Question 1 of 5
After a discussion with the healthcare provider, the parents of an infant with patent ductus arteriosus (PDA) ask the nurse to explain once again what PDA is. How should the nurse respond?
Correct Answer: D
Rationale: Patent ductus arteriosus (PDA) is an abnormal connection between the pulmonary artery and the aorta. In a fetus, the ductus arteriosus is a normal connection between these two vessels, allowing blood to bypass the lungs. However, it should close shortly after birth. When it remains open (patent), it leads to PDA. Choices A, B, and C do not accurately describe PDA. Choice A describes an enlarged aorta, choice B describes a ventricular septal defect, and choice C describes pulmonary stenosis, which are different cardiac conditions.
Question 2 of 5
The nurse is caring for a child who has been admitted for a sickle cell crisis. What would the nurse do first to provide adequate pain management?
Correct Answer: D
Rationale: Initiating pain assessment with a standardized pain scale is crucial in effectively managing pain during a sickle cell crisis. This initial step helps the nurse understand the severity of the pain, which guides subsequent interventions. Administering medications, such as NSAIDs or meperidine, should only be done after a thorough pain assessment to ensure appropriate and individualized treatment. Using guided imagery and therapeutic touch may be beneficial as adjunct interventions, but they should not replace the essential first step of assessing the pain level accurately.
Question 3 of 5
A nurse is reviewing the laboratory report of a child with tetralogy of Fallot that indicates an elevated RBC count. What does the nurse identify as the cause of the polycythemia?
Correct Answer: B
Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs in response to chronic hypoxia, leading the body to increase red blood cell production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect that results in reduced oxygen levels in the blood, the body compensates by producing more red blood cells. Choice A is incorrect as low tissue oxygen needs would not trigger polycythemia. Choice C, diminished iron levels, is not the cause of polycythemia in this case. Choice D, hypertrophic cardiac muscle, is unrelated to the pathophysiology of polycythemia in tetralogy of Fallot.
Question 4 of 5
What explanation should the nurse give a parent about the purpose of a tetanus toxoid injection for their child?
Correct Answer: B
Rationale: The correct answer is B: Long-lasting active immunity is conferred. Tetanus toxoid injection works by stimulating the child's body to produce its antibodies, providing long-lasting active immunity. Choice A is incorrect because passive immunity is not conferred for life; it is temporary and involves receiving antibodies rather than producing them internally. Choice C is incorrect as the immunity conferred by the tetanus toxoid injection is not lifelong natural immunity but rather active immunity stimulated by the body's immune response. Choice D is also incorrect since passive natural immunity is not conferred by the tetanus toxoid injection, and it is not temporary.
Question 5 of 5
What finding would the nurse expect to assess in a child with hypothyroidism?
Correct Answer: D
Rationale: Weight gain is the expected finding in a child with hypothyroidism. Hypothyroidism leads to a slowed metabolism, which can result in weight gain. Choices A, B, and C are not typical findings in hypothyroidism. Nervousness and heat intolerance are more commonly associated with hyperthyroidism, where the body is in a state of overactivity. Smooth velvety skin is not a characteristic sign of hypothyroidism.
