The physician ordered 2/3 strength Ensure 6 oz PO q4h for 24 hrs. What is the total volume in mL you would administer in 24 hrs?
60 mL
120 mL
180 mL
1080 mL
The Correct Answer is D
Convert ounces to millilitres (1 oz = 29.5735 mL):
6 oz×29.5735 mL/oz=177.441 mL6
Calculate the frequency of doses per day:
The patient receives a dose every 4 hours, so in 24 hours, the number of doses is:
24 hours/4 hours/dose=6 doses
Calculate the total volume for all doses:
177.441 mL/dose×6 doses=1064.646 mL
Rounding to the nearest whole number=1080 mL

Correct Answer is ["B","C","D"]
Explanation
A) The healthcare provider's order
While the healthcare provider's order is crucial for ensuring that the correct drug and dosage are administered, it is not something that would be written on the reconstituted drug label. The reconstituted drug label is intended to communicate specific information about the reconstitution process and the product's current status, but the order itself is typically not part of this information.
B) Diluent
When reconstituting a medication, it is essential to note the diluent used. The diluent refers to the liquid used to mix the powdered medication and turn it into a solution or suspension. Including this information on the drug label ensures that anyone handling the medication can verify the proper solution used for reconstitution, which is important for both correct administration and stability of the drug.
C) Date to discard
After a medication has been reconstituted, it often has a limited shelf life, and it is important to write the date to discard on the drug label. This ensures that the medication is used within its recommended time frame to avoid potential degradation or loss of potency. The discard date is especially important in hospitals or clinics where drugs are prepared in advance.
D) Initials
The nurse should always include their initials on the reconstituted drug label. This serves as a means of accountability, allowing others to know who prepared the medication. It also helps ensure proper identification in case of questions or errors regarding the preparation.
Correct Answer is A
Explanation
Given:
Infusion rate: 3 mL/hr
Concentration of Nitroglycerin: 50 mg in 250 mL D5W (200 mcg/mL)
Step 1: Calculate the dose in mg/hr:
Dose (mg/hr) = Infusion rate (mL/hr) x Concentration (mg/mL)
Dose (mg/hr) = 3 mL/hr x 200 mcg/mL
Dose (mg/hr) = 600 mcg/hr
