The nurse is caring for a client who works night shift from 22:00 to 06:00 and normally sleeps from 08:00 (8 AM) until 16:00 (4 PM) each day.
The nurse should teach this client to take the prescribed corticosteroid at what time of the day?
08:00.
22:00.
06:00.
16:00.
The Correct Answer is C
This is because cortisol exhibits a proper 24-h circadian rhythm that affects the cardiovascular system and other organs. Cortisol levels are normally low at the beginning of sleep and high at the moment of awakening. Taking corticosteroids at this time mimics the natural cortisol rhythm and may reduce side effects such as adrenal suppression, sleep disturbances and cardiovascular complications.
Choice A is wrong because taking corticosteroids at 08:00 may not coincide with the client’s natural cortisol peak and may cause insomnia or unpleasant dreams.
Choice B is wrong because taking corticosteroids at 22:00 may disrupt the client’s sleep quality and increase the risk of nocturnal hypertension.
Choice D is wrong because taking corticosteroids at 16:00 may interfere with the client’s natural cortisol decline and cause hyperglycemia or dyslipidemia.

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.
