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?

A.

"Take five and a half tablets daily."

B.

"Take two and a half tablets daily."

C.

"Take five tablets daily."

D.

"Take two tablets daily."

Answer and Explanation

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 C

Explanation

the correct rate to administer the maintenance dose is 50 mL/hr.

Step 1: Determine the concentration of magnesium sulfate in the solution.

  • There are 40 grams of magnesium sulfate in 1 liter of solution.
  • 1 liter = 1000 mL.

Step 2: Calculate the concentration in grams per mL.

  • 40 grams ÷ 1000 mL = 0.04 grams per mL.
  • Result: 0.04 grams per mL.

Step 3: Determine the required dose per hour.

  • The physician ordered 2 grams per hour.

Step 4: Calculate the volume of solution needed to provide 2 grams of magnesium sulfate.

  • Required dose (2 grams) ÷ concentration (0.04 grams per mL) = volume in mL.
  • 2 grams ÷ 0.04 grams per mL = 50 mL.
  • Result: 50 mL.
  • The calculated rate is 50 mL/hr.

the correct rate to administer the maintenance dose is 50 mL/hr.

Correct Answer is A

Explanation

To find the rate in mL/hr, you need to calculate the following:

- The concentration of nitroglycerin in the IV solution in mcg/mL
- The infusion rate in mL/hr using the formula: Infusion rate (mL/h) = (Dose (mcg/min) x 60 min/h) / Concentration (mcg/mL)

First, convert the concentration of nitroglycerin from mg to mcg by multiplying by 1000:

125 mg x 1000 = 125,000 mcg

Then, divide the amount of nitroglycerin by the volume of the IV solution to get the concentration in mcg/mL:

125,000 mcg / 500 mL = 250 mcg/mL

Next, plug in the values into the formula for infusion rate:

Infusion rate (mL/h) = (42 mcg/min x 60 min/h) / 250 mcg/mL

Simplify and solve for the infusion rate:

Infusion rate (mL/h) = 10.08 mL/h

Therefore, the nurse should program the IV pump to deliver **10.1 mL/h** to infuse nitroglycerin at 42 mcg/minute.
