When preparing to administer an intradermal injection to an adult, the nurse ensures that the dose amount does not exceed 0.1 mL. A 1 mL tuberculin syringe is used with a 25-gauge needle and is administered at which angle?
12-degree.
15-degree.
30-degree.
45-degree.
The Correct Answer is B
Choice A reason: A 12-degree angle is too shallow, increasing the risk of incorrect placement and ineffective administration of the intradermal injection.
Choice B reason: The 15-degree angle ensures precise intradermal placement, forming a wheal that indicates proper administration into the dermis for optimal absorption.
Choice C reason: A 30-degree angle places the medication too deep into subcutaneous tissue, compromising intended drug absorption.
Choice D reason: A 45-degree angle results in subcutaneous rather than intradermal injection, altering the drug’s effectiveness and purpose.

Correct Answer is B
Explanation
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: Juice may alter absorption; liquid can dilute or degrade some drugs, and taste may deter intake, reducing effectiveness compared to soft food.
Choice B reason: Applesauce masks taste and aids swallowing; it ensures crushed medication is consumed fully, maintaining dose integrity without altering pharmacokinetics significantly.
Choice C reason: Water may not mask bitterness; some drugs dissolve poorly or lose potency, and patients may not finish it, risking incomplete dosing.
Choice D reason: Meat or vegetables may bind drugs; uneven distribution or strong flavors could reduce intake, compromising the full therapeutic dose delivery.
