Why does the nurse administer lorazepam intramuscularly (IM) to the patient rather than into the subcutaneous tissue?
The patient does not have enough body fat to give the medication subcutaneously.
Intramuscular injections require smaller needles than subcutaneous injections.
The medication will be absorbed and begin to work more quickly when given IM.
Intramuscular injections are preferred for patients with a high risk of bleeding.
The Correct Answer is C
Choice A reason: Body fat levels influence subcutaneous absorption but are not the primary reason for choosing IM over SC injection in this scenario.
Choice B reason: Needle size varies by medication and patient factors, but this is not the defining reason for selecting IM over SC injection.
Choice C reason: IM injections deliver medication directly to muscle tissue with a rich vascular supply, ensuring faster absorption and onset compared to subcutaneous administration.
Choice D reason: IM injections are not inherently safer for patients at risk of bleeding; they carry similar risks and require proper assessment before administration.

Correct Answer is D
Explanation
Choice A reason: Administering insulin at proper timing correlates with mealtimes. However, this alone doesn't ensure safe practice.
Choice B reason: Confirming the injection site prevents lipodystrophy but does not address dose accuracy, which is vital for safety.
Choice C reason: Insulin is injected subcutaneously, not in the deltoid muscle. Using incorrect sites disrupts absorption.
Choice D reason: Double-checking insulin dose prevents administration errors, ensuring compliance with medication safety protocols.
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.
