Nursing Elites

1. The nurse is teaching a group of students about myelination in a child. Which statement by the students indicates that the teaching was successful?

• A. Myelination continues into adolescence and beyond.
• B. The process occurs in a cephalocaudal (head-to-toe) pattern.
• C. Myelination decreases the speed of nerve impulses.
• D. Myelination decreases the specificity of nerve impulses.

Correct answer: B

Rationale: The correct answer is B. Myelination occurs in a cephalocaudal (head-to-toe) pattern, improving nerve function progressively. Choice A is incorrect as myelination continues into adolescence and beyond, not just during childhood. Choice C is incorrect because myelination actually increases the speed of nerve impulses rather than decreasing it. Choice D is incorrect as myelination enhances the specificity of nerve impulses, making them more efficient and precise rather than less specific.

2. A parent arrives in the emergency clinic with a 3-month-old baby who says, “My baby stopped breathing for a while.” The infant continues to have difficulty breathing, with prolonged periods of apnea. Which assessment data should alert the nurse to suspect shaken baby syndrome (SBS)?

• A. Birth occurred before 32 weeks’ gestation
• B. Lack of stridor and adventitious breath sounds
• C. Previous episodes of apnea lasting 10 to 15 seconds
• D. Retractions and use of accessory respiratory muscles

Correct answer: D

Rationale: Retractions and the use of accessory respiratory muscles can be signs of respiratory distress, which may indicate trauma such as shaken baby syndrome (SBS). Shaken baby syndrome can result in brain injury and respiratory compromise, leading to breathing difficulties. Choices A, B, and C are less likely to be associated with SBS. Birth before 32 weeks’ gestation is more related to prematurity rather than SBS. The lack of stridor and adventitious breath sounds, as well as previous episodes of apnea lasting 10 to 15 seconds, are not specific indicators of SBS.

3. A 3-year-old child with a history of frequent respiratory infections is being evaluated for cystic fibrosis. What diagnostic test should the nurse anticipate will be ordered?

• A. Chest X-ray
• B. Sweat chloride test
• C. Pulmonary function test
• D. Sputum culture

Correct answer: B

Rationale: The sweat chloride test is the gold standard diagnostic test for cystic fibrosis as it measures the concentration of chloride in sweat. In cystic fibrosis, there is an abnormal transport of chloride across epithelial membranes, leading to elevated sweat chloride levels. A chest X-ray may show characteristic changes in the lungs associated with cystic fibrosis, but it is not a definitive diagnostic test. Pulmonary function tests assess lung function but do not specifically diagnose cystic fibrosis. Sputum culture may identify respiratory infections but does not confirm the diagnosis of cystic fibrosis.

4. Which treatment is instituted for the therapeutic management of minimal change nephrotic syndrome?

• A. corticosteroids
• B. antihypertensive agents
• C. long-term diuretics
• D. increased fluids to promote diuresis

Correct answer: A

Rationale: Corticosteroids are the mainstay of treatment for minimal change nephrotic syndrome as they help reduce inflammation and decrease proteinuria. Antihypertensive agents are used to manage high blood pressure often associated with kidney disease but are not the primary treatment for this condition. Long-term diuretics are not typically used in the management of minimal change nephrotic syndrome as they can worsen fluid and electrolyte imbalances. Increasing fluids to promote diuresis is not recommended in this condition as it can lead to further fluid retention and edema.

5. A nurse is planning an initial home care visit to a mother who gave birth to a high-risk infant. For what time of day should the nurse schedule the visit to be most productive?

• A. When the husband is out of the home.
• B. At a time when the mother is feeding the infant.
• C. At a time that is convenient for the family.
• D. When the nurse can spend time with the family.

Correct answer: C

Rationale: Scheduling the visit at a time that is convenient for the family is crucial for ensuring the family's receptiveness and availability, making the visit more productive. Choosing a time when the mother is feeding the infant (choice B) may not necessarily align with the family's overall convenience and may disrupt the feeding routine. Similarly, scheduling the visit when the husband is out of the home (choice A) might not be optimal as it may exclude an important family member and potentially impact the support system. While spending time with the family (choice D) is important, the primary focus should be on accommodating the family's schedule to maximize the effectiveness of the visit.
