A patient is taking acetaminophen (Tylenol) 325 mg, 2 tablets PO every 6 hours. How many grams is the patient receiving in 24 hours?

(Number Only, do not type in gram or g with your answer)

The correct answer is choice B. Reduce gastric acid production.

Choice A rationale:

Preventing reflux is not the primary purpose of prescribing a histamine receptor antagonist. Histamine receptor antagonists work by reducing gastric acid production, which in turn can help alleviate symptoms of gastroesophageal reflux disease (GERD). They do not directly prevent the physical reflux of stomach contents into the esophagus.

Choice B rationale:

The primary purpose of prescribing a histamine receptor antagonist for an infant diagnosed with gastroesophageal reflux is to reduce gastric acid production. Histamine stimulates acid secretion in the stomach, and these medications (e.g., ranitidine, famotidine) block histamine receptors on stomach cells, leading to decreased acid secretion. This helps reduce the acidity of stomach contents that could contribute to esophageal irritation in GERD.

Choice C rationale:

Preventing hematemesis (vomiting blood) is not a primary action of histamine receptor antagonists. While reducing gastric acid production might indirectly help prevent complications such as bleeding due to irritation and inflammation of the esophagus, it's not the main purpose of these medications.

Choice D rationale:

Increasing gastric acid production is the opposite of the intended effect of histamine receptor antagonists. These medications are specifically used to decrease gastric acid production and provide relief from conditions where excess acid is causing problems, such as GERD.

The correct answer is choice C. Explain in simple terms how it works.

Choice A rationale:

Asking the girl why she wants to know might be appropriate in some contexts, but children are naturally curious and seeking information is a common behavior. Explaining how the blood pressure apparatus works would likely be more beneficial than questioning her motivation.

Choice B rationale:

Determining why she is anxious assumes that the girl is anxious, which might not be the case. Additionally, the question she asked does not necessarily indicate anxiety, but rather a curiosity about the medical equipment.

Choice C rationale:

Explaining in simple terms how the blood pressure apparatus works is the most appropriate nursing action. This approach respects the child's curiosity and provides her with age-appropriate information, fostering a positive and educational interaction.

Choice D rationale:

Telling her that she will see how it works as it is used might not fully satisfy her curiosity or address her immediate question. Children often benefit from clear and concise explanations, especially when it comes to medical equipment.
