Question 1:

A nurse is preparing to administer haloperidol 5 mg IM to a client. Available is haloperidol 50 mg/mL. How many ml. should the nurse administer per dose? (Round the answer to the nearest tenth/whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation
Correct Answer: "5" mg

Explanation

To calculate the volume of haloperidol 5 mg to administer, we'll use the formula:
Volume (mL)=Dose (mg)/Concentration (mg/mL)
Given:
Dose = 5 mg
Concentration = 50 mg/mL
Plugging these values into the formula:
Volume (mL)=5 mg÷50 mg/mL
Volume (mL)=1÷10 
So, the nurse should administer 0.1 mL of haloperidol per dose.

Question 4:

A nurse is preparing to administer dexamethasone 3 mg PO. Available is dexamethasone 1.5 mg tablets. How many tablets should the nurse administer? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)

Answer and Explanation
Correct Answer: "2" tablets

Explanation

To calculate the number of dexamethasone 1.5 mg tablets needed to administer a 3 mg dose, we use the following formula:
Number of tablets=Dose (mg)÷Strength per tablet (mg)
Given:
Dose = 3 mg
Strength per tablet = 1.5 mg
Plugging these values into the formula:
Number of tablets=3 mg÷1.5 mg/tablet
Number of tablets=2
So, the nurse should administer 2 tablets of dexamethasone.
