A patient has an order for a subcutaneous injection of insulin. The nurse will prepare to give this injection into which of the following tissues?

Into the patient's vastus lateralis

Into the patient's deltoid

Into the patient's intravenous line

Into the fatty tissue of the patient's abdomen

Answer and Explanation

The Correct Answer is D

Choice A reason: Vastus lateralis is muscle; insulin given intramuscularly absorbs too fast, risking hypoglycemia, unlike the slower, safer subcutaneous route intended.

Choice B reason: Deltoid is also muscle; subcutaneous insulin isn’t given here as it’s not fatty enough, leading to unpredictable absorption rates versus abdominal tissue.

Choice C reason: Intravenous line is for IV drugs; insulin via IV is rare and only in emergencies, not standard subcutaneous orders, risking rapid overdose effects.

Choice D reason: Abdominal fat is ideal for subcutaneous insulin; it ensures steady absorption into capillaries, maintaining glycemic control per pharmacokinetic principles.

Correct Answer is D

Explanation

Choice A reason: Assuming patient preference lacks evidence; without asking, this dismisses autonomy, potentially misrepresenting the patient’s comfort with spiritual interventions.

Choice B reason: Endorsing without consent is inappropriate; the patient’s lack of affiliation suggests possible rejection, and this risks imposing unwanted religious activity.

Choice C reason: Doctor’s order isn’t required; prayer is a chaplain’s role, not medical, but patient consent is still needed, making this an unnecessary step.

Choice D reason: Permission respects autonomy; without religious affiliation, the patient may decline, and consent ensures ethical care aligned with individual beliefs.

A. 12-degree. B. 15-degree. C. 30-degree. D. 45-degree.

Correct Answer is B

Explanation

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.
