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: Half a tablet (10 mg) underdoses; expired drugs may degrade, and 40 mg is needed for diuresis, risking therapeutic failure in this scenario.

Choice B reason: Two tablets (40 mg) meet the dose but are expired; potency loss post-April 2013 risks inefficacy or toxicity, compromising patient safety.

Choice C reason: Seeking 40-mg tablets ignores expiration; even if available, current stock is outdated, and fresh supply is still required for reliable effect.

Choice D reason: Expired drugs (April 2013) lose potency; a new bottle ensures 40 mg of active furosemide, maintaining efficacy and safety for hypertension or edema.

A. Consult with the client's health care provider. B. Administer the liquid form of the drug. C. Administer the parenteral form of the drug. D. Crush the tablet before administration.

Correct Answer is A

Explanation

Choice A reason: Consulting ensures safety; not all drugs can be altered, and the provider adjusts the order, preventing errors in bioavailability or efficacy.

Choice B reason: Liquid may work, but without approval, it’s unauthorized; some drugs lack liquid forms, and this bypasses necessary prescriber oversight.

Choice C reason: Parenteral needs an order change; administering without it violates scope, and it’s invasive, escalating care unnecessarily as a first step.

Choice D reason: Crushing alters pharmacokinetics; many tablets (e.g., extended-release) can’t be crushed, and doing so without checking risks toxicity or inefficacy.
