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 B

Explanation

Choice A reason: Calling the name relies on response accuracy; confused or hearing-impaired patients may not answer correctly, risking misidentification and medication errors.

Choice B reason: Verbal confirmation plus armband verification against the MAR ensures identity via two identifiers, aligning with safety protocols to prevent administration errors scientifically.

Choice C reason: Family or visitors may misidentify due to stress or error; this lacks direct patient verification, increasing risk of giving medication to the wrong individual.

Choice D reason: Bed or door labels can be outdated or misplaced; this indirect method fails to confirm identity actively, heightening the chance of medication misadministration.

A. Patient with a history of alcohol abuse and hepatitis C B. Patient with COPD and a 20 pack-year history of smoking C. Patient with type 2 diabetes and end-stage renal disease D. Patient with prostate enlargement and urinary frequency

Correct Answer is A

Explanation

Choice A reason: Alcohol and hepatitis C impair liver function; acetaminophen’s metabolite NAPQI accumulates, causing hepatotoxicity in an already compromised organ.

Choice B reason: COPD and smoking affect lungs, not liver; acetaminophen metabolism is minimally impacted, posing lower hepatic risk compared to liver disease states.

Choice C reason: Renal disease affects drug excretion, not liver metabolism; acetaminophen’s hepatic load is unchanged, making liver damage less likely here.

Choice D reason: Prostate issues involve urinary tract; liver metabolism of acetaminophen remains intact, with no heightened risk of hepatotoxicity from this condition.
