A patient is to receive insulin Regular and insulin NPH. How will the nurse draw up the insulins for administration?

Administer the two insulins using different syringes and different sites of the body.

Mix the Regular and NPH in the same syringe, drawing up the Regular first.

Shake the bottles vigorously before drawing up the insulins.

Mix the Regular and NPH in the same syringe, drawing up the NPH first.

Answer and Explanation

The Correct Answer is B

Choice A reason: Separate syringes increase injection sites and patient discomfort; mixing is standard as Regular and NPH are compatible, optimizing insulin delivery efficiency and absorption.

Choice B reason: Drawing Regular (clear) before NPH (cloudy) in one syringe prevents contamination of the short-acting vial with the intermediate-acting insulin, ensuring accurate dosing and stability.

Choice C reason: Shaking insulin damages its structure; NPH requires gentle rolling to mix, while Regular needs no mixing, making vigorous shaking inappropriate for preparation.

Choice D reason: Drawing NPH first risks contaminating the Regular vial with NPH particles, altering its rapid action; the clear-to-cloudy sequence maintains insulin integrity and efficacy.

Correct Answer is D

Explanation

Choice A reason: Removing in the medication room risks mix-ups; tablets could be dropped or misidentified before reaching the patient, compromising the three-check safety protocol.

Choice B reason: Outside the door is premature; without the patient present, verification against the MAR is incomplete, increasing error risk before final identity confirmation.

Choice C reason: At the cart is too early; medication stays packaged until bedside to ensure the right patient, right drug match, reducing handling errors or contamination.

Choice D reason: Bedside removal allows final MAR check with patient ID; it ensures accuracy, prevents mix-ups, and aligns with safety standards for administering oral medications.

A. An applicator B. An irrigation kit C. A finger D. A gauze pad

Correct Answer is A

Explanation

Choice A reason: An applicator ensures precise vaginal delivery; it maintains sterility, controls depth, and optimizes medication contact with mucosa for effective absorption.

Choice B reason: Irrigation kits are for flushing; they’re inappropriate for solid or cream medications, risking uneven distribution or mucosal irritation in the canal.

Choice C reason: A finger risks contamination; without sterile technique, it introduces bacteria, and depth control is poor compared to a designed applicator.

Choice D reason: Gauze pads can’t deliver deeply; medication may stick or distribute poorly, reducing efficacy and comfort in vaginal administration settings.
