The nurse is caring for a client who has begun vomiting.
The nurse is aware that which part of the client’s brain has been stimulated?

Limbic system.

Hypothalamus.

Chemoreceptor trigger zone (CTZ).

Medulla oblongata.

Answer and Explanation

The Correct Answer is C

Pathophysiologic pathways involved in emesis - UpToDate

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.

A. tetraiodothyronine. B. thyroid-stimulating hormone (TSH). C. triiodothyronine.

Correct Answer is B

Explanation

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
