A client with hypertension currently takes two and a half tablets of bisoprolol per day, each containing 100 mg. The new order is 500 mg of bisoprolol per day.
What instruction should be given to this client for the effective management of hypertension?
"Take five and a half tablets daily."
"Take two and a half tablets daily."
"Take five tablets daily."
"Take two tablets daily."
The Correct Answer is C
The instruction that should be given to this client for the effective management of hypertension is to take
**five tablets** of bisoprolol per day, each containing 100 mg.
This is because the new order of 500 mg of bisoprolol per day is twice as much as the current dose of 250 mg of bisoprolol per day (two and a half tablets of 100 mg each). Therefore, the client needs to double the number of tablets they take per day from two and a half to five.

Correct Answer is A
Explanation
To set the IV pump correctly, you need to calculate the following:
- The patient's weight in kilograms
- The dose of Zofran in milligrams
- The infusion rate in milliliters per hour
First, convert the patient's weight from pounds to kilograms by dividing by 2.2:
176 lb / 2.2 = 80 kg
Next, multiply the patient's weight by the dose of Zofran per kilogram to get the total dose in milligrams:
80 kg x 0.15 mg/kg = 12 mg
Then, use the formula for infusion rate to find how many milliliters per hour the IV pump should deliver:
Infusion rate (mL/h) = (Total volume (mL) x Flow factor (gt/mL)) / Time (min) x 60 min/h
Since the medication is mixed in 50 mL of normal saline and the infusion time is 15 minutes, plug in these values into the formula:
Infusion rate (mL/h) = (50 mL x 1 gt/mL) / 15 min x 60 min/h
Simplify and solve for the infusion rate:
Infusion rate (mL/h) = 200 mL/h
Correct Answer is A
Explanation
To find the total amount of heparin, you need to calculate the following:
- The concentration of heparin in units per milliliter
- The volume of heparin infused from 9:00 am to 11:00 am and from 11:00 am to 2:00 pm
- The amount of heparin in units from each time period and the total amount
First, divide the amount of heparin by the volume of D5W to get the concentration in units per milliliter:
25,000 units / 250 mL = 100 units/mL
Next, multiply the infusion rate by the duration to get the volume infused in each time period:
From 9:00 am to 11:00 am (2 hours), the infusion rate is 12 mL/hr:
12 mL/hr x 2 hours = 24 mL
From 11:00 am to 2:00 pm (3 hours), the infusion rate is 10 mL/hr:
10 mL/hr x 3 hours = 30 mL
Then, multiply the volume infused by the concentration to get the amount of heparin in units in each time period:
From 9:00 am to 11:00 am, the volume infused is 24 mL:
24 mL x 100 units/mL = 2400 units
From 11:00 am to 2:00 pm, the volume infused is 30 mL:
30 mL x 100 units/mL = 3000 units
Finally, add the amounts of heparin from each time period to get the total amount:
2400 units + 3000 units = 5400 units
Therefore, the patient received **5400 units** of heparin from 9:00 am to 2:00 pm.
