The nurse is caring for a group of clients who have been prescribed insulin. For which client should the nurse withhold the prescribed dose of insulin?

A. "I will increase my dietary intake of iodine.": Methimazole works by inhibiting thyroid hormone synthesis, and increasing iodine intake may counteract its effects or worsen hyperthyroidism. Clients should avoid excessive iodine unless specifically directed by the provider.

B. "I will take my dose of medication with food.": Taking methimazole with food helps minimize gastrointestinal irritation, a common side effect. This demonstrates the client understands proper administration techniques to improve tolerance while maintaining therapeutic effectiveness.

C. "I will skip a dose if I experience palpitations.": Skipping doses without consulting the provider is unsafe, as inconsistent medication can worsen hyperthyroid symptoms and interfere with achieving a therapeutic effect. Palpitations should be reported, not treated by omission of the dose.

D. "My symptoms will improve within 24 hours.": Methimazole has a delayed onset of action; symptom improvement usually takes several weeks as thyroid hormone levels gradually decrease. Expecting immediate relief reflects a misunderstanding of the drug’s pharmacodynamics.

A. Identify the client using two identifiers: Client identification is a critical safety step prior to medication administration, not after the insulin has already been given. Performing this step post-administration does not enhance immediate safety or therapeutic monitoring.

B. Verify the insulin dose with another nurse: Dose verification is an essential safety measure before administration, especially with high-alert medications like insulin. After administration, verifying the dose again does not prevent adverse events that could occur from an incorrect dose already given.

C. Gently roll the vial between hands to mix: Mixing the insulin by rolling the vial is performed prior to drawing up the medication to ensure uniform concentration, not after injection. Post-administration rolling has no clinical benefit.

D. Continue to monitor the client for hypoglycemia: Monitoring for hypoglycemia is critical after administering rapid-acting insulin like lispro. Insulin lowers blood glucose quickly, and clients are at risk for symptoms such as sweating, shakiness, confusion, or seizures, making vigilant post-administration observation essential.
