A nurse is preparing regular and NPH insulin in the same syringe for a client who has diabetes mellitus. Which of the following actions should the nurse take?

Shake both insulin vials for 2 min before withdrawing the doses.

Administer the mixture within 5 min of preparing it.

Withdraw the NPH insulin before the regular insulin.

Inject air into the regular insulin vial before injecting air into the NPH vial.

Answer and Explanation

The Correct Answer is D

A. Shake both insulin vials for 2 min before withdrawing the doses. Insulin vials should never be shaken, as this can create air bubbles and affect dosage accuracy. NPH insulin should be gently rolled between the hands to mix.
B. Administer the mixture within 5 min of preparing it. While insulin should be administered promptly, there is no strict 5-minute requirement.
C. Withdraw the NPH insulin before the regular insulin. Regular insulin should be drawn up first to prevent contamination with the cloudy NPH insulin.
D. Inject air into the regular insulin vial before injecting air into the NPH vial. Air should be injected into the regular insulin first, then into the NPH insulin vial, before withdrawing the doses in the correct order.

Correct Answer is A

Explanation

A. "I can use chamomile tea to promote sleep." Chamomile has calming properties and is commonly used as a natural remedy to promote relaxation and improve sleep.
B. "Herbal medicines do not interact with conventional medications." Many herbs can interact with prescription medications, potentially causing harmful effects.
C. "I can use ginger to help treat headaches." Ginger is primarily used to reduce nausea and motion sickness rather than for headache relief.
D. "Herbal medicines are regulated by the Food and Drug Administration." Herbal supplements are not regulated by the FDA in the same way as prescription and over-the-counter medications.

A. Choose the client's dominant arm for IV access whenever possible. B. Select a site proximal to previous venipuncture sites. C. Initiate IV access on the palmar side of the client's wrist. D. Insert a larger gauge IV catheter to prevent phlebitis.

Correct Answer is B

Explanation

A. Choose the client's dominant arm for IV access whenever possible. The nondominant arm is preferred to minimize interference with daily activities.
B. Select a site proximal to previous venipuncture sites. This is the appropriate action because using a site above a previous one ensures better vein integrity and reduces complications.
C. Initiate IV access on the palmar side of the client's wrist. This site should be avoided as it is more painful and increases the risk of nerve damage.
D. Insert a larger gauge IV catheter to prevent phlebitis. A smaller gauge catheter is preferred when possible, as larger catheters can increase the risk of vein irritation and phlebitis.
