Certified Pediatric Nurse Exam Practice Questions Questions
Question 1 of 5
Hemangiomas are the most common benign tumors of infancy, occurring more in full-term infants. Of the following, the most common risk factor of development of hemangioma is
Correct Answer: B
Rationale: Female infants are at higher risk for developing hemangiomas.
Question 2 of 5
If a patient has severe hyperkalemia, it is possible to administer calcium gluconate intravenously to:
Correct Answer: D
Rationale: Calcium gluconate is administered intravenously in the setting of severe hyperkalemia to antagonize the effects of potassium on the heart. Hyperkalemia can lead to dangerous cardiac arrhythmias due to the changes in membrane potential of cardiac cells caused by increased extracellular potassium levels. Administration of calcium gluconate helps stabilize the cardiac cell membrane potential, protecting against the risk of life-threatening arrhythmias. It doesn't provide an immediate decrease in serum potassium levels (Choice A) or prevent transient renal failure (TRF) (Choice B). Therefore, the correct answer is D, as calcium gluconate primarily acts to counteract the effects of hyperkalemia on the heart.
Question 3 of 5
Which of the following immunoglobulins is first produced during an acute infection?
Correct Answer: C
Rationale: IgM is the first immunoglobulin produced during an acute infection. It is the first class of antibodies secreted by B cells in response to an antigenic challenge. IgM antibodies are produced initially in primary immune responses and play a crucial role in activating the complement system. IgG is produced after IgM and is the most abundant immunoglobulin in the secondary immune response. IgE is responsible for allergic reactions, and IgD's function is not fully understood but is believed to be involved in the activation of B cells.
Question 4 of 5
Stroking the newborn's cheek along the side of the mouth causes the newborn to turn the head toward that side and begin to suck. This is which reflex?
Correct Answer: C
Rationale: The described reflex involving stroking the newborn's cheek along the side of the mouth causing the newborn to turn the head toward that side and begin to suck is known as the rooting reflex. This reflex is essential for newborns to find the nipple and start breastfeeding. Stroking the cheek triggers the baby to turn towards the stimulus, helping them locate the source of food for feeding.
Question 5 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
