Calculate the flow rate in mL/hr. (The equipment used is programmable in whole mL/hr).
Order: 100 mL 0.45% NS in 45 minutes by infusion pump.
Calculate the rate in mL/hr.
145 mL/hr
133 mL/hr
125 mL/hr
135 mL/hr
The Correct Answer is B
To solve this problem, we need to use the formula:
Rate (mL/hr) = Volume (mL) / Time (hr)
Plugging in the given values, we get:
Rate (mL/hr) = 100 mL / 0.75 hr
Rate (mL/hr) = 133.33 mL/hr
However, this is not the final answer because the equipment used is programmable in whole mL/hr, which means we need to round the rate to the nearest whole number. Therefore, we need to apply the rounding rule: if the decimal part is 0.5 or more, round up; if the decimal part is less than 0.5, round down. In this case, the decimal part is 0.33, which is less than 0.5, so we round down. This gives:
Rounded rate (mL/hr) = 133 mL/hr
Therefore, the correct flow rate is 133 mL/hr.

Correct Answer is D
Explanation
To calculate the dosage using the ratio and proportion method, we can use the following formula: Dose on hand / Quantity on hand = Desired dose / X
Given that we have an order of Cialis tablets 15 mg p.o. daily and an available Cialis 5 mg scored tablet, we can calculate the number of tablets required as follows:
5 mg / 1 tablet = 15 mg / X
Cross-multiplying, we get:
5X = 15
Solving for X, we get:
X = 3
Therefore, the number of tablets required is:
Desired dose / Dose on hand = 15 mg / 5 mg = **3 tablets**
Since the available tablet is scored and has a strength of 5 mg, we can divide each tablet into two equal parts of 2.5 mg each. Therefore, the correct answer is **d) 1.5 tablets**.
