Multiple Choice

Which action by the nurse ensures patient safety when administering an intramuscular injection?

Using the Z-track method to prevent medication leakage

Using a 25-gauge needle for all intramuscular injections

Choosing a site with visible veins for better absorption

Administering the injection at a 90-degree angle without aspiration

Verified step by step guidance

Understand the purpose of the Z-track method: The Z-track method is used to prevent medication leakage into subcutaneous tissues, which can cause irritation or reduce the effectiveness of the medication.

Identify the correct needle gauge: For intramuscular injections, typically a 22-25 gauge needle is used, but the choice depends on the medication and the patient's muscle mass. A 25-gauge needle may be too fine for some medications.

Select the appropriate injection site: Intramuscular injections should be given in areas with large muscle mass, such as the deltoid, vastus lateralis, or ventrogluteal sites, rather than sites with visible veins.

Determine the correct angle for injection: Intramuscular injections are typically administered at a 90-degree angle to ensure the medication is delivered deep into the muscle tissue.

Consider the need for aspiration: Aspiration is the process of pulling back on the syringe plunger to check for blood, indicating entry into a blood vessel. Current guidelines suggest that aspiration is not necessary for most intramuscular injections, but practices may vary.
