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?

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 and 3-month-old infant are visiting the well-baby clinic for a routine examination. What should the nurse include in the accident prevention teaching plan?

Correct answer: D

Rationale: The correct answer is to test the temperature of water before bathing. This is crucial in preventing burns, which is a significant risk for infants due to their sensitive skin. Infants have delicate skin that can be easily burned by water that is too hot. Removing small objects from the floor (Choice A) is important to prevent choking hazards but not directly related to burns. Covering electric outlets with safety plugs (Choice B) is essential to prevent electrocution but does not address the risk of burns specifically. Removing toxic substances from low areas (Choice C) is necessary to prevent poisoning but is not directly related to burns. Therefore, the priority in this scenario is to prevent burns by ensuring the water temperature is safe for the infant.

3. .A child with type 1 diabetes mellitus is being discharged from the hospital. What is important for the nurse to include in the discharge teaching?

Correct answer: D

Rationale: Recognizing signs of hypoglycemia is crucial for managing type 1 diabetes mellitus and preventing complications.

4. What is important to include in discharge instructions for parents of a child who has had a tonsillectomy?

Correct answer: B

Rationale: Encouraging fluid intake is essential in the discharge instructions for a child who has had a tonsillectomy. It helps keep the throat moist, aids in preventing dehydration, and promotes healing. Gargling with salt water is not typically recommended after a tonsillectomy as it may irritate the surgical site. Providing the child with hard candy is not advisable as it can irritate the throat and potentially cause harm. Applying heat to the neck is also not recommended post-tonsillectomy as it can increase swelling and discomfort in the surgical area.

5. When explaining a viral disease that begins with malaise and a highly pruritic rash starting on the abdomen, spreading to the face and proximal extremities, and potentially leading to severe complications, which childhood disease is a nurse discussing with members of a grammar school’s Parent-Teachers Association?

Correct answer: C

Rationale: The correct answer is Chickenpox (varicella). This viral disease typically starts with malaise and a highly pruritic rash that begins on the abdomen and then spreads to the face and proximal extremities. Chickenpox can result in serious complications such as pneumonia and encephalitis. Rubella (German measles) presents with a milder rash and is less pruritic than chickenpox. Rubeola (measles) is characterized by a rash that spreads from the head to the trunk. Scarlet fever is caused by group A Streptococcus bacteria and is not a viral illness.
