1. Which is the most frequently used test for measuring visual acuity?

Correct answer: A

Rationale: The Snellen letter chart is the most commonly used test for measuring visual acuity, particularly in school-age children and adults.

2. A 3-year-old child with Hirschsprung disease is hospitalized for surgery. A temporary colostomy will be necessary. How should the nurse prepare this child?

Correct answer: B

Rationale: Preparation is essential even for a young child, as they need to adjust to the temporary colostomy and understand the changes to their body, which can be confusing and distressing without proper explanation.

3. An infant weighed 8 lb at birth and was 18 inches in length. What weight and length should the infant be at 5 months of age?

Correct answer: C

Rationale: By 5 months, an infant's weight should typically double from birth, and length should increase by approximately 50%.

4. The caregiver asks why the 6-month-old infant needs to have solid foods when breast milk is such a good source of nutrition. What would be the best response by the nurse?

Correct answer: A

Rationale: The correct response is A. Solid foods, especially iron-fortified cereals, are introduced to meet the infant's increased nutritional needs, including iron, which breast milk alone may not provide adequately. Choice B is incorrect because the extrusion reflex is related to the tongue-thrust reflex, not the nutritional needs of the infant. Choice C is incorrect as breastfeeding does not become painful when the infant gets more teeth, and it is not a reason for introducing solid foods. Choice D is incorrect as the infant's interest in trying new skills is not a primary reason for introducing solid foods at this age.

5. When assessing an infant with intussusception, what type of stool would the nurse expect to find?

Correct answer: B

Rationale: The correct answer is B: Currant-jelly stool. This type of stool, which is red and mucous-like, is a classic sign of intussusception in infants. Choice A (Soft, seedy stool) is incorrect as it does not specifically describe the characteristic stool associated with intussusception. Choice C (Ribbon-like stool) is incorrect; ribbon-like stool may be seen in conditions like colon cancer, not intussusception. Choice D (Soft and pasty stool) is also incorrect as it does not match the typical stool finding in intussusception.
