Cholestyramine should be taken with meals and water. The dosage should be administered once or twice daily, with a maximum of six times daily. Cholestyramine binds bile in the gastrointestinal tract to prevent its reabsorption.

There are many potential side effects of prednisone, including all those listed in the answer choices, headache, fatigue, acne, seizures, upset stomach, changes in mood, difficulty breathing, dry cough, vomiting, depression, heartburn, muscle weakness, irregular heart beat, tremors, inability to properly thermoregulate, and many others. 

The nurse must consider potential side effects of medications before administering them. Constipation, diarrhea, metabolic acidosis, and acid rebound are potential side effects of magnesium hydroxide. A dose of magnesium hydroxide may potentially exacerbate the patient’s current condition if he is constipated. As an antacid, magnesium hydroxide is indicated for peptic ulcers, stress ulcers, indigestion, and reflex esophagitis.

Fluoxetine is a selective serotonin reuptake inhibitor (SSRI) commonly prescribed to patients diagnosed with depression. It may cause changes in appetite and weight, increase anxiety and insomnia, or cause bradycardia or palpitations. It is most important for the nurse to educate the patient that the therapeutic effect of fluoxetine may take up to 4 weeks, as the patient has a previous suicide attempt, and may experience suicide ideation before the effect occurs.

Phenelzine is a monoamine oxidase inhibitor (MAOI) that treats depression. Patients who take MAOIs should avoid foods with tyramine due to an increased risk for hypertensive crisis. Tyramine-rich foods include those that are fermented, heavily marinated, pickled, smoked, or heavily marinated, also, chocolate and alcoholic beverages have significant amounts of tyramine. In addition to education about diet modification, nurses must educate patients of the signs of hypertensive crisis, which are headache, sweating, palpitations, stiff neck, and intracranial hemorrhage. All of the other listed patient educations are essential, but the priority is to avoid tyramine due to the risk for hypertensive crisis, which is life-threatening.

The only medication mentioned that does not actually stimulate insulin production is Metformin. This medication is a Biguanide, it's mechanism of action includes decreasing hepatic glucose production, and increases insulin sensitivity.

Terbutaline sulfate is a tocolytic agent, as well as a bronchodilator effective in stopping premature labor contractions. Both Pitocin and Misoprostol are used to induce labor, calcium gluconate in labor is used to reverse magnesium sulfate another tocolytic. Naprosyn is an NSAID. 

The correct answer is "Serotonin-norepinephrine reuptake inhibitor (SNRI)." This is correct because venlafaxine functions by blocking the reuptake of both serotonin and norepinephrine, and thus is classified as a serotonin-norepinephrine reuptake inhibitor (SNRI). Venlafaxine is used to treat a number of conditions including depression, anxiety, panic attacks, and social phobia, among others. In addition to its anti-depressant properties, it is also useful in that it can provide the benefit of increased energy in some patients due to the norepinephrine reuptake inhibition (effectively increasing the effect of norepinephrine). 

Selective serotonin reuptake inhibition (SSRI) is incorrect because venlafaxine is an SNRI, not an SSRI. An example of an SSRI is fluoxetine.

Monoamine oxidase inhibition (MAOI) is incorrect because venlafaxine is an SNRI, not an MAOI. An example of an MAOI is phenelzine. 

An example of a GABA agonist is phenobarbital, a barbiturate. 

An example of a beta-adrenergic blocker is propranolol.

The correct answer is "aged cheeses." This is the correct answer because MAOI's, when combined with food or drink products containing the metabolite, tyramine, have the potential to cause serious adverse effects including hypertensive crisis. Tyramine is found most commonly in aged cheeses and cured meats. Thus, since this patient is taking an MAOI, she should be advised to avoid aged cheeses.

Carrots, beets, grapefruit juice, and green, leafy vegetables do not need to be avoided in patients taking MAOI's. 

The correct answer is "Dopamine D2 receptor antagonist." 

This is the correct answer, as haloperidol is a first-generation antipsychotic, also known as a typical antipsychotic medication, and functions by selectively antagonizing dopaminergic D2 receptors. Haloperidol is used to treat a number of conditions including schizophrenia, bipolar disorder (manic phase), acute psychosis, tics from Tourette syndrome, and delirium, among others. 

Increased efficiency of GABA receptor binding describes the mechanism of action of benzodiazepines, not haloperidol.

Selective serotonin reuptake inhibition does not describe the mechanism of action of haloperidol. This describes medications like fluoxetine and escitalopram.

Serotonin-norepinephrine reuptake inhibition does not describe the mechanism of action of haloperidol. This describes medications like venlafaxine and desvenlafaxine.

Norepinephrine-dopamine reuptake inhibition does not describe the mechanism of action of haloperidol. This describes medications like buproprion and methylphenidate.
