Nursing Elites

1. Melena, the passage of black, tarry stools, suggests bleeding from which source?

• A. The perianal or rectal area
• B. The upper gastrointestinal (GI) tract
• C. The lower GI tract
• D. Hemorrhoids or anal fissures

Correct answer: B

Rationale: Melena indicates bleeding from the upper GI tract. The black, tarry appearance of the stool results from the partial digestion of blood as it passes through the intestines, typically originating from sources like the stomach or duodenum. Lower GI bleeding usually presents as bright red blood in the stool, originating from sources like the colon or rectum. Choices A, C, and D are incorrect because melena specifically points to upper GI bleeding rather than issues in the perianal/rectal area, lower GI tract, or hemorrhoids/anal fissures.

2. The clinic nurse is teaching parents about physiologic anemia that occurs in infants. What statement should the nurse include about the cause of physiologic anemia?

• A. Maternally derived iron stores are depleted in the first 2 months.
• B. Fetal hemoglobin results in a shortened survival of red blood cells.
• C. The production of adult hemoglobin decreases in the first year of life.
• D. Low levels of fetal hemoglobin depress the production of erythropoietin.

Correct answer: B

Rationale: Physiologic anemia is caused by the transition from fetal to adult hemoglobin, with fetal hemoglobin having a shorter lifespan, leading to a temporary decrease in red blood cells.

3. The nurse is caring for a child receiving chemotherapy with the following orders: Zantac 70 mg IV in normal saline 30 mL to infuse over 30 minutes. The nurse should set the infusion pump to deliver how many mL/hour?

• A. 60 mL/hour
• B. 45 mL/hour
• C. 30 mL/hour
• D. 15 mL/hour

Correct answer: A

Rationale: The correct answer is A: 60 mL/hour. The total volume to be infused is 30 mL over 30 minutes. To calculate the infusion rate in mL/hour, divide the total volume by the total time in hours. In this case, 30 mL / 0.5 hours = 60 mL/hour. Choice B, 45 mL/hour, is incorrect as it does not correspond to the calculated infusion rate. Choices C and D, 30 mL/hour and 15 mL/hour respectively, are also incorrect based on the calculation.

4. What changes could the school nurse implement at the school to help reduce students’ risk for developing type 2 diabetes?

• A. Increase the amount of daily physical activity.
• B. Decrease the amount of daily physical activity.
• C. Test each child’s urine monthly.
• D. Teach parents to avoid administering aspirin to their child.

Correct answer: A

Rationale: Increasing physical activity helps improve insulin sensitivity and can prevent or delay the onset of type 2 diabetes in children. Regular physical activity is a key component in managing weight and reducing the risk of chronic diseases. Decreasing physical activity (Choice B) would not be beneficial in reducing the risk of type 2 diabetes. Testing each child’s urine monthly (Choice C) is not directly related to preventing type 2 diabetes. Teaching parents to avoid administering aspirin to their child (Choice D) is important for Reye's syndrome prevention but not directly related to reducing the risk of type 2 diabetes.

5. The nurse is teaching parents about expected language development for their 6-month-old infant. The nurse recognizes the parents understand the teaching if they make which statement?

• A. Our baby should comprehend the word no.
• B. Our baby knows the meaning of saying mama.
• C. Our baby should be able to say three to five words.
• D. Our baby should begin to combine syllables, such as dada.

Correct answer: D

Rationale: At 6 months, infants typically begin to combine syllables like "dada" or "mama," but they do not yet understand the meaning of these words.
