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 of a 2-year-old child tells a nurse at the clinic, 'Whenever I go to the store, my child has a screaming tantrum, demanding a toy or candy on the shelves. How can I deal with this situation?' What is the nurse’s best response?

• A. “Attempt to distract the child by offering a toy.”
• B. “Say nothing and allow the tantrum to continue until it ends.”
• C. “Have a babysitter stay with the child at home until the child outgrows this behavior.”
• D. “Give the child the item while in the store, and when the child loses interest, return the item to the shelf.”

Correct answer: B

Rationale: The best approach in dealing with a child's tantrum is to not give in to their demands. By allowing the tantrum to continue until it ends, the child learns that this behavior is not effective in getting what they want. Offering a distraction (Choice A) might temporarily calm the child but does not address the underlying issue of the tantrum. Leaving the child with a babysitter (Choice C) does not teach the child how to handle such situations. Giving in to the child's demands (Choice D) reinforces the tantrum behavior.

3. A nurse is caring for an infant with a tentative diagnosis of hypertrophic pyloric stenosis (HPS). What is most important for the nurse to assess?

• A. Quality of the cry
• B. Signs of dehydration
• C. Coughing up feedings
• D. Characteristics of the stool

Correct answer: B

Rationale: The correct answer is B: Signs of dehydration. Infants with hypertrophic pyloric stenosis (HPS) are at high risk of dehydration due to frequent vomiting. Assessing for signs of dehydration, such as decreased urine output, dry mucous membranes, and sunken fontanelles, is crucial for early intervention and management. Choices A, C, and D are not the most critical assessments for HPS. The quality of the cry (choice A) may not provide as much relevant information in this case. Coughing up of feedings (choice C) may be a symptom but is not as crucial as assessing for dehydration. Characteristics of the stool (choice D) are important but assessing for signs of dehydration takes precedence due to the immediate risk it poses to the infant's health.

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

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

Correct answer: B

Rationale: The correct answer is B: Tissue oxygen needs. Polycythemia occurs as the body's response to chronic hypoxia by increasing RBC production to enhance oxygen delivery. In tetralogy of Fallot, a congenital heart defect, the heart's structure causes reduced oxygen levels in the blood. This chronic hypoxia stimulates the bone marrow to produce more red blood cells, leading to an elevated RBC count. Choice A is incorrect as low blood pressure is not directly related to polycythemia in this context. Choice C, diminished iron level, is not the cause of polycythemia in tetralogy of Fallot. Choice D, hypertrophic cardiac muscle, is not the primary cause of the elevated RBC count in this case.

5. The nurse is obtaining a health history from parents of a 4-month-old boy with congenital hypothyroidism. What would the nurse most likely assess?

• A. The child's growth is above normal for his age.
• B. The child is active and playful.
• C. The skin appears pink and healthy.
• D. It is difficult to keep the child awake.

Correct answer: D

Rationale: The correct answer is D. Congenital hypothyroidism in infants often leads to lethargy and difficulty staying awake due to low thyroid hormone levels. Assessing the child's ability to stay awake is crucial in identifying signs of hypothyroidism. Choices A, B, and C are incorrect because above-normal growth, being active and playful, and having healthy-looking skin are not typical manifestations of congenital hypothyroidism. Instead, infants with hypothyroidism may exhibit poor weight gain, decreased activity, and dry, pale skin.
