A nurse is preparing to administer haloperidol 75 mg IM per week. Available is haloperidol decanoate 100mg/ml for injection. How many ml should the nurse administer per dose? (Round the answer to the nearest hundredth. Use a leading zero if it applies.
The Correct Answer is ["0.75"]
To calculate the volume (ml) of haloperidol decanoate needed for a dose of 75 mg, you can use the following formula:
Volume (ml) = Dose (mg) / Concentration (mg/ml)
Given:
Dose = 75 mg
Concentration = 100 mg/ml
Plugging in the values:
Volume (ml) = 75 mg / 100 mg/ml
Volume (ml) = 0.75 ml
Rounding to the nearest hundredth:
Volume (ml) = 0.75 ml
So, the nurse should administer 0.75 ml of haloperidol decanoate for the dose of 75 mg.

Correct Answer is ["2"]
Explanation
To calculate the number of capsules that the nurse should administer per dose, the nurse should first divide the total daily dose of tetracycline by the number of doses per day. This gives the dose per administration:
2 grams / 4 doses = 0.5 grams per dose
Next, the nurse should convert the dose from grams to milligrams, since the available capsules are in milligrams. There are 1000 milligrams in one gram, so the nurse should multiply the dose by 1000:
0.5 grams x 1000 mg/g = 500 mg per dose
Finally, the nurse should divide the dose in milligrams by the strength of each capsule, which is 250 mg. This gives the number of capsules that the nurse should administer per dose:
500 mg / 250 mg/capsule = 2 capsules per dose
Therefore, the nurse should administer 2 capsules of tetracycline every 6 hours to the client.
Correct Answer is ["1.5"]
Explanation
To calculate the number of clozapine 200 mg tablets needed to administer a total of 300 mg, divide the total dose by the dose per tablet:
300 mg / 200 mg = 1.5 tablets
Since you cannot administer half of a tablet, you would need to administer 2 tablets to achieve a total of 300 mg.
So, the nurse should administer 2 tablets of clozapine 200 mg each to achieve a total dose of 300 mg.
