A nurse is caring for a client who is postoperative following arthroscopy and reports a pain level of 6 on a scale of 0 to 10 after receiving ketorolac 1 hr ago.
Which of the following actions should the nurse take?

Choice A rationale:

Injecting the medication at least 5 cm (2 in) from the umbilicus is not a standard guideline for IM injections. The site of injection depends on factors such as the volume of medication and patient’s age and muscle mass.

Choice B rationale:

Using the Z-track technique to administer the medication is correct. This technique helps to seal the medication in muscle tissue, reducing leakage into subcutaneous tissue.

Choice C rationale:

Giving the medication without aspirating prior to injection is not recommended. Aspiration ensures that the needle is not in a blood vessel before injecting.

Choice D rationale:

Administering the medication with a 27-gauge '/,-inch needle may not be appropriate for an IM injection, especially for adults. A longer and larger gauge needle is typically used for IM injections.

Choice A rationale:

Mixing insulin lispro and insulin glargine in the same syringe is not recommended. Insulin glargine has a different pH and mixing it with other insulins could affect its action.

Choice B rationale:

Insulin glargine is a long-acting insulin that is typically given once a day. It provides a steady level of insulin over a 24-hour period.

Choice C rationale:

Shaking insulin vials is not recommended as it can lead to inaccurate dosing. Instead, insulin vials should be gently rolled between the hands to ensure proper mixing.

Choice D rationale:

Insulin lispro is a rapid-acting insulin and should be taken right before a meal. This helps to control the blood glucose spike that occurs after eating.
