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 CTZ has to be stimulated in order for vomiting to occur. The CTZ is located in the area postrema of the medulla oblongata and receives input from various sources, such as the blood, the vestibular system, and the gastrointestinal tract.
Choice A is wrong because the limbic system involves emotion, not vomiting or other forms of GI function.
Choice B is wrong because the hypothalamus regulates various functions such as body temperature, hunger, thirst, and circadian rhythms, but not vomiting.
Choice D is wrong because the medulla oblongata is responsible for autonomic functioning such as ventilation, cardiac conduction, and vomiting, but it is not the site of stimulation for vomiting.
The medulla oblongata contains the vomiting center, which receives signals from the CTZ and other sources and initiates the act of vomiting.
Correct Answer is A
Explanation
Diaphoresis means excessive sweating, which is one of the symptoms of hypoglycemia. Hypoglycemia occurs when the blood sugar level is lower than the normal range, which can cause dizziness, confusion, weakness, hunger, and other signs.
Choice B is wrong because flushing of the face is not a symptom of hypoglycemia.
Flushing can be caused by other conditions, such as fever, allergic reactions, or rosacea.
Choice C is wrong because fruity breath is a symptom of hyperglycemia, not hypoglycemia.
Hyperglycemia means high blood sugar level, which can cause the body to produce ketones that give the breath a fruity odor.
Choice D is wrong because unpredictable behaviors are not a specific symptom of hypoglycemia.
However, hypoglycemia can cause confusion, irritability, or anxiety, which may affect the behavior of some people.
The normal range of blood sugar level for most people is between 70 and 130 mg/dL (3.9 and 7.2 mmol/L) before meals and less than 180 mg/dL (10 mmol/L) after meals.
However, this may vary depending on the individual and the type of diabetes.
It is important to monitor the blood sugar level regularly and treat hypoglycemia promptly by eating or drinking a simple sugar source.
