The nurse is caring for a client who developed hives after taking the first dose of a newly prescribed medication. How should the nurse interpret this finding?
The client experienced an adverse reaction.
The client experienced drug toxicity.
The drug produced a therapeutic effect.
The drug has not reached a steady state.
The Correct Answer is A
A. The client experienced an adverse reaction: Hives are a sign of an allergic or hypersensitivity reaction to the medication. This represents an unintended, harmful response that requires immediate attention, documentation, and potentially discontinuation of the drug.
B. The client experienced drug toxicity: Drug toxicity usually results from excessive dosing or accumulation, causing systemic effects. Hives alone are not indicative of toxicity but rather an immune-mediated reaction.
C. The drug produced a therapeutic effect: Therapeutic effects are the desired outcomes of a medication, such as symptom relief or disease control. Hives are an unwanted effect and do not indicate that the medication is achieving its intended purpose.
D. The drug has not reached a steady state: Steady state refers to the point at which drug intake and elimination are balanced. Hives are unrelated to steady-state pharmacokinetics and occur independent of plasma concentration.

Correct Answer is A
Explanation
A. Inhibits the synthesis of thyroid hormones: Methimazole is an antithyroid medication that works by blocking the thyroid gland’s ability to produce thyroxine (T4) and triiodothyronine (T3). By inhibiting hormone synthesis, it helps manage hyperthyroidism, reducing symptoms such as rapid heart rate, weight loss, anxiety, and heat intolerance, and preventing further complications.
B. Inhibits development of female sex hormones: Methimazole does not have any effect on estrogen, progesterone, or other female sex hormones. Its pharmacologic action is specific to thyroid hormone synthesis and does not influence reproductive hormone pathways.
C. Replaces endogenous thyroid hormones: Thyroid hormone replacement therapy, such as levothyroxine, is designed to supplement or replace deficient thyroid hormones in hypothyroidism. Methimazole does not replace hormones but instead decreases their production in hyperthyroid states.
D. Promotes development of female sex hormones: Methimazole does not stimulate or promote the production of any sex hormones. Its mechanism is limited to inhibiting thyroid hormone synthesis, and it has no role in reproductive hormone regulation.
Correct Answer is D
Explanation
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.
