Nursing Elites

1. Several types of long-term central venous access devices are used. What is a benefit of using an implanted port (e.g., Port-a-Cath)?

• A. You do not need to pierce the skin for access.
• B. It is easy to use for self-administered infusions.
• C. The patient does not need to limit regular physical activity, including swimming.
• D. The catheter cannot dislodge from the port even if the child plays with the port site.

Correct answer: C

Rationale: Implanted ports like the Port-a-Cath are fully implanted under the skin, allowing the child to maintain regular physical activities, including swimming, without the risk of dislodging the catheter. Piercing the skin is still required for access, and self-administration is more complex.

2. During a routine health assessment, the nurse notes that an 8-month-old infant has a significant head lag. Which is the most appropriate action?

• A. Recheck head control at the next visit
• B. Teach the parents appropriate exercises
• C. Schedule the child for further evaluation
• D. Refer the child for further evaluation if the anterior fontanel is still open

Correct answer: C

Rationale: Significant head lag at 8 months is concerning and warrants further evaluation, as it may indicate developmental delays or neurological issues.

3. What diagnostic test allows visualization of renal parenchyma and renal pelvis without exposure to external-beam radiation or radioactive isotopes?

• A. Renal ultrasonography
• B. Computed tomography
• C. Intravenous pyelography
• D. Voiding cystourethrography

Correct answer: A

Rationale: Renal ultrasonography provides imaging of the renal parenchyma and pelvis without the risks associated with radiation or radioactive isotopes, making it a safer option, especially for children.

4. According to Piaget, which principle supports a nine-year-old child's understanding that an arm will look the same when the IV is removed?

• A. The principle of conservation
• B. The principle of transductive reasoning
• C. The principle of identity
• D. The principle of reflex abilities

Correct answer: A

Rationale: The correct answer is A, the principle of conservation. Piaget's principle of conservation relates to a child's ability to understand that certain properties of objects remain unchanged despite modifications in their appearance. In this case, the child's understanding that an arm will look the same after the IV is removed demonstrates conservation of appearance. Choice B, transductive reasoning, involves making faulty generalizations based on specific instances and does not apply in this context. Choice C, the principle of identity, pertains to recognizing objects as the same even if they undergo transformations, which is not directly relevant to the scenario. Choice D, reflex abilities, refers to automatic responses to stimuli and is unrelated to the child's understanding of the arm's appearance post-IV removal.

5. A four-year-old boy is admitted to the hospital with leg pain and fever. He is pale-looking and has bruises over various areas of his body. The physician suspects acute lymphoblastic leukemia (ALL). Which test would be used to confirm the diagnosis?

• A. Bone marrow aspirate
• B. Red blood cell count
• C. Lumbar puncture
• D. Bone scan

Correct answer: A

Rationale: A bone marrow aspirate is the definitive test to confirm acute lymphoblastic leukemia (ALL) in this case. It allows for the examination of leukemic cells in the bone marrow, providing a direct assessment of the disease. Red blood cell count (Choice B) is not specific for diagnosing leukemia but may show anemia commonly seen in leukemia patients. Lumbar puncture (Choice C) is used to assess central nervous system involvement, not primarily for confirming ALL. Bone scan (Choice D) is not a standard diagnostic test for ALL and is mainly used for evaluating bone metastases in other conditions.
