A client with diabetes is scheduled for a CT scan of the abdomen with oral and IV contrast. Which medication would be of concern?

Choice A rationale:

Mixing insulins in a vial is generally not recommended unless specifically instructed by the healthcare provider. It can alter the effectiveness of the insulins and increase the risk of dosage errors.

Premixed insulins, which are already combined in a specific ratio, are available if a combination of insulins is needed.

However, in this case, the patient is instructed to administer regular and NPH insulin separately, indicating that they should not be mixed in a vial.

Choice B rationale:

Insulin can be injected into various subcutaneous sites, including the abdomen, thighs, upper arms, and buttocks.

There is no specific requirement to inject mixed insulin into the buttocks only.

The choice of injection site can be based on individual preferences, absorption rates, and the presence of lipohypertrophy (thickening of the subcutaneous tissue due to repeated injections).

Choice C rationale:

Drawing up NPH insulin first could lead to contamination of the regular insulin vial with NPH insulin.

NPH insulin is a suspension, and drawing it up first could introduce some of its particles into the regular insulin vial, potentially altering its absorption and action profile.

Choice D rationale:

It's crucial to draw up the regular insulin first to prevent contamination of the regular insulin vial with NPH insulin. The following steps outline the correct procedure:

Wash hands thoroughly with soap and water.

Inspect the insulin vials for clarity, expiration date, and any damage.

Roll the NPH insulin vial gently between the palms to resuspend the insulin particles (if applicable). Wipe the rubber stoppers of both vials with an alcohol swab.

Using a sterile syringe, withdraw air into the syringe equal to the amount of regular insulin to be drawn.

Inject the air into the regular insulin vial, keeping the needle tip above the fluid level to avoid creating bubbles. Invert the regular insulin vial and withdraw the prescribed dose of regular insulin.

Without injecting air into the NPH insulin vial, withdraw the prescribed dose of NPH insulin. Administer the insulin as directed, using proper injection technique.

Choice A rationale:

Stevens-Johnson syndrome (SJS) is a rare, serious skin condition that is typically caused by an allergic reaction to medication. While amiodarone has been associated with a few cases of SJS, it is not considered a common long-term side effect.

Choice B rationale:

Ventricular tachycardia (VT) is a type of fast heart rhythm that originates in the ventricles of the heart. Amiodarone is actually used to treat VT, so it would be counterintuitive to list it as a long-term side effect.

Choice C rationale:

Pulmonary fibrosis is a condition characterized by scarring of the lung tissue. While amiodarone can cause pulmonary toxicity, which includes pulmonary fibrosis, this is a relatively rare side effect. Moreover, it's usually associated with high doses or

long-term use of the medication.

Choice D rationale:

QT prolongation is a condition in which the heart's electrical activity takes longer than normal to recharge between beats. This can lead to a potentially fatal arrhythmia called torsades de pointes. Amiodarone is known to prolong the QT interval, and this is considered one of its most significant long-term side effects. It's important to monitor patients on amiodarone for QT prolongation and to adjust the dose or discontinue the medication if necessary.
