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.
The Correct Answer is C
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 C
Explanation
This statement indicates that the patient understands the common side effect of codeine and how to prevent accidents while taking it.
Choice A is wrong because the patient should not take the medication anytime he starts to cough, but only as prescribed by the doctor.
Taking too much codeine can lead to overdose, addiction, or respiratory depression.
Choice B is wrong because this medication may not make the patient anxious and nervous, but rather sedated and relaxed.
Anxiety and nervousness are more likely to occur with decongestants, which are stimulants.
Choice D is wrong because diarrhea is not a common side effect of codeine.
In fact, codeine may cause constipation, so the patient should increase fluid and fiber intake while taking it.
Correct Answer is B
Explanation
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
