A client with type 2 diabetes presents at the clinic for a routine follow-up appointment. The client asks the nurse whether he or she can take the herbal supplement ginseng.
What is the correct response by the nurse?
“It increases the risk for low blood glucose levels.”.
“There is no reason ginseng cannot be taken by people with diabetes.”.
“There is no research to indicate what effect it will have.”.
“It increases the risk for high blood glucose levels.”.
The Correct Answer is A
Ginseng is a herbal supplement that may have some antidiabetic effects, such as improving glucose tolerance and insulin resistance. However, ginseng may also interact with certain diabetes medications, especially insulin and sulfonylureas, and cause hypoglycemia (low blood sugar)2. Therefore, the nurse should inform the client about this potential risk and advise them to consult their doctor before taking ginseng.
Choice B is wrong because there is a reason ginseng cannot be taken by people with diabetes without medical supervision.
As explained above, ginseng may lower blood glucose levels too much and cause hypoglycemia.
Choice C is wrong because there is some research to indicate what effect ginseng will have on diabetes.
Several studies have shown that ginseng may have beneficial effects on blood glucose control, but also some adverse effects such as hypoglycemia.
Choice D is wrong because ginseng does not increase the risk for high blood

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
Prednisone is a glucocorticoid that suppresses the production of natural cortisol by the adrenal glands. Taking prednisone on alternate days allows the adrenal glands to recover and produce some cortisol on the days without prednisone.
Choice B is wrong because prednisone does not eliminate adverse side effects, but may cause some such as weight gain, fluid retention, increased blood pressure, increased blood glucose, and increased risk of infection.
Choice C is wrong because there is no evidence of steroid tolerance, which means that higher doses are needed to achieve the same effect.
Choice D is wrong because prednisone does not prolong therapeutic effects, but may decrease them over time due to feedback inhibition of cortisol secretion.
Normal ranges for cortisol are 6 to 23 mcg/dL in the morning and 2 to 11 mcg/dL in the afternoon.
