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 C
Explanation
The nurse should question the administration of human insulin to this client because they do not need exogenous insulin to maintain normal blood glucose levels. Human insulin is indicated for clients who have type 1 diabetes or type 2 diabetes that cannot be controlled by oral antidiabetic agents, diet, or exercise.
Choice A is wrong because a client who has been diagnosed with gestational diabetes may need human insulin to control their blood glucose levels during pregnancy, as oral antidiabetic agents are contraindicated.
Choice B is wrong because a client with type 2 diabetes, controlled with oral antidiabetic agents, who has a systemic infection may need human insulin to manage their blood glucose levels during periods of stress, as infection can increase blood glucose levels and impair the action of oral antidiabetic agents.
Choice D is wrong because a client who has been living with type 1 diabetes for 20 years needs human insulin to replace the endogenous insulin that their pancreas cannot produce.
Correct Answer is D
Explanation
Oxygen cannot diffuse rapidly across the membrane to tissues in the eye. Diabetic retinopathy is caused by damage to the blood vessels of the retina, which is the light-sensitive tissue at the back of the eye. This damage can reduce the oxygen supply to the retina and lead to vision problems.
Choice A is wrong because cells in the eye can reproduce normally, but they may not function properly due to high blood sugar levels or lack of oxygen.
Choice B is wrong because diabetic retinopathy does not affect the production of aqueous humor, which is the fluid that fills the front part of the eye.
However, diabetes can cause another eye condition called glaucoma, which is caused by increased pressure from too much aqueous humor.
Choice C is wrong because diabetic retinopathy does not affect the nerve innervations throughout the eye.
However, diabetes can cause another eye condition called diabetic neuropathy, which is caused by damage to the nerves that control eye movement and pupil dilation.
