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 A
Explanation
The correct answer is choice A.
Choice A rationale:
Drawing is the most appropriate activity for developing fine motor skills in school-age children. Drawing involves precise hand movements, control of a writing instrument, and attention to detail. These skills contribute to fine motor skill development and hand-eye coordination.
Choice B rationale:
Singing is not directly related to fine motor skill development. While it can promote cognitive and social development, it does not require the same level of fine motor control as activities like drawing or writing.
Choice C rationale:
Swimming is a gross motor activity that focuses more on large muscle groups and overall coordination. It does not specifically target the refinement of fine motor skills.
Choice D rationale:
Soccer is also a gross motor activity that involves running, kicking, and coordination with teammates. While it promotes physical fitness and coordination, it does not emphasize the fine motor control required for activities like drawing.
Correct Answer is B
Explanation
The correct answer is choice B: Lesions may extend to hairline or neck.
Choice A rationale:
Central clearing is not a prominent indicator of Tinea capitis. Tinea capitis is a fungal infection of the scalp and hair shafts, commonly caused by dermatophytes like Trichophyton species. The characteristic features include scaling, erythema, pustules, and hair loss. Unlike some other fungal infections, Tinea capitis does not typically have central clearing.
Choice B rationale:
Lesions extending to the hairline or neck is a correct aspect to include in education about Tinea capitis. The infection usually starts as small, scaly patches on the scalp and can progress to larger areas. It can extend to the hairline, neck, and even eyebrows and eyelashes. This is important information to convey to ensure proper recognition and timely treatment.
Choice C rationale:
Transmission of Tinea capitis mostly occurs from human-to-human rather than from dogs. While some animals can carry fungal infections that affect the skin, Tinea capitis is primarily spread through direct contact with an infected person or contaminated objects like combs, hats, and pillows.
Choice D rationale:
The appearance of Tinea capitis is not usually unilateral. This condition often presents with multiple, scattered areas of involvement on the scalp. It can cause varying degrees of inflammation, scaling, and hair loss in different areas, which may not follow a unilateral pattern.
