The nurse explains that a drug may have several names. The trade name is the only name that can be:

Used by retailers to sell the drug.

Recognized as its chemical makeup.

Used in an order.

Trademarked.

Answer and Explanation

The Correct Answer is D

Choice A reason: Retailers use trade or generic names; trade isn’t exclusive here, as generics are sold too, making this a shared rather than unique trait.

Choice B reason: Chemical names define molecular structure (e.g., acetaminophen); trade names (e.g., Tylenol) are brand-specific, not tied to chemistry recognition.

Choice C reason: Orders use trade or generic names (e.g., Zestril or lisinopril); trade isn’t the only option, as generics are equally valid in prescriptions.

Choice D reason: Trade names are trademarked (e.g., Viagra); this legal protection distinguishes them from generic or chemical names, ensuring brand exclusivity.

Correct Answer is C

Explanation

Choice A reason: Body fat levels influence subcutaneous absorption but are not the primary reason for choosing IM over SC injection in this scenario.

Choice B reason: Needle size varies by medication and patient factors, but this is not the defining reason for selecting IM over SC injection.

Choice C reason: IM injections deliver medication directly to muscle tissue with a rich vascular supply, ensuring faster absorption and onset compared to subcutaneous administration.

Choice D reason: IM injections are not inherently safer for patients at risk of bleeding; they carry similar risks and require proper assessment before administration.

A. 90-degree B. 45-degree C. 15-degree D. 25-degree

Correct Answer is A

Explanation

Choice A reason: IM injections use a 90-degree angle; this ensures deep muscle penetration for average-weight adults, optimizing drug absorption into vascular tissue.

Choice B reason: 45 degrees is for subcutaneous injections; it’s too shallow for IM, risking fat deposition instead of muscle, reducing efficacy in this context.

Choice C reason: 15 degrees is far too shallow; it’s not a standard angle, likely depositing drug in skin layers, failing to reach muscle for intended absorption.

Choice D reason: 25 degrees mimics subcutaneous; it doesn’t reach muscle depth, compromising IM delivery and therapeutic effect in an average-weight client.
