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
A. A 12-year-old child with obsessive-compulsive disorder is not typically a candidate for misoprostol, as it is not indicated for this condition.
B. A 46-year-old trial lawyer with hypertension might need caution when using misoprostol, as it can cause diarrhea and abdominal pain, which could be problematic.
C. An 83-year-old client with rheumatoid arthritis is the best candidate for misoprostol, particularly if they are taking nonsteroidal anti-inflammatory drugs (NSAIDs) for their condition. Misoprostol is often used to prevent NSAID-induced gastric ulcers in patients at high risk, such as elderly individuals or those with a history of ulcers.
D. A 22-year-old pregnant client should not be given misoprostol unless it is used for specific obstetric indications under close supervision. Misoprostol can induce uterine contractions and is contraindicated in pregnancy unless used for medical reasons like inducing labor or treating postpartum hemorrhage.
Correct Answer is C
Explanation
The nurse would assess these factors to determine the need for therapy. Some possible explanations for the other choices are:
Choice A. Number of times client’s family reports the client is nauseated.
This is not a reliable indicator of the severity or cause of nausea and vomiting.
The nurse should assess the client directly and not rely on the family’s reports.
Choice B. How well the client is eating.
This is not a specific or objective measure of nausea and vomiting.
The client may have other reasons for not eating well, such as loss of appetite, taste changes, or pain.
The nurse should also monitor the client’s weight, hydration status, and electrolyte levels.
Choice D. Client’s nutritional status and fluid balance.
These are important aspects of the client’s overall health, but they are not directly related to nausea and vomiting.
The nurse should assess these factors as part of the comprehensive care plan, but they are not sufficient to determine the need for therapy.
