Certified Pediatric Nurse Exam Practice Questions Questions
Question 1 of 5
A nurse is admitting a child to the hospital with a diagnosis of giardiasis. Which medication should the nurse expect to be prescribed?
Correct Answer: A
Rationale: Giardiasis is an intestinal infection caused by a protozoan parasite called Giardia lamblia. Metronidazole (Flagyl) is the drug of choice for treating giardiasis in children and adults. It is an antibiotic that is effective against a wide range of anaerobic bacteria and protozoa, including Giardia lamblia. Metronidazole works by disrupting the DNA of the parasite, leading to its death. It is usually well-tolerated and has a high cure rate for giardiasis. Amoxicillin clavulanate (Augmentin) is a combination antibiotic used to treat bacterial infections, not parasitic infections like giardiasis. Clarithromycin (Biaxin) is primarily used for treating bacterial infections, such as respiratory tract infections. Prednisone (Orapred) is a corticosteroid used to reduce
Question 2 of 5
A 7 year old boy came to OPD with history of difficulty in rising up from sitting position. Examination reveals hypertrophy of calf muscles with trendelenburg gait. The most likely diagnosis is:
Correct Answer: B
Rationale: Duchenne muscular dystrophy typically presents in early childhood with difficulty rising from a seated position (Gower's sign), calf muscle hypertrophy, and Trendelenburg gait.
Question 3 of 5
The nurse is caring for a school-age child with a tinea capitis (ringworm) infection. What should the nurse expect the therapeutic management of this child to include?
Correct Answer: A
Rationale: The nurse should expect the therapeutic management of a school-age child with tinea capitis to include administering oral griseofulvin. Griseofulvin is an antifungal medication commonly used to treat fungal infections like tinea capitis. Topical or oral antibiotics are not effective in treating fungal infections. Applying topical sulfonamides is also not a recommended treatment for tinea capitis. Burow solution compresses are used to provide relief for inflammatory skin conditions and are not specific treatments for fungal infections like tinea capitis.
Question 4 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.
