Nursing Elites

1. Which laboratory test would be most important for the nurse to assess when caring for a toddler suspected of having cystic fibrosis?

• A. Liver enzymes
• B. Serum calcium
• C. Sweat chloride test
• D. Urine creatinine

Correct answer: C

Rationale: The sweat chloride test is the primary diagnostic test for cystic fibrosis. Cystic fibrosis is characterized by abnormal transport of chloride and sodium across epithelial cell membranes, leading to increased chloride in sweat. This test is crucial for diagnosing cystic fibrosis in suspected cases. Liver enzymes (Choice A), serum calcium (Choice B), and urine creatinine (Choice D) are not specific tests for cystic fibrosis and would not provide the necessary information for diagnosis in this case.

2. According to Freud’s developmental theory, infancy is a stage of:

• A. Orality
• B. Latency
• C. Genitality
• D. Anality

Correct answer: A

Rationale: In Freud’s psychosexual development theory, the oral stage is the first stage and occurs during infancy. It focuses on activities involving the mouth, such as sucking and feeding. This stage is crucial for the child's development as it forms the basis for trust and attachment. Choices B, C, and D are incorrect as latency refers to the stage during middle childhood where sexual impulses are suppressed, genitality refers to the final stage focusing on mature sexual relationships, and anality refers to the stage occurring during the toddler years where toilet training plays a significant role.

3. Parents of a child who will need hemodialysis ask the nurse, What are the advantages of a fistula over a graft or external access device for hemodialysis? (Select all that apply.)

• A. It is ready to be used immediately.
• B. All below
• C. There is less restriction of activity with a fistula.
• D. It produces dilation and thickening of the superficial vessels.

Correct answer: A

Rationale: A fistula typically has fewer complications, allows for greater freedom of movement, and involves natural vessel changes that improve dialysis efficiency. However, it is not ready for immediate use, which is why it may take weeks to mature before it can be used.

4. A 5-year-old is hospitalized with a fractured femur. Which pain assessment tool is appropriate for this child?

• A. CRIES Scale
• B. Faces Pain Rating Scale
• C. SUN Scale
• D. NIPS Scale

Correct answer: B

Rationale: The Faces Pain Rating Scale is appropriate for assessing pain in children who can express their feelings visually. For a 5-year-old child who can communicate effectively, using a tool like the Faces Pain Rating Scale, which uses facial expressions to indicate pain levels, is more suitable than the CRIES Scale (used for neonates), the SUN Scale (used for infants), or the NIPS Scale (used for preterm and term newborns).

5. The nurse is admitting a child with severe isotonic dehydration. Which intravenous fluid should the nurse anticipate the doctor to order initially to replace fluids?

• A. 0.9% normal saline
• B. D5 0.2% (1/4) normal saline
• C. D5W
• D. Albumin

Correct answer: A

Rationale: In the case of severe isotonic dehydration, the initial fluid of choice is 0.9% normal saline. This solution is preferred because it helps to restore both fluids and electrolytes effectively. Options B, C, and D are not suitable for the initial management of severe isotonic dehydration. D5 0.2% (1/4) normal saline (Choice B) is a hypotonic solution and might worsen the imbalance. D5W (Choice C) is a hypotonic solution that does not contain electrolytes essential for rehydration. Albumin (Choice D) is a colloid solution used for specific indications like hypoproteinemia or hypoalbuminemia, not for initial rehydration in severe dehydration.
