A client is prescribed a thiazide diuretic for the management of hypertension.
The nurse plans to assess the client for allergy to?
Iodine.
Latex.
Shellfish.
Sulphur.
The Correct Answer is D
Thiazide diuretics are sulfa-containing drugs and can cause allergic reactions in patients who are sensitive to sulfa compounds. These reactions can include headaches, rash, hives, swelling of the mouth and lips, wheezing or trouble breathing, asthma attack, and anaphylaxis.
Choice A is wrong because iodine is not a component of thiazide diuretics and is not related to sulfa allergy.
Choice B is wrong because latex is not a component of thiazide diuretics and is not related to sulfa allergy.
Choice C is wrong because shellfish is not a component of thiazide diuretics and is not related to sulfa allergy.
Shellfish allergy is usually caused by a protein called tropomyosin, not by iodine or sulfa compounds.
Thiazide diuretics are drugs that inhibit the reabsorption of sodium and water in the distal convoluted tubule of the kidney, leading to increased urine output. They are used to treat hypertension, edema, heart failure, and some kidney diseases. Some examples of thiazide diuretics are hydrochlorothiazide, chlorthalidone, and indapamide.

Correct Answer is D
Explanation
Alpha 1 adrenergic blocking agents have a vasodilating effect and can be used for the management of hypertension. They work by blocking the alpha 1 receptors on the vascular smooth muscle, which normally cause vasoconstriction when stimulated by catecholamines like epinephrine and norepinephrine.By preventing this constriction, alpha 1 blockers lower the peripheral resistance and blood pressure
Choice A is wrong because alpha 3 adrenergic blockers do not exist.There are only two types of alpha receptors: alpha 1 and alpha 2
Choice B is wrong because alpha 2 adrenergic antagonists do not have a vasodilating effect.
They block the alpha 2 receptors, which are located presynaptically on the sympathetic nerve terminals and postsynaptically on some vascular smooth muscle cells.Alpha 2 receptors inhibit the release of norepinephrine when activated, so blocking them would increase the sympathetic activity and vasoconstriction
Choice C is wrong because alpha 1 adrenergic agonists do not have a vasodilating effect.
They stimulate the alpha 1 receptors, which cause vasoconstriction and increase the blood pressure.Alpha 1 agonists are used to treat hypotension and nasal congestion
Correct Answer is B
Explanation
Diuretics are medicines that help the kidneys get rid of excess water and salt, which can ease the symptoms of heart failure, such as breathlessness and swelling.However, diuretics may also lower the blood pressure by reducing the blood volume and the cardiac output. This can cause symptoms such as dizziness, fatigue, or fainting.Hypotension is defined as a systolic blood pressure lower than 90 mmHg or a diastolic blood pressure lower than 60 mmHg.
Choice A is wrong because fluid retention is the opposite of what diuretics do. Diuretics increase the urine output and decrease the fluid accumulation in the body.
Choice C is wrong because hyperglycemia is not a common side effect of diuretics. Hyperglycemia is a condition where the blood sugar level is too high.Diuretics may affect the blood sugar level in some cases, but usually not significantly.
Choice D is wrong because diarrhea is not a typical side effect of diuretics.
Diarrhea is a condition where the stool is loose and watery.Diuretics may cause some gastrointestinal discomfort, such as nausea or cramps, but not diarrhea.
Normal ranges for blood pressure are 120/80 mmHg for systolic/diastolic in healthy adults, and 140/90 mmHg or higher for hypertension.Normal ranges for blood sugar are 70-100 mg/dL for fasting glucose, and less than 140 mg/dL for postprandial glucose.
