A nurse is teaching a client who has a new prescription for an antacid to treat a gastric ulcer. Which of the following statements by the client indicates an understanding of the teaching?

Choice A reason: This is incorrect. Taking an antacid with another antacid is redundant and unnecessary. Antacids are medicines that neutralize the acid in the stomach and relieve symptoms of heartburn, indigestion, and gastric ulcers. Taking too much antacid can cause side effects such as diarrhea, constipation, or electrolyte imbalance¹.

Choice B reason: This is incorrect. Taking an antacid as needed to reduce pain is not a good practice. Antacids are not painkillers and do not address the underlying cause of gastric ulcers. Gastric ulcers are sores in the lining of the stomach that can be caused by infection, inflammation, or erosion. Taking an antacid may temporarily relieve the pain, but it does not heal the ulcer or prevent complications. Antacids should be taken regularly as prescribed by the doctor, along with other medicines that treat the cause of the ulcer.

Choice C reason: This is correct. Taking an antacid after taking a proton pump inhibitor (PPI) is a good practice. PPIs are medicines that reduce the production of acid in the stomach and help heal gastric ulcers. However, PPIs may take several hours to work and may not provide immediate relief of symptoms. Taking an antacid after a PPI can help neutralize any remaining acid in the stomach and provide faster symptom relief. However, the antacid should be taken at least 2 hours after the PPI, as the antacid can interfere with the absorption of the PPI.

Choice D reason: This is incorrect. Reducing fluid intake with an antacid is not a good practice. Fluid intake is important for hydration, digestion, and elimination. Reducing fluid intake can cause dehydration, constipation, or kidney problems. Fluid intake does not affect the effectiveness of antacids, as long as the antacid is taken with a glass of water to help dissolve and flush it down the esophagus and into the stomach.

Choice A reason: Monoamine oxidase inhibitors (MAOIs) are not the correct class of medications to which escitalopram (Lexapro) belongs. MAOIs are a group of antidepressants that work by inhibiting the enzyme monoamine oxidase, which breaks down neurotransmitters such as serotonin, norepinephrine, and dopamine. MAOIs can increase the levels of these neurotransmitters in the brain and improve mood and energy. However, MAOIs can also cause serious side effects and interactions with other drugs and foods, and they are not commonly used as firstline treatment for depression. Escitalopram is not an MAOI, and it should not be taken with MAOIs or within 14 days of stopping or starting MAOIs, as this can cause a dangerous drug interaction called serotonin syndrome.

Choice B reason: Betablockers are not the correct class of medications to which escitalopram (Lexapro) belongs. Betablockers are a group of drugs that work by blocking the beta receptors on the heart and blood vessels, which are stimulated by adrenaline and noradrenaline. Betablockers can lower the heart rate, blood pressure, and cardiac output, and they are used to treat conditions such as hypertension, angina, arrhythmias, and heart failure. Betablockers can also reduce anxiety and tremors, but they are not antidepressants and they do not affect serotonin levels. Escitalopram is not a betablocker, and it does not have any significant effect on the cardiovascular system.

Choice C reason: Benzodiazepines are not the correct class of medications to which escitalopram (Lexapro) belongs. Benzodiazepines are a group of drugs that work by enhancing the activity of the neurotransmitter gammaaminobutyric acid (GABA), which has a calming and sedating effect on the brain. Benzodiazepines are used to treat anxiety, insomnia, seizures, and muscle spasms, and they can also cause relaxation, drowsiness, and amnesia. Benzodiazepines are not antidepressants and they do not affect serotonin levels. Escitalopram is not a benzodiazepine, and it does not have any significant effect on GABA receptors .

Choice D reason: Selective serotonin reuptake inhibitors (SSRIs) are the correct class of medications to which escitalopram (Lexapro) belongs. SSRIs are a group of antidepressants that work by blocking the reuptake of serotonin by the nerve cells, which increases the availability of serotonin in the synaptic cleft. Serotonin is a neurotransmitter that regulates mood, appetite, sleep, and cognition, and low levels of serotonin are associated with depression and anxiety. SSRIs can improve the symptoms of depression and anxiety by enhancing the serotonin signaling in the brain. Escitalopram is an SSRI, and it is used to treat major depressive disorder and generalized anxiety disorder.
