Certified Pediatric Nurse Exam Practice Questions Questions
Question 1 of 5
Which of the following is the most common permanent disability in childhood?
Correct Answer: C
Rationale: Cerebral palsy is the most common permanent disability in childhood among the options provided. It is a group of disorders that affect movement and muscle coordination due to damage or abnormal development in the brain. Cerebral palsy can occur before, during, or shortly after birth, and it is a lifelong condition that impacts a child's ability to move, maintain balance, and posture. Scoliosis, muscular dystrophy, and developmental dysplasia of the hip (DDH) are also significant conditions that can lead to disabilities in children, but they are not as prevalent as cerebral palsy in terms of permanent disabilities in childhood.
Question 2 of 5
Mr. Reyea complains of hearing ringing noises. The nurse recognizes that this assessment suggests injury of the
Correct Answer: D
Rationale: The eighth cranial nerve is the vestibulocochlear nerve, which is responsible for transmitting auditory and balance information from the inner ear to the brain. Complaints of hearing ringing noises, also known as tinnitus, suggest a dysfunction or injury to the vestibulocochlear nerve. Tinnitus is a common symptom of various inner ear disorders such as noise-induced hearing loss, Meniere's disease, or acoustic neuroma. Therefore, the nurse should investigate further for possible issues related to the vestibulocochlear nerve when a patient reports hearing ringing noises.
Question 3 of 5
The MOST common cause of sleeping difficulty in the first 2 months of life is
Correct Answer: B
Rationale: Colic is a frequent cause of sleep difficulties in young infants.
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.
Question 5 of 5
An 8-year-old child is receiving digoxin (Lanoxin). The nurse should notify the practitioner and withhold the medication if the apical pulse is less than _____ beats/min.
Correct Answer: A
Rationale: In pediatric patients receiving digoxin, the nurse should notify the practitioner and withhold the medication if the apical pulse is less than 60 beats/min in an 8-year-old child. Digoxin can cause bradycardia as a side effect, and a low heart rate (bradycardia) can indicate toxicity. Monitoring the apical pulse rate before administering digoxin is essential to ensure the child's safety and prevent complications related to digoxin toxicity.
