What is the primary purpose of prescribing a histamine receptor antagonist for an infant diagnosed with gastroesophageal reflux?
Prevent reflux.
Reduce gastric acid production.
Prevent hematemesis.
Increase gastric acid production.
The Correct Answer is B
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.

Correct Answer is D
Explanation
The correct answer is choice E. Board games.
Choice A rationale:
Computer games might not be the best choice for a child with osteomyelitis. These games involve prolonged screen time and limited physical movement, which could potentially hinder the child's recovery.
Choice B rationale:
Paper and paints involve a level of physical activity that might not be suitable for a child with osteomyelitis. The child's movement might be restricted due to the condition, and activities that require fine motor skills might not be comfortable for them.
Choice C rationale:
Jack-in-the-box involves sudden surprises and might startle the child, which could be detrimental to their recovery. Children with osteomyelitis might be dealing with pain and discomfort, so it's important to avoid activities that could cause unnecessary distress.
Choice D rationale:
Stuffed animals might be a comforting option for the child. However, the child might also experience pain or discomfort when handling stuffed animals due to their condition. It's better to choose activities that don't involve physical contact that could potentially exacerbate the child's symptoms.
Choice E rationale:
Board games are a suitable choice for a child with osteomyelitis. They provide mental stimulation and entertainment without requiring excessive physical activity. Board games also promote social interaction if played with others, which is important for the child's emotional well-being during their hospital stay.
Correct Answer is D
Explanation
The correct answer is choice D. It is a belief common at this age.
Choice A rationale:
The statement does not suggest a failed attempt to develop a conscience. The scenario described is more related to the cognitive development of an 8-year-old child. Children at this age often have magical thinking and may interpret events, such as illness, as punishments for perceived wrongdoing. This is a normal aspect of their cognitive development rather than a reflection of a failed attempt to develop a conscience.
Choice B rationale:
While beliefs about punishment and consequences are present in many religions, the scenario is not about a general religious belief but rather a specific belief held by the individual child. This belief is reflective of the child's cognitive understanding and not necessarily a religious teaching common to most religions.
Choice C rationale:
The belief is not necessarily suggestive of excessive family pressure. While family dynamics can influence a child's beliefs and behaviors, the scenario describes a typical cognitive developmental stage where children are still learning to differentiate between reality and their own thoughts, leading to magical thinking and unique interpretations.
Choice D rationale:
The belief is indeed common at this age. During middle childhood, children often exhibit concrete operational thinking, which includes a tendency to interpret events in a self-centered and concrete manner. Beliefs like the one described in the scenario, where the child connects her illness to perceived bad behavior and potential consequences, are characteristic of this developmental stage.
