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
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.
Correct Answer is C
Explanation
Choice A reason: An ID number alone lacks context; without name confirmation, it risks mismatching if wristbands are swapped, missing a critical identity check.
Choice B reason: Name alone may coincide with common names; without a unique identifier like a hospital number, this method risks errors in a busy unit.
Choice C reason: Name and hospital number provide dual identifiers; this matches the MAR precisely, ensuring accuracy for an unconscious patient per safety standards.
Choice D reason: Calling an unconscious patient is futile; they can’t respond, making this impractical and unreliable compared to objective wristband verification.
