Nursing Elites

1. How is the diagnosis of Hirschsprung disease confirmed in a 1-month-old infant admitted to the pediatric unit?

• A. Colonoscopy
• B. Rectal biopsy
• C. Multiple saline enemas
• D. Fiberoptic nasoenteric tube

Correct answer: B

Rationale: Rectal biopsy is the definitive diagnostic procedure for Hirschsprung disease in infants. It confirms the absence of ganglion cells in the affected bowel segment, which is characteristic of Hirschsprung disease. Colonoscopy (Choice A) is not typically used for confirmation as it may not provide a definitive result. Multiple saline enemas (Choice C) are utilized in the treatment of meconium ileus, a complication of cystic fibrosis, and not in the diagnosis of Hirschsprung disease. Fiberoptic nasoenteric tube (Choice D) is not a diagnostic tool for Hirschsprung disease; it is commonly used for gastrointestinal decompression or feeding purposes but does not confirm the diagnosis.

2. A 4-year-old fell from a third-story window and landed on her head. She is semiconscious with slow, irregular breathing and bleeding from her mouth. After performing a jaw-thrust maneuver with simultaneous stabilization of her head, what should you do next?

• A. Suction the oropharynx
• B. Insert a nasopharyngeal airway
• C. Initiate positive pressure ventilations
• D. Administer oxygen via mask

Correct answer: A

Rationale: In this scenario, the patient is experiencing airway compromise due to the fall and potential oropharyngeal obstruction from bleeding. Performing a jaw-thrust maneuver with head stabilization helps maintain the airway patency. The next step should be to suction the oropharynx to clear any blood or secretions, which can obstruct the airway and lead to aspiration. Inserting a nasopharyngeal airway may worsen bleeding or cause further injury to the patient's airway. Initiating positive pressure ventilations can be ineffective if the airway is not cleared first. Administering oxygen via mask is not the immediate priority; ensuring a patent airway by suctioning takes precedence.

3. A 3-year-old child ingests a substance that may be a poison. The parent calls a neighbor who is a nurse and asks what to do. What should the nurse recommend the parent do?

• A. Administer syrup of ipecac.
• B. Call the poison control center.
• C. Take the child to the emergency department.
• D. Give the child bread dipped in milk to absorb the poison.

Correct answer: B

Rationale: In cases of potential poisoning, the best immediate action to take is to call the poison control center. Administering syrup of ipecac is no longer recommended as it can lead to complications such as aspiration and may interfere with subsequent treatments. Taking the child to the emergency department should only be done if advised by the poison control center or if the child is showing severe symptoms. Giving bread dipped in milk to absorb the poison is not an appropriate or effective treatment for poisoning, as it does not address the toxicity of the ingested substance and may delay appropriate medical interventions.

4. Where should the child admitted with injuries that may be related to abuse be placed?

• A. In a private room
• B. With an older, friendly child
• C. With a child of the same age
• D. In a room near the nurses’ desk

Correct answer: D

Rationale: The correct answer is to place the child in a room near the nurses’ desk. This placement allows for close monitoring of the child's condition and facilitates quick intervention if necessary. Placing the child in a private room (Choice A) may not provide the necessary level of oversight in cases of suspected abuse. Additionally, placing the child with an older, friendly child (Choice B) or a child of the same age (Choice C) may not be appropriate due to the need for careful monitoring and protection in cases of potential abuse.

5. The nurse is reviewing the laboratory test results of a child with Addison's disease. What would the nurse expect to find?

• A. Hypernatremia
• B. Hyperkalemia
• C. Hyperglycemia
• D. Hypercalcemia

Correct answer: B

Rationale: In Addison's disease, adrenal insufficiency leads to decreased aldosterone production. This results in impaired sodium retention and potassium excretion, leading to hyperkalemia. Therefore, the correct answer is hyperkalemia (choice B). Hypernatremia (choice A) is less likely because of the loss of sodium in Addison's disease. Hyperglycemia (choice C) and hypercalcemia (choice D) are not typically associated with Addison's disease and are less likely to be present in this condition.
