A nurse is conducting a group therapy session for several clients. The group is laughing at a joke one of the clients told, when a client who is schizophrenic jumps up and runs out of the room yelling. "You are all making fun of me!" The nurse should identify this behavior as which of the following characteristics of schizophrenia?

A. Projectile vomiting: Pyloric stenosis is a condition characterized by the narrowing of the pylorus, the opening between the stomach and the small intestine. This narrowing leads to obstruction of the gastric outlet, causing the stomach to become distended with food. When the infant feeds, the stomach fills up, but the food cannot pass through the narrowed pylorus efficiently. As a result, the infant forcefully expels the contents of the stomach in a characteristic manner known as projectile vomiting. Projectile vomiting is forceful, often occurring shortly after feeding, and the vomited material is usually not bile-stained.

B. Ridged abdomen: While abdominal distension can occur due to the buildup of gastric contents in pyloric stenosis, the term "ridged abdomen" is not typically associated with this condition. Instead, clinicians may palpate an olive-shaped mass in the right upper quadrant of the abdomen, which represents the hypertrophied pylorus. The ridged appearance may be more indicative of conditions such as peritonitis or muscular rigidity, rather than pyloric stenosis.

C. Distended neck veins: Distended neck veins are not typically associated with pyloric stenosis. This symptom is more commonly observed in conditions affecting the cardiovascular system, such as congestive heart failure. In pyloric stenosis, the primary manifestations are related to gastrointestinal obstruction, particularly projectile vomiting, rather than signs of circulatory compromise.

D. Red currant jelly stools: Red currant jelly stools are a characteristic finding in intussusception, a condition where one portion of the intestine telescopes into another, causing obstruction and compromise of the blood supply. This leads to the passage of stools containing blood and mucus, resembling red currant jelly in appearance. Pyloric stenosis primarily affects gastric emptying and does not typically result in bloody stools. Instead, the hallmark symptom is projectile vomiting due to gastric outlet obstruction.

A. Launder the child's clothing with fabric softener: Fabric softeners can contain chemicals and fragrances that may irritate the skin of a child with eczema. It's advisable to wash the child's clothing with a mild, fragrance-free detergent and avoid the use of fabric softeners.

B. Dress the child in woolen clothes during cold months: Wool can be irritating to sensitive skin and may exacerbate eczema symptoms. It's best to dress the child in soft, breathable fabrics such as cotton to minimize irritation.

C. Give the child bubble baths every day: Bubble baths can strip the skin of its natural oils and exacerbate eczema symptoms. It's recommended to limit baths to every other day or less frequently and to use lukewarm water without added bubbles or harsh soaps.

D. Apply a topical corticosteroid ointment to the affected area: This is the correct choice. Topical corticosteroids are commonly used to reduce inflammation and relieve itching associated with eczema. They help to control eczema flare-ups and manage symptoms effectively. However, it's important to follow the healthcare provider's instructions regarding the frequency and duration of corticosteroid use and to apply them only to the affected areas of the skin.
