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. Which information about hemophilia will the nurse include in the teaching plan for the parents of a child diagnosed with hemophilia?

Correct answer: B

Rationale: The correct answer is B: Hemophilia is an X-linked recessive disorder, primarily affecting males and passed from mothers to sons. It involves a deficiency in clotting factors, leading to prolonged bleeding. Choice A is incorrect as hemophilia is not autosomal dominant. Choice C is incorrect as hemophilia does not involve platelets. Choice D is incorrect as hemophilia is not autosomal recessive.

3. The school nurse is explaining to older school children that obesity increases the risk for which disorders? (Select all that apply.)

Correct answer: D

Rationale: Obesity increases the risk for conditions like asthma, hypertension, dyslipidemia, and altered glucose metabolism, but not typically irritable bowel disease.

4. A two-month-old infant who has gastroesophageal reflux is thriving without other complications. Which instruction should the nurse include in the teaching plan?

Correct answer: B

Rationale: The correct instruction for a two-month-old infant with gastroesophageal reflux who is thriving without complications is to thicken the formula with rice cereal. This can help reduce reflux by increasing the weight of the formula, making it less likely to be regurgitated. Placing the infant in the Trendelenburg position after feeding (Choice A) is not recommended as it can increase the risk of aspiration. Continuous nasogastric feedings (Choice C) are not typically indicated for uncomplicated reflux in infants. Giving larger, less frequent feeds (Choice D) can worsen reflux symptoms by overloading the stomach.

5. Following treatment for iron deficiency anemia, the physician orders lab tests. Which lab value would indicate an improvement in the child’s condition?

Correct answer: C

Rationale: A high reticulocyte count indicates that the bone marrow is producing more red blood cells, which is a sign of recovery from anemia as the body replenishes its iron stores and increases hemoglobin levels. Low hemoglobin (Choice A) would indicate ongoing anemia rather than improvement. A normal platelet count (Choice B) and low hematocrit (Choice D) are not specific indicators of improvement in iron deficiency anemia.
