The client is 8 weeks pregnant and requires an antithyroid medication.
The nurse identifies what drug as the drug of choice for this client?
Radioactive iodine.
Alendronate.
Propylthiouracil.
Methimazole.
The Correct Answer is C
This is an antithyroid medication that can be used safely during pregnancy, as it has a lower risk of causing birth defects or fetal hypothyroidism than other drugs. Propylthiouracil inhibits the synthesis of thyroid hormones and also blocks their conversion to the more active form.
Choice A is wrong because radioactive iodine is contraindicated during pregnancy, as it can cross the placenta and damage the fetal thyroid gland.
Radioactive iodine is used to destroy overactive thyroid cells and treat hyperthyroidism.
Choice B is wrong because alendronate is not an antithyroid medication, but a bisphosphonate that is used to treat osteoporosis and prevent bone loss.
Alendronate should not be used during pregnancy, as it may affect fetal bone development and mineralization.
Choice D is wrong because methimazole is another antithyroid medication, but it is not the drug of choice for pregnant women, as it has a higher risk of causing birth defects or fetal hypothyroidism than propylthiouracil.
Methimazole also inhibits the synthesis of thyroid hormones, but does not block their conversion to the more active form.

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 D
Explanation
This is because prednisolone can cause insomnia if taken later in the day, and it mimics the natural secretion of cortisol by the adrenal glands, which peaks in the morning.
Choice A is wrong because splitting the dose into two equal doses can increase the risk of adrenal suppression and reduce the efficacy of alternate-day therapy (ADT), which is used to minimize adverse effects of corticosteroids.
Choice B is wrong because taking prednisolone before bedtime can interfere with sleep and cause nocturnal cortisol secretion, which can lead to Cushing syndrome.
Choice C is wrong because taking prednisolone 1 hour before meals can cause gastric irritation and ulceration, and it is recommended to take it with food or milk.
