A client is prescribed disulfiram. How does this medication assist the client in refraining from ingestion of alcohol?
Allows the accumulation of acetaldehyde
Decreases stimulation of the central nervous system (CNS)
Increases the level of acetylcholine d Increases the level of serotonin
The Correct Answer is A
Disulfiram is a medication used to treat alcohol use disorder (AUD). It works by inhibiting the enzyme acetaldehyde dehydrogenase, which is responsible for breaking down acetaldehyde, a toxic metabolite of alcohol. When alcohol is consumed while taking disulfiram, the accumulation of acetaldehyde in the body leads to unpleasant symptoms such as flushing, sweating, nausea, and vomiting. This creates an aversive reaction to alcohol consumption, which can help the client refrain from drinking.
The aversive effects of disulfiram can last for several hours to several days after alcohol consumption, depending on the dose of disulfiram and the amount of alcohol consumed. Therefore, it is important for clients taking disulfiram to avoid all sources of alcohol, including alcoholic beverages, mouthwash, and other products containing alcohol.
It is important to note that disulfiram is not a cure for AUD, and it works best when used as part of a comprehensive treatment plan that includes counseling and support. Disulfiram should only be used under the close supervision of a healthcare provider, as it can have serious side effects if used improperly.

Correct Answer is A
Explanation
A. An increase in serum lactate – This is a critical laboratory value that can indicate lactic acidosis, a serious side effect associated with metformin, especially in older adults or those with renal impairment. An increase in serum lactate necessitates discontinuation of the medication.
B. A decrease in hemoglobin and hematocrit – While this change may indicate anemia, it is not directly associated with the need to discontinue metformin. Further evaluation of the cause of anemia would be necessary.
C. An increase in white blood cells – This could indicate an infection or inflammatory process but does not specifically necessitate the discontinuation of metformin.
D. A decrease in potassium accompanied by an increase in sodium – While electrolyte imbalances should be monitored, this change does not directly indicate that metformin should be discontinued.
Correct Answer is A
Explanation
Hydrocortisone is a synthetic form of the hormone cortisol, which is produced by the adrenal glands. Addison's disease is a condition in which the adrenal glands do not produce enough cortisol and other hormones. Treatment with hydrocortisone is a lifelong therapy that replaces the missing hormones.
One of the potential adverse effects of long-term treatment with hydrocortisone is the development of sodium depletion or hyponatremia. This occurs because hydrocortisone can increase the excretion of sodium in the urine, leading to low levels of sodium in the blood.
To mitigate this potential adverse effect, the nurse should encourage the client to increase their intake of sodium. This can be done through dietary sources such as adding more salt to their food or drinking sports drinks that contain electrolytes. The client should also be monitored closely for signs of sodium depletion, such as weakness, fatigue, and confusion.
It is also important to note that long-term treatment with hydrocortisone can increase the risk of other adverse effects, such as osteoporosis, hyperglycemia, and infection. The nurse should educate the client on these potential adverse effects and encourage them to follow their healthcare provider's instructions for monitoring and management.
