    Donepezil, rivastigmine, and galantamine all...

    • Act as direct Ach agonists

    • Inhibit acetylcholine esterase

    • I don't care

    Correct Answer
    A. Inhibit acetylcholine esterase
    Explanation
    Donepezil, rivastigmine, and galantamine are all medications used in the treatment of Alzheimer's disease. They belong to a class of drugs called cholinesterase inhibitors, which means they work by inhibiting the enzyme acetylcholinesterase. Acetylcholinesterase is responsible for breaking down acetylcholine, a neurotransmitter involved in memory and cognition. By inhibiting this enzyme, these medications increase the levels of acetylcholine in the brain, which can help improve cognitive function in individuals with Alzheimer's disease. Therefore, the correct answer is that these medications inhibit acetylcholine esterase.

    This is the preferred antidepressant treatment for patients with AD

    • MAO-Is

    • SSRIs

    • TCAs

    • SNRIs

    Correct Answer
    A. SSRIs
    Explanation
    SSRIs, or selective serotonin reuptake inhibitors, are the preferred antidepressant treatment for patients with AD, which likely refers to Alzheimer's disease. SSRIs are commonly prescribed for depression, including in patients with AD, as they work by increasing the levels of serotonin in the brain. Serotonin is a neurotransmitter that plays a role in regulating mood, and by increasing its levels, SSRIs can help alleviate symptoms of depression. Other antidepressant classes like MAO-Is, TCAs, and SNRIs may also be used, but SSRIs are generally considered the first-line treatment due to their efficacy and favorable side effect profile.

    This barbiturate is used as a preventative treatment of seizures in children

    • Secobarbital

    • Phenobarbital

    • Pentobarbital

    Correct Answer
    A. Phenobarbital
    Explanation
    Phenobarbital is a barbiturate that is commonly used as a preventative treatment for seizures in children. It acts by suppressing abnormal electrical activity in the brain, thereby reducing the occurrence of seizures. This medication has been found to be effective in managing various types of seizures, including generalized tonic-clonic seizures and partial seizures. It is often prescribed for long-term use in children with epilepsy to help control and prevent seizures from happening. Phenobarbital has a long history of use and has been proven to be safe and effective in managing seizures in pediatric patients.

    Rate this question:

  • 11. 

    Your bipolar patient is acutely agitated and psychotic. What will you give them acutely so they calm the hell down?

    • Valproic acid

    • Benzodiazepine

    • Buproprion

    • 1st gen antipsychotic

    Correct Answer
    A. Benzodiazepine
    Explanation
    In a situation where a bipolar patient is acutely agitated and psychotic, the administration of a benzodiazepine would be the appropriate choice. Benzodiazepines are commonly used to manage acute agitation and anxiety due to their sedative and calming effects. They work by enhancing the effects of the neurotransmitter gamma-aminobutyric acid (GABA) in the brain, which helps to reduce excessive neuronal activity and promote relaxation. This can be particularly beneficial in managing acute episodes of agitation and psychosis in bipolar disorder. Valproic acid is primarily used as a mood stabilizer in bipolar disorder, while buproprion is an antidepressant and first-generation antipsychotics are typically not the first-line treatment for acute agitation in bipolar disorder.

  • 12. 

    2nd generation antihistamines work by blocking H1 receptors in the skin, vasculature, and CNS.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    2nd generation antihistamines do not work by blocking H1 receptors in the skin, vasculature, and CNS. Instead, they selectively target peripheral H1 receptors in the body, minimizing their penetration into the central nervous system (CNS). This reduces the risk of sedation and other central side effects commonly associated with 1st generation antihistamines. Therefore, the statement is false.

    What is raloxifene's MOA?

    • Directly decreases osteoclast activity

    • Raloxifene stimulates osteoblasts directly

    • Estrogen agonist/antagonist

    • Increases synthesis of vitamin D

    Correct Answer
    A. Estrogen agonist/antagonist
    Explanation
    Raloxifene's MOA is as an estrogen agonist/antagonist. This means that it acts as both an agonist and antagonist of estrogen receptors in different tissues. In some tissues, it acts as an agonist, mimicking the effects of estrogen, while in others it acts as an antagonist, blocking the effects of estrogen. This selective estrogen receptor modulator (SERM) activity allows raloxifene to have estrogen-like effects on bone, reducing bone resorption and increasing bone density, while also having anti-estrogenic effects on breast and uterine tissues, reducing the risk of breast cancer and endometrial hyperplasia.

    This OTC medication is recommended for patients with a productive cough

    • Benzonatate

    • Codeine

    • Dextromethorphan

    • Guaifenesin

    Correct Answer
    A. Guaifenesin
    Explanation
    Guaifenesin is recommended for patients with a productive cough because it is an expectorant. It helps to loosen and thin mucus in the airways, making it easier to cough up and clear the lungs. This can be beneficial for patients with a productive cough, as it helps to alleviate congestion and promote the removal of mucus from the respiratory system. Benzonatate is a cough suppressant, codeine is an opioid analgesic that can also suppress coughing, and dextromethorphan is another cough suppressant. These medications may be more appropriate for patients with a dry or non-productive cough.

    GABA is an excitatory CNS neurotransmitter 

    • True

    • False

    Correct Answer
    A. False
    Explanation
    GABA is actually an inhibitory neurotransmitter in the central nervous system (CNS). It works by reducing the activity of neurons and decreasing the likelihood of an action potential being generated. This inhibitory effect helps to regulate and balance the overall excitability of the brain. Therefore, the statement that GABA is an excitatory CNS neurotransmitter is incorrect.

    These two are first line TCAs due to their decreased risk of side effects

    • Desipramine

    • Amitriptyline

    • Nortriptyline

    Correct Answer(s)
    A. Desipramine
    A. Nortriptyline
    Explanation
    Desipramine and nortriptyline are considered first-line tricyclic antidepressants (TCAs) because they have a decreased risk of side effects compared to other TCAs. These medications are commonly used to treat depression and other mood disorders. By being first-line options, it means that they are often prescribed as initial treatment choices before other TCAs are considered. Their reduced side effect profile makes them more tolerable for patients and increases their overall safety.

    This med is indicated to relieve persistent ANS symptoms in patients with anxiety disorders.

    • Temazepam

    • Diazepam

    • Propanolol

    • Buspirone

    Correct Answer
    A. Propanolol
    Explanation
    Propanolol is the correct answer because it is a medication commonly used to relieve symptoms of anxiety disorders. It belongs to a class of drugs called beta blockers, which work by blocking the effects of adrenaline on the body's beta receptors. By doing so, propanolol helps to reduce the physical symptoms of anxiety, such as rapid heart rate, trembling, and sweating. It is often prescribed for patients with persistent autonomic nervous system (ANS) symptoms associated with anxiety disorders. Temazepam and diazepam are benzodiazepines used for treating insomnia and anxiety, while buspirone is an anti-anxiety medication.

    Rate this question:

    This sedative both potentiates the effects of GABA and acts as a direct GABA agonist.

    • Triazolam

    • Zolpidem

    • Chlordiazepoxide

    • Pentobarbital

    Correct Answer
    A. Pentobarbital
    Explanation
    Pentobarbital is the correct answer because it is a sedative that both enhances the effects of GABA (a neurotransmitter that inhibits brain activity) and directly activates GABA receptors. This dual action allows pentobarbital to effectively induce sedation and promote relaxation. Triazolam, zolpidem, and chlordiazepoxide may also have sedative effects, but they do not possess both potentiating and direct agonist actions on GABA receptors like pentobarbital does.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Antipsychotics are not an appropriate treatment for anyone with AD to treat aggression and hallucinations. While antipsychotics may be prescribed in some cases, they are not the first-line treatment and should be used with caution due to potential side effects. Other non-pharmacological interventions and medications may be more suitable and effective for managing aggression and hallucinations in individuals with AD.

    Rate this question:

  • 30. 

    Calcitonin activates Vitamin D

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Calcitonin does not activate Vitamin D. Calcitonin is a hormone released by the thyroid gland that helps regulate calcium levels in the blood by inhibiting the breakdown of bone tissue and promoting the excretion of calcium by the kidneys. Vitamin D, on the other hand, plays a role in calcium absorption in the intestines and bone health. It is activated by a series of steps involving the liver and kidneys. Therefore, the statement that calcitonin activates Vitamin D is false.

    This drug(s) have no risk of causing Serotonin Syndrome:

    • SSRIs

    • TCAs

    • Buproprion

    • Mirtazepine

    Correct Answer
    A. Buproprion
    Explanation
    Buproprion is the correct answer because it is an atypical antidepressant that does not significantly affect serotonin levels in the brain. Serotonin Syndrome is a potentially life-threatening condition that can occur when there is an excess of serotonin in the body. SSRIs and TCAs, on the other hand, are known to increase serotonin levels and therefore carry a risk of causing Serotonin Syndrome. Mirtazepine, although it does increase serotonin levels, has a lower risk of causing Serotonin Syndrome compared to SSRIs and TCAs.

    These benzodiazepines have significant CYP450 interactions

    • Diazepam

    • Oxazepam

    • Temazepam

    • Alprazolam

    • Midazolam

    • Triazolam

    Correct Answer(s)
    A. Diazepam
    A. Alprazolam
    A. Triazolam
    Explanation
    These three benzodiazepines, diazepam, alprazolam, and triazolam, have significant interactions with the CYP450 enzyme system. The CYP450 enzymes are responsible for metabolizing many drugs in the body. When these benzodiazepines are taken, they can inhibit or induce the activity of certain CYP450 enzymes, leading to altered metabolism of other drugs that are also metabolized by the same enzymes. This can result in drug interactions and potentially affect the efficacy or toxicity of the co-administered drugs. Therefore, it is important to monitor and adjust the doses of these benzodiazepines when used in combination with other medications.

    These are alterations in the CNS related to Alzheimer's: 

    • Overactivation of dopamine neurons

    • Degeneration of cholinergic neurons

    • Over activation of unregulated glutamate signaling

    Correct Answer(s)
    A. Degeneration of cholinergic neurons
    A. Over activation of unregulated glutamate signaling
    Explanation
    The correct answer is degeneration of cholinergic neurons and overactivation of unregulated glutamate signaling. In Alzheimer's disease, there is a progressive loss of cholinergic neurons in the brain, leading to a decrease in the neurotransmitter acetylcholine. This contributes to cognitive decline and memory impairment. Additionally, there is evidence of overactivation of glutamate signaling, which can lead to excitotoxicity and neuronal damage. These alterations in the CNS are characteristic of Alzheimer's disease.

    • TCAs

    • Oral decongestants

    • Caffeine

    • Corticosteroids

    • Mirtazepine

    • Parkinson's drugs

    Correct Answer(s)
    A. SSRIs
    A. Oral decongestants
    A. Caffeine
    A. Corticosteroids
    A. Parkinson's drugs
    Explanation
    The drugs that can cause insomnia are SSRIs, oral decongestants, caffeine, corticosteroids, and Parkinson's drugs. These medications can interfere with sleep patterns and disrupt the normal sleep-wake cycle, leading to difficulty falling asleep or staying asleep. Insomnia is a common side effect of SSRIs, which are a type of antidepressant. Oral decongestants, such as pseudoephedrine, can stimulate the central nervous system and cause sleep disturbances. Caffeine is a well-known stimulant that can keep individuals awake and prevent them from falling asleep. Corticosteroids, used to reduce inflammation, can also disrupt sleep patterns. Parkinson's drugs, which are used to manage symptoms of Parkinson's disease, can cause insomnia as a side effect.
