Rheumatoid arthritis.
Viral gastroenteritis.

The Correct Answer is C
The nurse should question an order for bismuth salts for a client with an allergy to aspirin because bismuth salts contain salicylates, which are chemically related to aspirin and can cause allergic reactions.
Choice A is wrong because rheumatoid arthritis is not a contraindication for bismuth salts.
Bismuth salts may have anti-inflammatory effects that could benefit clients with rheumatoid arthritis.
Choice B is wrong because viral gastroenteritis is not a contraindication for bismuth salts.
Bismuth salts may help reduce diarrhea and inflammation caused by viral gastroenteritis.
Choice D is wrong because hypertension is not a contraindication for bismuth salts.

Correct Answer is A
Explanation
Levothyroxine is a synthetic form of thyroxine, the hormone that the thyroid gland normally produces.It is used to treat hypothyroidism by replacing the missing hormone and restoring the normal metabolism.
Some explanations for the other choices are:
• Choice B. Thyroid desiccated is a natural thyroid hormone derived from animal thyroid glands.
It contains both T4 and T3 hormones, which may cause side effects or complications in some people with hypothyroidism.It is not recommended as a first-line treatment for hypothyroidism.
• Choice C. Methimazole is an antithyroid drug that blocks the production of thyroid hormones.
It is used to treat hyperthyroidism, not hypothyroidism.Giving methimazole to someone with hypothyroidism would worsen their condition.
• Choice D. Liothyronine is a synthetic form of T3, the active thyroid hormone.
It is sometimes used in combination with levothyroxine to treat hypothyroidism, but it is not a standard treatment.It has a shorter half-life and more variable effects than levothyroxine, and it may increase the risk of cardiac arrhythmias or osteoporosis.
Normal ranges for thyroid function tests vary depending on the laboratory and the method used, but generally they are:
• TSH: 0.4 to 4.0 mIU/L
• Free T4: 0.8 to 2.0 ng/dL
• Free T3: 2.3 to 4.2 pg/mL
Correct Answer is C
Explanation
Propylthiouracil (PTU) is an antithyroid drug that blocks the synthesis of thyroid hormones by interfering with the oxidation of iodine and the coupling of iodotyrosines.
This reduces the levels of triiodothyronine (T) and thyroxine (T) in the blood and relieves the symptoms of hyperthyroidism.
Choice A is wrong because PTU does not destroy any part of the thyroid gland.
It only inhibits the production of thyroid hormones within the gland.
Choice B is wrong because PTU does not suppress the anterior pituitary gland’s secretion of thyroid-stimulating hormone (TSH).
TSH is a hormone that stimulates the thyroid gland to produce thyroid hormones.
PTU does not affect the feedback loop between the hypothalamus, pituitary, and thyroid glands.
Choice D is wrong because PTU does not suppress the hypothalamus’s production of thyrotropin-releasing hormone (TRH).
TRH is a hormone that stimulates the pituitary gland to secrete TSH.
PTU does not affect the feedback loop between the hypothalamus, pituitary, and thyroid glands.
Normal ranges for T are 80 to 220 ng/dL, for T are 4.5 to 11.2 mcg/dL, and for TSH are 0.4 to 4.0 mIU/L.
