Extract:
Question 1 of 5
A paediatric home care nurse schedules a visit to the home of a 4-week-old newborn who had a low thyroxine (T4) and a high thyroid stimulating hormone (TSH) at birth, and was diagnosed with congenital hypothyroidism or cretinism. Which instruction is most important for the nurse to provide the parents of this child?
Correct Answer: A
Rationale: Administering supplemental thyroid hormone daily is critical to replace deficient hormone, preventing developmental delays in congenital hypothyroidism.
Question 2 of 5
A 16-year-old adolescent with acute myelocytic leukemia is receiving chemotherapy via an implanted medication port at the outpatient oncology clinic. Which action should the nurse implement when the infusion is complete?
Correct Answer: C
Rationale: Flushing the mediport with saline and heparin prevents clot formation, maintaining patency for future use, which is a standard post-infusion procedure.
Question 3 of 5
The nurse is providing education to a group of adolescents about smoking prevention. Which approach should the nurse include to incorporate Piaget's cognitive development theory of formal operations?
Correct Answer: A
Rationale: Classifying health behaviors as healthy and unhealthy engages abstract thinking and categorization, aligning with Piaget's formal operations stage, which emphasizes hypothetical reasoning.
Question 4 of 5
To maintain patency of the ductus arteriosus, the nurse administers a prescribed dose of prostaglandin intravenously (IV) to a week-old infant diagnosed with transposition of the great vessels. Based on which finding should the nurse stop the medication administration immediately?
Correct Answer: A
Rationale: A heart rate of 50 beats/minute indicates bradycardia, a serious adverse effect of prostaglandin, requiring immediate cessation of the medication.
Question 5 of 5
Which nursing problem has the highest priority when providing preoperative care for an infant born with bladder exstrophy?
Correct Answer: D
Rationale: Risk for infection is the highest priority due to the exposed bladder in bladder exstrophy, which increases the risk of serious infections requiring immediate attention.
