A nurse is educating a patient about SNRI antidepressant medication. What is a common side effect of SNRIs that the nurse should include in the teaching?

Choice A rationale:

The nurse should teach the patient to avoid foods rich in tyramine while on an MAOI antidepressant. MAOIs inhibit the enzyme monoamine oxidase, which breaks down tyramine in the body. Accumulation of tyramine can lead to hypertensive crisis due to excessive release of norepinephrine. Tyramine-rich foods include aged cheeses, cured meats, fermented foods, and certain beverages like wine and beer.

Choice B rationale:

The nurse should also teach the patient to avoid herbal supplements while on an MAOI antidepressant. Herbal supplements can interact with MAOIs and lead to potentially dangerous effects, including serotonin syndrome. Herbal supplements like St. John's wort, ginseng, and others may increase serotonin levels when combined with MAOIs.

Choice D rationale:

The nurse should instruct the patient to avoid over-the-counter pain relievers, particularly those containing pseudoephedrine or phenylephrine, while taking an MAOI antidepressant. These substances can also interact with MAOIs and result in hypertensive crisis due to increased release of norepinephrine.

Choice C rationale:

Choice C (Foods high in vitamin C) is not a concern when taking an MAOI antidepressant. Vitamin C-rich foods do not interact with MAOIs or pose a risk of hypertensive crisis. Thus, this choice is incorrect in the context of MAOI use.

Choice E rationale:

Choice E (Foods high in calcium) is also not a concern when taking an MAOI antidepressant. Calcium-rich foods do not have interactions with MAOIs that would result in hypertensive crisis. This choice is not relevant to MAOI medication.

Choice A rationale:

Benzodiazepines can cause weight gain and increased appetite. Rationale: This statement is incorrect. Benzodiazepines are not typically associated with weight gain and increased appetite. Weight gain is more commonly associated with certain other psychotropic medications like some antipsychotics and mood stabilizers. Benzodiazepines primarily affect the central nervous system and are known for their sedative and anxiolytic properties rather than influencing appetite.

Choice B rationale:

Benzodiazepines are used to enhance the effects of dopamine in the brain. Rationale: This statement is incorrect. Benzodiazepines do not enhance the effects of dopamine in the brain. They work by enhancing the inhibitory effects of the neurotransmitter gamma-aminobutyric acid (GABA), which leads to sedative and calming effects. Dopamine is a separate neurotransmitter associated with reward, motivation, and movement control, and benzodiazepines do not directly influence its effects.

Choice C rationale:

Benzodiazepines are commonly prescribed as mood stabilizers. Rationale: This statement is incorrect. Benzodiazepines are not commonly prescribed as mood stabilizers. Mood stabilizers are a class of medications used to manage mood disorders like bipolar disorder. While benzodiazepines might be used in certain cases to manage anxiety or agitation associated with bipolar disorder, they are not considered primary mood stabilizers. Mood stabilizers like lithium, anticonvulsants (e.g., valproate, carbamazepine), and certain atypical antipsychotics are more commonly used for this purpose.

Choice D rationale:

Benzodiazepines may lead to cognitive impairment and dependence. Rationale: This statement is correct. Benzodiazepines are associated with potential cognitive impairment and the risk of dependence. These medications have sedative effects that can impact cognitive function, including memory and attention. Prolonged use of benzodiazepines can lead to physical and psychological dependence, making it important for healthcare providers to carefully assess and monitor their use in patients, particularly those with bipolar disorder.
