A nurse is caring for a 1-month-old infant who weighs 3500 g and is prescribed a dose of cephazolin 50 mg/kg by intermittent IV bolus three times daily. How many mg should the nurse administer per dose? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero)

A. Take the medication with dairy products to increase absorption: Calcium carbonate antacids should not be taken with dairy products as they can reduce the absorption of calcium due to the formation of insoluble calcium salts. It's recommended to take calcium carbonate antacids between meals or with a light snack, but not with dairy products.
B. Decrease bulk in the diet to counteract the adverse effect of diarrhea: Calcium carbonate antacids can sometimes cause constipation rather than diarrhea. Increasing dietary fiber and fluid intake may help prevent constipation associated with the use of these antacids. Therefore, advising to decrease bulk in the diet is not appropriate.
C. Draw a glass of water after taking the medication: Calcium carbonate antacids should be taken with a full glass of water to ensure proper dissolution in the stomach and to prevent the risk of gastrointestinal irritation or obstruction. Water helps facilitate the dissolution and absorption of the medication, reducing the risk of adverse effects.
D. Reduce sodium intake: Calcium carbonate antacids may contain sodium, but reducing sodium intake is not a specific recommendation related to taking this medication. However, it's generally advisable to limit sodium intake for overall health, especially for individuals with conditions such as hypertension or heart failure.

Here's how we can find the desired flow rate:

1. Total volume to infuse (in minutes):
   • We need to convert the infusion time from hours to minutes.
   • Time (minutes) = Time (hours) x 60 minutes/hour
   • Time (minutes) = 2 hours x 60 minutes/hour
   • Time (minutes) = 120 minutes
2. Total volume to infuse (in mL):
   • Given volume = 250 mL
3. Drop factor (gtts/mL):
   • Given drop factor = 15 gtts/mL
4. Flow rate (gtts/minute):
   • Flow rate = Total volume (mL) / Time (minutes) x Drop factor (gtts/mL)
   • Flow rate = 250 mL / 120 minutes x 15 gtts/mL

To simplify the calculation, we can divide all values by 5 (as long as we perform the division on both sides of the equation, the answer won't change):

• Flow rate = (250 mL / 5) / (120 minutes / 5) x (15 gtts/mL / 5)
• Flow rate = 50 mL / 24 minutes x 3 gtts/mL
• Flow rate = 2.0833... gtts/minute (round to nearest whole number)

1. Rounded flow rate (gtts/minute):
   • Flow rate = 2 gtts/minute

Therefore, the nurse should adjust the flow rate to deliver approximately 2 gtts/minute.
