1. What does a positive correlation between two variables indicate?

• A. One variable causes the other.
• B. Both variables move in the same direction.
• C. Both variables move in opposite directions.
• D. There is no relationship between the variables.

Correct answer: B

Rationale: A positive correlation between two variables indicates that they move in the same direction. This means that as one variable increases (or decreases), the other variable also increases (or decreases). Choice A is incorrect because correlation does not imply causation; it only shows a relationship between variables. Choice C is incorrect as it describes a negative correlation where variables move in opposite directions. Choice D is incorrect as a positive correlation implies a relationship between the variables.

2. What is the primary intervention for a child experiencing a tonic-clonic seizure?

• A. Administer intravenous fluids
• B. Place the child in a prone position
• C. Protect the child from injury
• D. Perform mouth-to-mouth resuscitation

Correct answer: C

Rationale: The primary intervention for a child experiencing a tonic-clonic seizure is to protect them from injury. Placing the child in a prone position can be dangerous as it may lead to further harm due to the risk of aspiration or airway obstruction. Administering intravenous fluids is not recommended during a seizure. Performing mouth-to-mouth resuscitation is also not indicated as the child will resume breathing spontaneously after the seizure stops. Ensuring the child's safety and preventing injury by removing harmful objects and cushioning their head is essential until the seizure subsides.

3. Parents of a 6-month-old child, diagnosed with iron deficiency anemia, ask why it was not diagnosed earlier. What should the nurse say?

• A. Are you sure your child has iron deficiency anemia?
• B. Maternal stores of iron are depleted at about 6 months.
• C. This anemia is caused by blood loss.
• D. The child may not have had it for a long time.

Correct answer: B

Rationale: The correct answer is B: 'Maternal stores of iron are depleted at about 6 months.' Iron deficiency anemia becomes apparent around 6 months of age when the infant's iron stores, primarily received from the mother during pregnancy, are depleted. This timing coincides with the introduction of solid foods, which may lack sufficient iron. Choices A, C, and D are incorrect because they do not address the specific reason why iron deficiency anemia is typically diagnosed around 6 months of age.

4. How should a healthcare professional approach the care of a child with a newly diagnosed type 1 diabetes?

• A. Emphasize the importance of blood glucose monitoring
• B. Avoid insulin therapy
• C. Encourage a high-carbohydrate diet
• D. Recommend alternative therapies only

Correct answer: A

Rationale: Corrected Rationale: Emphasizing the importance of blood glucose monitoring is crucial for managing type 1 diabetes effectively. Monitoring blood glucose levels helps in maintaining optimal control of the condition, adjusting treatment plans as necessary, and preventing complications. Choice B is incorrect because insulin therapy is the mainstay treatment for type 1 diabetes to regulate blood sugar levels. Choice C is incorrect because while diet is important, encouraging a high-carbohydrate diet can lead to fluctuations in blood sugar levels. Choice D is incorrect because alternative therapies should not replace standard medical treatment like insulin therapy in type 1 diabetes management.

5. What is a key sign of meningitis in an infant?

• A. Increased appetite
• B. Bulging fontanel
• C. Decreased respiratory rate
• D. Elevated blood pressure

Correct answer: B

Rationale: A bulging fontanel is a key sign of meningitis in infants, indicating increased intracranial pressure due to inflammation of the meninges. This can lead to the fontanel bulging. Choices A, C, and D are incorrect. Increased appetite is not typically associated with meningitis in infants; instead, they may have poor feeding. A decreased respiratory rate is not a common sign of meningitis in infants. Elevated blood pressure is also not a typical finding in infants with meningitis.
