What symptoms should a nurse expect in a 6-week-old infant admitted for evaluation of suspected pyloric stenosis?
Projectile vomiting.
Effortless regurgitation.
Metabolic acidosis.
Distended abdomen.
The Correct Answer is A
Choice A rationale
Projectile vomiting is a common symptom in infants with pyloric stenosis. This is due to the narrowing of the pylorus, the muscular valve at the bottom of the stomach, which prevents breast milk or formula from passing through to the small intestine.
Choice B rationale
Effortless regurgitation is not typically associated with pyloric stenosis. The hallmark symptom of pyloric stenosis is projectile vomiting.
Choice C rationale
Metabolic acidosis is not a typical symptom of pyloric stenosis. The hallmark symptom of pyloric stenosis is projectile vomiting.
Choice D rationale
While a distended abdomen can occur in some cases of pyloric stenosis, it is not the most common symptom. The hallmark symptom of pyloric stenosis is projectile vomiting.

Correct Answer is A
Explanation
Choice A rationale
Tinea Capitis, also known as scalp ringworm, is primarily transmitted through direct contact with infected personal items such as towels, combs, or hats.
Choice B rationale
Exposure to worm eggs through bare feet is not a mode of transmission for Tinea Capitis. This is more commonly associated with a different type of parasitic infection known as hookworm.
Choice C rationale
Sitting on worm eggs is not a mode of transmission for Tinea Capitis. This is a misconception and there is no scientific evidence to support this claim.
Choice D rationale
Airborne droplet transmission is not a mode of transmission for Tinea Capitis. Tinea Capitis is caused by a type of fungus, not a virus or bacteria, and it does not spread through the air via droplets.
Correct Answer is A
Explanation
Choice A rationale
Pediculosis capitis, also known as head lice, is a common condition in children. One of the definitive indications of this condition is the presence of firmly attached white particles on the hair, which are the eggs or “nits” of the lice.
Choice B rationale
While itching and scratching of the head can be a symptom of pediculosis capitis, it is not a definitive indication as it can be caused by other conditions such as dandruff or dermatitis.
Choice C rationale
Patchy areas of hair loss are not typically associated with pediculosis capitis. They could indicate a different condition, such as alopecia areata or tinea capitis.
Choice D rationale
Thick yellow-crusted lesions on a red base are not a symptom of pediculosis capitis. This description is more consistent with impetigo, a bacterial skin infection.
