The nurse is working with a client who is newly diagnosed with hypothyroidism. Diagnostic testing has indicated that the client’s health problem is caused by anterior pituitary dysfunction.
This client’s hypothyroidism is rooted in a deficiency of:

tetraiodothyronine.

thyroid-stimulating hormone (TSH).

triiodothyronine.

Answer and Explanation

The Correct Answer is B

Thyroid-stimulating hormone - Wikipedia Thyroid-stimulating hormone (TSH) is a hormone produced by the anterior pituitary gland that stimulates the thyroid gland to release its own hormones, triiodothyronine (T) and thyroxine (T).12 If the anterior pituitary gland is dysfunctional, it will not produce enough TSH, leading to low levels of T and T. This condition is called secondary or pituitary hypothyroidism.123

Choice A is wrong because tetraiodothyronine is another name for thyroxine (T), which is a hormone produced by the thyroid gland, not the anterior pituitary gland.14

Choice C is wrong because triiodothyronine (T) is also a hormone produced by the thyroid gland, not the anterior pituitary gland.14

Normal ranges for TSH are 0.4 to 4.0 mIU/L, for T are 100 to 200 ng/dL, and for T are 4.5 to 11.2 mcg/dL.1

Correct Answer is C

Explanation

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.

Bismuth salts do not affect blood pressure or interact with antihypertensive medications.

A. 08:00. B. 22:00. C. 06:00. D. 16:00.

Correct Answer is C

Explanation

This is because cortisol exhibits a proper 24-h circadian rhythm that affects the cardiovascular system and other organs. Cortisol levels are normally low at the beginning of sleep and high at the moment of awakening. Taking corticosteroids at this time mimics the natural cortisol rhythm and may reduce side effects such as adrenal suppression, sleep disturbances and cardiovascular complications.

Choice A is wrong because taking corticosteroids at 08:00 may not coincide with the client’s natural cortisol peak and may cause insomnia or unpleasant dreams.

Choice B is wrong because taking corticosteroids at 22:00 may disrupt the client’s sleep quality and increase the risk of nocturnal hypertension.

Choice D is wrong because taking corticosteroids at 16:00 may interfere with the client’s natural cortisol decline and cause hyperglycemia or dyslipidemia.
