Which of the following is a violation of safe practice when administering insulin?
Administering ordered insulin subcutaneously.
Using an insulin syringe to administer the insulin dose.
Drawing up the ordered dose in a 3 mL syringe.
Verifying the drawn-up insulin dose with another nurse.
The Correct Answer is C
Choice A rationale
Administering ordered insulin subcutaneously is the correct method of administration. Insulin is not typically given by other routes.
Choice B rationale
Using an insulin syringe to administer the insulin dose is the correct practice. Insulin syringes are calibrated in insulin units, which helps ensure accurate dosing.
Choice C rationale
Drawing up the ordered dose in a 3 mL syringe is a violation of safe practice. Insulin should always be drawn up in an insulin-specific syringe, which is marked in insulin units, not milliliters.
Choice D rationale
Verifying the drawn-up insulin dose with another nurse is a recommended safety practice in many settings. This double-check can help prevent errors in insulin dosing.

Correct Answer is A
Explanation
Choice A rationale
Cephalosporins are a class of antibiotics that are chemically related to penicillin. They have a similar mechanism of action and a similar core chemical structure. Because of these similarities, there is a risk of cross-reactivity between penicillins and cephalosporins, meaning that a person who is allergic to penicillin may also have an allergic reaction to cephalosporins.
Choice B rationale
Sulfonamides are a different class of antibiotics and do not have a chemical structure similar to penicillin. While a person could be allergic to both penicillin and sulfonamides, this would be due to two separate allergies, not a cross-reactivity.
Choice C rationale
Macrolides are another class of antibiotics that are not chemically related to penicillin. There is no known cross-reactivity between penicillin and macrolides.
Choice D rationale
Aminoglycosides are a class of antibiotics that are not chemically related to penicillin. There is no known cross-reactivity between penicillin and aminoglycosides.
Correct Answer is B
Explanation
Choice A rationale
While obtaining a blood pressure is an important part of overall patient assessment, it is not the priority action before administering antibiotics for a urinary tract infection.
Choice B rationale
Obtaining a urine specimen for culture and sensitivity is the priority action before administering antibiotics for a urinary tract infection. This allows for identification of the specific bacteria causing the infection and determination of the most effective antibiotic for treatment.
Choice C rationale
Obtaining a PTT (partial thromboplastin time) is not typically necessary before administering antibiotics for a urinary tract infection.
Choice D rationale
Obtaining a platelet count is not typically necessary before administering antibiotics for a urinary tract infection.
