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.

Answer and Explanation

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 A

Explanation

Choice A rationale:

Increased appetite is a common side effect of corticosteroid therapy. Corticosteroids are known to affect various metabolic processes, and one of the effects is an increase in appetite. This can lead to weight gain, especially when the increased calorie intake is not balanced by physical activity.

Choice B rationale:

Fever is not a typical side effect of corticosteroid therapy. Corticosteroids are often used to reduce inflammation and suppress the immune response, which can help in managing conditions like autoimmune diseases, allergies, and inflammatory disorders. Fever is not a direct result of corticosteroid administration.

Choice C rationale:

Weight loss is not a common side effect of corticosteroid therapy. In fact, corticosteroids are more likely to cause weight gain due to their influence on appetite, metabolism, and fluid retention.

Choice D rationale:

Hypertension (high blood pressure) can indeed be a side effect of corticosteroid therapy. Corticosteroids can lead to sodium and water retention, which can contribute to increased blood pressure, particularly in individuals who are already at risk for hypertension. However, among the options provided, increased appetite is a more directly associated side effect of corticosteroid therapy.

A. Tachycardia. B. Constipation. C. Hyperthermia. D. Vomiting. E. Hypotension.

Correct Answer is ["A","C","D"]

Explanation

The correct answers are choices A, C, and D: Tachycardia, Hyperthermia, and Vomiting.

Choice A rationale:

Tachycardia. Tachycardia, an abnormally fast heart rate, is a classic manifestation of thyroid storm. In this life-threatening condition, there is an excessive release of thyroid hormones, leading to increased metabolic rate and subsequent cardiovascular effects such as tachycardia.

Choice B rationale:

Constipation. This choice is incorrect for thyroid storm. Hyperthyroidism typically leads to increased bowel motility and can cause diarrhea rather than constipation.

Choice C rationale:

Hyperthermia. This is a correct choice. Thyroid storm is associated with severe hyperthermia due to the increased metabolic rate caused by excessive thyroid hormones. The body's temperature regulation is disrupted, leading to dangerously high body temperatures.

Choice D rationale:

Vomiting. This is a correct choice. Gastrointestinal symptoms, including vomiting and nausea, can occur in thyroid storm due to the heightened metabolic state. Thyroid storm affects various systems, including the gastrointestinal system, leading to symptoms like vomiting.

Choice E rationale:

Hypotension. This choice is incorrect for thyroid storm. Thyroid storm is more likely to cause hypertension rather than hypotension due to the increased cardiac output and sympathetic stimulation.
