Nursing Elites

1. An 8-year-old child diagnosed with meningitis is to undergo a lumbar puncture. What should the nurse explain is the purpose of this procedure?

• A. To measure the pressure of cerebrospinal fluid
• B. To obtain a sample of cerebrospinal fluid for analysis
• C. To relieve intracranial pressure
• D. To assess the presence of infection in the spinal fluid

Correct answer: B

Rationale: A lumbar puncture is performed to obtain a sample of cerebrospinal fluid for analysis. This fluid is then examined for signs of infection, bleeding, or other abnormalities. Measuring the pressure of cerebrospinal fluid is typically done during the procedure itself, but it is not the primary purpose of the lumbar puncture. While a lumbar puncture can indirectly help relieve intracranial pressure by removing excess cerebrospinal fluid, this is not its primary purpose. Assessing the presence of infection in the spinal fluid is part of the analysis that follows the collection of the sample, making it a secondary outcome of the procedure.

2. A parent calls the clinic because their child has ingested a small amount of household bleach. What should the nurse advise?

• A. Administer activated charcoal
• B. Induce vomiting immediately
• C. Call the poison control center
• D. Take the child to the emergency department

Correct answer: C

Rationale: The correct answer is to advise the parent to call the poison control center. When a child ingests household bleach, it is important to seek guidance from professionals who can provide specific and immediate advice on managing the situation. Administering activated charcoal (Choice A) is not recommended for household bleach ingestion. Inducing vomiting immediately (Choice B) can lead to further complications and is not the recommended first response. Taking the child to the emergency department (Choice D) should be done based on the advice received from the poison control center.

3. A parent receives a note from the school that a student in class has head lice. The parent calls the school nurse to ask how to check for head lice. What instructions should the nurse provide?

• A. Ask the child where it itches.
• B. Check to see if your dog has ear mites.
• C. Look along the scalp line for white dots.
• D. Observe between the fingers for red lines.

Correct answer: C

Rationale: The correct answer is to look along the scalp line for white dots (nits) when checking for head lice. White dots/nits are the eggs of head lice and are commonly found attached to the hair shaft near the scalp. This method helps identify if head lice are present. Choice A is incorrect as itching alone may not be a definitive sign of head lice; it could be due to other reasons. Choice B is irrelevant as ear mites in dogs are not related to head lice infestation in humans. Choice D is also incorrect as observing between the fingers for red lines is not a method for checking head lice.

4. A nurse is reviewing the laboratory report of a child with tetralogy of Fallot that indicates an elevated RBC count. What does the nurse identify as the cause of the polycythemia?

• A. Low tissue oxygen needs
• B. Tissue oxygen needs
• C. Diminished iron levels
• D. Hypertrophic cardiac muscle

Correct answer: B

Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs in response to chronic hypoxia, leading the body to increase red blood cell production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect that results in reduced oxygen levels in the blood, the body compensates by producing more red blood cells. Choice A is incorrect as low tissue oxygen needs would not trigger polycythemia. Choice C, diminished iron levels, is not the cause of polycythemia in this case. Choice D, hypertrophic cardiac muscle, is unrelated to the pathophysiology of polycythemia in tetralogy of Fallot.

5. 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. place the patient in the recovery position

Correct answer: A

Rationale: In this scenario, the 4-year-old is presenting with signs of airway compromise due to the fall. After performing a jaw-thrust maneuver to open the airway while stabilizing the head to prevent further injury, the next step should be to suction the oropharynx. Suctioning helps to clear any blood or secretions from the mouth and throat, ensuring a clear airway for proper breathing. Inserting a nasopharyngeal airway or initiating positive pressure ventilations would be premature without first ensuring the airway is clear. Placing the patient in the recovery position is not indicated at this point as the focus should be on managing the airway.
