Certified Pediatric Nurse Exam Practice Questions Questions
Question 1 of 5
What is the pathophysiologic mechanism of cystic fibrosis leading to obstructive lung disease?
Correct Answer: C
Rationale: Cystic fibrosis (CF) is caused by mutations in the CFTR gene, leading to altered transport of sodium and chloride ions in and out of epithelial cells. This results in the production of secretions that are low in sodium chloride, leading to thickened mucus. The abnormally thick, abundant secretions from mucous glands in the respiratory tract can obstruct the airways, leading to chronic, diffuse obstructive pulmonary disease in almost all patients with CF. This process impairs mucociliary clearance, predisposing individuals to recurrent lung infections, inflammation, and ultimately bronchiectasis. This mechanism is a key factor in the pathophysiology of cystic fibrosis-associated obstructive lung disease.

Question 3 of 5
When planning the education for the parents of a child with type 1 diabetes mellitus, which of the following should the nurse include?
Correct Answer: B
Rationale: When planning education for the parents of a child with type 1 diabetes mellitus, the nurse should include rotating insulin injection sites. This is important to prevent lipohypertrophy, which is the buildup of fat under the skin, and to ensure consistent absorption of insulin. Rotating injection sites helps to maintain healthy tissue and promotes better insulin effectiveness in managing blood sugar levels. It is a key component of proper diabetes care and helps to reduce the risk of complications associated with continuous injection in the same area.
Question 4 of 5
the therapeutic management of children with b-thalassemia major consists primarily of which of the following?
Correct Answer: D
Rationale: The primary therapeutic management of children with beta-thalassemia major involves frequent blood transfusions. This is necessary because beta-thalassemia major is a severe form of thalassemia where there is a significant reduction in the production of hemoglobin. Blood transfusions help to increase the levels of normal hemoglobin in the body, improving symptoms related to anemia and preventing complications such as growth failure and organ damage. Other treatments such as iron chelation therapy to manage iron overload and supportive measures like adequate hydration are also important, but frequent blood transfusions are the cornerstone of managing beta-thalassemia major.
Question 5 of 5
while planning therapeutic care for type ï‰ diabetes mellitus you would expect treatment plan to include:
Correct Answer: D
Rationale: Type 1 diabetes mellitus is characterized by the body's inability to produce insulin. Therefore, the mainstay of treatment for type 1 diabetes is insulin therapy. Insulin injections are necessary to replace the insulin that the body is unable to produce on its own. While physical exercise and dietary management are important components of managing diabetes, in the case of type 1 diabetes, insulin is an essential part of the treatment plan to control blood glucose levels effectively and prevent complications. Oral hypoglycemic agents, on the other hand, are typically used in the treatment of type 2 diabetes, where the body's insulin production may be insufficient or ineffective.
