What is an advantage of peritoneal dialysis?
Treatments are done in hospitals.
Protein loss is less extensive
Parents and older children can perform treatments.
Dietary limitations are not necessary.
The Correct Answer is C
A. Treatments are done in hospitals is incorrect because peritoneal dialysis is typically performed at home, not exclusively in hospitals. Home-based treatment is one of its key distinctions from hemodialysis.
B. Protein loss is less extensive is incorrect because peritoneal dialysis is associated with greater protein loss compared with hemodialysis due to protein leakage across the peritoneal membrane.
C. Parents and older children can perform treatments is correct because peritoneal dialysis can be done at home after proper training. This allows greater independence, flexibility, and a more normal lifestyle for children and families.
D. Dietary limitations are not necessary is incorrect because dietary and fluid restrictions are still required with peritoneal dialysis, although they may be less strict than with hemodialysis.

Correct Answer is A
Explanation
A. Sweat chloride test is correct because it is the gold standard diagnostic test for cystic fibrosis. In CF, mutations in the CFTR gene lead to abnormal chloride transport in epithelial cells. This results in elevated chloride levels in sweat, typically ≥60 mmol/L in children, which confirms the diagnosis.
B. Genetic testing for CFTR mutations is incorrect as the sole diagnostic tool because not all CF mutations are detectable, and testing may identify carriers or atypical variants. While genetic testing is useful for confirmation or family counseling, it is not the first-line diagnostic test.
C. Chest x-ray is incorrect because, although it may reveal hyperinflation, bronchiectasis, or infiltrates indicative of chronic lung disease in CF, it cannot confirm the diagnosis. Imaging is supportive but not diagnostic.
D. Pulmonary function tests (PFTs) are incorrect because these tests assess lung function and airflow limitation, but they are not diagnostic for CF, especially in young children who may not be able to perform the tests reliably.
Correct Answer is ["A","B","D"]
Explanation
A. Fruity (ketone) breath odor is correct because diabetic ketoacidosis (DKA) causes the production of ketone bodies, including acetone, which gives the breath a sweet, fruity odor. This is a classic and easily recognizable sign of DKA.
B. Dehydration is correct because hyperglycemia leads to osmotic diuresis, causing excessive urination and fluid loss. Children with DKA often present with dry mucous membranes, poor skin turgor, tachycardia, and decreased urine output, all indicating dehydration.
C. Hypotension without dehydration is incorrect because hypotension in DKA is typically secondary to dehydration and volume depletion. Hypotension in the absence of dehydration is not characteristic of DKA.
D. Kussmaul respirations (deep, rapid breathing) are correct because metabolic acidosis in DKA stimulates the respiratory center to blow off excess carbon dioxide. These deep, labored respirations are a compensatory mechanism and are a hallmark sign of severe DKA.
E. Weight gain is incorrect because children with DKA usually experience weight loss, not gain, due to fat and muscle breakdown, dehydration, and insulin deficiency.
