A nurse is educating a parent of a 6-month-old infant about car seat safety.
Which statement from the parent indicates a correct understanding of the teaching?

Choice A rationale

Metoclopramide is a medication used for stomach and esophageal problems. It is commonly used to treat and prevent nausea and vomiting, to help with emptying of the stomach in people

with delayed stomach emptying, and to help with gastroesophageal reflux disease. The antiemetic action of metoclopramide is due to its antagonist activity at D2 receptors in the chemoreceptor trigger zone in the central nervous system — this action prevents nausea and vomiting triggered by most stimuli.

Choice B rationale

While metoclopramide does have an effect on the muscles of the gastrointestinal tract, it does not work by relaxing them. Instead, it works by blocking dopamine receptors, which in turn stimulates motility in the upper gastrointestinal tract without stimulating gastric, biliary, or pancreatic secretions. This increased motility helps to speed up the rate at which the stomach empties into the intestines.

Choice C rationale

Metoclopramide does not work by decreasing gastric acid secretions. In fact, one unique property of this drug is that it does not increase gastric acid secretion. Its primary mechanism of action is to block dopamine receptors, thereby increasing muscle contractions in the upper digestive tract.

Choice D rationale

This is correct. Metoclopramide enhances gastric emptying. It is used to treat conditions like gastroesophageal reflux disease and diabetic gastroparesis, where delayed gastric emptying is a problem. By blocking dopamine receptors, metoclopramide increases muscle contractions in the upper digestive tract, speeding up the rate at which the stomach empties into the intestines.

Choice A rationale

Nausea and vomiting are common symptoms associated with migraines. Asking about these symptoms can help in assessing the severity of the migraine and planning appropriate interventions.

Choice B rationale

Sensitivity to light, also known as photophobia, is a common symptom of migraines. However, the presence of this symptom alone may not provide a comprehensive understanding of the patient’s condition.

Choice C rationale

While confusion or clouded thinking can occur with migraines, they are not as common as other symptoms such as nausea, vomiting, and sensitivity to light.

Choice D rationale

Feeling weak before the headache starts or currently feeling weak can be associated with migraines, but they are not the most common symptoms.
