Correct Answer: B

Rationale: The correct answer is to 'Avoid gluten.' Celiac disease is an autoimmune disorder triggered by gluten consumption, a protein found in wheat, barley, and rye. By avoiding gluten-containing foods, individuals with celiac disease can prevent damage to their small intestine and manage their symptoms effectively. Choice A, 'Avoid dairy products,' is incorrect as dairy is not directly related to celiac disease. Choice C, 'Avoid high-fat foods,' and Choice D, 'Avoid foods high in sugar,' are incorrect as they are not primary dietary concerns in managing celiac disease. The main focus should be on eliminating gluten sources from the diet.

Correct Answer: C

Rationale: The correct answer is C: Hyperpigmentation and hypotension. These findings are classic signs of Addison disease, caused by adrenal insufficiency. Hyperpigmentation results from increased ACTH stimulating melanin production, and hypotension occurs due to mineralocorticoid deficiency. Choices A, B, and D are incorrect. Arrested height and increased weight are not typical of Addison disease. Thin, fragile skin and multiple bruises are seen in conditions like Cushing's syndrome, not Addison disease. Blurred vision and enuresis are not characteristic symptoms of Addison disease.

Correct Answer: B

Rationale: The sweat chloride test is the gold standard diagnostic test for cystic fibrosis as it measures the concentration of chloride in sweat. In cystic fibrosis, there is an abnormal transport of chloride across epithelial membranes, leading to elevated sweat chloride levels. A chest X-ray may show characteristic changes in the lungs associated with cystic fibrosis, but it is not a definitive diagnostic test. Pulmonary function tests assess lung function but do not specifically diagnose cystic fibrosis. Sputum culture may identify respiratory infections but does not confirm the diagnosis of cystic fibrosis.

Correct Answer: C

Rationale: Visible peristalsis and weight loss are classic clinical manifestations of pyloric stenosis. Visible peristalsis refers to the wave-like movements in the abdomen caused by the stomach trying to empty into the intestines due to the obstruction at the pylorus. Weight loss is often seen due to inadequate feeding and vomiting associated with this condition. Choices A, B, and D are not typical of pyloric stenosis. Abdominal rigidity and pain on palpation are more indicative of conditions like peritonitis. A rounded abdomen and hypoactive bowel sounds are more suggestive of conditions like constipation or bowel obstruction. Distention of the lower abdomen and constipation are not specific to pyloric stenosis and may be seen in various gastrointestinal issues.

Correct Answer: A

Rationale: The nurse should suggest offering the child a choice of two juices. Giving the child a choice between two options empowers them to make a decision, fostering a sense of control, and increasing the likelihood of cooperation. This approach respects the child's autonomy while addressing the parent's concern about the child's fluid intake. Choices B, C, and D are incorrect because distracting the child, offering the glass in a firm manner, or displaying anger are not effective strategies for encouraging a 24-month-old child to drink juice.
