After administering propylthiouracil (PTU), what effect would the nurse anticipate the drug will have in the client’s body?
To suppress the hypothalamus’s production of thyrotropin-releasing hormone (TRH).
To suppress the anterior pituitary gland’s secretion of thyroid-stimulating hormone (TSH).
To inhibit production of thyroid hormone in the thyroid gland.
To destroy part of the thyroid gland.
The Correct Answer is C
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.

Correct Answer is A
Explanation
Phenothiazines are contraindicated in patients with suspected or established subcortical brain damage. Phenothiazines are a class of drugs that have antipsychotic, antiemetic, and sedative effects. They act by blocking dopamine receptors in the brain and can cause extrapyramidal symptoms, hypotension, and anticholinergic effects.
Choice B is wrong because phenothiazines are not contraindicated in patients with ischemic heart disease.
However, they can cause orthostatic hypotension and cardiac arrhythmias, so they should be used with caution and monitored closely in these patients.
Choice C is wrong because phenothiazines are not contraindicated in pediatric patients.
However, they can cause sedation, hypotension, and extrapyramidal symptoms, so they should be used with caution and at lower doses in these patients.
Choice D is wrong because phenothiazines are not contraindicated in patients with type 2 diabetes.
However, they can cause hyperglycemia and weight gain, so they should be used with caution and monitored closely in these patients.
Correct Answer is C
Explanation
This strategy can help the client read the numbers on the syringe and prepare the correct dose of insulin. A magnifying glass is also an affordable and accessible tool for the client.
Choice A is wrong because preparing a week’s supply of syringes and refrigerating them can affect the potency and sterility of insulin.
It can also increase the risk of errors or confusion.
Choice B is wrong because asking a neighbor to come over every day to prepare the medication can compromise the client’s privacy and independence.
It can also be unreliable and inconvenient for both parties.
Choice D is wrong because changing the client to oral antidiabetics is not possible for type 1 diabetes.
People with type 1 diabetes need to take insulin for life because their pancreas cannot make insulin.
Oral antidiabetics are only effective for people with type 2 diabetes who have functioning pancreatic beta cells
