Question

Quizplus · Accepted Answer

Subcutaneous injections are given in the adipose tissue layer under the skin, at a 45-degree angle for average-sized patients. Therefore, choice B is the best option. Choice A is incorrect because the deltoid muscle is not the site for subcutaneous injections. Choice C is incorrect because perpendicular positioning would result in an intradermal injection. Choice D is incorrect because a higher angle may result in intramuscular injection, which is deeper than subcutaneous.
