A client is receiving one liter of DW 0.45% normal saline IV every 8 hours by gravity infusion. The IV tubing has a drip factor of 12 gtt/mL. The nurse should regulate the IV to deliver how many drops per minute?
(Enter numeric value only. If rounding is required, round to the nearest whole number.)
The Correct Answer is ["25"]
To answer this question, we need to find the flow rate of the IV in milliliters per hour, and then multiply it by the drip factor of the IV tubing to get the drops per minute. The flow rate of the IV is the volume of fluid divided by the time of infusion, which is one
liter (or 1000 ml) divided by eight hours, or 125 ml/hour. The drip factor of the IV tubing is 12 gtt/mL, so the drops per minute are 125 x 12 / 60 = 25 gtt/minute. Therefore, the nurse should regulate the IV to deliver 25 drops per minute.

Correct Answer is ["15"]
Explanation
To answer this question, we need to convert the child's weight from pounds to kilograms, and then calculate the total daily dose and the dose per 12 hours. We also need to use the concentration of the amoxicillin suspension to find out how many mL correspond to the dose per 12 hours.
To convert pounds to kilograms, we divide by 2.2. So, 66 pounds / 2.2 = 30 kg. To calculate the total daily dose, we multiply the weight by the prescribed dose per kg. So, 30 kg x 80 mg/kg/day = 2400 mg/day.
To calculate the dose per 12 hours, we divide the total daily dose by 2. So, 2400 mg/day / 2 = 1200 mg/12 hours.
To find out how many mL correspond to the dose per 12 hours, we use the concentration of the suspension, which is 400 mg per 5 mL. We can set up a proportion as follows: 400 mg / 5 mL = 1200 mg / x mL. Solving for x, we get x = (1200 mg x 5 mL) / 400 mg = 15 mL.
Therefore, the nurse should administer 15 mL of amoxicillin suspension with each dose.
Correct Answer is ["9000"]
Explanation
calculate the bolus dose of Heparin, we need to multiply the prescribed dose per kg by the client's weight in kg. To convert pounds to kg, we divide by 2.2. In this case, the client's weight in kg is 198 / 2.2 = 90 kg. Therefore, the bolus dose of Heparin is 100 x 90 = 9000 units.
