Why is it important for drug labels to include warnings and contraindications?
They indicate the expiration date of the medication.
They list all possible side effects of the medication.
They help prevent administration to patients with potential risks.
They provide information on how to store the medication.
The Correct Answer is C
A. They indicate the expiration date of the medication: Expiration dates are included on labels but are separate from warnings and contraindications. They do not prevent unsafe administration to at-risk patients.
B. They list all possible side effects of the medication: Labels may include some side effects, but they do not typically list every possible reaction. Side effect information alone does not fully address patient safety concerning contraindications.
C. They help prevent administration to patients with potential risks: Warnings and contraindications identify conditions, allergies, or interactions that make the medication unsafe for certain patients. Including this information guides nurses and prescribers in preventing adverse events and ensuring safe administration.
D. They provide information on how to store the medication: Storage instructions are important for maintaining drug stability but are unrelated to preventing administration to patients at risk due to contraindications or warnings.

Correct Answer is D
Explanation
A. Use two separate syringes for each type of insulin to avoid errors: While using separate syringes is safe, premixed insulin injections are commonly prepared in one syringe to reduce the number of injections, provided proper technique is followed.
B. Mix both insulins together in the vial before drawing up the dose: Mixing insulins directly in the vial can alter their pharmacokinetics and is unsafe. Each insulin should be drawn carefully to maintain its intended action.
C. Withdraw 8 units of NPH insulin first, then 12 units of regular insulin into the same syringe: Drawing NPH first can contaminate the short-acting regular insulin with intermediate-acting insulin, affecting onset and duration and potentially leading to unpredictable blood glucose control.
D. Withdraw 12 units of regular insulin first, then 8 units of NPH insulin into the same syringe: Regular insulin (short-acting) should always be drawn first, followed by NPH insulin (intermediate-acting). This prevents contamination and maintains the correct pharmacokinetic profiles of both insulins.
Correct Answer is A
Explanation
Ordered Dose: 25 mg
Available Concentration: 50 mg/5 mL
- Calculate the volume to administer
Volume to administer = (Ordered Dose ÷ Concentration) × Volume of Concentration
Volume to administer = (25 ÷ 50) × 5
Volume to administer = 0.5 × 5
Volume to administer = 2.5 mL
