An accidental administration of a dose greater than recommended can result in toxicity. This means that the medication reaches harmful levels in the body and can cause damage to organs or other adverse effects.
Option A is incorrect because an overdose is more likely to increase side effects rather than decrease them.
Option B is incorrect because a lowered therapeutic threshold means that a lower dose of medication is needed to achieve the desired effect, which is not related to an overdose.
Option D is incorrect because an overdose can increase the effectiveness of the medication to dangerous levels, rather than decrease it.

The sudden development of hives in a client taking phenytoin is most likely an allergic response to the medication. In this case, the medication should be stopped and the healthcare provider should be notified.
Option A is incorrect because a paradoxical reaction is not related to the development of hives.
Option C is incorrect because an idiosyncratic reaction is unpredictable and can disrupt the treatment plan.
Option D is incorrect because a hypersensitive response would require more than just reducing the dose; the medication should be stopped.

Memantine is a medication used to treat moderate-to-severe Alzheimer's disease ¹². It works by reducing the actions of chemicals in the brain that may contribute to the symptoms of Alzheimer's disease ¹. While memantine can help slow the progression of Alzheimer's disease, it is not a cure and may not improve the condition ².

Option D is not correct because decreased anxiety and improved dietary habits are not specific therapeutic outcomes for risperidone in the treatment of schizophrenia.

A half-life is the time it takes for the concentration of a drug in the body to decrease by half. In this case, the medication has an 8-hour half-life, so after 8 hours, the concentration of the medication in the client's body would be reduced to 400mg (half of the initial dose of 800mg). After another 8 hours (16 hours total), the concentration would be reduced to 200mg. After another 8 hours (24 hours total), the concentration would be reduced to 100mg.

Diazepam is a benzodiazepine medication used to treat anxiety disorders. It works by enhancing the activity of certain neurotransmitters in the brain. A therapeutic outcome for this medication would be a decrease in anxiety and an improved ability to cope with stress.
Option B is not correct because it does not indicate whether the medication is effective or not.
Option C is not correct because it indicates that the client does not see a change in their symptoms.

Option B is not correct because the decision to stop a medication should be made by a healthcare provider based on an individual's response to treatment.
Option D is not correct because benzodiazepines are not intended for long-term use and should be used for the shortest possible time to achieve therapeutic goals ².

The half-life of a medication is the time it takes for the concentration of the medication in the body to decrease by half. In this case, the medication has a half-life of 2 hours and a current toxic level of 40 mEq/dL. After 2 hours, the level will decrease to 20 mEq/dL. After another 2 hours (4 hours total), the level will decrease to 10 mEq/dL, which is within the normal range. However, it will take another 21 half-lives (42 hours) for the level to reach 5 mEq/dL, which is the lower end of the normal range. Therefore, it will take a total of 25 hours (4 + 21) for the medication to reach the normal range.
Option B is incorrect because it would take much longer than 24 hours for the medication to reach the normal range.
Option C is incorrect because it would only take 2 hours for the medication to decrease by half, not reach the normal range.
Option D is incorrect because it would take longer than 4 hours for the medication to reach the normal range.

Carbidopa/levodopa is a medication used to treat the symptoms of Parkinson's disease, including tremors, stiffness, and difficulty with movement. If the medication is effective, the client should show improvement in their ability to move and perform daily activities.

Option A is incorrect because accelerated dementia would not cause the sudden onset of these symptoms.
Option B is incorrect because an infection would not explain the sudden onset of these symptoms after starting a new medication.
Option C is incorrect because aspiration would not cause rigidity or unstable blood pressure.

A selective serotonin reuptake inhibitor (SSRI) would be chosen as a first-line treatment option over a tricyclic antidepressant (TCA) for several reasons, including reducing the risk of suicide with overdose ³. TCAs have a higher potential for serious or fatal toxicity when taken in large amounts compared to SSRIs ³.
Option A is incorrect because SSRIs can cause sexual dysfunction as a side effect.
Option B is incorrect because both SSRIs and TCAs can cause weight gain and gastrointestinal (GI) effects.
