A nurse is preparing to administer 0/9% sodium chloride (0.9% NaCl) 20ml/kg IV tp infuse over 6 hr to a school-age child who weighs 55 lbs. The nurse should set the IV pump to deliver how many ml/hr? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
8 mL/hr
8.3 mL/hr
83.3 mL/hr
83 mL/hr
The Correct Answer is D
Ordered dose of 0.9% Sodium Chloride: 20 mL/kg
Child's weight: 55 lbs
Infusion time: 6 hours
Step 1: Convert child's weight from pounds to kilograms:
1 pound (lb) = 0.453592 kilograms (kg)
Child's weight in kg = 55 lbs x 0.453592 kg/lb = 24.94756 kg
Step 2: Calculate the total volume of 0.9% Sodium Chloride:
Total volume (mL) = Ordered dose (mL/kg) x Child's weight (kg)
Total volume (mL) = 20 mL/kg x 24.94756 kg
Total volume (mL) = 498.9512 mL
Step 3: Calculate the infusion rate in mL/hr:
Infusion rate (mL/hr) = Total volume (mL) / Infusion time (hr)
Infusion rate (mL/hr) = 498.9512 mL / 6 hr
Infusion rate (mL/hr) = 83.15853333 mL/hr
Step 4: Round to the nearest whole number:
Infusion rate (mL/hr) ≈ 83 mL/hr

Correct Answer is D
Explanation
Given:
Ordered dose of clindamycin palmitate: 225 mg
Concentration of clindamycin palmitate oral suspension: 75 mg/5 mL
Step 1: Set up the proportion:
Desired dose (mg) / Volume to administer (mL) = Concentration (mg/mL)
Step 2: Substitute the values:
225 mg / Volume = 75 mg/5 mL
Step 3: Solve for the unknown volume:
Volume = 225 mg / (75 mg/5 mL)
Volume = 225 mg x (5 mL / 75 mg)
Volume = 15 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.
