OB NURS 306 ATI REAL LIFE PREECLAMPSIA.
, ATI real life preeclampsia
Scenario
Nurse Morgan calculates the dosage of hydralazine (Apresoline).
Question
Nurse Morgan is preparing to administer hydralazine (Apresoline) 5 mg IV bolus. Available is
hydralazine 20 mg/mL. How many mL should Morgan administer? (Round the answer to the
nearest hundredth.)
Selected Option
0.25
Rationale
STEP 1: What is the unit of measurement to calculate?
mL
STEP 2: What is the dose needed? Dose needed = Desired.
5 mg
STEP 3: What is the dose available? Dose available = Have.
20 mg
STEP 4: Should the nurse convert the units of measurement?
No
STEP 5: What is the Quantity of the dose available?
1 mL
STEP 6: Set up the equation and solve for X.
Have = Desired
Quantity X
20 mg = 5 mg
1 mL X mL
X = 0.25
STEP 7: Round, if necessary.
STEP 8: Reassess to determine the amount to administer makes sense. If there are 20 mg/mL
and the amount prescribed is 5 mg, it makes sense to administer 0.25 mL. The nurse should
administer hydralazine 0.25 mL IV.
Nurse Morgan is preparing to administer magnesium sulfate IV at 2 g/ hr. Available is
magnesium sulfate 40 g/1,000 mL lactated Ringer's. Morgan should set the IV pump to deliver

Rationale

mL/hr
STEP 2: What is the volume needed?
2g
STEP 3: What is the total infusion time?
