Nursing Elites

1. A nurse is working with the local community on promoting physical fitness for children. The nurse encourages the community to develop programs that meet the needs of the school-aged child for physical activity, based on the understanding that this age group requires how much physical activity daily?

• A. 30 minutes
• B. 60 minutes
• C. 90 minutes
• D. 15 minutes

Correct answer: B

Rationale: The correct answer is B: 60 minutes. School-aged children require at least 60 minutes of physical activity daily according to recommendations. This level of activity helps in promoting overall health, development, and well-being. Choice A (30 minutes) is incorrect as it falls short of the recommended duration. Choice C (90 minutes) is excessive and not the standard guideline for this age group. Choice D (15 minutes) is insufficient to meet the physical activity needs of school-aged children.

2. Why is it difficult to assess a child’s dietary intake?

• A. No systematic assessment tool has been developed
• B. Biochemical analysis for assessing nutrition is expensive
• C. Families usually do not understand much about nutrition
• D. Recall of food consumption is frequently unreliable

Correct answer: D

Rationale: The correct answer is D. Recall of food intake, especially amounts eaten, is often unreliable. While systematic tools like the 24-hour recall and dietary history questionnaires exist, recall can still be challenging in accurately assessing a child's dietary intake. Choices A, B, and C are incorrect because systematic assessment tools do exist, biochemical analysis is not the primary method for dietary assessment, and families' understanding of nutrition may vary but is not the main reason for the difficulty in assessing a child's dietary intake.

3. The nurse is caring for a child with Beta Thalassemia. Which child is in a group most at risk for Beta Thalassemia?

• A. A three-year-old girl of Mediterranean descent.
• B. A ten-year-old boy of Hispanic descent.
• C. A young girl of African descent.
• D. A baby of European descent.

Correct answer: A

Rationale: Corrected Rationale: Beta Thalassemia is most common in individuals of Mediterranean descent, such as those from Italy, Greece, and the Middle East. This genetic disorder affects hemoglobin production and can lead to severe anemia. Choice A is the correct answer as individuals of Mediterranean descent are at the highest risk for Beta Thalassemia. Choices B, C, and D are incorrect as they do not belong to the population group most at risk for this genetic disorder.

4. During an otoscopic examination on an infant, in which direction is the pinna pulled?

• A. Up and back
• B. Up and forward
• C. Down and back
• D. Down and forward

Correct answer: C

Rationale: For infants, the pinna is pulled down and back to straighten the ear canal and allow proper visualization of the tympanic membrane during otoscopic examination.

5. Which pediatric disorder is associated with a 'boot-shaped' heart on a chest x-ray?

• A. Tetralogy of Fallot
• B. Transposition of the great arteries
• C. Coarctation of the aorta
• D. Ventricular septal defect

Correct answer: A

Rationale: The correct answer is A: Tetralogy of Fallot. Tetralogy of Fallot is often associated with a 'boot-shaped' heart appearance on a chest x-ray due to the characteristic heart anatomy in this condition. This appearance is caused by the combination of pulmonary stenosis, overriding aorta, ventricular septal defect, and right ventricular hypertrophy. Choice B, Transposition of the great arteries, is incorrect because it presents with a 'egg-on-a-string' appearance on x-ray due to the abnormal position of the aorta and pulmonary artery. Choice C, Coarctation of the aorta, typically presents with rib notching on x-ray. Choice D, Ventricular septal defect, does not produce the 'boot-shaped' heart appearance seen in Tetralogy of Fallot.
