The nurse plans to assess the client for allergy to?
A.
Iodine.
B.
Latex.
C.
Shellfish.
D.
Sulphur.
The correct answer and Explanation is :
The correct answer is D. Sulphur.
Explanation
Thiazide diuretics, such as hydrochlorothiazide, are commonly prescribed for the management of hypertension. While assessing a client for allergies before administering this medication, it’s essential to consider the potential cross-reactivity and chemical composition of the drug.
Sulphur Allergies: Thiazide diuretics contain sulfonamide (sulfa) compounds. Although not all thiazide diuretics are sulfa-based, many have a similar chemical structure that can trigger allergic reactions in individuals with sulfonamide allergies. Patients who have a documented allergy to sulfonamides may experience skin rashes, hives, or even more severe reactions such as Stevens-Johnson syndrome or anaphylaxis when exposed to thiazide diuretics. Therefore, it’s critical to inquire about any history of sulfa allergies before starting the medication.
Other Allergies:
- Iodine: While iodine allergies are more pertinent when dealing with contrast agents used in imaging studies, they are not directly related to thiazide diuretics.
- Latex: Latex allergies pertain to rubber products and do not directly impact medication administration unless there are latex-containing products involved (e.g., gloves, catheters).
- Shellfish: Shellfish allergies are commonly associated with iodine sensitivity, particularly in the context of contrast dye, but they do not have a direct link to thiazide diuretics.
In conclusion, the most relevant allergy to assess for in clients prescribed thiazide diuretics is a sulfonamide allergy, making option D the most appropriate choice. This precaution helps prevent adverse reactions and ensures safe medication administration for clients with hypertension.
