A nurse is conducting a teaching session for parents of infants. The nurse explains that which behavior indicates that an infant has developed object permanence?
- A. Recognizes familiar face, such as mother
- B. Recognizes familiar object, such as bottle
- C. Actively searches for a hidden object
- D. Secures objects by pulling on a string
Correct Answer: C
Rationale: Object permanence is the understanding that objects continue to exist even when they can't be seen, heard, or touched. When an infant actively searches for a hidden object, it demonstrates that the infant has developed object permanence. This behavior implies that the infant understands that the object still exists even though it is temporarily out of sight. This usually emerges around 8-12 months of age, according to Piaget's theory of cognitive development. The other choices do not specifically relate to the concept of object permanence as directly as actively searching for a hidden object does.
A 3-day-old neonate has a large, soft, painless mass involving the head and neck region that mostly transilluminate; CT scan reveals a cystic mass involving the neck and intrathoracic mediastinum. The BEST modality for treatment of this neonate is
- A. surgical resection
- B. injection sclerosing agent
- C. laser therapy
- D. systemic interferon therapy
Correct Answer: A
Rationale: Surgical resection is the definitive treatment for cystic hygroma.
When evaluating the effectiveness of nursing interventions for sinusitis discomfort, which of the following does the nurse assess?
- A. WBC count
- B. Capillary refill
- C. Amount and color of sinus drainage
- D. Comfort level
Correct Answer: C
Rationale: When evaluating the effectiveness of nursing interventions for sinusitis discomfort, assessing the amount and color of sinus drainage is crucial. Changes in these aspects can provide valuable information about the progression of the sinusitis and the effectiveness of the interventions being implemented. Increased or purulent sinus drainage can indicate infection or inflammation, while clearer drainage may suggest improvement. Monitoring these parameters helps the nurse make informed decisions about continuing, modifying, or discontinuing interventions to manage the patient's sinusitis discomfort effectively. Evaluating WBC count, capillary refill, and comfort level are also important assessments in certain situations, but assessing the amount and color of sinus drainage is most directly related to sinusitis symptoms.
During starvation, the body slows metabolic processes and growth to minimize the need for nutrients. With the rapid reinstitution of feeding after starvation refeeding syndrome may occur. Of the following, the major changes that may occur with refeeding syndrome typically affect
- A. electrolytes
- B. serum proteins
- C. hormones
- D. liver enzymes
Correct Answer: A
Rationale: Refeeding syndrome primarily affects electrolytes, particularly phosphorus, potassium, and magnesium, which can become dangerously depleted due to rapid shifts in metabolism.
Appropriate intervention is vital for many children with heart disease in order to go on to live active, full lives. Which of the following outlines an effective nursing intervention to decrease cardiac demands and minimize cardiac workload?
- A. Feeding the infant over long periods
- B. Allowing the infant to have her way to avoid conflict
- C. Scheduling care to provide for uninterrupted rest periods
- D. Developing and implementing a consistent care plan
Correct Answer: C
Rationale: The most appropriate intervention to decrease cardiac demands and minimize cardiac workload in children with heart disease is to schedule care to provide uninterrupted rest periods. By allowing the child to rest without interruptions, their heart will not have to work as hard, promoting better overall cardiac function. This intervention focuses on promoting rest and recovery, which is crucial for children with heart disease to maintain optimal cardiac health. Feeding the infant over long periods may not necessarily decrease cardiac demands, and allowing the infant to have her way to avoid conflict is not related to cardiac workload. Developing and implementing a consistent care plan is important but may not directly decrease cardiac demands as effectively as scheduling care for uninterrupted rest periods.
