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: Bone marrow transplant patients are immunocompromised; animals pose infection risks (e.g., zoonotic bacteria), making therapy contraindicated in this sterile setting.

Choice B reason: C. difficile is contagious; animal-assisted therapy risks cross-contamination via fur or handlers, endangering the patient and facility, ruling out this option.

Choice C reason: Acute asthma with dyspnea may worsen with animal dander triggering allergies or bronchospasm; therapy could exacerbate respiratory distress, making it unsuitable.

Choice D reason: Alzheimer’s patients benefit from animal therapy; it reduces agitation and boosts mood via oxytocin release, with no acute infection or allergy barriers.

A. 62.5 mL/hr B. 125 mL/hr C. 250 mL/hr D. 500 mL/hr

Correct Answer is A

Explanation

Choice A reason: Flow rate is volume divided by time; 250 mL over 4 hours equals 62.5 mL/hr, ensuring safe transfusion pacing to avoid fluid overload or hemolysis.

Choice B reason: 125 mL/hr assumes 250 mL over 2 hours; this doubles the ordered rate, risking circulatory overload and transfusion reactions in a standard protocol.

Choice C reason: 250 mL/hr infuses the unit in 1 hour; this rapid rate exceeds safe limits, potentially causing hypertension or pulmonary edema in vulnerable patients.

Choice D reason: 500 mL/hr is far too fast, implying 250 mL in 30 minutes; this dangerous speed could trigger severe hemolytic reactions or cardiovascular collapse.
