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 A

Explanation

This is because proton pump inhibitors (PPIs) are drugs that block the enzyme that produces hydrochloric acid in the stomach, thereby reducing the amount of acid secreted into the lumen. PPIs are commonly used to treat peptic ulcer disease and gastroesophageal reflux disease.

Choice B. Histamine-2 antagonist is wrong because histamine-2 antagonists (H blockers) are drugs that block the action of histamine on the parietal cells of the stomach, thereby reducing the amount of acid secreted into the lumen.

However, PPIs are more potent and effective than H blockers in suppressing acid secretion.

Choice C. Prostaglandin is wrong because prostaglandins are substances that protect the stomach lining from the damaging effects of acid and other factors.

Prostaglandins do not directly affect the secretion of acid into the lumen, but they may increase the production of mucus and bicarbonate that buffer the acid.

Choice D. Antipeptic agent is wrong because antipeptic agents are drugs that form a protective barrier over the ulcer crater, preventing further damage from acid and pepsin.

Antipeptic agents do not affect the secretion of acid into the lumen, but they may enhance healing by creating a favorable environment for tissue repair.

Normal ranges for hydrochloric acid secretion in the stomach are 1.5 to 3.5 liters per day, with a pH of 1.5 to 3.53.

A. Decrease in serum calcium and increase in serum phosphorous. B. Increase in serum calcium and decrease in serum phosphorous. C. Increase in serum calcium and phosphorous. D. Decrease in serum calcium and phosphorous.

Correct Answer is B

Explanation

This is because teriparatide affects calcium and phosphorus metabolism in a pattern consistent with the known actions of endogenous PTH (eg, increases serum calcium and decreases serum phosphorus)12.

Choice A is wrong because teriparatide does not decrease serum calcium, but increases it.

Choice C is wrong because teriparatide does not increase serum phosphorus, but decreases it.

Choice D is wrong because teriparatide does not decrease serum calcium, but increases it.

Normal ranges for serum calcium are 8.5 to 10.2 mg/dL and for serum phosphorus are 2.5 to 4.5 mg/dL.
