutes every 12 hours. This ensures the prescribed dose is delivered within the specified time frame and follows the recommended infusion rate. Proper calculations and adherence to administration guidelines are crucial to ensure the patient receives the correct dosage in a safe and effective manner, minimizing the risk of complications.
