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 B

Explanation

Choice A reason: 31 gtts/min assumes 250 mL over 4 hours with 15 gtts/mL; this halves the rate, underdelivering vancomycin, risking subtherapeutic levels and ineffective bacterial killing over the prescribed 2-hour infusion time.

Choice B reason: 62 gtts/min is correct; 250 mL over 2 hours is 125 mL/hr, times 15 gtts/mL equals 1875 gtts total, divided by 120 minutes yields 62 gtts/min, ensuring proper antibiotic delivery.

Choice C reason: 125 gtts/min doubles the rate; 250 mL in 1 hour with 15 gtts/mL is too fast, risking vancomycin toxicity, including renal damage, and exceeding safe infusion guidelines for IVPB.

Choice D reason: 250 gtts/min assumes 250 mL in 30 minutes; this dangerously rapid rate could cause vancomycin-induced red man syndrome or cardiovascular overload, far beyond the ordered 2-hour infusion duration.

A. After showing the drug label to the client B. Before returning the drug container to the client’s medication drawer C. Before calling the pharmacy D. After checking the drug container with a colleague

Correct Answer is B

Explanation

Choice A reason: Showing the client isn’t a standard check; patients don’t verify MAR, and this step lacks relevance to the nurse’s triple-check safety protocol.

Choice B reason: Checking before returning ensures accuracy; the third check confirms the right drug post-administration, completing the three-point verification process safely.

Choice C reason: Calling the pharmacy is unrelated; label checks occur during administration, not external consultation, making this an irrelevant timing option.

Choice D reason: Colleague checks aren’t routine; the three checks are individual, and this step doesn’t align with standard MAR verification timing protocols.
