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
The amount of ampicillin in one dose is 390 mg.
This answer is correct because it is based on a series of multiplication and division calculations. The nurse should follow these steps to determine the amount of ampicillin in one dose:
1) Multiply the prescribed dose per kilogram per day by the child's weight in kilograms to get the total dose per day in milligrams, as follows:
150 mg/kg/day x 10.4 kg = 1560 mg/day
Therefore, the child needs 1560 mg of ampicillin per day.
2) Divide the total dose per day by the number of doses per day to get the amount of each dose in milligrams, as follows:
1560 mg/day / 4 doses/day = 390 mg/dose
Therefore, the amount of ampicillin in one dose is 390 mg.
Correct Answer is C
Explanation
To answer this question, the nurse needs to perform the following steps:
1) Convert the patient's weight from pounds and ounces to kilograms, using the conversion factor of 1 pound = 0.45359237 kilograms¹². To do this, first convert the ounces to a fraction of a pound by dividing by 16, then add this fraction to the pounds, and then multiply by the conversion factor. For example:
7 lb, 11.2 oz = 7 + (11.2 / 16) lb
= 7.7 lb
= 7.7 × 0.45359237 kg
= 3.492 kg
2) Calculate the dose of Garamycin in milligrams, using the prescribed dose of 4 mg/kg and the patient's weight in kilograms. To do this, simply multiply the dose per kilogram by the weight in kilograms. For example:
4 mg/kg × 3.492 kg = 13.968 mg
3) Calculate the volume of Garamycin in milliliters, using the reconstituted dosage of 20 mg/10 mL and the dose in milligrams. To do this, use a proportion to find the unknown volume that corresponds to the known dose. For example:
20 mg / 10 mL = 13.968 mg / x mL Cross-multiply and solve for x: 20x = 139.68
x = 6.984 mL
x =7 mL
