CALCULATE FLOW RATE IN DROPS PER MINUTE:
Order: 1 L of 0.9% NS to infuse at 50 mL/hr.
Drop factor: 15 gtt/mL.
12 gtt/min
20 gtt/min
13 gtt/min
15 gtt/min
The Correct Answer is D
To calculate the flow rate in drops per minute, we can use the following formula:
Drops per minute = (Flow rate in mL/hour x Drop factor) / 60
Given that we have an order of 1 L of 0.9% NS to infuse at 50 mL/hr and a drop factor of 15 gtt/mL, we can calculate the flow rate as follows:
Drops per minute = (50 x 15) / 60 = **12.5 gtt/min**
Therefore, the correct answer is **d) 15 gtt/min**.

Correct Answer is D
Explanation
To calculate the dosage using the ratio and proportion method, we need to set up a proportion that compares the ordered dose to the available dose. In this case, we have an order of 1.0 g of Amoxil and capsules labeled 250 mg per capsule. We can use the formula:
ordered dose / available dose = x / 1 capsule
where x is the number of capsules to administer. We need to convert the units to the same ones, so we can change 1.0 g to 1,000 mg. Then we can plug in the values and solve for x:
1,000 mg / 250 mg = x / 1 capsule
Cross-multiply and simplify:
250x = 1,000
x = 1,000 / 250
x = 4
Therefore, the number of capsules to administer is 4.
Correct Answer is C
Explanation
To solve this problem, we need to find the infusion rate in ml/min by dividing the volume of the solution by the duration of the infusion. In this case, the infusion rate is:
100 ml / 60 min = 1.67 ml/min
Then, we need to multiply the infusion rate by the drop factor to find the flow rate in gtt/min. The drop factor is given as 10 gtt/ml. Therefore, the flow rate is:
1.67 ml/min * 10 gtt/ml = 16.7 gtt/min
However, since we cannot administer partial drops, we need to round the answer to the nearest whole number. The closest whole number to 16.7 gtt/min is 17 gtt/min, so we round up. Therefore, the flow rate in gtt/min is 17 gtt/min.
